Hello list!
Today I updated alsa-lib from 1.0.9b to 1.0.11. Until now I was using an
~/.asoundrc that allowed me to (a) play back stereo sound on all four
speakers (by duplicating via the route plugin), and (b) to listen to multiple
audio sources via dmix. I have an ice1724-based card ("Terratec Aureon 5.1").
After the update, I had to add "format S32_LE" to my dmix definition -- why?
The two pcms work; I can either play back using the dmix plugin or have
duplicated sound with my ch40dup pcm. But the combination fails with the
following error message:
ALSA lib pcm_params.c:2152:(snd_pcm_hw_refine_slave) Slave PCM not usable
I will paste my .asoundrc at the end of this E-Mail. Any help is highly
appreciated. :-)
Thanks in advance,
Eric MSP Veith
P.S.: I always thought that my cards supports hardware mixing, that is, doing
the job of the dmix plugin. Am I wrong with my assumption? I could not get it
working until today.
So, here comes the file:
