Try changing the SELINUX to permissive and check again.

Check and get the viseeo wma1000 it plugs to any 30 pin iPod integration cable. This works with very good sound quality for wireless streaming of music. It works with most cars.

Had the same issue drove me insane, go to performance profiles in francokernel manager, change setting to performance (Balanced and power saving cause the issue) any of the power saving settings can mess with Bluetooth.

No audio after sleep problem (Solved)

I just solved my Touchpad no sound problem and I am very excited. :victory:
First just a brief of my problem:
1) My touchpad is 32GB model
2) I have no audio problems in WebOS 3.0.5 ( So it is a sign of No HW problem, I guess)
3) Using latest Nightly build (cm-9-20130714-NIGHTLY-tenderloin), no audio from the speakers at all, it had audio on right headphone.
4) After old driver Wifi/Audio patch (update-ath6kl-v4.2-for-20120520-signed.zip), Speakers started to work until the tablet went to sleep mode. (Famous " No audio after Sleep " problem) But after resume, no audio and had to reboot the tablet to have audio back.
None of the other different methods and apps recommended by others like Headset Blocker app worked for my case.
Finally I used Wifi Keep Alive.
Just set it to keep the Wifi always on and choose the option Advanced-> Enable Workaround 2. which I makes a partial wakelock for Wifi.
So Wifi and Audio wont go shutdown during sleep.
Now Audio from speakers goes down during sleep and comes back again after device wakes up again
Seems to have fixed my sons Touchpad problems. Thanks brother, you are awesome! :laugh:
Update: This worked at first, but for whatever reason the issue has returned on my device. Thanks anyway.
Unfortunately the method I mentioned previously did not work properly and sound disconnects when tablet goes to sleep.
But good news is now I am using [ROM] [4.4.4] [CyanogenMod 11 by Jcsullins] [DM] [10/15/14] and I can confirm that using this ROM with no modification, sounds comes back to the speaker after touchpad wakes up from sleep. When headphones get connected sound is mono and after disconnecting them, touchpad has no sound at speaker and has to be restarted.

Earpiece and Speakerphone super low after using bluetooth handsfree.

Hi everybody. I have the t mobile moto x 32gb on ATT. Works great ..the best phone no questions. I have an older car with aftermarket JVC unit with bluetooth capabilities inluding A2DP(which works great by the way) but the microphone of the JVC is not good so I don't use it for phone calls. I had that issue before where after the phone being connected to the car and disconnected (when I leave the car) the sound is super low it shows max but it is not(the moto x has great crisp and loud sound both on the earpiece and the speaker), so I have to restart the phone and this will fix my issue..but since I am not using it much I was ok with it...Now I have a 2010 Prius with blueetooth handsfree calling but no A2DP(that is ok with me I can use the AUX). The microphone on the Prius is great people are saying they hear me great and so do I. But now I am facing that issue again..
Is anyone familiar with that ? It is really annoying that I leave the car where I was in a conversation with great sound I lock my car and walk on a busy street and cant here what people are saying no matter if I am using the speakerphone or the earpiece..I have to tell them that will call them back in a minute after I restart my phone.
PLEASE HELP !
THANKS
Anything ?
Try persist+ from play?
Bluetooth volumes have been haunted ever since 4.4. Hell... plugging in the charger when I am on my vehicle's bluetooth changes the volume.
Hoping this finally get this fixed in 4.4.3, but until then, I have found a number of tricks.
1.) There is a sweet spot on the volume scale (around 70%) that is best to leave it at.
2.) I haven't had to restart my phone... usually just cycling BT off and on again restores original volume. Sometimes even starting/stopping media playback fixes it.
I can confirm to have the same problem. Hope it'll be solved in next updates.

What Could Cause Bluetooth Audio Stutter? [6.0.1]

Hey everyone,
I've been battling this issue since Day 1, and its been a bumpy road. It seems as though this is a widespread issue across many Android devices, and fixes range but none of them seem to completely eliminate it.
When connected to Bluetooth audio, certain devices, the audio stutters or "skips". Ive noticed this extensively in KItKat. One fix for rooted devices was to increase the idle CPU frequency, I did so with Tasker and it definitely suppressed the stuttering, but did not completely eliminate it.
One of the most notable points of stuttering is when you answer a call via Bluetooth, then hang up. After hanging up, and music resuming, there is a solid ~10-20 seconds of constant stuttering and skipping until playback returns to normal.
Imagine my surprise when I upgraded to 6.0.1, and had absolutely no stuttering without increase CPU frequency or anything! Just buttery-smooth playback, all the way through, even after hanging up a call.
However, a couple of weeks after, the issue came back again. I had to re-enable my task to increase idle CPU frequency, and that horrible stutter after hanging up a call is back, strong as ever. To me this indicates perhaps something I modified after stock interfered., however nothing I can think of should come close to affecting it, other than XPOSED (however, XPOSED was installed prior to this issue coming back up, and no new modules were added)
Additionally, since Marshmallow, my phone won't reconnect automatically to my head unit. For example, when my car is on accessory mode and the stereo is on and BT connected. When I start the car, the system momentarily turns off for ~5 seconds at most, and turns back on. With Lollipop it would automatically reconnect, here is causes some serious problems as the only way to get them to reconnect after is to turn off the stereo and the phone, and turn both back on again. Sometimes I even have to do a couple of cycles.
Does anyone have any ideas?
i tried to do everything possible to fix the issue... I have a stuttering keyboard as well... anykeyboard I use seems to stutter, it lags a little, but most words that i type apear two times...
I have no issues at all like that, or stuttering throughout the system. It is specifically related to Bluetooth audio.
Anyone?
I've always thought kernel

If you do not have this problem, what kernel do you use? I just flashed BeastMode today, hoping that will bring me a bit of luck. However as it worked initially and a few weeks later broke down into the pathetic mess once again, I have my doubts
I use power amp and in advance I set thread priority to the highest and audio buffer to 750ms. I've used them all and haven't had skipping

Seems to have improved it, but reconnect issue is still present
The reconnect issue may be related to the stuttering.
The unit may be also trying to download contacts at the same time which causes the stutter.
Have you tried unpairing it from the unit, renaming your phone and then pairing it again?

I have in fact tried to re-pair the unit many times, to no avail. Factory resets also yield no benefits. It is set to auto download contacts, I'll try to disable that option to see if it improves anything.
I have the stuttering almost removed, however it still sometimes occurs. On a recent long-distance road trip, it randomly started stuttering after playing flawlessly for 1.5 hours, it was incredibly frustrating. I rebooted the phone, and the stereo, reconnected and it started playing smoothly again. Keep in mind however this is with both raising idle CPU frequency, and changing the poweramp options mentioned in Post #7
Perhaps I should try a custom ROM?
You can also try stopping media scanning. I think there is a xposed plugin
I only notice this on a non-name-brand headset. (Also, after it happens, I disconnect and reconnect...and it works fine from there on out...until Power down) My other 3 don't have this problem. Music plays, get a call, hang up, music pick right up. Didn't read your post in detail to see if you've tried a different pair of BT receiver.
FWIW it's not just you, also use PowerAmp, have the buffer turned up, and also get stuttering. On pvsgh's stock rooted deodex'd debloated 5.1.1 with beast mode 1.92 + ZL fix and both my motorola s10 headset and sharkk speaker stutter from time to time. It does not seem to be universal. In the beast mode thread it bluetooth audio issue was brought up, but didn't really get much attention ::shrugs, palms up:: I even limited them to media only but still get the stuttering.
Like so many things it seems, it worked ok before the MM update (910t3 on dok2 ootb) and now doesn't. Kinda like my ability to sign into enterprise level (work - EAP login) routers...
CM12.1 didn't make a difference in my case. Been on several stockish 5.1.1 roms as well. It still happens. Swapping out roms doesn't appear to pay off. It hasn't for me anyway :-/
Interested to see if a solution (or a cause?) lands here...

Headphones volume is extremely low

I have a big problem with the Mi A2 - it's really quiet using headphones (through the stock adapter). It's not headphones problem. Now, the question is, is that because of the software or maybe because of the crappy adapter? I need the people from EU country to speak here because maybe it us because of the stupid EU law.
Noticed this too. You get a slight improvement with viperfx and master gain /xloud , but that's all I found out.
Now, even if I am a pretty solid fan of Jack + high end headphones, we are in 2018, moving to BT headphones with Bt 5.0 is the way to go. On this matter. Having aptx advertised and not able to use it without build.prop tweak is a more serious matter IMHO ??
Still Loving my mia2 everyday more tho. This thing is getting faster everyday and having the governor set to ondemand + touch boost disabled make it fast as hell and crazy battery performance (getting solid 5-6 hours SOT)
Grüß,
H
Same problem.... headphones were pretty loud on my old Mi4... now its really low. :/
What do you mean with "touch list disabled"?
Thanks!

I love my Mi A2 too but I swear I can't listen to the music because the volume is so damn low. While you are rooted, could you send this file - system/etc/mixer_paths_tasha.xml and this system/etc/mixer_paths.xml? I am sure low volume can be fixed by editing these files.
They can be stored in this place too - vendor/etc

Where is this option?
Solution?
This problem is something I struggle with too. Might it be the usb type c adapter to aux which is the problem? Can anyone try with a different adapter and report back? I am using Xiaomi mi in ear pro headphones. I need to use max volume to have a volume which I consider medium.

I just got my Mi A2 and the audio volume seems very low when Bluetooth paired to my cars stereo. Maybe halve the volume of my old LG phone. Very weird since the audio volume thru the Mi A2's built-in speaker is VERY loud.
Stock dongle's output is slow. Get some other 3rd party and sound will get louder. I have bought and its sound is quite louder than stock's one.

I just got google's newest dongle, it is good. The volume, while not overwhelming, is certainly loud enough with music. Dynamic Range seems quite improved also. I figured for 12 bucks, not much to lose. But turned out improvement for sure.
Mi A2 audio quality
I am currently using the stock dongle and mi piston fresh earphone on my Mi A2 for music. The audio quality is really poor. There's noise and audio is muddy. Is anyone experiencing this and is there a way to improve the audio quality?
I used the headphones of the leeco le Max 2 type c and it sounds wonderful ... but when using the adapter for my headphones Xiaomi sounds very slowly

This doesn't help at all. You'll still end up being stuck with SBC or AAC codec.
I recently converted my phone to Mi 6x and flashed AospExtended v5.8 Rom. Now LDAC is working perfectly with my sony wh1000xm2 headphones and volume output from stock dongle has increased to normal levels. So finally I'm able to use my MI A2 for listening music and I don't need to carry my old Moto X play with me just to use spotify.
I don't think problem is low quality of stock dongle. After all it is just simple adapter and it shouldn't have any or very little difference on audio quality (audiophiles may have different opinions). And I also had very low volume via bluetooth on stock rom.
I'd really love to use the stock rom because the stock camera is much better for day to day use than these buggy gcam ports, but low audio output makes it impossible. Mi a2 is great phone with ****ty firmware and I don't have any high hopes for Xiaomi to fix these bugs. Maybe in the future when development really kicks in we got rom wich is capable for music and photos.

So can someone confirm if this is a problem in the type-c to 3.5mm adapter? If i buy a usb-c earphone or a third party adapter the audio will be loud?
I'm really waiting for someone at XDA to comment on :

Heads up to Bluetooth audio volume decrease after first few seconds of song

Found a solution to something that was driving me crazy so I thought it may be helpful to share.
If you use bluetooth headphones/speakers like me and a song starts loud and clear but volume decreases after first few seconds you need to reattach the dongle with regular wired earphones and turn the "Enable Audio Tuner" option off.
When I first got the phone I tried regular earphones with the dongle and played around with the equalizer under "Audio Tuner". But I left that option ON before I took the earphones off. When you use bluetooth that option is greyed out so you cannot toggle. After trying a bunch of earphones and reading articles and trying to find hidden audio settings thinking "audio normalization" may be the culprit, I saw that even though greyed out, the slider was left on ON and I couldnt turn it on because I was on bluetooth.
So if it saves you several hours I'm happy to serve. Just keep it OFF if you are using bluetooth... :good:

You know what's odd, tho (coming from a mate 10 pro where that type of setting was COMPLETELY off limits if not wired): i could use it whether wired or wirelessly, but little did i know Ms. Update would along come and with her the fun gone.
It is now (9.0.11) possible to toggle the Audio Tuner while on bluetooth, however i made a suggestion to take out dynamic normalization (the thing that is lowering the volume when the song gets loud) from the Audio Tuner and make it toggleable separately.
You can like this thread so it maybe will be spotted by OnePlus team.
