Hello,
I just noticied that it seems that Mi Mix 2 doesn't support APTX HD, with my bluetooth headphone and his apps, when i switch to APTX HD, the music cuts every seconds... Whereas no issue when it's on SBC...
Just, WTF?! how it is possible that a supposed flagship don't even has APTX? no headphone jack and no APTX?! are they joking?
It's possible to add the APTX HD codec to our device?
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

Soundabout app: crash, doesn't start the app on MIUI 9.5.13.0
Mono-mono app: we would like to use stereo media audio sound (for example: listen stereo music via BT)

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.
Hi All,
I have been using the Open Camera app for my video recordings on the Mi A2 Lite so far pretty successfully..This App is really nice with all the options also getting me
nice 4K Footage with high Datarates...
Now I want to shoot some interviews where I need to have a wireless Audio interface, using either my Stereo Bluetooth Headset,
Bagotte Sport Kopfhörer Kabellos with Bluetooth V4.1 + EDR-Audio-Decodingtechnology with HD-Microphone with CVC6.0, so
see: https://amzn.to/2V8bAdg
which claims to have a HD Microphone and supports Apt-X Codecs...
But I can´t get it to work with Open Camera APP. I also tried using the External Microphone settings and have tested a few BlueTooth Audio routing apps..
but I could not get the Open Camera App to work with this headset....
But there is a video which shows, how to change the Bluetooth codecs in the Mi A2 Lite:
https://www.youtube.com/watch?v=zVK4UIHOEGE
And I can also change this in my phone....
But I am always stuck with the lower quality SBC 8 Khz sampling codec, especially, when using Audio calls in Skype or other Bluetooth Audio recorder
apps.
I only found one app, that works with the headset for video recording that was
Wireless Video Recorder App
https://play.google.com/store/apps/details?id=com.webmirchi.Wirelessvideorecorder
but there is the problem, that I can not switch it to 4K, although it shows the setting and
also the audio with the Bluetooth headset is only recording with 8 Khz sampling frequency with my headset, so the sound is
just very muffled and has no good audio....
So is there any solution to get the Open Camera App to work with Bluetooth headsets and also switching the codecs, so to get
a real good Wideband Audio codec with at least 16 Khz sampling frequency or better at least 44 or 48 Khz ?
Many thanks.
Regards, Stefan.
It seems from some other replies in another thread, that the MiA2-Lite has a bad Bluetooth implementation....
So I guess it is better then to just buy a wireless audio interface and put it into the Microphone-Headphone connector or go via USB to connect
an external Wireless microphone....
Does anybody know how to connect a USB microphone or an analog Audio interface via the USB connector and can it then be used together with Open Camera ??
Many thanks.
