For the future, I have just spotted that the m/b has an SPDIF header that I can easily bring out to back-plate connectors. I am guessing that there is no real need to do this, because it would just carry the same digital audio signal that is currently going through HDMI. But, once again, it is good to have options.

Thanks for your help.

So as a quick FYI in case you explore that in future, SPDIF can't carry 8 channels and can only carry 6 channels with lossy encoding, whereas HDMI can carry both in full fidelity.  If you have a stereo setup it shouldn't make a difference, but if you're doing multichannel, HDMI is meaningfully different.

Thanks - that's useful to know. I had not realized that SPDIF was not the same spec as HDMI audio. If anything, I would have guessed that HDMI was the inferior.

It turns out that I have no need for separate audio cabling. But if I did, my AVR is configured for 5.1 with an optional down-grade for multi-room stereo. So the SPDIF would be enough - especially as my aging hearing can't now differentiate lossless and lossy content .
