Built a new system from scratch. MOBO didn't have an onboard beep speaker but had pins for a small 4 pin 2 wire connector. No case speaker. Plugged in a small Rhino internal speaker observing the correct polarity. It beeped on boot but you could only hear it with the case cover off or if you had a "steth-a-scope" . It was very low in volume. I have racked my brain researching how to turn up the volume but hit one dead end after another. MOBO Gagabyte GA-Z77-D3H (rev. 1.1) with no means of adjustment. Any suggestions/help will be greatly applreciated. Thank you.
