Hi all. I'm stumped.
I have a Zenbook UX31A, with a
non-OEM, clean install of Windows 7 (I've also experienced this problem on Windows 8). Actually, I'm dual-booting Ubuntu and Windows 7, but the problem only exists in Windows.
The problem: The sound works perfectly fine,
except for I get no sound from the headphone jack. The headphone jack
works fine in Ubuntu, so I know it's not a hardware issue (or my headphones). The speakers in the Windows volume control (in the taskbar) show audio playing when headphones are plugged in. If I unplug them, I get audio from the speakers.
The Realtek software detects that headphones are plugged in:

Thanks for the help.
P.S. Interesting how there is no official notebook forum on support.asus.com. Took me awhile to find this forum. Why?
