I upgraded my laptop to Windows 10 a while back then did a clean install of Windows 10. Since then, I can't get any sound to play through the built-in laptop speakers.
I've tried uninstalling and reinstalling the Realtek audio drivers but it hasn't changed anything. The speakers are set to default, and when I open Playback Devices, I can see the audio meter next to the Speakers device jumping up and down, but there is no sound playing. The only other device is the Realtek Digital Output.
If I plug headphones into the audio jack, they work fine. The only reason I know my speakers still work at all is that I can enable an option in BIOS that causes a tune to play when the computer starts (not the normal POST beep), and it plays through the speakers.
It's almost like the audio output is always being redirected to the 3.5mm audio out, whether headphones are plugged in or not.
It's an Asus N55SL laptop.
