Acer Predator x34 Audio Issue

[JadeGames]

I recently got my new acer x34. I haven't found any problems with it yet accept for the squealing sound every time I put my computer in sleep mode. I've only just found tis issue but its very worrying. Could it be my system? Is the monitor defective? I rebooted my computer after hearing the sound and tested the speakers on the monitor and they were fine.

If you get that sound and say unplug the monitor from the wall does it go away (even if after a few seconds)?
