In my Windows 7 beta I cannot get the 5.1 surround sound to work properly. I have an integrated realtek hd chip (which works perfectly fine in Vista). The 5.1 sound works well when testing the sound in the windows sound settings but whenever I try some other playback (wmp or whatever) only the front left speaker works.
I have also tried installing latest drivers
from Realtek (5.1 works in their sound control aswell), some older drivers and of course the standard windows driver
, all with the same results.
Any solutions or hint available out there? Thanks.
