Some sound is broken (vlc, flash in firefox) for external USB audio

My headphone jack in my laptop is broken so I use a usb sound adapter for audio. This has worked fine for me, but when I recently reinstalled and upgrade KDE 4, only system sounds worked (I'm using 4.2 beta 2 right now, but had the same problems in 4.1). After a recent amarok update, amarok sound started working. I still cannot get sound in flash to work in firefox (or konqueror), and sound in VLC also does not work.

I kept getting messages about pulseaudio failing, so I ran 'sudo apt-get install pulseaudio' and the message went away, I presume that means that pulseaudio is working now. I thought it shipped with KDE, was I mistaken?

When I try to run "alsamixer" I get the following message:

alsamixer: function snd_ctl_open failed for default: No such file or directory


By the way, I've disabled my onboard sound by blacklisting snd_hda_intel.

When I try to play sound in VLC, I get the following command-line output:
