HI
I have a SHuttle 570R6 Mini-PC with I7-11700K CPU and *Realtek
ALC662*audio chip as /dev/pcm4 that was running
a few months old copy of Current-15. I did a quick git pull and
buildworld+buildkernel.
I can say that audio(8) binary is now available. But realtime setting
does not work.
I did set mac_priority_load="YES" in /boot/loader.conf but i did
not help
got: " Security policy loaded: MAC/priority (mac_priority) " in
/var/run/dmesg.boot log.
What are the tricks to be allowed to utilize this
realtime ?

I just committed a new audio(8) utility for viewing and modifying (some)
sound card settings, in similar fashion and format to mixer(8). The goal
of this utility is to concertrate audio settings under one user-friendly
utility, instead of having to (always) deal with sysctls and
/dev/sndstat. The driver-specific controls remain as sysctl-only though,
at least for now.
It prints a lot of information, some of it possibly unnecessary. Some of
the control names or their functionality might be non-obvious. But I
want to start improving those things once I feedback starts coming in.
There are already things in my TODO regarding improvements, but they
will happen gradually.
Please try it out and let me know what can be improved, added, removed.
The man page explains what each control does and whether it is
read-only/read-write.
