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.
