I have a Sony Bravia LCD TV and a Sony HI-FI stereo system. The thing is my TV's HDMI ports do not work anymore and to connect HDMI devices, I connected a VGA cable to the TV and used a HDMI to VGA Adapter and further used a HDMI switch to connect my three HDMI based devices. My Set-top-box is connected to the hi-fi system and when the Hi-fi system turns on, so does the box and its connected via AV since the hifi doesn't have a HDMI port. I want to get sound of whatever i connect on the hdmi switch through the hi-fi system. My Tv has a digital audio out port and so does the hifi system, if i just get a cable, would that do it? Because the vga to hdmi adapter has an aux port and i used an RCA but it didn't work. I can disconnect the set top box from the hifi system and connect it to the tv but i want that sound should come for anything i connect on the hdmi switch. Will a digital output cable work? Or is there some other workaround?
