*bangs head against wall* Guys...lend me your ears. Or if you don't have functional ears, lend me your hearing dogs. We bought my father an XBox 360 (slim, 4gb, wireless version) for his birthday today. Knowing beforehand that he would want to use it with his computer monitor (as he already has two monitors set up in his gaming pad) we also went ahead and bought this cable. We set up the Xbox this morning, running the video through the VGA port and the sound through the red/white + jack into the line-in. And lo, there was video. ...And no sound. After swearing quite a bit and using several techniques found via Google and YouTube, we've hit a total brick wall. Firstly, we tried the trick of running the Xbox -> audio line-in cable into the back of his sound card, then plugging a (working) pair of speakers into the line-out, and making sure that Windows was running in the background with the line-in unmuted. Didn't work. We then tried just running the line-in directly into his speaker's headphone port, and there was still no sound. So then we brought the Xbox downstairs and plugged it into the telly via the Xbox -> red/white/yellow -> scart adaptor cable the Xbox is provided with, and everything was fine. We had audio and video, and mucked around on the Orange Box a little before sobering up. The problem, as far as I can see, would be in one of three separate components: 1. The monitor speakers are broken. We tried running a direct line from the computer to the monitor directly, and we had no sound. But I don't know if that was because the old cable Dad found was also borked. 2. The red/white -> audio line-in adaptor the cable linked above came with is broken. 3. The entire audio side head of the cable linked above is broken, as the VGA works fine. Please, if you have any ideas/suggestions, I'd love to hear 'em. We can't keep the Xbox plugged in down here, and Dad is desperate to get crackin' on some Portal 2. Thanks in advance for your time/help!
