[Elecraft] K3 - SSB audio got lost !

[Tommy]

I am having a configuration issue that I have spent hours trying to figure
out and need some help please.

As a CW person, I seldom operate SSB but I am trying to get set up for this
weekend's CQWW SSB contest. I have tried posting two configuration pages
from K3-EZ but with the file size limitation of about 30 kb and I exceed
that. Below are some of my configuration for my K3. In any band in the SSB
portion, I have no audio output anytime I am in the USB or LSB mode, however
if I change from USB/LSB to CW, I have normal audio but of course I can't
copy the SSB signals. This is true whether I have my SUB rx turned on or
not. I have my CM-500 headset plugged into the rear of the K3 and I have
RadioSport RS20S headset plugged into the front panel PHONES jack and I have
no audio in the SSB mode with either or both of the headsets plugged in.
With both headsets removed, I have no speaker audio in USB or LSB mode, but
normal audio in the CW or AM mode.

In CONFIG I have:

SPKRS = 1
SPKR + PH =YES
L-MIX-R = A  b
 
I am pretty sure I have one configuration set incorrect, but using both the
Elecraft K3 Owner's Manual and Fred's 'The Elecraft K3' manual, so far I
cannot find what I have incorrect.

Any helpful suggestions would be greatly appreciated.
