[More detail] There are similar bugs reported indicating it's related to codec powersaving [1]. On some devices, disable powersaving can workaround it, but the same workaround does not work on this device. [1] https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1821663 [Experiment] With Ubuntu 16.04 (4.13 kernel) installed --> NO pop noise With Ubuntu 16.04.x (4.15 kernel) installed --> pop noise With Ubuntu 18.04.x (4.15, 5.0 kernel) installed --> pop noise So I started testing kernels between 4.13 and 4.15, found the issue does not present before 4.15.0-58 kernel (including 4.15.0-58), and kernel after that started to have the pop noise.
