Okay I need some ideas. Firstly, this is a work computer and I do not have admin privileges. Second I'm doing this solely for my convenience.

We have a Dell Latitude 3540 and I'm running a generic second monitor that we happend to have around. We do not have a docking station, so we're using a spare Samsung K550 Soundbar to upscale the resolution on the second monitor through the ARC TV HDMI port. So it's, HDMI out from the laptop to the sound bar and then ARC HDMI out to the monitor. The issue, the sound bar goes to sleep after 5 minutes of no sound and I can't disable the auto off feature. This shuts off the feed to the second monitor and it doesn't resume automatically. I think if I can find some kind of timer that will send some sort of sound to the bar every 4 1/2 minutes or so, then it will stay active. I don't know how to do this. Does anyone have suggestions? TIA Tug

What if you played some ultrasound? You can't hear it and the speaker is being used.
