The Surround controls exists:
amixer sget Surround
Simple mixer control 'Surround',0
Capabilities: pvolume pswitch
Playback channels: Front Left - Front Right
Limits: Playback 0 - 31
Mono:
Front Left: Playback 0 [0%] [-46.50dB] [off]
Front Right: Playback 0 [0%] [-46.50dB] [off]
amixer controls | grep Surround
numid=20,iface=MIXER,name='Surround Playback Switch'
numid=21,iface=MIXER,name='Surround Playback Volume'
But for the life of me, i cant find the code that implements it!
There are many implementations inside of the hda directory, but those
dont have anything todo with non hda things, the only item in the ac97
directory is for AD18XX:
ac97_codec.c:958:AD18XX_PCM_VOLUME("Surround Playback Volume", 1)
This shouldnt have anything to do with VIA 1618 stuff, right?
tnx!
