help!
on windows, execute "scrcpy"
can screen, but no audio.

full output in the console:

scrcpy 2.1.1 <https://github.com/Genymobile/scrcpy>
INFO: ADB device found:
INFO:     -->   (usb)      YWT0222A27007035            device  CET_AL00

The console output looks good, there is no audio error.

How is the audio volume on your device?

Run scrcpy -Vverbose and let scrcpy run for a few seconds. What is the output?

Oh, it seems your audio output does not request samples often enough.

Try scrcpy --audio-output-buffer=10 (refs #3793)

Oh, or the problem might be on the device side.

Try the latest version, this might be already "fixed" or worked around.

run scrcpy --audio-output-buffer=10
and update scrcpy version to 2.3.1.
They couldn't even solve it

Could you try with another device to determine if the problem is on the device side or on the computer side.

My guess is that it is on the device side.

If you record your scrcpy session:

scrcpy --record=file.mp4

Then play the file with VLC, is audio working?

Also see #4268, it seems it's exactly your problem.

OK, so there is a problem with the SDL audio output.

Try with:

set SDL_AUDIODRIVER=directsound
scrcpy

#3799 (comment)

but other player also no audio.(This is not important)

These players probably do not support the OPUS format. It should work in Firefox too (or other browsers).
Alternatively, you can record in AAC (scrcpy --audio-codec=aac).
