This comment was attempted to be added to the ticket but the ticket is locked. So I have added the comment into a second version of the log, for which you have asked.

I've attached a log showing the problem where static is heard during livetv without any seeking or key pushing. The problem starts at 14:57 where a couple of short blips of static is heard. The audio recovers on its own. At 15:00 the static is once again heard. It is only changed to normal with the press of a pause and then unpausing.

The system specifics: Fedora 12 ([brtab@brumar2 ~]$ uname -rm
2.6.32.16-141.fc12.x86_64 x86_64)

pulseaudio 0.9.21

Please attach all output as a file in bug reports.
