[Q] Audio issues

HI all, just received my Note 2 today (thanks Amazon!!) but I'm having some issues with audio quality. I use Bluetooth to connect my phone to my car's head unit and stream via google music. Previously on my Evo 3d I was using an EQ app and let's just say that the 10" sub and 500w mono amp in my car made things shake and rumble rather well.
Now however with the Note 2, using the same setup I have almost no bass. I've tried a few EQ apps and all have the same issue. They will effect the mids and highs (and other sounds) but I can't get anything to make the bass pop really hard.
Any suggestions?

I know what you mean, I had a epic touch and could tune my car stereo via dsp manager. Now can't get dsp manager to even work. I did buy an eq app off the market and it works ok, not as good as dsp manager.

[Q] Does the amazon fire tv work with bluetooth headphones?

I want to know if its possible to pair some bluetooth headphones with the fire tv since it does have bluetooth? I would be nice to be able to watch a movie using bluetooth headphones with the unit. Only makes sense that this should be a feature.

Did you ever get this to work? If so, how did you do it? Roommates are complaining about my late night tv watching habits.

Yes if you install the Android Settings.apk you can make the FireTV pair with bluetooth audio devices. However with both devices I tried, a headset and a speaker, there's horrendous audio lag that makes it basically unusable. I guess I'll just wait for official support from Amazon.

Dang that sucks, this thing really needs a be update now because so far it's missing a lot of things.

Have you used the audio offset feature to correct the lag ? I had to use it to correct the lag while using my Ouya and a Bluetooth enabled powered PA speaker.

There's a good chance the next update will come June 18th when Amazon reveals their smartphone. I would expect the Fire TV will need to be updated in order to interact with the phone.

It's not a constant lag on the firetv, lag increases the longer you play something.

All you need to do is connect a USB Bluetooth receiver that often comes with the headphones and pair it with that directly. Get a multi-USB hub so you can connect various other things to it also. I'm using everything with the USB port like air mouses etc. and all work perfectly and it doesn't require any settings or rooting.

where to get a working settings.apk ?

I used settings.apk to pair my headphones. Music plays just fine. However playing an .mkv video thru XBMC-Kodi did not work at all. I just got really loud static -- I guess there was a problem with the dts audio. Knowing there was an audio lag anyway, I didn't mess with the XBMC setting to downmix.

Cross posting from the bigger thread...
I successfully paired my bluetooth headset using settings.apk method - thanks!
However - Bluetooth only puts audio out of my headset for SIDELOADED apps - but not apps from FireTV's app sources, i.e. NETFLIX. (I even confirmed by installing NETFLIX and sideloading NETFLIX - audio comes out differently ...)
Does anyone else experience this?

Why is Bluetooth working so well wire AFTV now? Not complaining, just wondering.

My old Note 2, want to turn it into a media device for my car

Hi all. I have a spare Note 2 that I would like to turn into a dedicated media player for my car. Meaning, I don't care about any other apps really, just Spotify and my media player on the device itself.
Technically there really isn't probably much of a reason to root the device that I know of. Admittedly, I don't know anything about rooting a device, so I don't know all the benefits.
Having said that, there is one problem I'm hoping rooting will allow me to bypass. When I turn my note 2 volume all the way up, the connect to my car, when a song begins to play, the volume will sound loud for about 1 second, then all of a sudden drops several DBs. This seems to happen on both of my Note phones, Note 2 and Note 4. I'm hoping that rooting my phone will allow me to bypass what ever is happening on the phone.
I started to go through the process of rooting, one of the first things the instructions say to do is to backup the phone. I followed this h t t p : / / beginnerguides.net/android/how-to-backup-every-mobile-device
However, after starting the process, the backup software said it was unable to connect to my phone. Which I'm not sure why, Windows 10 sees the phone just fine in Explorer.
If I don't care about anything that's on my phone, is there any real need to perform the backup??? Can I just skip this step and move onto rooting?

Did you try to just use another media player? like Shuffle+ for example.
For car use, I recommend AutoMate Car Dashboard app, is really cool :silly:

i've tried an iPhone and a Windows Surface. Neither of those devices had the volume issue.

Try another music app like Shuttle+.
If this doesn't fix your issue, root and install agni kernel with boeffla sound control.
With boeffla you can bypass the android audio compressor and reach whatever volume you want.
ps: the volume drop you listen, is just a protection, the track is just loud.

Not sure shuttle will be what I want. I use Spotify, so 90% of all the music I play is through their player.
I will look into agni and boeffla.
Will these work on my Samsung SGH-I317?

Ok suppose a better question is, If I install the AGNI kernel, will I still be able to run Spotify?

I supposed you connecting your devices via Bluetooth. It is possible your phones to recognize faulty your connection with car as Bluetooth headset and lowering the volume for protection for your ears. There is a setting "Limited Headphone Volume". You can disable this at some roms at settings or at media player settings.

I was reminded last night why I even bothered upgrading from my Note 2 to the Note 4… The headphone jack is messed up on it. So, at this point, it does not even matter at this point unless I get that fixed.
As I was digging around last night, I read here at XDA that the AT&T Note 4 is unrootable.

Bluetooth audio codec: does not stick

I keep on setting the audio bluetooth codec under dev optioons on "aptx" but after exiting the option goes back on "default".
Anyone can help?

Mine doesn't appear to stick either, but when I use my BT speaker I see an option in the connect dialog to use the Qualcomm aptX driver even though the codec is set to default (SBC). I don't see this aptX option when using my car or earbuds. I know this doesn't really help much, but I thought it was relative. I do know that the AVRCP setting does stick. Have you looked in the Google Issue Tracker? I'll go and star the issue if I can find it.
Edit: It is THERE listed as closed due to lack of data, feedback. Seems they ignored the obvious.... codec selection not sticking?

How do you tell if aptx is working while you're playing something to say a wireless speaker?

In BT settings I see a toggle for Qualcomm aptX and it's on... but in Dev Ops the BT codec still says Default: SBC. I think the audio codec setting there is busted, but the phone seems to use the best available codec. The device is a Creative (Soundblaster) Roar BT speaker. Now if I could only get the phone to auto connect to my car kit. Stays paired but will only manually connect which is a real pain.

Hmmm. My JBL Flip 4 is paired and it can use aptx but no option there. Weird.
My fm transmitter car kit will connect automatically, as long as it's set for media and phone calls.. Is yours just set for media only?

Yes, I've tried every combination there. It was working perfect with the N6P, and has never worked with the P2XL. Car kit is the absolute cheapest Chinese one you can find on Ebay... audio only, BT version 2.0 I think with no phone mic lol. Time to pony up and get a newer/better one. Had not considered FM transmitter because my car has the line in AUX. in my console so I can hide it.... It's about the size of a matchbox. This is a first world problem I know, but really annoying to me, and I know it's the phone because the Nexus was working for a year no problems. Thanks for your response.

We are both very frustrated here. Me cause I know I have an aptx capable device and am not getting to use it. You because you can't do a simple auto connect via bluetooth. Oy! Come on January update!

see my post here for a similar issue that I was able to workaround fairly easy
TLDR: You need root, edit your build.prop (using text editor, some app from the play store, etc) and change the following key: persist.vendor.bt.a2dp_offload_cap
by removing -aac from the string.
I'm sorry if it looks like I'm spamming I just encountered this issue on a lot of forums with no result and I do hope that this will help some

Bluetooth audio quality question

Hello. I change phones alot and have noticed that some phones(all android) have better bluetooth playback than others.
I had a oneplus 7 pro before this phone and the bluetooth quality to my truck was great and had no issues but with this phone the highs sounds scratchy or like if the speaker is bad. But if i connect it with a wire connection it sounds great. Everything with the 2 phones is the same. On both i was using the galaxy watch and pretty much the same apps. On a previous phone the note 8 i had the same issue but it was a different car. Seems like its the way samsung handles bluetooth.
Has anyone had this issue? If so was there a fix?
Thanks

What do you mean?

The only two things I think about is the codec used that may be different across devices, and the Bluetooth settings that sync the phones volume with the headset (the differences are noticeable).
Since no DAC is used in Bluetooth, I don't think it can comes from them, for a same headset.

On Samsung phones you should run the adapt sound process. Try this.

I tried with the sync volume off too and no improvement.
I looked for the adapt sound and my phone doesn't have that setting. Or is it something different?

It's in Sounds and Vibration 》 Advanced Sound settings 》Sound Quality and effects 》 Adapt sound
You have to do this in a quiet place and ensure to answer honestly. If you can't hear the beeping press no.
After doing this the sound quality is night and day difference.

Ok found it. Ill play with it a bit. Thanks

I've had issues sometimes with audio being piped through the "Calls" Bluetooth channel versus the "Audio" channel so worth checking as the quality is obviously night and day.
I also like enabling Dolby Atmos on my Note 10+ for music so worth playing with too. Additionally, I recently found Samsung's Sound Assistant app which let's you customize a bunch of sound settings so worth checking out as well:

Is there an easy way to tell if the audio is going through the call channel?

Easiest is probably just uncheck calls in your phones BT settings for your truck (and make sure audio is enabled). If the sound is still not great then this isn't the issue.

Sorry to respond to an old thread, but I was wondering if any of this fixed the OP's problem. I followed all the recommendations here and on other threads but have not been able to solve my recent Bluetooth audio problem. The sound has been terrible lately.

Same issue here on my s10+. When playing any audio in my car via BT i hear the distortion/hissing noise especially when the song has a higher treble frequency.
I have just about tried all fixes i could find on Google, and no luck.
When connecting to my ear buds (Jabra Elite 65t) it disappears and checked in developer mode that it supports to AAC for BT Codecs.
But when connecting to the car it reverts to SBC.
The issue clearly lies on Samsungs side, as my brother has a Huawei p30 Pro, also has bluetooth 5 and plays amazingly well in all aspects (Bass-Mids-Treble).
I know I'm posting this almost a year later, but i am desperately looking for a fix.
SN. I have recently updated my phone to Android 10, despite all the complaints to Samsung from many users... Sadly this issue has not being fixed on my side.
From what i see online, people have given up on Samsung and opted for Rooting their Samsungs and installing Viper4Andriod.
Has any one done this and can confirm that it fixed the issue?
