Yes I am using the realtec sound.
I selected the 2CH option under the speaker conifuration tab.
I put the connecter in the green slot and it says thats connected correctly but seems to have something else it expects to connect in the 'line in' it seems which is the blue slot.
Any ideas on this?
EDIT: And yes these are the first speakers with this computer. I fear that maybe I do not know about the speaker configuration or sound cards. I bought the computer from the following option: (well very similar, I managed to get a few parts not listed in the upgrade part)
Soundcard 7.1 on board - 8 channel
That seems to be the sound card, does thi affect anything?
