Windows 10: Sample rate of class compliant bluetooth devices fail to be auto-recognized correctly in...

Windows 11 has a well documented issue rwhereby the OS fails to recognizing the correct sample rate off some class compliant bluetooth earbuds and headphone devices playback. There are multiple threads here, that are exploding all with the same issue and it is not certain that Microsoft has even acknowledging that this issue exists. Devices are falsely recognized as 48 Khz sample rate, instead of 44.1. Hence, the bluetooth connection is established correctly, but the playback fails. In many instances, the only solution is to go hands-free, but this will set the sample rate to 12 khz telepho

sample rate / bit rate low wont adjust /

That's the correct sampling rate.

Standard Bluetooth has a microphone sampling rate of 8 KHz. Higher priced corporate Bluetooth headsets has the optional Bluetooth mSBC codec which has a 16 KHz sampling rate.

List of Bluetooth profiles - Wikipedia

If connected by USB, sampling rate is determined by the Analog to Digital Converter inside your USB headset. Basically all USB mics have 16 bit 48 KHz sampling rate. Just look at the Blue Yeti USB mic, 16 bit 48 KHz.

changing recording device sample rate

I'm trying to adjust the sample rate for a recording device but under device properties there is no advanced tab?

 

Cannot set Bluetooth speakers sample rate in Win 11

The same problem appears with three different notebooks (all Huawei brand) after upgrading them from Win 10 to Win 11 (everything was ok with Win 10). Sound is distorted (frequency lowered, breaks) during playback on Panasonic SC-PMX92 micro tower. The sample rate in device settings is 48000 Hz and there is no option to change it.

Under Windows 10 the selected sample rate was 44100 Hz, there was a pulldown list for changing it and the sound was perfect.

The Win 11 updates installed do not change anything. Stuck at 48000 Hz and distorted sound with no way to change it.

Looks like a more general problem with Win11 Bluetooth sound.

There are no custom drivers for SC-PMX92 - everything works with Windows builtin stuff.

Disabling/re-enabling, removing & reinstalling device, sound troubleshooting doesn't change anything.

Dear Microsoft, please fix the problem.
