Hi guys, i have just installed vista ultimate on my custom build pc. All the drivers are listed in device manager but there is no sound from speakers. When i play a song, it shows that its playing but no sound. Also, when i check in playback devices tab, it shows that i have High Definition Audio Device but when i check in the recording tab, it shows No audio Device Installed. I also downloaded driver from intel but didn't work. Its Intel 945 Desktop motherboard.
