hmm, I'm not sure if this is what I'm looking for. 
I'd like to have an filesystem representation of an mixer 
device's status - separated by channel.

For example, per mixer device tree:


/name			        verbose device name
/channels/			subdir for channels
         /pcm			channel named "pcm"
             /name              verbose channel name (eg. "PCM")
	     /mute		boolean flag for muting
	     /volume-r		right side volume
	     /volume-l		left side volume
         /mic                   channal named "mic"
	  ...
