Eureka moment: I've had my dad's old hi-fi system for quite a while now, but haven't had any speakers to use with it. For the longest time, I've simply watched OTA TV through the TV's built-in speakers while my PC-based content gets the advantage of my (quite good) desktop speakers. Going through a box of stuff from home, I found my collection of audio jack adapters: Now I've got enough cables/adapters to connect everything to the hi-fi, and I can use the 1/8" headphone jack output for my desktop speakers! Just in time for the olympics too :-)
