Comment 118 for bug 190754

I get the same behavior as just about everyone else here, but I do not thing it's a PulseAudio issue. At first it did seem it was Pulse-related, since thinks worked smoothly when I killed the PulseAudio daemon and used ALSA instead. That is, I could play music, Alt-Tab, switch desktops, listen to audio from Flash sites, all at the same time.

However, when I listen to music with Rhythmbox and play a movie in Totem (even if the movie is paused) I can produce glitches on the music by Alt-tabbing, switching desktops, etc.

I'm on a Pentium M 1.73MHz, with 1GB RAM, Mobility Radeon x300 (fglrx), 2 soundcards (one internal, one USB) and no compiz.

Since I never use the internal card, I don't know if the glitches happen only on the USB one. I will test that and report back.
