K3: "lost" CW sidetone in headphones

[K1LI]

Suddenly, I can only hear the CW sidetone in headphones at normal volume when CONFIG:SPKR+PH is set to YES. I can tell that the sidetone is coming from the 'phones when both speaker and phones are on because turning CONFIG:SPKR+PH from YES to NO cuts off the sidetone in the headphones before it cuts off the speaker.

When I unplug the headphones from the jack - whether front or rear - I can hear the sidetone at normal volume in the speaker. When I plug the headphones into the jack, I have to increase the sidetone volume to over 40 (via the front panel MON control) just to hear the sidetone when CONFIG:SPKR+PH is set to NO.

I reloaded firmware (all latest), but no change.

Thoughts?

Brian,

I have not seen an answer yet, and I don't know of a good one, but ---
Have you tried different headphones?
