[Bug 1577288] Re: HDMI audio playback noise observed on AMD Polaris 10/11 GPU
Since , this test kernel doesn't have AMD GPU components for Polaris
10/11 built-in (please refer
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1577288/comments/8),
I cannot test the fix.
But, I suggest to include the fix in the release.
