Hi guys,

I was wondering if i could get some advice/tips.

I'm trying to get my 5.1 speakers (logitech G51) to work 'fully' with my laptop (HP TM2), but hitting a slight logistical problem in that the speakers have three output jacks, and my laptop only has one input.

Now, Ive done some googling and reading up on this, and one source suggested this adapter:

 and buying a 3.5 male to 2*RCA male cable.

In terms of the physical getting-three-plugs-into-one-jack, it seems like it would work. Any thoughts or comments on whether the signal would actually get through?

Secondly, i understand this wouldnt be "true 5.1", as Im not using a 5.1 capable sound card. Considering the only way to get "true 5.1" on a laptop would be to buy a USB-based sound card.... would this be a better option for things like watching blu-rays (which have a 5.1 soundtrack)....

If I go with the first option, will it just be 5 speakers (and a subwoofer) plonking out the same audio...i.e stereo but with 5 speakers instead of 2.... meaning all I get out of having "5.1" is more volume and less directionality?

Hope that makes sense, as Im kinda new to anything that is not stereo.

Any advice/corrections much appreciated. If both options work, wahts the pros/cons of each option?

You are correct. You wont get true 5.1, just stereo x2 - it will sound awefull. Get a USB sound card would be my advise.

When you live your life on Twitter and Facebook, and are only friends with like minded people on Twitter and Facebook, you are not living in the real world. You are living in a narcissistic echo chamber.


My thoughts are my own and are in no way representative of my employer.

Have you tried the speakers just using one jack? I have some cheap logitech 5.1speakers and I use them just with the green plug. It sends the sound to all 5 speakers fine.

If its the Logitech 5.1 Set.

Use the Adapter from 3 3.5mm Jacks to 2 RCA.

Then 2RCA to 1 3.5mm Jack. That way all your speakers will work.

Or Get a external Sound Card
