First you must find where are these outputs connected.

in file alsa-driver/alsa-kernel/pci/emu10k1/emufx.c
is row with
A_PUT_STEREO_OUTPUT(A_EXTOUT_AFRONT_L, A_EXTOUT_AFRONT_R, playback +
SND_EMU10K1_PLAYBACK_CHANNELS); 

append after it this row
A_PUT_STEREO_OUTPUT(0x0c, 0x0d, playback + SND_EMU10K1_PLAYBACK_CHANNELS);


compile, instal, play something. If they are working, let me know.
If not then try change 
0x0c to 0x12 and 0x0d to 0x13
if stil not working try these too
0x12,0x13
0x14,0x15
0x19,0x1a
0x1b,0x1c
0x1d,0x1e

side L ans R channels are working.
patch used for testing is attached.
is 6.1 and 7.1 Surround support in alsa planed?

I can create volume control (+ controls for mirroring stereo -> 7.1) for
these speakers, and devices something like rearside, and surround71. I
think under linux not many apps uses 7.1 speaker configuration.

Nice :)

let me know when it's done and i'll test it.

7.1 related:
- dts and dolby codecs have support up to 7.1 ( and more ).
- sooner or later an decoder will support that.
- support for this speaker configuration would be a benefit for alsa.

Could you test attached patch audigy2zs_driver.diff ???
Mirroring should work.
There are two new controls:
PCM Side Playback Volume - this is not working for now.
Side Playback Volume - this controls mirroring to side speakers.

This is not final version.
TODO:
- Audigy 2 ZS detection
- alsa lib part

I tried audigy2zs_driver.diff with alsa-driver-1.0.5a.
Seems to work, but as noted above PCM Side doesn't seem to work.

If you would like me to test anything specific other than xmms...
...Just Ask. :-D
