This patch adds the support of "Channel Mode" enum control to Realtek auto-parser. When line-in or mic-in jacks are capable to output and free DACs are available, the driver allows to switch to multi-channel mode via "Channel Mode" enum switch, as already implemented in some preset cases.
Not implemented in all Realtek codecs. Currently, ALC880, 882, 861, 662 and the compatible codecs are supported.

Why the line out become "speaker" for G41M-ES2L with 3 audio jacks at rear panel ? The driver won't create "Channel Mode" control and it cannot support surround51
It's just because of pin fixup that I'm going to revert.

Even revert the pin config, and distable auto mute,
the channel mode still allow 2, 4 or 6 channels
IT seem that there is no way to use "HP" as "Side" to support surround 7.1 as mentioned in the user manual (Chapter 5 Appendix)

It's simply not supported for now. As already mentioned, all multi-io jacks have to be in the same location. And, it must be line-in or mic-in jacks.
The implementation of hp-i/o switching wouldn't be too difficult, but a bigger missing piece is how to detect such a configuration reliably.
