Audio devices

I seem to have lost most of a weekend to the exploration of Linux 
distributions for AMD 64.  :-)  First impressions have me leaning 
toward SuSE 10 as the best combination of usability/simplicity and 
flexibility.  (I'm using Debian on my older system, but the Debian AMD 
64 web site sounded like more of an adventure than I was prepared 
for...but, who knows, I've got a spare partition for experimenting.)  
The "serious" stuff that I wanted the new box for all seems to be going 
ahead OK, like database, development tools, general desktop utilities, 
server applications....

Sound is hanging me up some, however.  I had hoped to migrate my music 
toys over to this system as well and use such things as Rosegarden and 
Arbour.  To support that, I was intending to attach a USB "soundcard" 
that I've been using on a Macintosh.  It's a Tascam US-122 with line 
in/out, MIDI, and connections for studio microphones.  There is also a 
soundcard on the motherboard (ASUS A8N-E with Realtek AC97).

If I don't configure the USB box, audio works OK. (Once I discovered 
that the default KDE CD player, KsCD, doesn't produce any sound, that 
is!  Kaffeine is fine.)  If I try to configure the US-122, I get no 
output.  What I see is that the device is on the USB hardware list as 
"Tascam Unclassified Device".  The correct driver seems to be 
associated with it: snd-usb-usx2y, which is also aliased to snd-card-0 
according to a modprobe sound configuration file I tripped over.  I 
discovered a site that discussed usx2yloader  and firmware mods and, as 
best as I can understand it, that's all in place.  This is all 
happening with ALSA selected as the sound system.

(Of course, if I boot my Windows XP partition, the Tascam just 
works...sigh.)

Any suggestions of other places I should be looking?
