I just installed a new sound card: CM8738 by C-Media Electronics. Basic installation was a breeze in Windows and Linux. I'm able to play sounds in both systems.
However recording sounds gave me some more trouble. I got this working under windows, but not properly so under Linux
Under Linux, when I say something in the microphone, I actually hear this in the speaker. But I can not record any of it. Under Windows I can.
Here is what I tried:
sohail@thabox:/home/sohail/temp$ arecord -f dat -d 0 rec.wav
Recording WAVE 'rec.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
Aborted by signal Interrupt...
sohail@thabox:/home/sohail/temp$ aplay rec.wav
Playing WAVE 'rec.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
The second command should have produced the recording on the loudspeakers, but I hear nothing.
Using alsamixer, I see that nothing is muted and every thing is turned up max volume.
Any Ideas guys and girls?
