I just have pulseaudio and alsa configured to route all the sound to
all the devices, so it doesn't matter which one has my headphones
plugged in.. seems like a simpler solution?

I have a new Dell PowerEdge T110 workstation to
replace the old T105. Both of
them lack any proper sound hardware so I've got USB speakers.
Some time in the process of replacing the system or the monitor (which is a
USB hub and thus changes USB device assignment) sound stopped working in KDE.
It seems that the main problem is that there is some sort of sound hardware
detected on the motherboard (maybe the built in PC speaker) which causes the
real sound hardware to be registered as ALSA device 1.
So far the only way I've discovered to make things work is to make the
following sym-links to make the USB sound hardware be device 0.
# ls -l /dev/snd
total 0

Is there a way that I can reserve device 0 for the USB device? It needs to be
reserved because the motherboard hardware is detected before the USB bus is
scanned - if the monitor is even turned on when the system is booted.
Is there a way I can make the system just ignore the motherboard device and
have only 1 ALSA card? There's only one thing that can ever be useful so it
seems best to make it the only recognised card in the system.
Thanks

Turning and turning in the widening gyre
The falcon cannot hear the falconer
Things fall apart; the center cannot hold
Mere anarchy is loosed upon the world
