I also found this http://karuppuswamy.com/wordpress/2010/10/04/how-to-get-usb-sound-adapter-0d8c000c-working-as-primary-sound-card-in-debian-linux/ When I googled, I was adviced to try without USB hub. So I directly connected to Server without using external USB hub… but no improvement. I don’t have any other audio device (not even internal audio card). Debian Squeeze does not come with alsaconf utility to detect and install the necessary modules. It is done automatically. In my case it loads all modules and also there is no error message while starting ALSA at startup. Then I looked at /etc/modprobe.d/alsa-base.conf file. I noticed the following at end of file. # Keep snd-usb-audio from beeing loaded as first soundcard options snd-usb-audio index=-2 I just caught the culprit. Basically these external USB sound adapters are used as secondary audio device, the above setting prohibits USB sound adapter being set as default device. In my case, it is a primary audio device, so I set it’s index as 0 as shown below. # Keep snd-usb-audio from beeing loaded as first soundcard options snd-usb-audio index=0
