Hi,
I recently bought a U24XL as i'm after recording the S/PDIF in from both
the optical and coxial inputs. I'm not using it for anything special so
just running it through ALSA is fine (i don't need JACK or anything).
When plugged in it is picked up and the mixer for it can be accessed
from the speaker symbol on the task bar (i'm running KDE4.2 on openSUSE
11.1).
I installed audacity as this seemed to be the perfect application. It
installed fine, but whenever i try to record it just records a mid
frequency clicking on the right channel only. This is the same with the
U24 plugged in or out and whatever input device i select in the
preferences for audacity. I'm writing here as i'm not sure if it's an
ALSA problem an audacity problem?
Other information - i'm running it on a Dell Vostro 1500 with the
standard intel motherboard soundcard.
If anyone could help me sort this out i'd really appreciate it.

Hi,
If you want to test the sound input you should start with arecord.
arecord -f cd -d hw:0,0 test.wav
You can find the hw number for you card with
cat /proc/asound/cards
- Before you do the recording you should disable pulseaudio if it is
running.
pulseaudio -k
You can always start it again after with
pulseaudio - D
If the recording with arecord does not work you might have an alsa setup
issue.
Cheers.

Thanks, the U24 shows up as card1, there's more information under
/proc/asound/card1, but it doesn't mean much to me.
arecord -f cd -d hw:1,0 test.wav
arecord -f cd -d hw:1,1 test.wav - i thought it would select a
different input if there was one
both produce a completey blank wav file. I also tried changing the "PCM
Capture Source" under the U24XL mixer and repeated the above, but still
just a blank wav file.
Does this mean i have an ALSA configuration problem? I'm also begining
to wonder if the U24 actually works recording the S/PDIF.
