If i set it to 2.0 and follow these steps for optical: Audio setup and information I simply have no more than 2 channels.
I think something is broken in Vero 4K (I’m on 17.8 beta v402)
Also on one of the page the tutorial says:
“You will be able to play stereo LPCM and will most likely be able to play DTS and DD 5.1 surround (but not DTS-MA or TrueHD) depending on your amplifier’s capabilities.”
(from: Connecting up your equipment for best audio)
while on the other page it says:
" * Number of channels: 2.0 (S/PDIF only supports 2-channel LPCM)" (from: Audio setup and information)
