Public bug reported: Problems with the sound (chipset z97). I've got the sound in Windows - so it is a software bug. Freshly installed default system. First time this was Kubuntu 14.04 then it was upgraded to 14.10 for a fresh kernel. No effect to the problem. Found the similar problems here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1321421, but none of the workarounds helped me. Upgrading to the 3.17 kernel dind't help.
