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.
