I have tried the patch on clean (unpatched) patch_via.c. dmesg prints out ***PATCH 08/07/10 as expected, but the surround does not work. Surround and cen/lfe controls are also not created for alsamixer without other patches. What does work is specifying -Dsurround40 for speaker-test but there is no sound from rear speakers. If you want, I can post the whole patched patch_via.c somewhere or we can work on new patches starting with this one.

Hello, for quite some time the "Smart 5.1" function in alsa is not working properly when motherboard has only 3 audio jacks.

Please try the patch below.
(This function uses 0x12 and 0x13 as the NIDs for the center/LFE and side DACs. Shouldn't these be 0x24 and 0x25, as per the datasheet?)
