Comment (by bleak8197):
I have this problem on lenovo laptop. audio codec is Realtek® ALC257. It
supports 24 bit 96kHz stereo.
Also ffplay.exe is problematic. If you watch the first video ffplay also
hangs when playing.
The problem also happened on my desktop pc gigabyte z170 motherboard. Then
I changed the setting to 24bit 196kHz and it was fixed. The audio
microchip on the motherboard is Realtek® ALC887 codec. it supports stereo,
4, 5.1 and 7.1-channel. It supports 24bit 196kHz studio sound.
The laptop has no problems with drivers etc. I also tested with the
drivers that windows auto-installs. the problem persists. i also tested
with the drivers i downloaded from lenovo's support website. the problem
persists.
I installed the ffmpeg codec for audacity. audacity worked fine.
But the problem persists with other players.
I installed audacious on WSL almalinux, it doesn't support DSD.
Audacious on Windows 11 does support it with ffmpeg, but it makes a
scratchy, rustling sound.
I can't figure out what is causing this problem. Is it the audio microchip
(codec) that doesn't support it?
Correction: I misspelled the title and confused it with Audacious's
problem.
The problem with FFMpeg and ffplay is not sizzle. It hangs like in a loop
like play-pause. The sound is intermittent.
I didn't know how to change the title.
