[alsa-devel] .asoundrc

Hi,

I am trying to write one .asoundrc file

What i am currently doing is rate conversion

My .asounrc file contains

pcm.sirf3a { type rate slave { pcm "hw:0,0" rate 8000 } }

I am using following command

aplay -M -D sirf3a /usr/share/sounds/alsa/Side_Right.wav

But it is giving me some errors

aplay: set_params:909: Channels count non available

Any idea why this? where I am going wrong?
