📎 AI Summary:
The thread discusses a Windows 7 issue where, after installing SP1, sound only plays through the front two speakers of a 5.1 setup, despite testing indicating all speakers are functioning. The original poster queries whether a Windows setting might be causing this problem, noting that sound tests work correctly. A responder suggests verifying the speaker configuration in Realtek HD Audio Manager and mentions trying the "Speaker Fill" option, but concludes that SP1 is unlikely to be the cause, and the issue may relate to driver or configuration settings. Overall, the sentiment indicates a troubleshooting process aimed at resolving speaker configuration issues post-SP1 update.

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.
