In preparation for the arrival of my I-opener (which I plan to use for
playing mp3's, among other things), I bought a cheap soundcard for my
NetBSD server and started playing around with it. One thing I've noticed
is that, while the "PCM" mixer control in xmmix works just fine for
controlling the volume of computer-generated audio (mp3, etc):

1) The CD mixer control has no effect on the CD volume

2) Left and Right are swapped for the PCM mixer - turning down the "R"
   reduces volume of the left ear in my headphones, and vice versa.

I also tried xmix, and it gave similar results.

So, 1) any ideas why the CD mixer control doesn't work?, and 2) is there
a switch somewhere to swap left and right?

Here's the dmesg output for stuff related to the card (could I get
better results by disabling wss and using some other driver?). I'm
running -current as of a couple days ago:
