I am about at my wit's end with this (hence the avatar). I'm not a AV hobbiest, just a user. However, I was given a Sony Bravia Surround SOund and now I can't figure out how to make all this work. I've been doing research everywhere, looking at my manuals - just too many variable. Please note that if it's going to take major hacking to make this work, I'd rather get a new HD tv. The old one was nice enough, but I've been thinking about going HD anyway, so this might be a good time, especially if I'll end up spending $100 on cables and such otherwise. Here's my equipment: AT&T U-verse box connected by R6 coax to the TV (pretty sure it's R6; it's 18 gauge and I read that's R6) TV: JVC I'Art AV-27WF35 - RCA cables (red, yellow, white) connector on back plus a gaming one on front; red, blue, green connector on back; maybe an optical port too, but no HDMI. I could have sworn this was HDTV -ready when I bought it, but I don't really know how to change it to HD. Sony Bravia DAV-TZ140 connected by RCA cables (red, yellow, white) to TV Roku XS connected by RCA cables (red, yellow, white) to TV, Ethernet to AT&T modem I have set up the Bravia and tested speakers - they all work. When I had audio outs from TV into Bravia, DVD player (which is also in the Bravia receiver) sound came out of surround speakers, but the TV and Roku only come through TV speakers. I don't know enough to figure out why sound has to go through TV to receiver to speakers, or if some of my cables are simply analog and thus don't have surround sound to be played, or what... any help is appreciated!
