On my Raspberry-Pi I use the dummy-driver and then alsa_out to get the

sound to the onboard sound chip (as posted here:

http://www.raspberrypi.org/phpBB3/viewtopic.php?p=196500#p196500 and

here: http://www.raspberrypi.org/phpBB3/viewtopic.php?p=197194#p197194 )
However, I can't get my Edirol/Cakewalk UA-101 to work with the Pi but

I'm sure it's not related to power. I guess it's the Pi's USB host-chip

or its driver which seems to have problem with other devices (mostly DVB

stuff), too. Isochronous transfers (as used by most "professional" USB

audio interfaces) seem to be pretty hard for the Pi :(
