Below is a heavily commented patch against 1.6.2 that fixes the issue. It's very simple, but the same patch to read the mixer volume has to be applied in 3 places, and the patch for setting mixer volume in 2 places. That code should probably be factored out to separate functions.
Let me know if you need any more input from me before importing the changes. I've added this to the FreeBSD port, which will be committed shortly pending poudriere testing.

FreeBSD 14 changes the API for the mixer utility, now reporting speaker volume, etc. as a fraction rather than a percent, e.g.

I'm looking into it myself, so no action necessary at this time, unless someone wants to help. We'll need to check the FreeBSD version within the code, or selectively patch the code in the FreeBSD port framework.
Mainly just want to document the issue here.
