Just tested it and as far as I can tell, only spdif seems a lot louder, analog
output is equal to 6stack-dig.
Reminds me what also a bit strange: the PCM mixer control only appears after I
have played back something.
On detail: - unload alsa, rm asound.state, load alsa, alsamixer (no pcm vol)
- play back something, alsamixer (pcm volume is there)
From there on, it'll always be visible, even after restarts. I also do not
have any channel configuration control (2/4/6 channels). It's just not there.
No matter if I use auto or 6stack-dig.

Sounds a lot like digging into patch_analog.c (a long change/recompile/test
cycle) or is there a way to figure this stuff out during runtime...? Could
you please elobrate on what I should do? Thanks.
