Does it occur with all applications? For example, I have crackling sound with headphones in all ALSA applications such as unpatched wine, but not in e.g. a patched wine-staging or VLC or most Linux games because they use Pulseaudio.
For testing purpose the OP could build a package using
pkgname=pulseaudio pkgver=2015.05.10 pkgrel=1 pkgdesc="Dummy package" arch=('any') provides=('pulseaudio')
for a PKGBUILD, install the package, to 'definitively disable' PA.
I don't allow PA being installed on my machine.

Unlikely that ALSA is the culprit, since PA does use ALSA.

So in fact I do not have Pulseaudio installed, hence it cannot be the culprit :D Nevertheless, when trying to test based on the instructions given before (aplay for the wav files) I was also able to reproduce the issue in awesome WM too. But when I boot into Windows 8, sound is crystal clear and nothing cracks. Related to the driver stuff: I installed bumblebee some weeks ago and do not remember having used any audio player since then. Could it be the case, that bumblebee or something related is the culprit? Is there an easy way to rule out that it is a hardware bug? Regards, -- Heiko
