Sound Blaster USB?

Fri Feb 16 22:13:13 UTC 2007

I have a sound blaster usb that I just bought.  When I connect it to
my computer I get the following:

uaudio0: <Creative Technology SB Live! 24-bit External, class 0/0, rev 1.10/1.00, addr 2> on uhub0
uaudio0: audio rev 1.00
pcm0: <USB Audio> on uaudio0

When I'm playing music with xmms2d, I get no sounds out the head-phone
portion of this device.  However, xmmd status claims the music is
playing.  Here's all the status info I could find.

mixer reports:
Mixer vol      is currently set to  75:75
Mixer pcm      is currently set to  75:75
Mixer speaker  is currently set to  75:75
Mixer line     is currently set to  75:75
Recording source: mic
