Subject: patch: ac97_patch.c - enable 'Smart 5.1' on VIA vt1617a ac97 codec - Version 2
Greetings;
This version superseeds the patch presented 070223 (that patch was not accepted)
This patch provides a single 8 way enum called 'Smart 5.1 Select' with some reasonable names for each enum that allows the user to choose which of the 8 possible settings for vt1617a's version of what via calls 'Smart 5.1'.
Setting this new control to the setting 'Surr LFE/C Mic3' allows 6 channel output to be played using the following command:
aplay -Dhw:0,1 chan-id.wav
Note that the existing control Alternate Level to Surround Out may have to be disabled to hear the surround output.
