Can you run alsamixer logged in as root?

VLC plugs directly into pulseaudio, while the firefox flash plugin uses ALSA to play sound. Do you have the pulseaudio-alsa package installed?

I have had a similar problem before. Sound would occasionally be controlled by ALSA and occasionally be controlled by pulse (the pulseaudio-alsa package did nothing). As far as symptoms, sometimes other applications would not produce sound while a flash video was playing and vice versa. Ultimately, I just removed everything pulse/ALSA-related, deleted (and backed up) my configuration files, and installed all related packages anew. It works now. I still don't really know what the problem was.

I thought i read somewhere that flash or firefox or chomium or something was not pulseaudio capable so it would default to alsa and thus only one or the other was able to handle the sound card at once.

I really don't understand why so many people use pulseaudio for such simple setups. For more advanced things I think it is pretty great, but if you are just playing some sound out of your speakers, alsa is the way to go.

Many DMs favor pulseaudio (e.g gnome), so it tends to be run as a dependency, rather than as a conscious choice.

This is true, but I saw floating around somewhere a dummy package that is empty and simply indicates to the system that pulseaudio is provided. So you may then use alsa like normal.
