Bug#581624: pulseaudio: Stuttering playback from Wine

It appears that this breaks other software such as skype[1], and the workaround would be to actually raise the latency. Quoting from the link: Applications can ask PulseAudio for the latency that they wish to have (the amount of time between writing out a sample and it being played out the speaker/headphones/whatever). Skype seemed to have some weird buggy math that only kicked in at low latencies (20-25ms or less) that caused the problem you saw. Setting PULSE_LATENCY_MSEC forces the requested latency (60 is pretty safe across most setups), making sure this bug in Skype is not triggered. Rather than change the default, perhaps wine can set PULSE_LATENCY_MSEC? Applications that are buggy with too high or too low latencies will probably exist always. I don't know what should we do in this case.

Bug#581624: pulseaudio: Stuttering playback from Wine
The discussion here: http://bugs.winehq.org/show_bug.cgi?id=28282 suggests setting default-fragment-size-msec=5 in /etc/pulse/daemon.conf, and that solution works for me. The default is currently 25 milliseconds, which does seem kind of long, and very likely the cause of overflowing the buffer that results in stuttering. It probably makes sense to change the default to 5 rather than 25. Best wishes, Mike -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Bug#581624: pulseaudio: Stuttering playback from Wine
Package: pulseaudio
Version: 0.9.21-1
Severity: normal
I listen to music using Spotify running under Wine. Every now and then
-- I don't know exactly how to provoke it, but leaving the machine idle
for a few hours is usually good enough -- the audio output of Spotify is
unlistenably choppy, and not in a way that recovers as described in
#523389.
I get the same problem on two machines running a squeeze/sid mix (one
with a stock 686 kernel, one with a tuned low-latency kernel with
PREEMPT and HZ=1000, specifically configured to keep JACK happy) and on
my laptop which runs Ubuntu Lucid (with stock kernel). No, I'm not
actually trying to run JACK at the same time as Spotify.
I'm blaming PulseAudio for this because I've not found anything I can do
to Spotify or Wine to make the choppiness go away, but if I set the
card's profile to `off' and then back to whatever it was before, the
sound immediately becomes fine. I have the following (deeply
unpleasant) script saved as `~/bin/kick-pulseaudio'. It gets a lot of
use.
#! /bin/sh
set -e
pacmd list-cards | sed -n '
/^[[:space:]]*index: / {
s///
h
}
/^[[:space:]]*active profile: \(.*\).*$/ {
s//\1/
H
x
s/\
/ /
p
}
' | while read index profile; do
pacmd set-card-profile $index off /dev/null
pacmd set-card-profile $index $profile /dev/null
done
I realise that this is probably very hard to track down.
