I have a 2.1 self-powered speaker set made by Creative that I bought to play music on my laptop. Input is mini-jack. I would like to connect them to the blu-ray player I just got. Audio out on the blu-ray is RCA. I got an adapter with two RCAs on one side and a mini-jack on the other and connected the blu-ray player to the speakers. But I only get sound out of one of the speakers (plus the woofer). Is there a way I can kluge this up, or do I need to buy new speakers and a receiver?

Two RCA plugs to stereo mini-plug is the usual stereo connecting cable for this application.
1. Make sure you are plugged in all the way.
2. Try another cord, or ring out the cord with an Ohmmeter.
3. Check the setup on the BD player.
4. Try the Creative speakers on another source.
5. Try the BD player on a TV.

Thanks very much for the help. I did everything you said:

1. Plugged in well: check.
2. Rung out cord: Both RCA prongs are connected to miniplug tip, both outer RCA electrodes to miniplug shaft.
3. BD Setup ok, I think.
4. Speakers work fine when connected to laptop.
5. Audio plays correctly when BD connected to TV via RCA.

I think I have the wrong adapter (thanks Radio Shack). I didn't notice before that the miniplug end of the adapter only has 2 contacts, while the cord I use to connect to the headphone jack of my laptop has 3. I am completely ignorant as to how the stereo information is encoded, but it seems to me that tying the left and right speaker outputs together negates the "stereo" idea. I will try to find an adapter that has 3 contacts on the mini plug end and doesn't tie the two RCA prongs together.

Thanks again for your help. If I'm on the wrong track, please post to say so. Otherwise, it's back to Radio Shack asap.

Yes, it was number 2 where you found the problem. Patch cord should be using a tip-ring-sleeve miniplug. One RCA plug goes to the tip, one RCA plug goes to the ring, and the RCA shield connections go to the sleeve of the miniplug.

Yes, you have a mono 3.5mm to stereo rca adapter. This is designed to send the same signal from a 3.5mm source to both channels on a stereo. You are correct that you need three 'rings' on your 3.5mm end. One for ground and one for left, one for right. Here is a picture at monoprice: http://images.monoprice.com/productlargeimages/6652.jpg
