Solved Realtek High Definition Audio and Intel Display Audio

[jim97219]

I think my question is this: how do I set up VSX-1124 (a Pioneer AVR) in Control Panel/Sound and Hardware/Sound so that its driver is Realtek HD Audio and not the Intel Display Audio one?

In Device Manager under Sound, Video and game controllers, I have two sound card drivers, Realtek High Definition and Intel Display Audio. I don't understand how Realtek High Definition Audio drivers work in relation to the Intel Display Audio drivers. If I go to Control Panel/Hardware and Sound/Sound then Playback, there are four options, as you can see from the picture below.

I'm guessing that if I choose the receiver as my default device that I'm using the Intel Display Audio drivers and any of the other three options that I'm using the Realtek drivers. Is this correct? If the receiver is the default device, everything works fine; I get sound from sites like cnn.com and I can listen to internet radio, etc. However, if Speakers are the default device, I don't get sound. Is this normal? If so, what's the reason for having Realtek? If it isn't normal, will I notice a difference if I use the Realtek drivers? If I would see/hear a difference, how do I get them to work?

The RealTek is for the regular PC sound. The Intel Display Audio is for HDMI sound. If an HDMI cable is plugged in Windows will automatically default to the HDMI as the "default playback device". If you have an HDMI cable plugged in and want the PC sound you must manually change the playback device. If you want both HDMI and PC audio, you can't have that as Windows will only allow one default audio playback device.

Does this answer the question?

Yes, it does answer my question. I do have the PC connected to the receiver only via HDMI so the RealTek drivers are basically worthless unless I connect the PC to the receiver using the jacks in the back of the two units. Somehow, I had the idea that the RealTek driver could be used instead of the Intel one and that it would somehow be a better way to go.

I most appreciate your great explanation.
