[Elecraft] No K3 Sub Receiver audio

[Ron W3ZV]

OK. I know I am missing something, but I am at a loss as to what it might be. Suddenly, I have no audio on the sub receiver. Sub audio gain knob is up beyond mid scale. I have the SUB selected and Split set to up 1. Speakers are set to 2. Speakers + Phones is set to Yes. L--Mix—R is set to A——b. Headphones work okay. When I swap to Speakers =1, I have audio in both ears. What is the obvious and embarrassing thing that I have missed this time?
