Describe the issue

Volume doesn't work properly on my MSI MAG 271CQR with Mac mini m4Pro.
When I press "volume-" (or set it via panel) the volume gauge decrease, but volume from monitor increases,
and when I press "volume+" (or set it via panel) the volume gauge increase, but volume decreases.
When I press "switch off volume" (or set it via panel) - volume gauge is set to 0, but volume is max=)

Expected behavior

Press V- -> volume decreases.
Press V+ -> volume increases.

Anything else?
