@Brad: Here is an update on this issue: Some People on the ArchLinux Forun[1] found a fix the cause. It seems there is a Workaround required (for this audio codec ALC1150) for the Intel PCHs but the device ids where missing. Until this fix is in ALSA (the kernel) the following module parameters fix this issue for me and others: options snd-hda-intel vid=8086 pid=8ca0 snoop=0
I simply created a modprobe.d file and reboot and now sound works! echo "options snd-hda-intel vid=8086 pid=8ca0 snoop=0" > sudo /etc/modprobe.d/fix-sound-intel97. I the forum, user Arthur who found the solution mentions there is a patch for the linux kernel, however i found no source or link to refer to yet but asked the user is there is something to provide us with. 1 https://bbs.archlinux.org/viewtopic.php?id=181764&p=2 ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1321421 Title: Sound output unusable with Intel Z97/H97 Chipsets and ALC1150 Audio Status in “linux” package in Ubuntu: Confirmed Bug description: I get horribly cracking sound and distortion with my ne AS Rock Fatal1ty H97 Performance Mainboard.
