Hi all. Well, I have just received my brand new Onkyo HT-S7805 5.1.2 It looks beautiful. It is not fully set up yet as we have bits we need to sort out first. But I have done a test to make sure all speakers work and dvd player, games console and tv all work ok. Most of this came up trumps. However, the speaker wire that came with system for the surround sound speakers is too short for where we are going to put them. On the speaker cable itself it states 24awg. Anyone have any suggestions about what I should buy? My second issue is once all was setup I found out I needed a Optical cable as my TV doesn't support ARC. Not too much of a problem as I have seen these online. But I can not get the TV sound to play through the system? What am I doing wrong?! Remember, before you all crack up laughing, I am very new to all this, so any help would be greatly appreciated. Cheers all.
