K3 speaker or external speaker not muting

[Roger Dallimore-2]

Hello,

I use the PF1 button to toggle my external speakers on/off while having
headphones plugged into the front socket.

The problem is now for some reason the external speaker is on all the
time even when SPKR+PH is switched to NO. The K3's internal speaker
behaves the same way when external speakers are disconnected.

Before I take a look at the audio board has anyone else had this problem
or can suggest the a likely cause, or am I just doing something stupid!

Many thanks
