Dear Yu-Hsuan,

Yes, using card index and device index works. Here is the output:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: ALSA [bcm2835 ALSA], device 0: bcm2835 ALSA [bcm2835 ALSA]

card 0: ALSA [bcm2835 ALSA], device 2: bcm2835 IEC958/HDMI1 [bcm2835 IEC958/HDMI1]
 Subdevices: 1/1
 Subdevice #0: subdevice #0
card 1: seeed8micvoicec [seeed-8mic-voicecard], device 0: bcm2835-i2s-ac10x-codec0 ac10x-codec.1-0035-0 []
 Subdevices: 1/1
 Subdevice #0: subdevice #0

As I mentioned earlier I am interested in card 1, the seeed8micvoicec entry. Here it is the conformance test output: 


20 passed, 0 failed

 Set channels 8, format S32_LE, rate 44100: pass
 Set channels 8, format S32_LE, rate 48000: pass

There is probably a bug somewhere on not being able to use the card name?

Regards,
Hin-Tak
