K3 SN 3006 can't find any setting to mute the built in speaker

[Jerome S]

Hello all just loving the new K3,  All is well except one thing.   I
don't seem to have any way to mute the built in speaker.   When I plug
in phones either in the front or rear the speaker does not mute.   I
have set the SPKR+PH to  "no"  and SPKRS to "2"

  I did try FW 3.14 and a reload of the other firmware.

 I have a K3/100 with ATU and one optional filter 400hz.   That is it.  
Like I said everything else working fine just this one issue.

Jerome,

Have the "SPKR" set on (1) NOT (2) and that should solve your problem (if it's a monorual/aka
direct speaker (non-stereo!!!!!!!!!!!)

It shouldn't matter what SPKRS is set to - if SPKR+PH is "no", the
internal speaker should still be muted when headphones are plugged in.

Muting appears to be done by an LM4950 on the DSP board. Perhaps Jerome
has a defective one...

Jerome, suggest you triple-check your settings, then contact
k3support[at]elecraft.com

This could be a problem on the DSP board itself, which does the phone
jack detecting.  Please contact k3support.
