I sent an e-mail to Ketron re this problem thier reply as follows

"We suggest to eliminate the connectors and to sold the white and yellow wire from volume potentiometer to sound generation board PB 414.

I assume they mean solder, now without being stupid re this, I am not suggesting that people start pulling the Audya apart, and ripping connectors off and soldering. What I would do if this is correct is take it to a electronic technician who knows what to do properly and get them to do it.

Can you confirm AJ that this deffinately is the fix to this problem.

Thanks
