Quick question: In System->Audio, is there any difference between selecting SPDIF output and selecting HDMI output + 2.0 channels?
The only difference seems to be that choosing SPDIF hides the Channel Selection (as it only supports 2) and allows to Limit the Sampling Rate (though this option only seems to be used when Output Configuration is set to Fixed according to the hint)
Same question for Audio Passthrough (HDMI vs SPDIF) if we only select AC3 passthrough + transcoding
Here seems to be no difference if we don’t use DD+, DDTrueHD, and DTS-HD
Apparently HDMI/SPDIF receive duplicated output constantly from what I read in this thread: No Spdif device in system settings
My setup is an Odroid N2 connected to the TV (LG OLED C9) via HDMI, and TV connected to the AV system via Toslink/Optical
I have sound and correctly receive DD on my AV system either when choosing SPDIF or HDMI + 2.0 channels (also it doesn’t seem to matter the passthrought output I choose).
Kodi’s Audio Quickstart doesn’t seem to tell the difference and my google-fu is not helping me.
TLDR - I’m curious if it matters whether I choose SPDIF (and Limit the Sampling Rate to my AV’s input-maximum) or go with HDMI + 2.0 channels.
