I have a similar problem with the ASRock Z97 Extreme4 - http://www.asrock.com/mb/Intel/Z97%20Extreme4/
Running virtualbox windows instance the sound is better, but not 100% Also the sound is almost usable watching a youtube video, but switching to another tab with the video playing is horrid. I have tried the above hacks with the /etc/modprobe.d/fix-sound-intel97 file, but it does not make a difference. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1321421 Title: 8086:8ca0 Sound output distorted/unusable with Intel Z97/H97 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1321421/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
