Hi, Feanor,
thanks for your quick reply, although not very pleasant for me

Well, yes I did everything like you suggest - my TV has optical out and also the AE has it (indeed it's a combined analog/digital output and you need a small converter for 3,5mm jack if you use it with optical cable) and I switch on the front panel of the DAC to optical output, but with no joy.

I will try also the coaxial output just to see if this works, although it wouldn't help me as I need optical outputs to work for my setup, but I'm just curious if it would work.

The seller answered my email, so I will see how it will end up.
I will leave feedback later.

Again, thanks for your suggestions and Merry Xmas and a Happy New Year for You and Your family.

Dag
