ummm no dmix in alsa, do a google for dmix alsa

pcm.dmixer {
	type dmix
	ipc_key 1024
	slave {
		pcm "hw:0,1"
		format S32_LE
		period_time 0
		period_size 1024

		# increased buffer_size
		buffer_size 32768

		rate 44100
	}
	
	 bindings {
		 0 0
		 1 1
	 }
}


this is a fragment of my /etc/asound.conf, notice the bindings option


please also reply to the list, that way other people can get help with
this as well.

Snow-white!  Snow-white!  O Lady clear!
O Queen beyond the Western Sea!
O Light to us that wander here
Amid the world of woven trees!

	Gilthoniel!  O Elbereth!
	Clear are thy eyes and bright thy breath!
	Snow-white!  Snow-white!  We sing to thee
	In a far land beyond the Sea.

O stars that in the Sunless Year
With shining hand by her were sown,
In windy fields now bright and clear
We see you silver blossom blown!

	O Elbereth!  Gilthoniel!
	We still remember, we who dwell
	In this far land beneath the trees,
	Thy starlight on the Western Seas.
		-- J. R. R. Tolkien
