Description of problem: Audio playback somewhen suddenly stops, cpu usage goes to 100% and the media file played kind of fastforwards. Noticed so far with Rhythmbox playing audio files, as well as videos played with Adobe's Flash player.

Steps to Reproduce: 1. Start Rhythmbox. 2. Select some audio file (tested with .mp3 file). 3. Play it. Actual results: After 2 minutes or three, cpu usage goes up to 100% and playback stops. The Rhythmbox's position display fast-forwards till the end of the file, then the next one starts. The old one is marked as errorneous. Expected results: Audio file plays just fine. Additional info: When watching pulseaudio's statistics with paman, I notice a sudden explosion of the number of currently allocated memory blocks during this 100%-cpu-phase, from something around 300 to far over 800 blocks. paman then reports disconnection to the PA server. Problems must have started with the updates that came in on July, 21st or 23rd. Maybe related with bug 471964, but not sure, so I started a new report. I tried turning off the timer-based scheduling as mentioned there, but it made no difference. Sink is "alsa_output.pci_8086_266e_sound_card_0".
Probably a broken sound driver. Please open a seperate terminal. Run pulseaudio -k there, followed by pulseaudio -vvvv. Now try to reproduce and paste the last 50 lines or so that were generated in the terminal when you reproduced here.
Created attachment 355138 [details] pulseaudio -vvvv log I'm seeing the same behaviour after updating via yum yesterday (sound previously working). This is with Totem, Rhythmbox and flash in Firefox. Following Lennart's suggestion, I played an ogg file via totem after having kille pulseaudio and then running pulseaudio -vvvv in a terminal. Sound works initially then stops and a large amount of messages printed to terminal, and totem eventually issues the following error message in a pop-up dialogue: pa_stream_writable_size() failed: Connection terminated The last 50 lines in the terminal are: <many versions of the three lines prefixed with D:> D: protocol-native.c: Requesting rewind due to rewrite. D: alsa-sink.c: Requested to rewind 42260 bytes. D: alsa-sink.c: Mhmm, actually there is nothing to rewind. Hard CPU time limit exhausted, terminating forcibly. The entire log is attached.

Your driver is broken. *** This bug has been marked as a duplicate of bug 509054 ***
Thanks for confirming this Lennart, and that the problem lies within the recent kernel update. Much appreciated.
