Ok, so I’m seriously not good with computers and the likes so heres the deal…
If you have a motherboard that says it has 6 channel sound…it will play 2.1 speakers right?
but how does it work??
Does it need a hole for each speaker on the back??
Thanks
If you want to use 2.1 only, attach you headphone jack in the green hole. The coloured holes are for 5.1/6.1/7.1, and the pink one is generally the mic. Your motherboard manual should explain most of it 
First of all 2.1 means … 1 woofer with 2 speakers. where as speakers are connected with the woofer and woofer is connected with your computer.
What is 6 Channel Audio ?
There is a myth about 6 channel audio, what it is and what it does. A lot of people get confused between 6 channel audio and 3D surround codecs. 6 channel audio is not Dolby 5.1, or EAX or A3D. 6 channel audio means that the sound card can produce sound on six different channels - 2 front, 2 rear, one sub and one center. It is up to software applications to utilize all 6 channels. If the application you are using only supports 2 channels and a center - that’s all you’ll get. By default, most speakers with a sub will automatically use the sub when 2 front channels are being used. To be able to use 6 channels correctly you need a set of 5.1 speakers. You cannot use two separate sets of speakers and expect to get 5.1. It doesn’t work like that.
And remaining is according to the Merlin…
