I've bought a seeed voice card as an external GPIO sound card and as a input audio device to use pocket sphinx.After it was installed successfully, i typed "cat /proc/asound/cards" to see my card index and it displayed:
0 [ALSA ]: bcm2835_alsa - bcm2835 ALSA bcm2835 ALSA 1 [seeed2micvoicec]: seeed-2mic-voic - seeed-2mic-voicecard seeed-2mic-voicecard
then i typed"cat /proc/asound/modules" and i found something that i'm not so sure whether right or not:
0 snd_bcm2835 1 snd_soc_simple_card
My question is, how can I use the device which index is 1, or should I say, how I off the bcm2835 and make seeed2micvoicec into the index "0"? And does it supposed to be 1 snd_soc_seeed_2mic_voic in /proc/asound/modules, why it is snd_soc_simple_card?
