It sounds like you have the connections correct. HDMI2 is the ARC input of that LG TV, and Main/TV1 is the ARC output of the 901.Hi everyone, I am a new member to this community and also to the Pioneer family as I have had for a trusty receiver... wait for it a 15 year old Yamaha Rx-V650. It had to go due to missing Atmos and multimedia connections options etc. My current setup is 7.1 and I will upgrading to the 7.1.4 setup very soon. I am very impressed with the 901, especially when it comes to the openness of the sound-stage and impact of sound during movie playback (John Wick 3... really excellent sound projection during the gun fights). I typically have a usage of 60/40 (music/ movies) where for music I am using mainly the Direct or Pure-direct for listening (Oppo203 source). Here I believe the Yamaha due to it's B type amp had a bit more of emphasis, it seems as though the Yamaha has a more solid "ground", I can't really explain it But I am very impressed with the sound-stage and instrument placement form the Pioneer, really opens the music (Norah Jone's voice for instance really shines on this receiver), I do not know if it is due to the fact that's it's a refined edition unit or not, but overall the music quality is top notch.
Onto my issue/ problem: I have a LG OLED, model C7V that no matter how I set it up with regards to HDMI ARC (Auto, PCM, Simplink on/ Simplink off) I can not getting any sound to the Pioneer at all. I have set the receiver to CEC and everything is connected as should (Main on receiver and HDMI 2 on TV). This problem is valid for all content on the TV including the build in apps like Netflix, HBO etc. The work around is having an additional cable (Toslink) to the audio input on the receiver.
Anyone with similar issue with their LG HDMI ARC setup, please share your thought.

Maybe you've already seen these materials but just making sure. I am not using the ARC function on my 901 so I haven't worked with this first-hand.
