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

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...
Does the Nokia 6.1 (with Pie) support HD bluetooth codecs? Did someone tried to pair with sony or others headphones and check if LDAC is working?
I'm not much of an audiophile myself. I've never tested any of these out, but here's what bluetooth codec selection looks like in developer options.

yeah but it seems it does not work, everytime you exit the option, it go back to default.
I tested a BT speaker Sony XB40 and a car stereo Pioneer NEX, and both have "HD Audio" in their bluetooth properties displaying "HD Audio: AAC". I cannot change it, I tried to change the codec in the dev option, but it does nothing.
I don't think the developer options are meant to be changed. I think they are there to show what the phone auto-selects when playing.
This screenshot is from another phone, while playing to an AptX device. I think it works the same way on Nokia.
Hi everyone!
When connect my phone to car radio pioneer mvh-s300bt via Bluetooth phone set automatically sbc codec. I have latest radio firmware, so AAC worked correctly on android 8.1. After update to 9.0 work only with SBC. When i try change it in developer options, setting are constantly return to SBC codec. I feel different between this codec and it is little annoying for my ears.
Please, help how can i fix it.
Of course, xiaomi developers doesn't read any notification from users, so i must do it on one's own.
Thanks for help.
No solution so far, afaik.
Facing the same problem, Mercedes 2019 and Volvo 2019 both default to SBC.
YouTube is out of sync when streaming via A2DP, video is lagging, audio working fine.
Stock MIUI 8.1 was even worse, playback was slow and distorted.
Hi,
after enabled Developer options, i tried to change the bluetooth audio codec from AAC to LDAC, but everytime i set, it will then reset upon back and return to the option.
currently using Jabra Elite Active 65t.
May i know why is it?

Thats because those headphones dont support that codec. I have the regular 65t. If the device doesn't support a certain codec it will just go back to one that it does support.
Test it by choosing the sbc codec and it should change to it and stick. You will even notice a short pause in the music while it changes codecs.
Does anybody know how to get the audio codecs to change from sbc to any other setting and have them stick?no matter what I do it reverts back to sbc.
The device say if you are using a bluetooth headset should support other codecs like aptx, LDAC etc.,
I use Sony XB series bluetooth headphone, the audio codec in developer options sticks to LDAC only if I choose the headphones connection for quality in the Sony app.....else by default it reverts to SBC.

It will revert to SBC when nothing is connected. It will switch as soon as you connect an audio device. When I connect my Bluedio Victory, it switches to APTX on it´s own. The same applies to my car (also APTX) and to Galaxy Buds+ which use the Samsung Scalable Codec.
There's a setting within Developer mode to switch which codec to use

I had 2 harmon kardon Onyx 3 Bluetooth speakers connected and no matter what I did it switched back to sbc tried every codec nothing stuck,I would change it and as soon as I brought up the section in developer options it was back to sbc.

It seems that the Harman/Kardon Onyx 3 does not support any other codec than SBC. The phone won´t let you change the codec and revert back to SBC if the speaker does not support it.
Well Thank you for that information I did not know that.
