Here's the output:
$ cat /proc/asound/cards
0 [HDMI ]: HDA-Intel - HDA ATI HDMI
HDA ATI HDMI at 0xfea64000 irq 38
1 [Generic ]: HDA-Intel - HD-Audio Generic
HD-Audio Generic at 0xfea60000 irq 16
2 [U192k ]: USB-Audio - UMC404HD 192k
BEHRINGER UMC404HD 192k at usb-0000:00:12.0-1.2, high speed
It does not help me...
