PC comfy couch gaming setup is finally complete. Had to buy/download a bunch of shit to get it working as it should (and bought some unnecessary things along the way) but here's a brief summary of what people can do to get it up and running for cheap:
*HDMI cable. Duh. Need it for video, not so much sound.
*Asus Xonar U1. USB device that utilises some software magic to convert any game with multi-channel audio into a Dolby Digital signal. Most digital outs (except for high-end mobos) will only output a pure, uncompressed PCM signal and little more, unless it streams the digital data (from, say, a movie) across the port. This fucker has Dolby Digital Live which gets all sound signals (it's a sound card), regardless of speaker number/count, and puts it in a nice DD container for your amp to decode. So even if the game you're playing has surround out but only the surround that's via the 3x3.5mm ports, it'll convert that into a signal fer yer amp.
*USB repeater extension cable. For the Asus thingy.
*Extension thingy for HDMI. Because all mine were too short.
*Wireless KBAM. Initially thought I needed this, but seeing as I have a laptop, I found a free prog called:
*Synergy. This will basically let a particular PC be seen as a secondary monitor for your main one (but only mouse/keyboard sharing, no video. Maybe gamepads too). So now I can control my desktop with my laptop keyboard by just moving the cursor to the right and using the TV as the primary display. Still have the display duplicated with the desktop monitor, though.
*360 wired pad. Thankfully, have a cable long enough to reach the PC without it being inconvenient, though I'd wager you could also use the MS wireless dongle and a wireless pad.
So, there you have it. Shit, if I want I could even play a text adventure on my TV because I have my laptop right here. Comfy couching setup complete. Now just waiting for Valve to do their shit with Steam.
