Subject: [Qemu-devel] [PATCH v4 11/14] paaudio: fix playback glitches
Date: Mon, 19 Aug 2019 01:06:56 +0200
Message-ID: <aa4e3613122ccbaa62b1feb4e427260731f7477c.1566168923.git.DirtY.iCE.hu@gmail.com> (raw)
In-Reply-To: <cover.1566168923.git.DirtY.iCE.hu@gmail.com>

Pulseaudio normally assumes that when the server wants it, the client
can generate the audio samples and send it right away.  Unfortunately
this is not the case with QEMU -- it's up to the emulated system when
does it generate the samples.  Buffering the samples and sending them
from a background thread is just a workaround, that doesn't work too
well.  Instead enable pa's compatibility support and let pa worry about
the details.
