ERROR: Could not open audio device: WASAPI can't initialize audio client

[hellishvictor]

Environment

• OS: Win 7 x64
• scrcpy version: 2.0
• installation method: Windows release
• device model: Samsung Galaxy A
• Android version: 12

Hi, I tried the new v2.0, and after of display the android desktop, it shows:
ERROR: Could not open audio device: WASAPI can't initialize audio client: No se ha llamado a CoInitialize.
ERROR: Demuxer error
WARN: Killing the server...
And then it closes, Disabling the audio with "scrcpy --no-audio" works.
Cheers.

Could you try to force an audio driver:

set SDL_AUDIODRIVER=directsound
scrcpy

Or

set SDL_AUDIODRIVER=winmm
scrcpy

?

[hellishvictor]

Ok it works, but it sounds very "robotic".

[rom1v]

#3793?

[hellishvictor]

#3793?

Yeah, the new scrcpy worked like a charm; you fucking rule!
Cheers.

[rom1v]

Does #3793 fixes the problem with directsound or winmm?

[hellishvictor]

directsound

SCRCpy works fine with --no-audio added

Have a nice day.

This errer is back here w/ new v2.3

Could you please replace SDL2.dll in your scrcpy 2.3 directory by the one in scrcpy 2.2, please?

I just tried, same result.
I also tried with the one in SCRCpy v2.1 to no avail.

Thanks for your time and work,

Cheers !

On which version did it work for you? (a full scrcpy release)

On which version did it work for you? (a full scrcpy release)

FYI

Just got the same error on v2.3.1
Android 13
Microsoft Windows [version 10.0.19045.3570]

I tried the previous versions one by one till v2.0, the error kept showing up.
Then I tried to replaced the SDL2.dll with other versions, nothing changed.

Finally, I have to use this command for now, scrcpy --no-audio.

Thanks for your work, bro. Hope there will be a real solution soon!
