Extreme intermittent jitter on sound with Wine apps via ALSA pulseaudio plugin

[Neil Wilson]

Binary package hint: pulseaudio

The symptoms of this bug are extreme jitter in the sound coming from Wine applications. It sounds like the sound has slowed down massively with huge gaps between each sound.

What is happening is that the Wine application is losing the sound connection and reconnecting dozens of times a second - which causes the jitter. You can confirm the fault by going to the Applications tab in the Sound Preferences applet. You will see that the page flickers between connected and 'no application running' as dozens of disconnects and reconnects are processed.

The jitter effect is intermittent and sometimes stops. Often though you have to restart the Wine application and/or the pulseaudio daemon to get the effect to clear completely.

Please note that there is a PPA with a new pulse backend for WINE.

Yes I know. I created it :-)

Scott asked me to log this artifact as a separate bug.

Yes, I know that, too. :-) I'm just placing it in the public record, so to
speak.

The same issue seems to apply for other programs using the ALSA interface of pulseaudio. I have extremely chopped sound when doing VoiP (SIP). I've tried with different GUIs (linphone, ekiga, twinkle, qutecom - almost no difference). I believe its an issue of pulseaudio.

Sound is clear after deinstalling pulseaudio and using ALSA directly (but then I have issues configuring my different microphones.)
