Bluetooth no media audio sound AAC, SBC codec -Redmi Note 5 Global 9.5.6.0 & 9.5.13.0
Redmi Note 5 Global 9.5.6.0 & 9.5.13.0 ROMS:
The media player plays the song, but there is no audio sound when I connect via Bluetooth the Redmi Note 5 phone to my Kenwood KMM-BT304 car headunit (Kenwood 2018 modell year, supoorts AAC and SBC codecs).
The car radio works fine with Redmi Note 5A, Samsung Galaxy S7, etc.
At the developer options AAC is the default codec.
If I manually change it to SBC, then works perfect.
But at the next time, when I connect to the car radio, there will be no media audio sound again... I have to set manually the SBC codec.
Is there any media patch what fixs this problem?
I have the same issue where no sound comes through my bluetooth headset on my RN5P Global 4/64, running AOSP Extended v5.5 Oreo 8.1.0, hope there is a fix for this soon Also haven't tried changing the audio codec, will try now

Seems changing the codec etc doesn't help for me

Samsung Galaxy S7 Edge -Android 7.1 - bluetooth media audio works fine
Redmi Note 5A - Android 7.1 (MIUI 9.5.9.0) - bluetooth media audio works fine
Redmi Note 5 Global with Andorid 7.1 based ROM (MIUI 9.2.13.0) - bluetooth media audio works fine
Redmi Note 5 Global with Andorid 8.1 based ROMs (MIUI 9.5.6.0 & 9.5.13.0) - no media audio
Unfortunately in the Nougat based ROMS gives no information about the used codecs, in the developer options.
At the 8.1 based 9.5.13.0 ROM the media audios works temporary (until next BT connection restart) if I "Disable optional codes" (Developoer options / Bluetooth audio codec).

The Bluetooth media audio problem still present in the new 8.6.14. MIUI10 ROM.
added screenshot from MIUI 10 global beta
MIUI 10 global beta exposes all codecs under Developer options.
I am, however, unable to set my streaming codec to AAC when using allegedly AAC-supporting bluetooth headphones: https://www.soundcore.com/products/variant/spirit-x/A3451011
I can change the setting to AAC but it automatically switches to SBC 48 KHz when I start playing music. I'd need to check with other headphones to see if it's Xiaomi or Anker that's bamboozling me.

I found this on a forum about changing the priority use of bluetooth audio codec, and ik comes close to what I am looking for:
Devices running Android 8.0 that support A2DP automatically gain the additional codec support. Device manufacturers may need to obtain separate licenses and binary blobs for some proprietary audio codecs. In addition to SBC, Android 8.0 supports the following codecs:
AAC
aptX
aptX HD
LDAC
Device manufacturers can choose which codecs their devices attempt to use first. Set the codec priorities by changing the following values in the file res/values/config.xml:
<!-- Configuring priorities of A2DP source codecs. Larger value means
higher priority. Value -1 means the codec is disabled.
Value 0 is reserved and should not be used here. Enabled codecs
should have priorities in the interval [1, 999999], and each
priority value should be unique. -->
<integer name="a2dp_source_codec_priority_sbc">1001</integer>
<integer name="a2dp_source_codec_priority_aac">2001</integer>
<integer name="a2dp_source_codec_priority_aptx">3001</integer>
<integer name="a2dp_source_codec_priority_aptx_hd">4001</integer>
<integer name="a2dp_source_codec_priority_ldac">5001</integer>
However, I could not apply this option since I was unable to find the file having these settings.
Therefore I hope someone here on the forum can help me finding the solution

On my RN5 Pro with 9.5.13.0 rom am able to play music and calls on my Harman car infotainment without any problems.
I'm running into the same problem with a Kenwood DPX303 unit. Track information comes through, but no audio. Global model, firmware v9.5.17.0.
Same problem here on a Kenwood dpx 7000DAB.
Other phones zich as Motorola no problem.
Redmi note 5 global.
Maybe sismilar problem, bluetooth audio stuttering with my embedded Golf VII Bluetooth audio sound system.
I reported the bug on the MI website, you can confirm it if you have the same problem.
http://en.miui.com/thread-3230620-1-1.html
Tom.
I have no problem with various of Bluetooth headset, headphone, earphone and speaker. All play the sound properly and use SBC codec by default. It seems this is bug from Oreo itself. I remember someone ask the similar things in Automagic forum, and I just realize it now. I have flash RR 6.1. But the codec also reseted to default when we exit the developer option, same as in MIUI.
It seems there is no viable solution currently. I would use workaround if I encounter this problem. You will need automation app, which detect bluetooth connected event to certain device. Launch the developer option and use accessibility to scroll and change that codec option back to sbc. I prooftest the concept in Automagic, but you can use tasker + autoinput or other Automation app which support accessibility to do it. But yeah, it is too hassle for most users here, as not everyone use automation app.
Yeah you're right. However in my case I already tried a lot a tricks like change codec and so on. But at the end of the day nothing works better...
I'm very disappointed...
On my 6.1 plus running android Pie, connecting my bluetooth headphones that supports AAC doesn't seem to work.
In the bluetooth device options, the HD Audio: AAC is shown and enabled after the initial pairing, but disappears after reconnecting.
In addition, the codec in use as shown in developer options shows SBC and refuses to change to AAC.
And poweramp also says it's using SBC.
I know my bluetooth headphones do support AAC because on another device, that was the codec in use.
Is anyone else having this issue?
Android 9 Pie

On my Moto X4 also have this same problem after upgrading to Android 9
I tried with my Nokia 6.1, it connects and keep the connection as AAC with a Sony XB40 and a Pioneer NEX5200, at every connection. However the Sony supports LDAC, and even if the ldac libraries are on the phone, it only uses AAC
Bluetooth on pie is 100% f**ked. Google broke it after the first beta release. It affects all devices, including their flagship pixel line.
Flash an 8.1 rom or get an iPhone. That's your options unfortunately.
After updating to Pie bluetooth audio turns useless because only for 10~30sec the audio is continous. after that short period harsh interruptions begin to happen until the audio stops. all this sequence in less than 1min.
my headset is JBL DUET Mini and work fine in other devices.. I verified this problem with spotify and YouTube.
I tried to change bluetooth audio setup in developer options but remains the same.
Anyone having the same issue? Any idea?
Thank you!
I've had the same issue in Oreo, and now in Pie. Though it's never gotten to the point where it stops; it just continues, horribly, 'til I stop it myself.
Tested with Vanilla Music, streaming via Bluetooth to an Amazon Echo, Echo Dot, and an Amazon Basics Bluetooth speaker. (jeez, never realised how much Amazon stuff I have lol)
Bluetooth is horribly broken on pie and its interferes with WiFi.
There is a new update for pie, can you check if it is still broken?
Poor playback to Anker portable bluetooth (4.0) speaker with crackling / stuttering noise interference when initiated from A2 Lite. Works fine from Laptop to Bluetooth speaker (A2 Lite disconnected), but v. poor from A2 Lite to speaker. NB. Same digital media.
Suspect Bluetooth problem with A2 Lite Pie 9.0 (OTA) version. V10.0.2.0.PDLMIFJ
Could be a CODEC issue?
Developer options show :
AVRCP 1.4 (Default)
Bluetooth audio codec streaming:SBC
audio sample rate: 44.1 khz
Audio bits per sample: 16 bits
Audio channel mode: Stereo
Playback quality: Best effort (adaptive bit rate)
updated: experiencing same issue when using Ausdom M04 Bluetooth headpones with A2 Lite

AAC codec was removed in PIe, leaving only the low quality/high latency SBC codec. Hopefully the next update includes AAC as it is absolute bare minimum for a 2018 phone of this caliber.

All codes were removed except that low quality low bandwidth sbc codec, it is reall low bandwidth broadcasting so you with have a lot of lag with Bluetooth, the aptx magisk module works but, you have to use Bluetooth headset for music, no loudspeaker or headphone jack will output music streams. I'm sure PIE is just a stable beta so hopefully the final version should qualcoms codec.
I also having this issue even already upgraded to:

Noticed a number of Bluetooth bugs logged with Google regarding Pie.
https://issuetracker.google.com/issues?q=bluetooth
Someone raised the A2 Lite issue, but it was rejected, saying it was up to xiaomi to sort.
https://issuetracker.google.com/issues/122369751
Just wondering if it could be a hardware issue, e.g. wifi and bluetooth using same frequency on same ariel and interrupting each other?
They (google) do seem to have assigned the SBC codec issue for investigation so that is positive.
https://issuetracker.google.com/issues/123179438
Had the same problem and went back to oreo.
Now everything works fine.
Ive repacked the aptx module in magisk, and bluetooth works loads better. i do get the odd jump where the equalizer switches on and off due to system optimizing, apart from that, all good. If anyone want to try heres link to the repack, with thanks to those who made the previous modules. https://1drv.ms/u/s!AqlJY73bUA7rholXS82XCuculBPhag . Use at own risk. Also, im not responsible for the link name lol.

You need magisk v18, goto modules and click the plus sign, navigate to where the module is located and click on module, magisk will install it. Im not sure if it will fix issue but i can tell you thats it performs better and less latency than sbc.

After installing january 5 update, the problem persist at the same way.
I have noticed in some situations that audio stay OK. For example, while at work, in my desktop using BT audio w/my headset, everything is ok. But if someone pass nearby my place, audio start working bad until the person went far enough. I think other devices BT affects audio, or antother type of EM signals, like WiFi, maybe...
I wish i could turn off "always visible" option in my device to test it. But that option is missed in PIE
I have the same problem
After update Samsung Galaxy S9+ to Pie, LDAC codec not working..When i try to play music on the phone or yotube the aplication not working..If i select SBC codec everything it's ok...i try this with my wife phone(S9+) and the same problem..the phone is pairing with a HiBy R3 player with support LDAC codec and it works before update the phone to Android Pie..please sugestion..thanks

This is the same issue I have described below "Bluetooth with SBC only?". It looks we have just to wait until/if they sort out the issue in a new Android patch.
Wanted to report that I'm having the same issue however it at least only drops down to aptX.
Posting here since I found this thread by googling and it doesn't have a clear answer.
They added an LDAC Toggle on the device page in bluetooth settings, you have to make sure that's toggled on, then your phone should negotiate an LDAC connection with your headphones (or in my case a Radsone EarStudio)
Hello everyone.
Since 2 months I know have this "strange" phenomenon that when I connect my Realme 6 Pro to my Bluetooth sound device of my choice, for the first few times connecting there are only popping/cracking noise sounds coming out. No music or anything relatable. After connecting around 5-10 times, it finally will play music (also it suddenly goes back to the cracking state when clicking around in youtube).
Bonus: most of the time (even if connected right and playing music) the microphone wont work in calls.
I cant fix this sh*t and it really bothers me a lot lately.
Hopefully someone can help, or else I´m going to throw this phone into the trash can... xD
Greetings.
My BT works fine for the most part, but sometimes it breaks up. I am really hoping it's just a software issue
Me too, for about 2 or 3 months now. Wasn't a problem before. Thinking I'll try factory reset soon, see if that fixes it.
Hey! I also have this problem and what i found is, if your Bluetooth audio support Aptx codec, it will enable option "Use High Quality Audio" in your audio bluetooth settings. Try to disable (it will use SBC Codec) and my problem disappear.
But, it really annoying. I already try my bluetooth audio with another phone and it worked fine with Aptx, so i know my bluetooth audio is not my problem. My workaround so far are disable high quality audio, then enable Aptx manually in developer options with AVCRP 1.6
Not sure if my device actually using SBC codec or Aptx after change it manually on developer options
Hi All! I solved problems with Bluetooth by switch off Dolby Atmos!
