Hi guys, Newly registered on the forum in the hope that you can fix this problem that I cannot get my head around. I've just moved in to a new house and my landlord/roommate has cable with TiVo. I've bought with me a Sony 5.1 surround sound system that I've had for a couple of years but I cannot for the life of me get the sound to play through the surround no matter how I connect the bloody thing. The hardware: TiVo box - Samsung manufactured (initially connected via HDMI to TV) TV is a Philips 37PFL5522 (Philips 37PFL5522D 37in LCD TV review - TV - Trusted Reviews) The surround sound system is a Sony STR-KS1000 which I know to be fully working as I've tested it in other set ups on every possible input. I've also ensured the Tivo box was set to Dolby Digital (not PCM) Now to the problem: I cannot get the SS to 'pick up' and output the audio from the Tivo box in any way shape or form. The tivo box has HDMI, Scart and Optical Audio outputs. At first I tried connecting everything with HDMI as follows: TiVO >>>HDMI>>> Sony SS >>>HDMI>>> TV This worked is as far as changing the inputs on the SS affected the output of video but nothing happening regarding the sound. It was as if the SS was just ignoring the sound carried on the HDMI. So then I thought, I'll try the optical jack since the Tivo and SS both have them making the set up: TiVo >>>HDMI>>> TV TiVo >>>Optical>>> Sony SS But still no dice - i was checking that I was on the right inputs at every point so I don't believe I was doing anything extra stupid. At this point I was running out of ideas so I tried the first set up with the optical on top of it so the audio was carried on 2 paths essentially but still nothing. Lastly I tried a scart to RCA input and I'm still getting nothing on any of the RCA/Phono inputs on the SS. Absolutely stumped now and I can't think of any other configuration to set it all up in so if anyone can shed any light that would be much appreciated. It seems to me I'm missing some sort of obscure setting somewhere but I really dont know. HELP!
