[linux-audio-user] Terratec Aureon 5.1 USB mic input trouble

[Peter Brinkmann]

Hello,
I recently bought a Terratec Aureon 5.1 USB soundcard for my Dell
Latitude C640, running an up-to-date installation of Fedora Core 3
as well as Demudi 1.2.

I managed to get the soundcard to work with the software I care
about (e.g., jack, rezound, ogle, mplayer) by making it the default
soundcard for ALSA, hacking configuration files like .oglerc, and
experimenting with alsamixer.

There's one remaining problem, though. The input levels from the
microphone and line in are extremely low. I've sort of managed to
record from line in, but the input was very faint. When recording
from the microphone, I can hear (and record) a little spike when
switching the mic on, but nothing else. (The mic works fine when
attached to the onboard soundcard.)

Since I am getting some sort of input, I'm fairly sure that I haven't
muted any of the pertinent channels, but so far I haven't been able
to increase the input to acceptable levels. Any thoughts would be
appreciated.
Thanks,
    Peter
