Out of the 4 MSI boards I that I have; 3 run the same
Realtek ALC893 HDA CODEC that yours does. The other, the
Realtek ALC1200 HDA CODEC. All four of them work. But I
notice 1 notable difference; that yours reports 2
HDA interfaces:
hdac0: <NVIDIA (0x0fbb) HDA Controller>
and
hdac1: <Intel Wellsburg HDA Controller>
I see hdac0 is disregarded (unused) whereas
hdac1 is enabled, and functioning. I think your problems
quite possibly lies in your (sound) system attempting to
use the first HDA device in the list, which is effectively
disabled. If you can determine a way to tell KDE, and friends
to use the 2nd HDA. Things may well go as intended.
None of the 4 MSI boards I have display 2 HDA's, as yours
does.
If you have any additional questions, you may well find
the FreeBSD forums already have answers to your issue. This
is where I originally found answers to my issues, when I
first started using these boards.
