[arch-general] Headphone Sound Trouble

[Heiko Becker]

Hello everyone,

since some days I am experiencing strange issues with my laptop 
headphone jack.

When I boot into Windows 8.1, everything works as expected. No problems 
or cracking sounds.

When I boot my Arch installation, it seems like everything breaks.
  My headphones randomly produce loud cracking sounds and when I manage 
to get something out of them, the sound is blurred and sounds disturbed.

Searching the Asus FAQ's gave me:

https://www.asus.com/en/support/FAQ/1009646

But I do not know how to check for these settings and wether this 
applies to me.


Some system information:

Hardware: Asus N550 JK Laptop
