Windows 7: Internal speakers not working but headphones are fine

I have just done a fresh install from vista to Windows 7 7100. All drivers are installed and working fine but I dont seem to be getting any sound out of my internal laptop speakers.

I plugged in headphones and they work fine, i never had a problem in Vista.



I have install the latest Realtek 223 codecs and still no joy, I'm in the middle of trying some older versions but does anyone else have any ideas?

I'm running:
Windows 7 RC7100
Asus M50Sv
Realtek 223 codec

Not to sure on the accual hardware model.
Thanks.

Sounds like an assignment problem;
Realtek HD Changing Jack output reassignments ( FIX )

I don't really understand, how do i know what assingment the internal speakers are using? And what assignment is for that pin?

I have tried 4 older versions of the Realtek drivers without any succues. I'm open to ideas.

Did you manage to fix this? I have an m50sv and it seems to be working fine on mine...
You may have to reinstall Win 7 if it still isn't cooperating
