I have been given a Sony Blu Ray player/home theatre system (BDV-E870 / E370) and i'm wondering if it's possible to connect it to my Smart TV (JVC LT-40C880 40" Smart 4K Ultra HD HDR LED TV) to use as surround sound speakers when i'm watching Netflix etc (I realise there are already a few posts about this!). I have tried connecting an hdmi cable to the ARC input not the tv and it doesn't seem to be doing anything. Any ideas?
Both the TV And BD-HTS have to support HDMI-ARC and your Sony doesn't seem to do that,
Leave the HDMI connection in place for disc playback.
Connect the TV optical audio out to the Sony optical input.
Check the TV manual on how to turn on the optical output, You may need to turn the TV speakers off too,
