My new motherboard is an MSI X470 Gaming Pro Carbon. I built the rig myself and it's working good except for one minor thing. When I start the PC I don't hear the single "short beep" when it boots. I checked the board and found the speaker connected to the connector. Assuming that perhaps the speaker was defective, I purchased a new one and installed it but still no "single beep". The board has a UEFI AMI Bios. Any idea why?
