> Bug description:
> There is severe lag on all my audio (in Flash, in Totem, in VLC, everywhere) 
> since the upgrade to 8.10 (present in Beta and Final release). The audio will 
> randomly pause for a few seconds (sometimes up to 10) and then continue. 
> Sometimes it will start where it left off, other times it skips ahead 
> different amounts (up to as long as it's been paused). It feels like there's 
> some kind of issue with the buffering (not over the net, but the audio 
> buffer).
>
> I'm not sure if it's related, but the worse problem is that pulseaudio is 
> freezing. In beta this happened when watching flash video and it locked up 
> firefox. Since the full release and a fresh install that hasn't happened, but 
> it continues to randomly lock up Totem and I have to force quit, then open a 
> terminal and sudo killall pulseaudio and pulseaudio -D to get the sound 
> working again. When this happens, sound continues to work in VLC but not 
> flash videos in firefox. VLC has not locked up the sound in Beta or the full 
> release.
>
> There aren't any crash reports to submit. I will open totem through the 
> command line and try to get it to lock up and see what output it shows.
