The old surround sound system is from 2009 so doesn't support HDMI arc,
only optical in from the old TV of the same vintage.

However thanks for the link above, as that may help me get the Pi in the
living room to do surround sound with the new TV/soundbar. So far I've
not managed to get the Pi to do anything other than stereo.

The Linux laptop with an nVidia card had a bit more luck with that
setup, the 5.1 and 7.1 devices worked albeit with the centre and
subwoofer swapped. When I tried to reconfigure that, I lost sound
completely and had to wind back the configuration.
