Hello,
*** description :
I want to record wav files from several *identical* (except for serial
number) usb audio soundcard.
My sound cards must appear in the right order. For example, physical
card called n°1 must always correspond to the same name
(/dev/snd/pcmC1D0c for example), whatever is the pluging order.
This part is done easily with UDEV and is working.
*** question :
Now my problem is that no one seems to use /dev/snd/pcmCxDx to access
cards ?
For example, I can't find how to tell to arecord to use
/dev/snd/pcmC1D0c device.
arecord use -D parameter with card and device number (-D hw:1,0 for
example), but these parameters are *not* affected by UDEV. So my UDEV
rules are useless for arecord.
Same for other programs I found : ecasound, ... each program seems to
access the cards using hw:x,x parameters and not the /dev name.
*** in other words :
I just want to know how to record a wav file from a given physical card
; knowing that I have up to 5 identical cards except for the serial number ?
I have done a lot of search on google and the mailing list, and I was
unable to find a solution. The "index=" parameter when loading module is
not applicable to me because the cards are the same. Sorry if my problem
has been already asked.
Regards,
Xavier
