Hi,
I got a cymatic audio uTrack24 recorder and I when I connect it to my linux it recognises it as an usb 24 ch sound card. The device records all 24 traccks into a singe multichannel wav file.
However I'd like to record to my laptop 24 channel in separate files.
So I think I need to edit an alsa conf file.
The application would be like this:
arecord -f cd -D pcm.mic1 -d 10 ch1.wav
arecord -f cd -D pcm.mic2 -d 10 ch2.wav
arecord -f cd -D pcm.mic3 -d 10 ch3.wav
...
arecord -f cd -D pcm.mic24 -d 10 ch24.wav
I dont know how to set up a proper conf file.
Code:
~$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 1: uTRACK24 [uTRACK24], device 0: USB Audio [USB Audio]

I did this so far for the 1-4 channel. But when I record, there is no sound.
Code:

}
pcm.c7 {
type plug
ttable.0.6 1
slave.pcm capt
}
pcm.c8 {
type plug

}
Could you please help me how should this be?
