Each time I reconnect my headphones they revert to LDAC. How can I force the AAC codec and have it also persistent? My phone is rooted.
thanks

I am new to BT audio, but I have come across something very strange. I have a new Motorola S9 BT headset and a Cingular 8525. I have been able to make and receive calls, pause and skip songs in Media Player 10, but I had an awful time trying to make stereo play on the headset. It delivers system beeps, alerts, and ActiveSync tones to the headset. After some hard-resets, and some troubleshooting, I found this combination does indeed deliver very nice sound quality (without the A2DPfix). The problem is that it doesn't send AAC (.m4a) songs to the BT headset. I realize that there is only limited support for AAC, (WMP doesn't recognize the META data from them) but it does play them thru the phone speaker.
Why would WMP play some formats thru the BT headset and others thru the speaker?
not sure but you can use tcpmp with aac plugin
To preface, on OxygenOS 5.0.x/Android 8.0 we were provided with additional bluetooth codecs and additional setup for bluetooth codec manipulation in Setup>Advanced and Setup>Dev Options. In OxygenOS 5.1.x/Android 8.1, the Setup>Advanced options were removed. I'm currently on 5.1.4 on my OP5.
That out of the way, I'm trying to validate if anyone else is experiencing an issue that I'm having. I have a set of Bose QC35 bluetooth headphones that support the AAC bluetooth codec, support of which was added to the OP5 with Oreo. In OxygenOS 5.0.x, I had no problems with it. In OxygenOS 5.1.x, it will only connect with AAC when first paired. If I turn off the headphones and turn them back on, when it reconnects, it defaults to SBC and will not switch back to AAC unless I unpair and repair the headphones.
Does anyone else have Bose QC35 headphones that can confirm this behavior? Or perhaps another set of headphones that support AAC? I've tested with a pair of headphones that support aptX and it keeps the codec, so it appears to be either an issue with AAC on OxygenOS 5.1.x, my headphones, my phone, or Android 8.1 in general. Any validation would be helpful. Thank you

Hi everyone,
As title says, i can't turn on AAC codec, when i turn it on its changing as soon as i quit Developers options. I'm using qcy qs2 earphones.
Any ideas how to fix it?
From the specs i found these earphones you're using only support SBC codec, so you can't use AAC with them.

Can i ask You for link? I found that these earphones support AAC
Could anyone with the phone double-check their bluetooth codec options?
Being Android 8.1.0, it should have LDAC ... and that is extremely important to me. But it's missing from my phone. I have tried installing JamesDSP through Magisk, and it works, however I do not see how to enable its LDAC so its running everything through SBC or whatever that low-quality sounding codec is called.
Thanks.

I also wondered if such audio drivers like LDAC enabling is similar to having 4K 265H codec built in to the chipset & not a question of software updates can enable.....
Hi everyone! I just bought the Sony 1000XM4 headphones. The headphones support SBC, AAC and LDAC. However, when I connect to my device (Max Pro M2), I can only use SBC. even though in the bluetooth settings for the headphones, the option HD Audio: AAC (No LDAC) is enabled.
I went to the developer options to set the Bluetooth codec to LDAC (Qualcomm aptX Adaptive Audio), but the setting does not stick.
I don't have the 'Connect to two devices simultaneously' option enabled and the priority is on Sound Quality instead of Connection Quality.
I have tried resetting the WiFi and bluetooth settings but still can't get it to work.
I tried connecting the headphones to the Sony XZs and it instantly gave the option to use LDAC and used it. This makes me wonder if this phone even supports LDAC, even though on the internet it says that it does. I can't even use AAC, I am stuck on SBC.
Does anyone have any idea? Please?

I'm on Havoc 3.11, I don't know about stock ROM.
Yeah, couldn't get it to work on the stock ROM. Now, I'm on Resurrection Remix and it works!
