    I have My Ultimo4K Plugged into my TV via HDMI.
    My TV is connected to My AVR via Audio return channel (ARC).
    My TV will pass 5.1 Dolby Digital / 5.1 DTS audio from my Ultimo4k to the AVR, It will also pass Dolby Digital 5.1 from The Netflix, Amazon Prime, NowTV apps on my TV if 5.1 sound is present.
    What ARC can not do is pass HD audio such as PCM 5.1/7.1, TrueHD, DTS-HD MA, this is a limitation of HDCP and bandwidth, in such a case you need to connect directly to an AVR via HDMI (or you can use multi channel analogue for PCM only).
    VU+ Ultimo 4K 3TB, 1x Twin DVBS-2 FBC / 1x DVB-C FBC/ 1x Twin DVB-T2.
    VU+ Solo4k 2TB, 2xFBC-S2, 2xC/T2, 1x Sundtek .
    1m Motorised Single LNB Dish, 60cm Fixed Octo LNB Dish.
    Samsung 65HU8500 with SEK-3500, Denon AVR-X2200W 5.1.2.
    Oppo UDP-203
    Panasonic 55VT50.

    My box has Dolby Digital, Dolby TruHD, Dolby Digital Plus, Dolby Pulse, DTS TruSurround so is it better not using ARC with mine?
