The only hint I can see is that there is a buffer overrun and then
pulseaudio tries to rewind. This most likely signals a bug in the driver,
possibly pulseaudio does something the driver did not expect.

As an additional debugging step, could you try adding tsched=0 to your
config?

Sometimes driver bugs area avoided by using that option
