Is EVS (Enhanced Voice Services) supported for Oneplus 7t?
During a VoLTE-VoLTE call in the same network I never get EVS as codec, just AMR_WB.
bump
Its because Oneplus and other OEM never added the encoder or decoder to the software. Apparently patent trolls is the issue.

Hey Folks,
Can any one help me figure out How to enable AptX Codecs on my OnePlus 7 (GM1900 running OOS 10.3.3.GM57AA)?
I tried many times in Developer settings, but they get reverted the next moment always. Any workaround???
I bought a pair of Earbuds but cannot enjoy this feature. Any help is appreciated. Thanks in advance.

They are auto tuned if your hardwares(earbuds) are not supporting AptX codec then it always uses default codec you can't do anything about it...
At least not in Oxygen Os
Soundpeats Trueair earbuds are equipped with QCC3020 which is capable of AptX codecs. It must be a bug in OOS. I tried to force use AptX codecs in Developer settings but only to fail.

Maybe you are right
have you tried the magisk modules to enable aptx and other codecs?

for me only AAC codec worked because my earbuds only supports AAC codec you can see in the screenshot my earbuds is AAC enabled,check yours also if it is AptX enabled after connecting to phone or not. i thought that you want to switch to AptX codec to remove latency issues...or may be i am wrong ?

I do not get this extra option in ear buds settings.
But I got the AptX enable menu when I connected the same buds with a Oppo Reno device. So it's a Op7 device OS issue. I have taken the issue up to the OOS Team in OP forums. They have taken logcats and said they are working on this issue. Hope to get it solved.
Hi. I use Bluetooth airbuds. recently i found in the developer option that i can change the following settings:
1. Disable Audio A2DP ( OPTIONS ARE: enable/ disable)
2. Bluetooth audio Codec (OPTIONS ARE: SBC/AAC/Qualcomm aptX HD/ Qualcomm aptX HD Adaptive Audio/ Qualcomm aptX TWS+ audio/ LHDC_V3/LHDC_V2/LHDC_V1)
3. Bluetooth audio SAMPLE rate (POTIONS ARE: 44.1kHz/48kHz/88.2kHz/96.0kHz)
4. Bluetooth audio Bits per sample (POTIONS ARE: 16/24/32 bits/sample)
5. Bluetooth Audio Channel mode (MONO/ STEREO)
6. Bluetooth Audio LDAC Codec ( 990kbps/660kbps/330kbps)
7. Bluetooth Audio LHDC ( 256Kbps/ 400kbps/ 500kbps/ 900kbps)
i want to change the settings but it doesnt. when i change the settings it changes but when i close the settings it returns to the default settings. now how to change it and make it working ? thank you for your help.
no one knows about this ? really ? :/
Same issue here
I think only supported setting for both bt tws and phone that can be applied, i've use dual codex tws (kz z1) that use ACC and sbc codec, with both codec only supported 44.1 khz sample rate and 16bits per sample.
When i select AAC/sbc then i close the setting and check it again, the codec is same at last time i selected, but when i select aptx the codec setting is revert back to AAC/SBC again.
1 year late. that cannot be changed. It depends on the compatibility of your phone and the headset.
Use (checker a2dp) apk from Google Play store. Use this link, https://play.google.com/store/apps/details?id=com.widget7.check.a2dp&hl=en ...
it worked for me, using it for years i have redmi k20 pro and used the same software in OnePlus too....
For bit per sample and audio sample rate, we can directly Change it under bluetooth codecs in
developer option as per the music file we are going to play
Does P11 and P11 PRO support a variety of Bluetooth codecs?
I tested it. It is only connected to SBC & LDAC. The devices I tested were three Sony XF-1000XM3 & WH-100XM4 & Bose qc Earbuds.
All SBC and LDAC are connected only.(I don't think they support AAC and APT-X)
LDAC is Sony's proprietary codec so if you connect those that's what will get chosen by default. In fact others have tried on a Pixel 4 to get other codecs selected by Sony headphones to no avail.

I use my WH-1000 XM4 and Pixel 3A in dual device mode and it now selects AAC by default with my phone, when I first got the headphones I'm sure I read in documents that dual device mode was limited to SBC (ie disables LDAC) but maybe a FW update improved things.
I have a P7P, Galaxy Watch 4 and Sony WF-1000XM4 LDAC iem. I'm noticing a LOT of stutter when I set the Codec Playback Quality to "Optimized for Audio Quality (990kbps/909kbps)".
The stuttering goes away and sound is perfect when I place the GW4 in sleep mode. This seems to only be an issue with Pixel 6 and up - has there been some low level change to bluetooth hardware/stack since Pixel 6? Is this a bandwidth issue?
This isn't an issue with other Android 13 phones from what I am hearing - this is close to a deal breaker for me unless there is some workaround/fix. Has anybody else noticed it? Would a custom kernel help?

This is due to how LDAC works, it steals bandwidth from the BT data streams to carry that bitrate. It may be an issue with other devices, or other devices may have some QoS or something to that effect on the bluetooth side of things to prioritize the audio streams over data.
You could try a custom kernel in case it is some frequency capping or something on the device causing the issue.

It doesn't seem to be an issue on earlier Pixels or other phones, just PIxel 6 and up. I'm not very familiar with the available custom kernels for P7P, reading up on them now.
Anybody have any suggestions on a stable kernel that could potentially address a possible frequency cap?
I solved this problem by turning off Ultra-Wideband (UWB) under connection preferences.
I presume bluetooth scanning is a part of this function, and makes sense if while scanning momentarily the available bandwidth is reduced.
This is not solving your problem but I play exclusively FLAC both 16 and 24 bit, have developer options switched on as well and have zero stutter or any other problems (that I've noticed). Strange that a lower quality format has these problems. It is not hi-res, typically has a smaller file size and is easier to decode after all.

Did the OP mention file types? I was under the impression the Reddit thread was a separate discussion not started by OP. I may have missed it though. My pedantic self would argue no Bluetooth audio is capable of true hi-res.
I believed this thread (and my issue) was to do with Bluetooth bandwidth, not directly the file type which obviously dictates the required bandwidth. The same issues persist for me whether it is a very high bit rate lossy format such as MP3 above 990kbps, or a lossless format such as FLAC. It was also irrespective of whether the hardware decode was handed off to the reciever or computed on the handset.
Anyway, for whatever reason having UWB off solved my particular issue. I primarily use lossless media codecs such as FLAC for reference.
At my case it stutters all the way, and the problem doesn't depend on BT receiver and radio interference.
Switching to adaptive mode almost eliminate the problem, but almost only (and how does want LDAC 330 Kbps?).
I have a completely similar situation on this tablet.
And also the problem is solved only by switching to the mode: "balanced audio and communication quality"
