I've got a (real) cheap usb sound "card" that partially works with ALSA. I can get the microphone input to respond by fiddling with some of the switches, but I have been unable to ge the output functions to work (produce output) at all. The "indicating" (power) light flashes, but I get no sound. Another thing that is weird is that while the litle box has SPDIF connections (both in and out) I don't see them on the mixer panel. Any clues would be appreciated. I have done the upload using 'alsa-info' with the defaults. Some brief details:
lsusb yields:
Bus 001 Device 034: ID 0d8c:0102 C-Media Electronics, Inc.
The output mixer panel shows two outputs (speakers),
The input mixer shows three inputs (2xPCM, 1 Mic).
The switches mixer shows a PCM capture source and a single PCM switch.
Are there any experiments I can do to help out in the investigation? I'm only using aplay/arecord in doing this test, just to make things 'easy' to diagnose.
Thanks for the help.
