How to switch audio hardware source

Hi everyone.

I think my sound on my motherboard does not work. No sound from front or back panel. Bummer. To get around this I bought a plug and play: Creative Labs Sound Blaster Play! 3 external USB Sound Adapter. No linux support from what I can tell.

Knoppix 8.2 does recognize it.
lsusb: Creative Technology, Ltd

Works great in Windows.

/proc/asound/card1 has:
root@Microknoppix:/proc/asound/card1# ll
total 0
-r--r--r-- 1 root root 0 Mar 19 12:04 id
-rw-r--r-- 1 root root 0 Mar 19 12:04 oss_mixer

Cool it shows up, but it gives me no sound.

The weird thing is that when I run a speaker test I can hear it!
speaker-test -c 2 -D hw:1

I didn't expect anything, since the USB has no Linux support.

I was wondering how I could try and default from hw:0 (motherboard sound) to hw:1 (Creative Labs) on boot up. Or even test it using modprobe somehow.

Thanks!
