I am running Windows XP Professional on partition 1. There is no problem with the sound.
I recently installed Windows 7 Ultimate 64Bit on partition 2 and use the dual boot feature, which is working fine. However, I cannot get sound.
In Realtek HD Audio Manager all speakers test well.
In the Sound Applet in control panel, speakers is the default device and the test produces sound tones in all speakers.
Yet, I cannot get startup or exit sounds in Windows, and there is no sound when playing movies, cd music, or watching video on the internet.
I downloaded the latest driver
from Realtek dated 12/25/09 version 184.108.40.20613.
There is still no sound except for the test tones.
I did an uninstall and re-install and no sound. I tried different driver versions and still no sound.
On another computer I am running Windows XP Professional and Windows 7 Ultimate 32 Bit in a dual boot configuration with no sound problems in either operating system.
Is there a problem with the 64 bit drivers
Can anyone help?
