A non-computer question from the lady who didn't know what an AC Adapter was...
I'm hoping to learn how to make music by recording and layering on, either myself with myself, or myself with my trio buddies. I'm getting good info about mics, but I also would like to play my recordings on my good speakers, currently hooked up to the TV and cable box. But it's a nightmare. In the picture below, the red and white connections at the bottom go to the cable box, and the ones on the right go to the TV. I've hooked up a tiny speaker to my computer, so I know it doesn't us a double wire (although, interestingly, there seem to be 3 little holes to plug the speaker in, and it doesn't seem to matter which I use.
Is it possible to hook my computer up to my receiver that's connected to the good speakers?
If yes, what kind of wire would I need (specific name for searching Amazon and eBay, please)
Where would I plug the wire into the receiver?
Does it matter that the recording is made on the computer, assuming I use a good external mic?
Thanks much in advance,
LAS

... I can now play the music files on my computer through my really good speakers. Thanks for the explanation about where I would "select"
