I'm currently using an iMic USB sound card on a net5501 system. Before
I was using this (the iMic), I was using a Startech USB sound card (here
on Newegg: http://tinyurl.com/5v4n4k). I had errors with that card
which led me to the iMic.
I have a HD radio hooked up to one USB port for control. It has analog
stereo output that, on another system, I ran into the sound card through
the Line In jack and used the output jack to go to my speakers. I also
use input stream with Icecast2 for my LAN. This worked fine with a PCI
Soundblaster.
With the Startech USB sound card the sound from the Line In went to the
speakers with no problem, but whenever I tried to read that sound stream
with darkice or anything else, I got errors that I tracked down to not
enough bandwidth to send the audio signal from the card to the USB port.
I dont' have access to this new card. Before running alsaconf, when
the card was hooked up and I wasn't getting error messages from amixer
or alsamixer, here's the stuff from /proc:
[EMAIL PROTECTED]:~]$ cat /proc/asound/cards
0 [system ]: USB-Audio - iMic USB audio system
Griffin Technology, Inc iMic USB audio system at

0: [ 0] : control
1: : sequencer
16: [ 0- 0]: digital audio playback
24: [ 0- 0]: digital audio capture
33: : timer
It looked like alsaconf just matched it with the first driver it could,
a Yamaha one, but when I deselected that as a choice and ran alsaconf
again, when it was done, there was no card. Here's output from the
first time I ran alsaconf:

-----------------------------------------
After it runs, there's no sound cards in /proc/asound/cards so alsamixer
or anything else won't run. Since it looked like it was just grabbing
the first driver to use, I eliminated the Yamaha drivers (Kept getting
"Yamaha OPL3-SA soundcard not found or device busy" when I ran dmesg.)
Then I ran it again with this output:

--------------------------------------
Still no card listed in /proc/asound/cards.
I can change back to the Startech card and test and report any errors
with that card if that will help.
Okay, a few questions:
1) Does anyone have a Startech or iMic USB sound card working so they
can verify they do work with arecord so it's possible to read the sound
stream?
2) Could the type of system I'm on (net5501) be creating the problems?
Even though it does USB 2.0, could there still be a problem with the CPU
not being able to handle this?
3) Could having other devices on the USB hub cause this problem, even
though I still had the same problems when I disconnected all the other
devices?
4) Any ideas what I need to do to get a USB sound card (preferably one
of these) working?
5) Does anyone have a USB sound card they can recommend that I can count
on to work with Debian Etch?
I just am not sure how to get either of these USB cards behaving.
Thanks for any help!
Hal
