Could be an issue with the playback program. The "stereo upmix" setting
in alsamixer is only for when stereo is being sent to the card. Some
programs convert stereo to surround on their own *prior* to sending it
to the card. The card then sees it as surround and plays it as-is. If
Firefox sends a surround stream with silence on the front speakers and
sound on the rear ones, the card just plays it as-is since it's a
surround signal.

In this case, wine sends a stereo stream to the card, and the "stereo
upmix" setting takes effect. Which is why I think it's Firefox that's
the issue.
This is my kernel sound config:

Currently I'm rebuilding the kernel without "HD-Audio" and the old alsa
API. I will report back.
For reference, this is my config (for a Xonar D1, which uses the same
driver):
