Audio cut out problems w/ Ubuntu 11.10 64bit on Compaq Presario CQ62

[Ego Death]

Hey guys, I did a fresh install of Ubuntu 11.10 64bit yesterday from Ubuntu 10.xx 64bit.

I've noticed that my audio cuts system wide after using either webcam or Firefox (youtube/flash).

I was wondering if there the was a way I could easily view the daemon process to reset it without a reboot.

To restart ALSA (Advanced Linux Sound
Architecture - what loads the audio drivers and controls your soundcard) it is enough to type this

sudo service alsa reload

or use this if it refuses to reload

sudo service alsa force-reload

Now if you just want to restart Pulseaudio (What manages the application sounds and tells ALSA on which soundcard to play the sound) it is usually enough to just kill pulseaudio.

killall -9 pulse

Note: I'm on my phone and the commands are on top of my head

I have what appears to be the same problem. It started with an Ubuntu update maybe 3 weeks ago. Now the sound lasts for the first 5-10 minutes of uptime, but then it goes completely silent. I get the same "unrecognized service" notices, above.
