Comment (by [EMAIL PROTECTED]):
That was a good guess, thanks. The patch at 456 helped quite a bit, but
isn't 100% effective. I'm not sure whether to post there or here, but
what I'm seeing now while listening to streaming audio is that it stops
every so often and the following or something similar appears in the
output of dmesg:
