[Alsa-user] How do I get USB audio to work?

Brian Kendig Mon, 29 Mar 2004 05:50:51 -0800

My Dell laptop is running a fully-up-to-date SuSE 9.0 with kernel 2.6.5-rc2. Internal audio works fine on it, but I have a pair of Apple USB Speakers that don't make any sound at all on it (though they work fine on my Mac).

I've gone into alsamixer and tried raising all of the sliders, but nothing seems to have any effect. I've included relevant system information below. What am I missing, how do I get USB audio to work?

> /sbin/lsusb
