I have a Sony head unit in my car and the sound keeps going off and the ATT

This looks like the Attenuate function is not working correctly, used to
work fine.
Any clues as to how this can be checked/fixed? or is a new unit needed?

If the phone mute lead on the back of the unit is intermittantly
touching down to ground, this will cause the unit to mute in this
manner.

Wot he said, you've got dodgy wiring.
