Stuttering/Cracky MP3 playback. All other media plays well. - Nexus 7 (2013) Q&A

Hello all. I searched up and down the forum (and google). No one has the same issue.
Current setup:
Nexus 7 (2013)
Resurrection Remix v.6.0.0 (RR-O-v6.0.0-20180210-flo-Unofficial)
Elementalx N7 7.00 (all stock settings just turned on otg+charge)
Running through OTG --> USB hub and DAC in car
Issue: MP3's stutter, lag, crackle and pop during playback.
So far:
Tried Several music player apps (blacplayer, mediamonkey, musicolet, VLC, Kodi etc.
Tried 8+ different ROMS, same issue.
In VLC tried increasing the buffer, turning on/off all hardware acceleration settings. Same
Blue Ray rip .MP4 files play perfectly
YouTube plays perfectly
Spotify audio plays perfectly
Any experiences?

If you tried that many ROMS and players then the problem is with the DAC, unlikely, or the mp3s themselves. I'm also assuming you didn't have the same kernel installed on each ROM.

I did try a few older versions of elementalx. Do you think a DAC would have problems with a specific format? .MP4 files work, YouTube, and Spotify work well also. I will try connecting it directly to the amp without the DAC. Just wondering if it was software related. I can't fit it inside the dash attached to the headphone jack, which is why the DAC is necessary.
thanks for the response.

Unlikely the DAC since it's taking straight digital signals and doing it's own conversion. I'm leaning more toward the tablet not liking the mp3 decoding.
I haven't used a mp3 in many years so I don't know how the Nexus 7 actually responds to them. The fact that it handles mp4s okay also makes me lean that way.

fr4nk1yn, any hints as to something that would do decoding perhaps some software package? Those same MP3 files run great on my PC, Nexus 6P, Galaxy note 3 and plex. I'll try going directly to the headphone jack. Kind of a silly problem

music playback issues

I love the phone (got it launch day) puts my Mytouch 3G to shame. I love everything about this phone....... well except for one thing.
I am having a hell of a time with audio playback. 60% of the time i try to play back music on stock music player it tells me that the audio format is not supported on this device. using Winamp wasnt much of a help as it will just cycle through songs and freeze up.
resetting the phone helps sometimes but not everytime.
I also tried removing all the music from my phone and re-copying all the files. still an issue.
I've also noticed it acts up a lot more via bluetooth (i have a pair of rocketdog behind the ear headphones)
I'm stumped...
Any ideas? Anyone else getting this issue?
codec, song encoding comes to mind
also try with different amount of songs
i know on the old SGS if you had more than few hundreds of mp3 or mix format songs in it, it can drive it crazy
so try a couple hundreds, then work your way up, until you find the amount of files it can read before it becomes too much.
all this can be fixed once rooted, and installing better media players
winamp for android sucks by the way
you should try the ICE cream leaked media player from stock android, it's better
Curious why not just stream the music from ur pc?? google music is practically flawless
Seen a user in another thread had to format their card in this phone, then add music. Try that.

I tried this last night. didn't help much. I'm 99.98% sure it has something to do with my bluetooth headphones. Going to buy a new pair and see if it makes a difference...

If you get the sony ericsson mw600, you'll be amazed at their features. I love them and use them all the time and the battery lasts longer than the specs say. I can get 14hrs out of them.
Just picked up a new set of headphones.... does the exact same thing.... odd.... wondering if its just my phone or if this is a glitch...haven't seen anyone else report this.
Pandora and google music work great with my motorola s10-hd headset...

I'll be getting my phone tues. I use sony dr-bt22 bluetooth headphones.... will report back.
I have this problem when steaming music over A2DP through stock Music app or Google Music. All 320kbps fixed rate MP3s. I've tried via my integrated car audio, computer, headphones... all same result when playing local media. Streaming via Rdio works completely fine. Playing local media without A2DP also works fine... Logcat reports some kind of permission related problem...
Weird, I play FLAC or 320s all day long on this thing and no "Format Unsupported" has come up on regular headset/aux cable or BT. I have however, had a problem with the music stopping when I get a notification..the time continues to move but no sound.
Just an update, my stereo BT headphones work fine

Music/audio playback quality - stock phone

There have been a few threads about static, clicks, pops, etc... but nothing that really helped me figure out if i'm having a problem or not.
I have a stock GS3, purchased relatively early - 7/2 - from best buy.
I'm not happy with the audio playback quality, specifically when compared to other devices, like my iPod or old iPhone 4 that i had before this.
Either using the stock Samsung app, or using PowerAmp, which I've purchased... with all file formats... mostly FLAC, but also m4a, mp3...
Using any of the headphones i've tried... beyer dt1350, ety hf2, apple in-ear, etc... (not junk)...
The sound quality of music playback just doesn't seem "clear" to me... not any really blatantly loud static or distortion, although sometimes it is worse than others... occasional clicks, pops, etc. But mostly, just a lack of clarity... which could possibly be a constant mild static or distortion on the output.
Is anyone else experiencing it this way? Am i just being to sensitive to a different sound signature of this device vs apple's devices? I don't think so.
I'm 100% comfortable with the quality and integrity of my music files... i have a ton of them, and they play back fine on all of my other devices.
What else could it be, before i have to send it back to samsung and be w/o a phone for a week? best buy already won't exchange it for me, as i'm beyond my 30 day window.
help!
I know exactly what you mean, I'm very particular about my sound signature as well. I find using an equalizer to work wonders. But i have noticed that some equalizers dont work at all will the stock rom when listening to on device music with Google Play Music.
Have you tried using an equalizer or even installing Awesome Beats?
This is a development forum for custom OS and software... If you're completely stock, maybe you should take that up with Samsung or try some of the nice modded software...

[Q] HDMI experience - audio out problem

I have been playing with HDMI out. Using official Samsung adapter EPL3FHU and TV Panasonic TH-42PX80E. So far I cannot get out audio consistently.
When connected first time, I had system sound off, so I could see picture, but no audio (form system) as expected. When playing movie with BSPlayer, VLC, or MX I got audio out of built-in speaker though (and not through TV).
Reconnected with system sound on, I could get system plonks and boings out of TV. Playing songs from Neutron was fine as well. Even playing original Samsung demo video via VLC produced sound on TV.
Then I tried one .mkv with DTS (which plays fine in BSPlayer with sound on internal speaker) and the sound through HDMI stopped working. Then I tried again Neutron, VLC, but I could not get even the apps that were working, working them again. System sounds are fine though.
And so far I was not able to recover.
It looks like there are some incompatibilities, probably between some players, sound formats which break one part of sound path (but not all, as system clicks are still transported correctly). And this break seems to be kind of permanent, until some reset. But simple reboot does not solve this.
I wonder what I might be missing.
I can partially reply to myself. The problem is that some players (it seems BSPlayer, and MX do that) cannot play DTS through HDMI (though BSPlayer can play it through internal speaker) and for some reason it resets volume settings for multimedia to zero (i.e. no sound). Once I realized that and "reenabled" volume for multimedia, it seems fine for Neutron, VLC and system sounds.
VLC can even play DTS through HDMI out, but for some reasons suffers from sound being out of sync with video.
So now the question remains, what is good video player, which can get out DTS through HDMI out.
Have you been able to get multichannel audio out HDMI?

[Q] Audio Sputtering and Popping on Spotify, TuneIn

Hello all,
I love the audio quality on CM, however ever since using it on my Verizon Galaxy Nexus, the audio on Spotify has constantly popped and stuttered and sputtered and whatever other word you want to use when playing through the headphone jack.
I feel like I've tried everything outside of switching ROMs. Tiny Kernel, Franco Kernel, CPU Governors, etc etc etc, doesn't matter.
I've also done search after search after search, and I feel like I'm completely alone in having this issue. I can't find anyone asking about this anymore, now that Spotify claims to have fixed it in an app release months ago (which makes me think it isn't necessarily Spotify's fault, but who knows).
I should mention that this does not happen with Pandora or Songza, for instance. Only Spotify and TuneIn.
Of course, it doesn't seem to be a coincidence that both Pandora and Songza process the audio in some different way from Spotify and TuneIn, since normal use of CM's DSP Manager has no effect on those apps but does work on Spotify.
So, is there anyone else out there who has this issue with CM (or other ROMs)?? At this point I'm just hoping there are others out there who have had this problem just so it isn't an "only my phone" issue -- because those ones have no hope of being fixed.
I have the same problem, running stock 4.2.2 on my Galaxy Nexus. I think it's a device problem, not an app/background process problem.
I don't use TuneIn so I can't speak to the quality of its streams, but I have used Rdio, Slacker, Pandora and Google Play Music and they all play flawlessly.
ONLY Spotify plays audios with occasional snaps, crackles and pops, like a bowl of Rice Krispies. Some songs will play without a blip, some with a few, some with many. The songs are not interrupted...just marred by this defect. And it's never the same way twice with the same song.
It happens whether the song is streaming, or playing locally.
My guess is that the Nexus has difficulty playing Ogg Vorbis files, which is the format for Spotify streams and downloads. As far as I know, the other services I mentioned stream in AAC or MP3. While the Nexus supports Ogg Vorbis, it appears it does not support it very well. I'm going to test this theory by transcoding one of my Apple Lossless audio files to Ogg and then uploading it to the Nexus. My hunch is that it will demonstrate the same issues.
I guess we should consider ourselves lucky; before Jelly Bean the Nexus suffered from more dramatic playback problems. Do a Google search on "Music Stutters when playing long files and screen off: Galaxy Nexus" and read through it. There are a couple of posts that deal specifically with Ogg playback.
I've decided to live with it. I've been hopping from music service to music service trying to find the right one, and I always come back to Spotify. As long as the issue doesn't become more severe, I think I can re-program my brain to tolerate it.

My theory was incorrect. I used XLD to transcode Boston's "Hitch A Ride" from Apple Lossless to Ogg Vorbis (VBR, quality 4.0), then put the file on my phone. I used Winamp to play the file and it played beautifully.
So I'm thinking there's something specific with Spotify's encoding that the Nexus doesn't like.
What's odd is that I have run Spotify on other mobile devices and have never had an issue. That's why I have trouble putting the blame on them.
OP, after checking many Google leads, posts, etc. I believe--for Spotify anyway--I have found a way to stop (or at least greatly reduce) the Rice Krispies.
If you have Google Play Music on your phone, make sure it's fully updated and then launch it.
Within Play Music, go to Settings, then select Equalizer.
Turn the equalizer on, select the Normal preset, and move the Bass Boost and 3D Effect sliders all the way to the left to turn them off...unless you like them on.
Back out of Google Play Music to the home screen, then launch Spotify.
Go to Settings within Spotify, choose Audio Effects and verify the Equalizer is OFF in that app.
Using this combination of settings/conditions, I have heard just a couple of pops over a string of a half-dozen songs. I'm keeping my fingers crossed that it lasts.
I'm guessing that having the Google Play Music equalizer on, some additional processing is taking place that alleviates whatever is causing the popping to occur.
Good luck!

Bluetooth Music Issues?

Anyone having any problems running aftermarket roms? I'm on Liquidsmooth and I am extremely dissapointed in the bluetooth quality. About to go back to stock or get rid of the tablet to just use my tab pro instead. IT doesn't skip or pause but it like, mutes for a second every 5 or so seconds. Its not consistent. But it happens soo much it gets me really angry. I'm on a fresh copy of LiquidSmooth. Haven't really done anything and nothing is running in the background that could be taking up all the system resources. I've even tried multiple music players even tho they all are horrible except PowerAmp which still doesn't have a tablet mode years after said feature was in the works.
You know of any fixes?
Googled Android Bluetooth Skip and seems its a very common problem among a few devices including the Note 4.... I don't have any issues with my Tab Pro, Just Tab S... This is bugging me because its main function is to play Music Via Bluetooth. Would prefer it through RCA/3.5mm but I don't have one
Had the same problem with my phone, solved it by adding the bluetooth device as a trusted device, so that when connected to bluetooth speaker the phone doesnt lock its self, done the same on my tab s and no problems streaming music using google music, as far as i can figure out its related to the kernel lowering the cpu speed when the screen locks, so you may be able to solve the prob using a kernel manager and increasing the idle speed, but personally i like the phone not locking when listening to music as i can access the player without unlocking, making it easier to put on a different album or song, hope this helps

Use to have similar issues with the stock player on another device.
Solved it with Playerpro.
Install from play then in the app open settings then go to Audio.
Select to install the dsp pack then make sure it's active.
You will see a new option 'Audio buffer' change this to large. See how you go.
Seems to me also like an audio buffering issue (I think PowerAmp has a larger one by default). You could try raising the minimum CPU frequency since this us often the cause for problems kind this.
On that note, don't forget that none TW based ROMs don't have support for the APT-X codec that provides vastly better audio quality over Bluetooth as long as your audio adapter/headphones/car audio supports it as well. Nothing to do with the issue at hand though.
Its not a buffering issue. Its an audio pause issue. Its extremely common with Note 4 and some others. I solved it by going to a TouchWiz OEM style rom. The AOSP roms seem to all do it. Adjusting buffering settings changes nothing. Its as if the bluetooth drivers aren't capable of handling the "power" of whats going on. The Music still plays during the pause.
So far TW Roms seem to be the best for Bluetooth Audio. I use it daily since the Tablet is the main front end to my car, with a Sony 610BT AppRemote Deck.
