Bug Description
[Description]
On a Dell Wyse 5070 ThinClient device with 18.04 installed, during cold boot and resume from S3, internal speaker will have a noticeable short pop noise.
[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:/
[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.
[HW info]
Codec: Realtek ALC3253
00:0e.0 Audio device [0403]: Intel Corporation Device [8086:3198] (rev 03)
Device is not with me at this moment, I will provide more info if required.
