I've now read some of the code of /usr/bin/mixerctl in the NetBSD
source tree. They need a fair amount of code and various calls to
ioctl() to set things up correctly before they do the ioctl() that does
the actual work. If I were to mimick that way of using the mixer
interface, is there any kind of place where I can do the initialization
just once, and then have a mute/unmute mixer_ctrl_t set up, which I
just have to send to the device in the set volume function? I would
rather avoid having to enlarge the routine by almost a hundred lines of
code.

Regards,

Alexander
