Windows 7 Windows 7 SP1 and 5.1 Surround Sound.

Hi All

I installed SP1 for windows 7 this week and since then my sound is not working propely. Its only playing my front 2 speakers (Not rear 2 or centre on 5.1s) I have installed new drivers (Realtek) but nothing.

Heres the wierd thing. If I run a sound test all speakers ding (on realtek or windows audio settings) Great but any application just pipes sound out to front 2 speakers. Is there another setting within windows ive missed?

I suppose stereo should only play on the front two speakers, but not completely sure. Using the Realtek HD Audio Manager, I suppose you have 5.1 selected and clicking on the speakers allows them to work, as you stated?

There does seem to be a "Speaker Fill" option you might try?

I cannot think of a reason why SP1 would effect your sound, unless some driver was changed.
