[Elecraft] K3 -- Strange speaker problem

[Joel Hallas]

Tonight, when I turned on my early (sn 431), but upgraded to current, K3, I
was surprised to find I had no speaker audio with either internal or
external speaker(s). My first thought was that I had somehow fried the
speaker AF amp chip. But then I found that the speaker audio worked fine if
the CONFIG were set to SPKR + PH = yes. That would seem to rule out the
speaker amp as the problem. 

Anyone experience this, or have any ideas?

Thanks much!
