I'm puzzled. This is -current as of yesterday (April 20th).
>From /etc/rc.conf.local:
usbhidaction_flags=-f /dev/uhid0 -c /etc/usbhidaction.conf
/dev/audioctl0
My /etc/usbhidaction.conf:
Consumer:Play/Pause 1
echo 'cycle pause' | socat - /tmp/mpvsocket
Consumer:Volume_Decrement 1
sndioctl output.level=-0.1
#mixerctl outputs.master=-8
Consumer:Volume_Increment 1
sndioctl output.level=+0.1
#mixerctl outputs.master=+8
Consumer:Mute 1
sndioctl output.mute=!
#mixerctl outputs.master.mute=toggle
But alas, nothing happens when I press the respective buttons on my
keyboard.
Running from command line works, but not as root/doas..
Running with doas: $ doas sndioctl output.level=+0.1
default: can't open control device
Running as myself: $ sndioctl output.level=+0.1
output.level=0.6
