Urgent: how to address soundcards

Hi,

we are preparing the Utrecht presentation and I run into an problem with multiple soundcard setup.

There are following devices:
cat /proc/asound/cards
0 [I82801DBICH4 ]: ICH4 - Intel 82801DB-ICH4
Intel 82801DB-ICH4 with ALC202 at irq 10
1 [Aureon51MkII ]: USB-Audio - Aureon5.1MkII
TerraTec Aureon5.1MkII at usb-0000:00:1d.1-1, full speed
2 [Aureon51MkII_1 ]: USB-Audio - Aureon5.1MkII
TerraTec Aureon5.1MkII at usb-0000:00:1d.0-2, full speed

In the campcatser-studio and scheduler settings, the only terms which are work are "hw:0,0" and "default". In the system settings I can mark 2nd or 3rd soundcard as default, which works fine in the studio than. But I can't use "hw:1,0" nor "hw:2,0" in the campcaster-studio/-scheduler. It does not playback. For alsaplayer those device strings (-d parameter) are fine.

Any idea how I can address the 2dn/3rd card otherwise in campcaster? /dev/dsp(n) also not working.

Best,
Sebastian
