I didn't have any problems with UA-25, provided you use a 2.6 kernel, ALSA 
1.07 and tweak a bit the jackd buffers to avoid clicks. You can see a 
previous post of mine in the january archives of this list.

Bear in mind that UA-25 does not provide mixer controls, so you cannot use a 
mixer-like program to control the volume of sound. You have to adjust the 
level at the program that is producing the sound (CD-player, softsynth, 
audio sw...)

Which is the output of

cat /proc/asound/cards
cat /proc/asound/card0
cat /proc/asound/card1


If you can see there the audio/midi devices provided by the UA-25, there 
should be no problem at all.

Good luck,
