Hey guys,
Have searched a while, but found no solutions for this, so here goes.
Have stock Galaxy Nexus with ICS 4.0.1, build ITL41F, installed Google Music v4.0.9 (with online sync).
Music is synced with google's online music service (even though I'm in UK, worked-around US-only restriction), and plays nicely when the screen is on. Once I switch the screen off (press power button), one of two things happen:
- if sampling rate of a song is below 48,000 Hz -- everything continues as normal.
- if sampling rate is 48,000Hz and up -- every one/couple of seconds music stutters, and jerks. Feels like I'm listening to dusty ol' record!
The 48kHz part is my theory, compared a few mp3s that stutter and some that don't. This seems to happen irrespective of bps rate and other parameters (albeit haven't checked all).
Few people on the forum with similar symptoms (on other phones) suggested it has something to do with cpu throttle during sleep, and that by forcing it to higher frequencies during sleep this could be solved.
Installed setCPU (which required rooting) and forced phone to 1,200MHz in sleep as a trial, and the songs still were stuttering.
Anyone with a similar experience?
Prime suspect would be google_music.apk which is in beta i believe, and... well, i guess then I'm out. What do you guys think? Any idea what might be causing this?
This is my first android phone, so I'm not sure even how I'd go about submitting a bug, if that's indeed the beta version of music at fault here. Any pointers?
Ta,
Dan

That, is weird - because I am facing this with Winamp so I've switched to Google Music to play my music.
Does anyone else face something similar?
Can you do me a favor and play something you know that stutters, and then try it over a bluetooth connection.
I'm curious if this is also related to the static I get when the screen is off and output is analog outputs - digital (bluetooth) works fine.
same here with poweramp... switched to googlemusic... now i have only stutters over the phone speaker..
Same thing happen to me with google music and pandora. Thought it was the connection.

I get the same using the Music app (have WinAmp but doesn't seem to integrate with the lockscreen so don't use it) as soon as the screen goes off (either timeout or manual) you can hear the music slow down and start to stutter, tap the power button, screen comes on and music goes back to normal.
Have noticed it's not all songs, but have't looked into the differences between those that do and those that don't.
Are these locally stored songs that this is happening on? So far so good here but I have been streaming from the Google Music cloud.. I wonder if the CPU is struggling during the underclocked sleep condition with local files that are high bitrate...
Mine are local files, not tried from another source.
I've used both, streaming from Google cloud, and when songs are available offline in the music app -- still stuttering. Haven't tried any other method though.
As for trying to stream over Bluetooth, haven't got any speakers/earphones that could receive the stream at home. Going to try my luck with a local pcworld, if they let me.
I haven't had any problems with Google Music stuttering while the screen is off, but I have had it crash frequently while listening to music and multitasking. I experienced a similar problem with Rhapsody as well.

totally true! thought my phone was a lemon at first.luckily i didnt return it.
yep having the same exact issue. on speaker its just fine. when i plug in headphones or aux to car stereo and screen goes off it stutters / skips or whatever you want to call it.
Turn the screen on and its fine. However doesnt happen to all music. This was streaming from google music for me.
I'm pretty positive you guys have same exact problem as many other people. So far no one has take my suggestion of playing those same songs that stutter, and play them over bluetooth. I bet you don't get any more stutters. I think it has to do with analog outputs vs digital. To output analog, the phone has to use the DAC (digital to analog converter). When it outputs over bluetooth, there is no conversion, and the music is in digital form and transmitted in digital form
If someone can try this I would appreciate it. And you'd be helping everyone find a common denominator in this problem.
Also be sure to star this bug on google code http://code.google.com/p/android/issues/detail?id=22444#c6
Can someone post an mp3 this is happening to them with? I have a ton of them and I have not seen this problem yet.

Didn't I PM you a link the other day? I thought it was to you. I didn't click the box to save it to my sent box so I can't just look it up :[
Circling back. I recreated the problem with luxferro's 48KHz mp3. Seems whatever happens on this phone to play mp3 with the screen off cannot handle that sample rate. Any 44.1KHz mp3 works fine.

There was another thread like this. The current workaround is to enable the Equalizer for Google Music. You don't have to actually use it (leave it on default) but this solves the problem.

I guess with the eq on its forcing the CPU to get involved even when in low power mode. Unfortunately I believe that was causing other issues with crashing. Since I don't use 48KHz mp3 I'll leave it off.

For poweramp try settings... Audio engine.. Advanced tweets and change the audio buffer size.

Having the EQ turned on seems to work, just set it to flat and turned the 3d effect down. Guess it'll use less extra battery than using a 'keep awake' app like I was doing.
As the title states I got the MHL today. Output to a 73" 1080p DLP, 55" Samsung LED 7000 series smart TV, 50" 1080p Panasonic Plasma, and 39" 1080p westinghouse LED all produce similar results... and if I do say so myself, it's really bad.
Lets see where to begin:
The Good:
-Watching 1080p content from local or network storage produces a pretty good picture
-Text is sharp, webpages look great
-Phone charges while mirroring
The Bad:
-Audio output is descent at best through HDMI, when connected with a very nice surround sound decoder it only decodes as "multi-channel", so DTS and other streams are not preserved on output
-Lag. And let me say this again... LAG. Don't even bother playing a game, it's unbearable. The phone experiences no lag while mirroring, but the output is about 1/3 the framerate.
-Lag on movies. On every TV the lag was exactly the same, whether I hardware decode or software decode the lag is present. Youtube videos look laggy even.
-Netflix does not properly mirror. I presume this is related to HDCP or copy prevention, but streaming HD content to the phone produces a nice widescreen image on the phone, but the output to the connected monitor is pure crap. Take a nice 720p HD movie, compress it using the bitrate of a low quality MP3, transmit it via AM radio to your least favorite country somehow, and then watch it on a ****ty color TV from the 1980's. This is my experience with Netflix output. Also, you can tell it is not "mirroring" because when you tap the screen, the position slider appears on the phone but not the TV.
-Cannot turn screen off while mirroring
All in all, I'm somewhat pissed off. In its present state I would have preferred the phone not support HDMI. I would accept this as a "Oh hey the phone doesn't technically support MHL HDMI mirroring but we hacked it and look what we can do" but this is definitely not a finished product to advertise. Anyone else experience similar problems? Anybody have HD output with no lag? Maybe I have a defective MHL adapter/phone?
I think you may have a defective adapter/cable. I got the adapter tip today and most of your cons were nonexistent for me -
Audio Output - I don't know much about audio but I have a 5.1 surround sound setup and it worked perfectly.
Lag - I had 0 lag. I played a racing game and watched a few episodes of Breaking Bad (MKV so the phone was working hard at decoding it too) and I had no lag.
Turning screen off - I see this as a pro since you cant accidentally turn it off while mirroring
But this brings me to my point about netflix...
Netflix has been horrible with MHL on my last 3 phones, including this one. If I try to watch a 16:9 HD show on netflix through MHL, it plays fine on the phone but becomes 4:3 on my 16:9 HDTV somehow. I don't know why this happens, but if there was a way to make it mirror exactly what was on the screen, that wouldn't happen.
I'm actually quite pleased since the signal is very solid with this phone. With previous phones, the signal constantly dropped and reconnected. I tried every cable but it was a no go.
The Netflix I don't believe is the phones fault directly, I think it has to do with Netflix restricting output. As for the lag, I will return the unit as defective if I can and get another one. Hopefully that's the problem, the lag is incredibly noticeable for me. Audio wise, it's not bad, but I don't see why it can't just output (or at least give as an option) uncompressed audio from the source. My main irk is the framerate I've seen, hopefully it's limited to this unit. Anybody else experience lag or more importantly not experience any?
I ran Netflix ok.. but same ratio issues as above... didn't look great but was ok. Any regular video files looked great.. but I had to order 2 adapters before I got the right one.

I also received my MHL adapter in the mail today. I like the picture quality and sound quality on my 42" 720p plasma, but I am wondering if it supports headphone port output somehow.
I got a connector also, but does seem to work with my monocable NHL,

I have a Samsung mhl and it works great
Sent using my Galaxy S III
I just used the official Samsung one today to deliver a training for a few new hires, and it worked perfectly. I had a full 10 slide powerpoint, afterwards I opened up the camera app and used the connected LCD screen as the viewfinder.
Issues with the MHL adapter lag, and possible fix
I have noticed similar problems as the OP. About an 1/8 of a second lag when trying to play SNES. For those of you who wanted to retro game with a bluetooth controller (like a PS3 sixaxis) I was able to get it to work. It could be my TV, but I got the lag down well below a second, enough so that you can play a game like donkey kong country and dodge opponents. The game plays at 30Hz which isn't the best frame rate, but fine for SNES.
The TV is a Samsung 1080p and there are two options that I enabled that seemed to help; video game mode, and BD mode. I don't think the TV should matter but I thought I should mention this. After much tinkering I realized that the phone is sending two different streams instead of exactly mirroring the phone's own stream. I think this is the case because when I was playing with settings I noticed in some cases it would send a landscape view to the TV when the phone's own display was in portrait mode. There were a couple other things that indicated that this is the case.
The Fix:
Anyways using a third party app like Titanium back up you need to freeze almost everything, anything that is not essential to running the game of your choice; this includes things like Verizon bloatware, Samsung bloat ware, s voice, maps, Facebook etc. You also have to turn off things like wifi, GPS, sync, etc. I also enabled force GPU rendering in the developer settings. Make sure you don't have a live background running. I also overclocked my phone to the max with setCPU. Also if you use an app like nova launcher you can make a back up of your settings and app placements which you can restore to keep your icon placements. I realize this is not a very viable fix, but this seemed to work for me.
End Fix
It's a pain, but worth it if you want a portable retro game machine. Samsung or someone at XDA needs to look into fixing this because I am pretty sure it is a software related issue. I hope anyone who bought a MHL adapter and wanted to retro game finds this useful.
So with the guys who have good results where you ordering it from.

Hey just an update for anyone having issues such as screen flashes and lag I did a little more research and found in Samsung documentation that when connected to hdmi the s3 disables the output when a text or phone call is received but this was not implemented. I found that the device still checks for phone use and texts when connected to mhl. I actually had random screen flashes at set intervals on my TV! I disabled the phone and sms and this seemed to stop the flashing and help with some lag. I also noticed if you restart the device with the MHL to hdmi cable inserted the connection is a tad better and it also fixes screen flashes. I wish the damn thing worked and I have already replaced the MHL to hdmi cable twice now, and the slight lag (noticable when gaming) seems to affect a lot of people. It could be a problem with the actual device and not the software which would suck

How is the Netflix playback on this unit? Does it have 1080p playback like the Nexus 7? Any sync issues with sound? Does it look great?
I'm asking this as I recently bought the Xperia Tablet Z and it has quite possibly the worst Netflix playback I've ever seen, especially for such a high end unit. My Nexus 7 or even my older IPad are miles better. It looks like I will be returning the Sony and perhaps ordering one of these.
Any other Netflix junkies here?

Cant get the sound and video to sync. Varies from right on, to half a sec lag or lead of sound throughout the movie. Very disappointing and annoying at the same time. Posted asking if anyone else had this issue but no replies...
This is true even after todays last OTA update. The video looks great - not sure about the resolution
I've had it intermittently. once when starting the office and then when playing Hatfield and McCoy's. exiting out each movie and restarting fixed it most of the time and other times just made it better but not perfect.the last two test just a few minutes ago played perfectly. I did install the latest ota yesterday so it could be that fixed it.
and for the op I can't say much about 1080p Netflix since I've lowered the stream in my prefs. my daughter plays Netflix all day and the highest throughput we can get out here is 6Mbps on a 150Gb limit. the week I gave my daughter her opacity a few Christmases ago she nearly used up all our bandwidth in 1 week!
1080p local videos are beautiful though!
I'm on the newest update and just tried The Avengers. Video quality is great (looks 1080 to me), sound syncs fine, but I did notice the video flickering a little within the first few minutes. Didn't appear for the rest of the movie.

Im also on the newest build, and i just added two movies avengers and transformers in HD to my queue, and played them and they seem to be working flawlessly, the sound is synced perfectly, no lag between movie and soundtrack. Quite pleased working better than the iPad. Lol
Can also verify - newest build. Netflix is working flawlessly. Extremely happy with the playback right now

After playing around with Netflix I realized that when I plug in the headphones (wired), the audio/video playback is flawless i.e. no sync issues. When I connect my Bluetooth stereo headset (LG tone) the I am having terrible audio/video sync problems. Don't know if it's a problem with this specific Bluetooth headset or a problem in general with the Bluetooth of the tablet. I will try other Bluetooth headsets to verify.
Im sorry if im reviving an old post but i need to know this ..
im about to buy this tablet and i love watching netflix.. Does the app Has HD playback ? Pleasee answer is the app working now?

This is a common issue with Bluetooth wireless speakers. I heard them talking about it on a Twit podcast recently. Try connecting via a wire and see if the problem goes away.

Every device I have lags on Bluetooth. You can't tell just playing audio (music) but with video the latency is apparent. The note works exactly the same.
Good to see this has good Netflix hope it's 1080p will be getting mines in a few days.
Hello,
Just wonder if I am alone on this one. I noticed today that when I stream music on my note3 to my car while being connected to the moto that the must quality dropped. I use Google play all access paid feature. This has never happened before when I didn't have the watch synced.
Has anyone else heard of this? I am going to try to use spotify tonight and see if it was a Google server issues or my signal.
Thank you
Custom rom?
It's possible the music streaming is maxing out the bluetooth and the watch updating itself is just too much, but for a Note 3 it should be no sweat...
I havent noticed any problem like that... you sure your audio quality from the play music itself isnt lower?
same here, no problem..same situation, same quality
Does anyone know how to NOT have Google music on the watch? I took it away from notification on the wear app but it still happens. I don't want to see what is playing or skip to next track on the watch.. For this reason and i'm sure its killing battery lift if I go on a long trip if it updates after each song.
I haven't noticed any problems. Nexus 5, All Access, with my BT speaker and in my Mazda, it works same as before I had the watch.

I notice the audio from my car cuts out or stutters. This is when I have my watch connected to my phone too. I never had this issue prior to the watch.
I'm using a LG G2 running Optimus 1.3.2 rom
On the latest PA Beta 2 Rom on my Nexus 5 and no issues connecting to my HTC Stereo clip. Used with spotify, poweramp, n7 player and other players as well.
I'm having an issue with audio dropping out and being interfered with too. Oneplus One, Moto 360, Audi Bluetooth audio. Very frustrating. Sometimes I can hear the quality level of the music change when it drops out, almost like it's trying different bitrates or codecs to fix the issue.
Least I am not the only one, but mine never actually drops. But I can just tell the quality go down. Like going from 256kb to 128kb..This is even music that loaded on my phone, Not spotify or Pandora.
Are you using ART or Dalvik runtime? This was happening to me after switching to Dalvik. Switching back to Dalvik solved it.
I noticed the audio quality drop as well on my HTC One m7, stock rooted. I first noticed it dropped slightly after getting a bluetooth obd reader but it wasn't enough to really worry about. Then, after getting my moto 360, the quality dropped even more to the point I had to stop using bluetooth for streaming music and use an auxiliary cable instead. So, it seems it's just using up too much of whatever bluetooth bandwidth is available so the audio quality drops in order to compensate.
I have this problem to, using a LG G3 with ART, I have to disconnect the moto 360 from the phone to have a good audio.
No problems here with my Note 3 connected to my M360 and Ford Sync.
This is a question I keep checking on too. Seems like the common factor for people not having issues drive a Ford, using Ford Sync.
I drive a Toyota [emoji107]
I've switched roms on my Lg G2. Im currently running Liquid Smooth (with ART enableD) and have not had any issues. I am streaming from my Google Music and bluetooth is connected to watch and my car. Cutting out and stutters are gone.
So may be ROM specific?
Small update; connected to a a Pioneer AVH- 200BT and the watch with no issues.
I'm having the same problem. My Moto 360 is constantly connected to my stock Moto x (original). When I stream audio over bluetooth from my phone to my car radio, the phone and radio randomly lose their connection to each other. Sometimes they appear to be paired and my phone says that it's playing, but no audio is coming out of the radio, so I have to cycle the phone's bluetooth off & on again to get audio working again.
Edit: I just found a thread on Motorola's official forum for the 360. Matt, the forums manager, thinks that the bluetooth capacity of the phone is being overloaded.
No issues with my note 2 connected to watch and my Hyundai car audio

After some more testing I still have the same issue, Works perfect with watch disconnected. There isn't some kind of widget or toggle that can discount/reconnect only the watch is there? without going to the wear app.
But I did find this, it has something with the music controls on the watch. I was uninstalling Spotify and reinstalling it. Before the watch was synced knowing I have the spotify app, I was able to use the app and play perfect audio. Of course this doesn't last long before the watch kicks in. After doing more re-search we CANT disable the controls on the watch no matter what. Least with the current version we are on, Hopefully that will change.
Is anyone else able to stream movies from this phone to their DLNA devices (my case I use either Panasonic smart TV or Xbox One to stream to)? I've tried AllConnect and BubbleUPnP (and lesser know ones from google play) and they all drop connection between 5 - 15 minutes into the stream. I've tried turning off battery optimisation on the apps but it made no difference, nor did a reset. On occasion the phone even soft reboots whilst streaming.
Never had this problem on my android tablet or other phones. Any ideas?
I'm on the latest stock android nougat, unrooted. Never got to see if it worked on MM.
Hi guys, could anyone help me out with this?
Had a bit of a breakthrough with it today... the phone streams video perfectly without cutting off after 5/10mins if I set the phone to 'stay awake while charging' in developer options and leave it plugged in. I assume by activating that setting there are processes being overridden and prevented from occurring that cut the video stream off in normal use.
Perhaps some system process related to doze/battery optimization?
