Hi Pete,

Sounds like there may be a problem with the G61R.

If you have a backup of the configuration, try a reset (re-type) and see if that resolves anything.

Has the unit ever been serviced? It is common for the card connectors to oxidise and lose connection.

Is the volume control smooth when an active digital source is connected? (i.e., is it sluggish, or jumpy?) - Even if nothing is coming from the speakers.

Let me know if I can help.

Cheers,

Steve
