Speaker relay? Yes, that will stop you hearing it, but it doesn't fix

** Speaker muting relays have been standard features in countless home
and professional audio amplifiers for decades. Their main purpose is to
stop transients at switch on/off from being heard.

They can also include a circuit to make them drop out if they detect a
large DC offset. Very good way of protecting speakers in event of a fault.
