I'm thinking of getting a mac mini, which only supports 5.1 sound using its optical connector. My speakers don't take optical audio - just six channels of analog audio. I'd like to ask how to get around that, but it doesn't seem to fit on serverfault, stackoverflow or superuser. Where would I ask about home audio setup?
Sound Design Mod Edit This answer is no longer correct (hasn't been for over 6 years) - consumer audio is explicitly off topic on Sound Design
For future reference, you can now ask these kind of questions on the Audio Recording and Production StackExchange site.
Audio Recording and Production has been merged into Sound Design.
