Greeting to the list, sorry for the bother if this is easy.
I'm bringing up a new system and I am stumped.
When I capture from the card with a live stereo input, the
wav file that gets created only has one channel modulated, the
other channel is zero/noise.
OS: Fedora 2.6.11-1.1369_FC4smp
Card/Chip: Ensoniq AudioPCI / TriTech TR28602
Alsa release: 1.0.10
MB: Asus P5P800
Typical capture invocation:
arecord -v -d 5 -t wav -f cd -D hw:2,0 test.wav
The verbose output looks ok (see below). If anyone can spot anything
and give me a pointer that would fix the problem, it would be most
appreciated.
Thanks,
Mark
