Another update: I build the Vanilla 3.14 Kernel and removed the NVIDIA Graphics Card in an attemp to isolate the issue. No success so far. Actually it turns out the problem is not related to the NVIDIA Card. I get the same noise without the card installed.
It seems to get a bit better under high cpu load though.... strange? Any help would be appreciated. ** Attachment added: "Alsa-Info.sh output" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1321421/+attachment/4116532/+files/snd_hda_intel_kernel_3.14.0_default_options.log -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1321421 Title: Severly distorted Sound output with ALC1150 Sound Codec Status in “alsa-driver” package in Ubuntu: New Bug description: I get horribly cracking sound and distortion with my ne AS Rock Fatal1ty H97 Performance Mainboard.
