I also, can only get sound in rythmbox. only oss sound would work for me. I removed pulse and restarted. now ALSA works under the tests and in rythmbox, but i still don't get sound anywhere else. I'm using creative usb headset. there is also an onboard realtek and hdmi sound through the ati 4850. They all show up as options for sound but sound only comes out of my usb headset, and only in the tests, and rythmbox. Thats fine though since its all that i use, but I can't get sound in vlc or anything else.
