I guess I need to join in here too. Though my problem is slightly different. According to all the info I have available - I have the correct drivers installed and when I do tests - the meters show sound is being produced by the soundchip. However nothing is being heard. Like those above its an onboard realtek hd soundchip. It works perfectly well under XP (this is a dual boot pc), but is deathly silent under 7. Motherboard info should be on my profile but its a foxconn.
