Title:
HDMI audio makes loud popping noises while playing audio
Status in linux package in Ubuntu:
Expired
Bug description:
When playing audio via HDMI, I get very loud pops and/or periods of
silence. The frequency of this behaviour seems to go way up while
playing video with a lot of motion, and especially YouTube videos. I
can reliably reproduce the problem by playing the video
https://www.youtube.com/watch?v=vt9UZo32KMk and maximising/minimising
the video size rapidly.
Testing older kernels, I can reproduce the problem on the linux-
image-4.10.0-041000rc1-generic from http://kernel.ubuntu.com/~kernel-
ppa/mainline/, but the previous version, linux-
image-4.9.71-040971-generic, plays audio without any problems.
The problem didn't exist on 17.04; it only started happening after I
upgraded to 17.10. (I know 17.04 had a 4.10 kernel; I'm at a loss to
explain the difference unless the zesty kernel was patched.)
