Summary0007412: Upstream bug in alsa.
DescriptionI have a ASUS Z97 Motherboard. The on-board sound is using snd_hda_intel driver. Output to speakers crackles every-time.
Steps To ReproduceInstall OS, attempt to output sound to an attached speaker.
Additional InformationAs highlighted on various Debian based forums, this is a bug in Alsa and the ALC1150 chipset. The work around is to pass snoop=0 to the driver. So I created /etc/modprobe.d/fix-sound-intel.conf with:
options snd-hda-intel snoop=0

I include this for other people I guess.
