I’m installing a Sonos Amp with an outdoor Samsung TV. The TV will be connected to the Amp through its HDMI ARC/eARC port, and the cable run will be approximately 20–25 feet.
Because I need to keep the cable as thin as possible, I’m considering a 25-foot active fiber-optic HDMI 2.1 cable rather than a conventional copper HDMI cable. The cable is:
-
HDMI 2.1 / 48 Gbps
-
Active fiber optic
-
Unidirectional
-
25 feet
-
CL3 rated
-
Advertised as supporting ARC/eARC, Dolby Atmos, 8K/60Hz and 4K/120Hz
Can you please confirm whether an active, unidirectional fiber-optic HDMI cable that supports ARC/eARC is compatible with the Sonos Amp for receiving TV audio over HDMI ARC?
In particular, is there anything about the Sonos Amp's HDMI ARC implementation that requires a conventional copper HDMI cable, or should a properly designed active fiber HDMI cable with ARC/eARC support work normally?
If fiber HDMI is supported, please also let me know whether there are any special requirements regarding cable direction/orientation when connecting the TV's ARC/eARC port to the Sonos Amp.
