    For me was the same like @Airgetlam told. Panasonic tv with hdmi ARC input but no multichannel passthrough from hdmi connected input devices, just multichannel from internal tuner and apps.

      Let‘s cross fingers your tvs manual does have info about hdmi passthrough. Anyway imo you should be ready to live with a bad answer. If passthrough isn‘t supported a hdmi switch with audioextractor will be your friend. ICA Smart Service

      Thanks. Unless I get better info. I just wonder why have a HDMI arc if it doesn’t improve anything 

      HDMI-ARC was originally literally “optical over HDMI”, so offered the exact same codec support as s/pdif. However, over time a few codecs were added as the bandwidth is a bit better over ARC than optical (DTS+ I think is one such codec).

      However, eARC is a big step up over ARC (and optical), tons more bandwidth so supports things like mulit-channel PCM, Atmos, DTS-HD etc.
