[Alsa-user] playback device not working?

[Brian L S. <br...@ga...>]

Alsa-users,

cat /proc/asound/devices | grep playback
 18: [0- 2]: digital audio playback
 16: [0- 0]: digital audio playback

I have 2 playback devices.

aplay -D hw:0,0 /usr/share/sounds/startup3.wav
Playing WAVE '/usr/share/sounds/startup3.wav' : Signed 16 bit Little
Endian, Rate 44100 Hz, Stereo

fine

aplay -D hw:0,2 /usr/share/sounds/startup3.wav
ALSA lib pcm_hw.c:1172:(snd_pcm_hw_open) open /dev/snd/pcmC0D2p failed:
No such device
aplay: main:508: audio open error: No such device

how come?

thanks,
brian
