I have an (old) Onkyo receiver which I have just discovered won't deliver any output from a source connected by a digital optical input.

The receiver settings are correct (AFAIK) with the optical input connected to the source on the receiver (tried with several different of the four optical inputs and more than one source, and with two cables).

The kicker is that it works using the coaxial digital input.

Grateful if anyone has any suggestion about what I'm missing.

You may have to select between coax and optical in the settings. Pretty sure most of my previous receivers have been like that (NB: never had an Onkyo). Don't currently run one.

Keep calm, and carry on posting.

Yes indeed. I definitely selected them accordingly. It's when the OPTn ins are selected it doesn't work

Can you check the optical cables work? Also check for dust in ports, on the ends of the cables. And check the source device is set to output via it's optical port. Maybe search to see if anyone else has had optical input issues with that model.

Keep calm, and carry on posting.

Having had multiple Onkyo receivers, once you have exhausted all other possibilities try a factory reset of the receiver. It normally involves holding in one of the buttons on the front when powering the unit on (owner’s manual will confirm which). Bit of a nuclear option but it at least takes software out of the equation as the cause. I have had success with this avenue in the past.

🤕 faceplant. Note to self... when trying to connect optical inputs don't try and do this in poor light and looking at things upside down. Think about whether 1 is on the left of the right!
