Sound Drivers For 7

so you using analogue then does the control panel for it have something along the line of jack auto sensing does it detect when a plug have been inserted or removed

No it doesn't, it's nothing fancy tbh.

Just 3 jacks input, and the speaker outputs.

you mean the sound card right have you set the windows speaker config to 5.1

If i set it up like that, it gives me a terrible echo or something..
All speakers do work though.

It is in dutch, but I asume you understand it.
The bottom icon should be the sound card, but I can't go into speaker setup on that one.
The top one I can set up, but it gives me the echo
Attachment 4802

hmmm sounds like either your plugging into a Mic input instead of an speaker output or you have a Mic plugged in and not muted

so the speakers are plugged into these sockets then
lime = front speaker out
orange = center/sub out
black = rear speaker out
gray= side speaker out

All jacks are plugged in properly, and I don't have a mic.
Tried to fix it with the settings, but it echo's when I set it to 5.1 aswell as stereo.

did it come with a driver CD or did you D/L theses

back in that sound control panel you had opened instead of clicking Configuration can click Properties on the right and select the System Effects Tab and turn off all system effects ans see if that helps

I do have the program installed, but it says nothing on any systems..
Now I got to the point where it doesn't echo anymore, but it doesn't give me true 5.1 either.
I do here some crackling sounds through the 2 rear speakers, somewhat sounding like the music.

frankly I'm not really surprised that this isn't working as advertised seeing as the driver download from the above post is an old driver from 2003 I'd be more inclined to tell you to take it back and tell them it doesn't work properly under windows 7 x86 32bit and see if they have an SoundBlaster Audigy 2 or better as these work just fine in windows 7 with the driver provided by Microsoft and when talking to them ask them about windows 7 compatibility

That is possible, but the problem is I don't feel like spending 50-60 euro's on a soundcard..
