- Does 5.1 analog surround work for the ALC662? If yes, how?

Channel Mode [...]
I know this document and while I do have the auto-mute control a channel control is missing.
So, is the ALC662 supposed to have a channel control? (Maybe I'm missing a kernel configuration for it, or what else could affect it?)
You have to post the output of alsa-info.sh
The channel mode should be automatically added for those desktop with three audio jacks (green line out, blue line in and pink mic) at rear panel

either your computer BIOS does not set the correct pin default or it can be disabled by hint
- multi_io (bool): try probing multi-I/O config (e.g. shared line-in/surround, mic/clfe jacks)
Do "pcm playback volume" affect the volume after you change channel mode from 2ch to 6 ch so that mic and line in jacks are retasked as output ?
I can't answer, because of the lack of channel mode.
Any further help is appreciated.
