I have an Edirol UA-25EX that I use both with Eeebuntu Linux and with 
Windows XP. It sounds better than the builtin sound cards (and sounds fine) 
in both uses.

However, the Linux driver only supports CD quality or 48 KHz audio. There 
are a number of settings that work only in high-resolution mode. I wonder if 
they would interfere with the sound when using the device with Linux. You 
might want to check all the little switches and make sure they are correct 
for your use.

Hope this helps,
Mike

Thanks guys. Installing the latest realtime kernel took care of my
problems. In researching the problem I came across a lot of threads
regarding the settings of each of the switches at the back of the
card, the best resource can be found here:

I think if you're using a relatively new version of Ubuntu it's
already done. It wasn't patched with my version 8.04. If you try

sudo apt-get install linux-rt linux-headers-rt

it should tell you whether the patch has already been applied?

Decent realtime kernels are available for Ubuntu 10.04, the Lucid Lynx 
release. I'm using them on a laptop and on a desktop box, with excellent 
performance from both machines. Btw, I'm not running the Ubuntu Studio 
system, just plain 10.04 with a realtime kernel.

Best,

dp

I never bothered with the Ubuntu Studio either. I find nothing wrong
with the normal distro.
