I think there actually is the same issue when running within QEMU: sound

Is there a bug or someone that is working on that issue? I'd be curious to

I've only noticed this through code inspection/gdb breakpoints after you
pointed out the issue you found. However, I'm fairly sure there has
been reports on this mailing list of sound stopping after a while when
watching a video. This matches very closely what you described.
I was thinking of

Maybe there was another email.
I couldn't quickly figure out the threading arrangement in qemu, but if
the main channel is being driven by a different thread than the audio
channel, then I think this patch would have introduced a bug:

red_worker: video streams - adjust client playback latency
--
Of course, that's 18 months ago, so it seems to me we would have found
it by now (despite it being a subtle, unpredictable bug that only occurs
during video playback).
But, just to be sure, Nicolas, would you mind setting the
SPICE_DISABLE_ADAPTIVE_STREAMING environment variable prior to running
the client and seeing if that changes anything?
Cheers,
Jeremy
