[alsa-devel] S51 usb support

[Matti Picus]

My X-FI Surround USB card is barely usable. pulseaudio will let me 
control the volume levels, alsa support cannot view any volume controls.

How can I contribute to better support for this card under alsa? I would 
like to get to the point where amixer can control the analog 
input/output volume levels.

I am a capable programmer, but know very little about alsa, where should 
I start?
