Hi Tomas,

The following command lets me record audio from the card,
$ arecord -c 2 -d 60 -f S24_3LE -r 48000 -D hw:1,0 s3.wav
The resulting wav file has all hearable audio in the left speaker when listening.
If you really feed stereo signal into your soundcard stereo input jack and the card is not somehow configured to merge the input channels, the above command does record stereo signal.
Ok, thanks. I have been a bit confused about the relation between the -c option argument and the number of inputs on a card. If I understand correctly, the -c option does not say anything about what inputs to record from, it is saying what kind of audiofile to produce?
Available controls of the card are listed by command
amixer -c 1 contents
Here is the output of that:
$ amixer -c 1 contents numid=2,iface=PCM,name='Capture Channel Map' ; type=INTEGER,access=r----R--,values=2,min=0,max=36,step=0 : values=0,0 | container | chmap-fixed=FL,FR
numid=1,iface=PCM,name='Playback Channel Map' ; type=INTEGER,access=r----R--,values=2,min=0,max=36,step=0 : values=0,0 | container | chmap-fixed=FL,FR
And I didn't mention that in my original post but, alsamixer has been informing me that "This soundcard does not have any controls." when I select the AudioBox via F6.
Is this giving any more hints on what I can do?
Best regards -- Tomas
