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?
