Hi,
This stands out to me:
063c:fixme:pulse:pulse_channel_map_to_channel_mask Unhandled channel aux0 063c:fixme:pulse:pulse_channel_map_to_channel_mask Unhandled channel aux1 063c:fixme:pulse:pulse_channel_map_to_channel_mask Unhandled channel aux0 063c:fixme:pulse:pulse_channel_map_to_channel_mask Unhandled channel aux1
It looks like the game is attempting to send audio to those channels, which are not supported by the wine pulse audio driver.
Might be your audio configuration setup is to blame, either operating system or wine. Try running winecfg and setting the speaker configuration to something else, like stereo.
If that doesn't resolve it try using the patch I attached.
I did, in fact, updated wine (after a week) and while the problem was still there, the messages disappeared
