This definitely sounds like a driver bug and not a pulseaudio one. Could you try disabling timer-based scheduling? Edit /etc/pulse/default.pa, by changing the line loading the udev module to add 'tsched=0' at the end (without the quotes). Then restart pulseaudio (or reboot) and try again. -- Saludos, Felipe Sateler
