Comment 32 for bug 301755

I upgraded to Jaunty, today, and got choppy sound from pulseaudio (0.9.14-0ubuntu20). I added Luke Yelavich's PPA to my sources.list to upgrade it to 0.9.15-0ubuntu1~ppa4 and now I've got choppy *and* crackling sound. The tsched=0 workaround didn't work for me. I've got a Creative Sound Blaster X-Fi Platinum; here's my lspci -v:
