Description of problem: When watching a youtube video, after a period of time from 1-5 minutes the video stops playing. The video might start again after some seconds, but without sound. Problem occurs in both Opera 10 beta 2 and Firefox 3.5.1. Problem occurs with Adobe Flash 10.0.22.87 and Adobe Flash 10.0.32.18. Libflashsupport is NOT installed. This is on a recent install of Fedora 11 from the 32-bit DVD. Note when video stops, pulseaudio suddenly begins using >70% CPU, then after some seconds it crashes. Version-Release number of selected component (if applicable): alsa-plugins-pulseaudio 10.0.20-2.fc11 How reproducible: Play a youtube flash video that lasts for several minutes. Steps to Reproduce: 1.Play youtube video to completion: http://www.youtube.com/watch?v=K-DdstKANYg 2. 3. Actual results: Video hangs and sound is lost after playing for over 1 minute. Video may resume, but without sound. Expected results: Video to play with sound to completion without hanging. Additional info: Uninstalling alsa-plugins-pulseaudio solves the problem. Unsure of the side consequences of this.

It appears that the problem was more than just alsa-plugins-pulseaudio. While removing alsa-plugins-pulseaudio seemed to fix the problems I was having in youtube (Adobe Flash), the same problem later appeared when playing a test wmv video file - OldRepublic.wmv I found OldRepublic.wmv in a link of the following guide and played it. It played for a time, then the sound quit while the video continued. I decided to perform the steps in the guide, and this allowed OldRepublic.wmv to play properly to completion as well as the youtube video I linked in the opening post. Note that when following this guide, alsa-plugins-pulseaudio was reinstalled. Both OldRepublic.wmv and the youtube video linked above played fine with alsa-plugins-pulseaudio after following the guide.

Exactly what should be done is beyond my expertise.
Sorry, Flash is closed source software. We cannot debug this. Please grep syslog for any PulseAudio related messages and paste them here.
Created attachment 358345 [details] Pulseaudio debug messages This is what Pulseaudio outputs every time I play some Flash video. Note that about four or five weeks ago (when I was last using my Fedora box) it was still working perfectly.

I am really not sure how I could makes this any more explicit in the logs. You snd_pcm_avail is overflowing. *** This bug has been marked as a duplicate of bug 506075 ***
Didn't see that bug... could have looked for it, tho.
