So here's what I got. Feeding with proscan no problems. My PC goes to a HDMI output to a splitter. I can select between a cable tv box or the PC. It seems weird when I deselect the PC to the monitor as the feed continues the sound of the feed comes out of the motherboard small speaker? The beep speaker I call it. When I select the PC to the monitor at the hdmi splitter it stops doing that? Anyone know how to mute the motherboard beep speaker?

The PC is probably flip flopping audio output sources. I'd assume the PC is selecting the monitor's speakers when it's selected, and reverting back to the PC speakers when the monitor is set to the TV.

All you need to do is select the PC speakers in Windows, and mute them. Then when the PC reverts back to them, they will be muted.

I could use some help here, I went to system properties system sounds muted and still I get feed noise over the mb speaker?
Nevermind I figured it out. A little more digging in settings I found to disable realtek speakers.
