I found one forum post which said that the Alpha "just worked" in
Linux. I needed the capabilities of the Omega, so I ordered one. It
did not work "out of the box", but a few hours with Google turned up
the solution. All I needed to do with create in my home directory a
configuration file ".asoundrc":
$ cat .asoundrc
pcm.!default {
type hw
card Omega
}
ctl.!default {
type hw
card Omega
}
Subsequently, I obtained an Alpha, and found that it, too, worked.
I considered other USB boxen, but to me, the features and
specifications of the Lexicon appeared to be the best for my needs.
These are nice units.
I have running here on various machines Etch, Lenny, Squeeze, and
Ubuntu 10.10; some handle the Lexicon cards more automatically than do
others, but nothing more complex than the above configuration file is
needed.
Of course, the nice thing is that a USB sound card (really a sound
"box") can unplugged and used with any machine.
By the way, today's electronically-balanced outputs can drive either
balanced (that is, professional/broadcast) or unbalanced (that is,
consumer) inputs, automatically. Here, "balanced" means twisted pair
with shield, terminating in either XLR or 1/4-inch TRS phone plug.
And "unbalanced" means coax (like guitar cable). terminated in either
1/4-inch TS phone plug or RCA plug.
