Hi Kirk,
Sounds like a bum audio jack.
This should give you some insight:

I recently discovered that my external speaker fails to work after
pulling out my headphones. I checked the resistance of the speaker and
it reads 8 ohms, and the DC voltage across the plug (P5) is almost
nothing. The DC voltage out of the audio amp U9 (Pin #6) reads 13
volts. R35/36 should be ok because the headphones work fine.
I think J2 is the problem and could be called a TIF (toddler induced
failure). My son was sitting on my lap listening to "beeping" and he
tugged on the headphone cord. Could this have damaged the internal
switch, keeping it stuck in headphone mode? Is there any way to fix
this?
