No the HD 3000 is a video chip and you would have to get sound from the motherboards built in HD sound chip. There is most likely an option in the bios to activate the MB sound chip and then the install disc for the MB would have the drivers for it.
Have you gone into the bios to make sure that the settings are ok with the sound device active.
Did you go into device manager to make sure that the sound device is enabled and active.
Did you go into the control panel to make sure that the MB sound device is the one that is selected to do playback and that the other optionas are all active and the sound device is selected for all of them.
The HD3000 IGP does support HDMI and DisplayPort sound, no need for motherboard audio in that case but some extra fiddling with drivers and output device configuration to make players output to the correct devices may be required.
Yea i was thinking about that but the HD3000's sound capabilities aren't ever used as manufacturers put another sound chip on the mobo (Realtek most of the time).
The reason motherboard manufacturers put sound chips on motherboards is because people are not interested in running a HDMI or DP cable from IGP to HDMI/DP AV receiver just for sound in a typical desktop setup on top of the cable from GPU card to display... or running analog cables from the display to the AV receiver.
In a living room environment with AV receiver or direct-to-TV connection scenario though (as appears to be the OP's case), it makes perfect sense since it eliminates cable clutter and analog audio between the PC and receiver/TV.
