[Elecraft] Audio volume problems

[Matt Zilmer]

Many K3 users have seen this same rotation problem with the AF/SUB and
RF/SUB controls.  Try adjusting the set screw(s).  If that doesn't
work, you may need to contact support for new ones.  With early K3s,
there were some problems with these controls.

Not sure about your audio/volume problem though.  I'd contact support
on this too.
