Problems with AVR280 optical digital inputs.

Overnight my Arcam AVR280 is no longer producing audio from my Mac Mini. Instead of 'DIGITAL' being displayed on the front display it's 'ANALOGUE'. Nothing has changed & it has always been faultless...

Here is what I have done to try and get to the root of the problem myself:
1. Tried a different optical cable between the Mini & the AVR280.
2. Tried an analogue cable ('headphone' jack to L & R phonos; that worked, but I want digital)
3. Tried a CD player with the optical cables into all three optical inputs on the AVR280, no good.
4. At one point, after about an hour of dicking around, the sound returned and 'DIGITAL' came back onto the front panel of the AVR280, but within seconds the sound quality began to degrade to nothing and then it went back to 'ANALOGUE'. This was a low point. It has also lead me to the conclusion that my AVR280 has a problem.

I have tried my blu-ray, which I connect through 7.1 analogue cables and that works fine. I have also been through the manual, which states that the AVR280 will select a digital signal over an analogue one, but an analogue signal can be selected by holding down the correct source button for two seconds. I don't have any analogue cables connected to the source that serves my mac mini, but it is still showing "ANALOGUE' & I am getting no sound. This is getting in the way of me watching the football please help! Is there anything else I can try? I am also contacting ARCAM directly, but I now live in Finland & I'm not sure if they have any service centers here...

Thanks. :lease:

Unfortunately I would have to say it sounds like a fault on the digital signal processor board. If it is, this is not something you are going to be able to fix by yourself.

In the short term you could connect an analogue output from the Mini Mac at least it would keep you system running for the football.
