Hi All,
 
I am a new alsa user and I have the following problem:
 
** Presently using alsa-driver-0.5.x. But, in this there are no
subdevices allocatable for multichannel ad-da cards.
   [ad - anolog to digital
    da - digital to anolog]
    
** My current need is support of subdevices for multichannel ad-da
cardss. 
   Which alsa-driver version supports subdevices for multi ad-da cards?
   "amixer" will be of any help to me?
   Shall I make use of ".asoundrc" file (currently I am not using it)?
 
Any quick info on this would be of really great help.
 
Thanks & Regards,
Sailaja

ALSA-0.5 is deprecated. Why don't you use 1.0.5 ?

bash-2.05$ cd alsa-kernel/pci/
bash-2.05$ grep -r snd_pcm_new .
[...]
./via82xx.c:    err = snd_pcm_new(chip->card,
chip->card->shortname, 0, 4, 1, &pcm);
                          ^  ^
               outsubdevs |  | insubdevs
[...]

No. Use "aplay -l" and "arecord -l" to get a list of
available devices/subdevices. Or read the stuff in /proc .
