Binary package hint: pulseaudio

When I watch a flash video in firefox after some minutes Firefox crashes while Pulseaudio is creating nearly 100 % CPU load.
After I close or restart Firefox Pulseaudio seems to be working normaly.

Im using
Ubuntu 9.10 (64 Bit Version), libflashplayer.so (Shockwave Flash 10.0 r42)

Please reproduce this issue using the most current live cd of Lucid (no need to install it; just boot from the cd): http://cdimage.ubuntu.com/daily-live/current/

Hi Daniel,

I've just installed Lucid. After watching a flash video for about 10 mins, suddenly the sound disappeared, but firefox did not crash and pulseaudio did not create a very high cpu load.
nevertheless the sound is gone.

Can you reproduce this symptom using linux-alsa-driver-modules-$(uname -r)
from ppa:ubuntu-audio-dev?
