[Alsa-user] Any asoundrc, dmix and ice1712 wizard out there?

[Frank B. <fb...@fo...>]

Hallo,

I'm starting to play around with the dmix plugin. I follow the
instructions on alsa-prohject.org regarding software mixing. 

Now on my second card, a SBLive, I can use aplay as expected: 

$ aplay -D plug:dmix some.wav

works fine.

But my first card is a M-Audio Audiophile, which uses the ice1712
driver. It gives me this error: 

$ aplay -D plug:dmix
ALSA lib pcm_dmix.c:1290:(snd_pcm_dmix_initialize_slave) requested format is not available
ALSA lib pcm_dmix.c:1534:(snd_pcm_dmix_open) unable to initialize slave

aplay: main:480: audio open error: Invalid argument

I know, that the ice1712-chips want a very specific stream format, but I
don't know, which one. Could someone help me with setting up the
correct command line options or and asoundrc, that makes a
ice1712-dmix pcm available? Isn't it possible, to read the supported
stream format somewhere in /proc/asound? 

ciao
