I apologize to Bill for sending this direct to him.  I meant to send it to
the group.

Thanks Bill.  I saw the quote below in Fred's, KE7X, K3s book which caused
me some confusion.  It seems as though he is saying if you use monaural
headphones then you should not set the speakers to 2.  I don't want to give
up AFX or sub audio.

"You may use a monaural headphone set in this jack (which would short the
ring connection to ground) because the 8.2 resistors will protect the
stereo headphone amplifiers. In this case, though, you should set CONFIG:SPKRS
to 1 . You may use CONFIG:SPKR+PH YES to have audio in both the speaker
output and the headphones. "
