OK here we go ...;)Prom going to annoy several of you with this ;)


-- OK guys and gals,
Working on my USB quattro issue...

My .asoundrc file looks like this...(thanks to the alsa page)

When I do cat /proc/asound/cards I get this.. (any way to kill that modem
from showing up in alsa mixers)

My bigest dillema are ...

1> How exactly do I modify my .asoind rc file to hit the right hw devoce?
2> how do I start jackd?
3> How do start jackd in the other various modes?

By the way my lsmod looks like this.. ( I blacklisted usbaudio and others
in /etc/hotplug/blacklist)
