Steve,
Most likely the isolated contacts in your headphone jack have failed.
That failure has been discussed many times in the past.
If you are using a 1/8 inch to 1/4 inch adapter on the headphone jack,
don't do that anymore, the weight of an adapter exerting side forces on
the headphone jack is suspected to cause pre-mature failure. Build or
buy a short stereo extension cable and put the adapter on the cable. A
right angle 1/8 inch jack at the K2 end may be a help.
For some reason, a few folks have experienced multiple failures of the
headphone jack while others had had no problem at all. The real reason
remains a mystery to me.

I just lost the speaker audio in my K2/100, but still have audio through the
headphone jack. Switching to the regular cover and speaker doesn't help.
Looking at the schematics, it looks like the headphone jack could be faulty.
The speaker audio runs through the headphone jack and bypasses the speaker
when a headphone is plugged in. It looks like the headphone isn't returning
the audio back to the speaker line when the headphone plug is removed.
