A current audio driver REALTEK R275 6.0.1.7246 is buggy, seems to fail to sense headphones plugged into headphone jack after computer restart. You have to replug headphones every time you restart your computer.
If you are not using headphones or external speakers plugged into this output, then you can install this driver as it works fine on all other functions, but if you would like to use headphones, then better install any other earlier Realtek version that doesn’t have this bug.
