Hello. My notebook have on-board sound card which is broken. I bought a
USB sound card for replacement. The problem is SuSE detects the old
on-board sound card and still use it for sound output, even if USB sound
card is plugged in.

How do I set SuSE to use my USB sound card as main sound device? I tried
to go to Gnome control panel, go to Sound effect, and there is NO
selection for which device to use for sound output (I checked it very
carefully).

I also try with mplayer by specifying second sound card with parameter:

[repeat the above error message forever at very high pace]

dmesg is full of something like this:

I tried this on Ubuntu too, same result.  Here is my lsusb:

KDE have a small application which also give a lot of detail of the
sound card, however KDE do not allow me to copy-past this information.
KDE help said these sound card information are obtained from simply
reading /dev/sndstat and /proc/sound, both file are missing on my
system.

Any hint?

P.S. I also tried to use good-old oss, by using mpg123, package from
SuSE guru. I tried mpg123 -a /dev/dsp1 and was told only 'oss/alsa/esd'
can be used as -a parameter, which the manual says device name
like /dev/dsp1 IS THE CORRECT parameter for -a. Maybe I am getting old,
I feel my old knowledge no longer useful any more.
