Hi,

I have added proprietary sound cards which are statically compiled in the kernel. Card 0: Name=X, Card 1: Name=Y.

I want to create virtual devices using these cards, like front, left,surround,iec958. I see that this is usually done at /usr/share/alsa/cards/....

Please let me know how this mapping works?

I mean how does aplay -L list these devices by mapping the sound card to the ones in /usr/share/alsa/cards/... I tried creating X.conf and Y.conf there with front,left,surroud,iec958, but aplay -L doesnt seem to recognize them.

Also, I want iec958 card to be one of the cards listed via aplay -L, and defining this in asound.conf gives error with aplay.

Any help will be appreciated.

Thanks, Nitin
