Unfortunately, I was mistaken; the front thing doesn't work :(
I've done some tests of just the card itself (the drive can wait until this
lot is sorted). In the following, I set all mixer controls to max. I'll keep
going and sort these issues myself, but just in case it jogs someone's
memory.....
Test of alsarc devices:
When playing without choosing a device ("default" I assume):
* Sound plays through the CENTER, LFE, and SURROUND speakers... and not
through the FRONT ones.
* Active mixer controls: "Wave Center", "Wave LFE", "Wave Surround"
When "front" is chosen:
* Sound plays through the CENTER, LFE, and SURROUND speakers... and not
through the FRONT ones.
* Active mixer controls: "Wave Center", "Wave LFE", "Wave Surround"
When "rear" is chosen:
* Sound plays through the REAR speakers.
* Active mixer controls: "Surround"
When "center_lfe" is chosen:
* Sound plays through CENTER and LFE speakers.
* Active mixer controls: "Center", "LFE"
Test of connectors on the card:
* LIN_OUT1. Does not work
* LIN_OUT2. Works
* LIN_OUT3. Works. Rear Center out not tested.
* MIC_IN. Does not work.
* LIN_IN. untested.
* Digital out jack. untested.
Tone/Bass/Treble seem to work fine.
Questions:
1) Why are there two seperate mixer controls for Center, LFE, and Surround,
each of which is only active at a certain time... is this just a weirdness of
the card, or is this another issue? I'd really rather just have _one_ control
to adjust each setting :)
2) None of the non-AC97 mixer controls allow muting. Is this just a side
effect of the card, or is it feasible for me to add this to the driver?
3) Should "front" just play through the front speakers?
4) What about the Audigy2's extra output, Rear Center? LIN_OUT3 on the card is
a three-way connector, not a two-way one.

Does this mean that on the Audigy2, the ac97 mixer is non-functional? I
patched the driver to disable the creation of an ac97 mixer for Audigy2
cards.. Means I have a _sane_ number of mixer devices, and everything still
works... as well as it did before. Is this a valid assumption? If so, shall I
submit a patch?
