[Protux-devel] [Fwd: Re: [Alsa-devel] available sampling rate detection]

[Martin Herren]

there seems to be lots of interesting functions at 
http://www.alsa-project.org/alsa-doc/alsa-lib/group___control.html
for detecting all cards and interfaces... haven't had time to try it 
yet, but i will experiment with it as soos as i got some time.

I think you case use a loop with snd_card_next

from alsa-lib/src/control/card.c
/**
* \brief Try to determine the next card.
* \param rcard pointer to card number
* \result zero if success, otherwise a negative error code
*
* Tries to determine the next card from given card number.
* If card number is -1, then the first available card is
* returned. If the result card number is -1, no more cards
* are available.
*/
int snd_card_next(int *rcard)
