I have an ASUS K53SD with a dual boot Archlinux/Windows 7 x64. Everything worked fine with audio until last week when I realize that my Jack output doesn't work anymore on windows while it still works on linux...
I tried to reinstall realtek driver but the problem is still the same, when I plug the jack a popup say "Jack inserted", speakers are muted but I have no sound in my headphones.
Any idea ?
