I seem to be having issues with optical outputs on my G61R. It appears only one input is working (01).

Version 1.07/4408

Unusually when I purchased this after having a mad 5 minutes selling all my previous brand new equipment it had to have a new PSU within a few weeks and all of the optical blanking plugs were missing. It has not been a problem before but now I need to use two outputs.

I was hoping it may be something obvious I have not tried or a firmware issue? It could possibly be dirt but I feel unlikely on all of the rest though.
