Comment 5 for bug 345627

I am also having this problem but not on my ALC883 sound chip or my C-Media 8768 PCI sound card, only with my usb headset. If I do not open pavucontrol it works fine but if I do open pavucontrol and then close it the usb headset becomes glitchy and scratchy after a few seconds. If I then open pavucontrol sound returns to normal immediately and if I keep it open the sound is fine everywhere. I do have simultaneous output enabled in papref but it does not matter if I choose only usb or simultaneous or if I remove the simultaneous output.

This is on Jaunty with pulseaudio 0.9.14 and has persisted through the last two pulseaudio updates.
