Help with USB Audio

[MrFSL]

This is not my first time using linux but it is my very first cry for help.
I am trying to get a "Altec Lansing XT1" usb speakers/soundcard to work.

Debian Testing - 2.6.12-1.686

At first I was getting errors when trying to: modprobe snd-usb-audio, so I recompiled alsa-source and that fixed this problem. Now when I start artsd I get the following error:
"artsd: pcm.c:663: snd_pcm_close: Assertion `pcm' failed. Aborted"
If I try to start arts from the KDE control panel I get: "The application Soundserver (artsd) crashed and caused the signal 6..."
I recompiled arts and still the same error. *Note* This does not happen if I am using the internal speakers and soundcard (snd-intel8x0). I do believe that drivers are loaded correctly because I can: mpg321 -o alsa <mp3file> no problems and sound comes out correctly and kmix/alsamixer work too.

lspci:
Bus 002 Device 003: ID 04d2:9801 Altec Lansing Technologies

cat /proc/asound/cards:
0 [Audio]: USB-Audio - Altec Lansing XT1 - USB Audio Altec Lansing Technologies, Inc. Altec Lansing XT1 - USB Audio at usb-0000:00:1

What is going on? Anyone please help I have hammering at this for days. Reinstalled 3 times now after hacking up my system horribly! Hope somebody can give me a clue cause I am stumped!

It might be permissions on the device. Could you post the output of

ls -l /dev/sound/

Hi,
I'm just dealing with a similar problem, but my device is different (Ego Sys U24). Did you try what suggested on http://alsa.opensrc.org/ ?
Did you test the card playing with aplay??

HTH,
