Bug Description
In newer Ubuntu 18.04 HWE kernels, it is possible for GPU HDA controllers to be dynamically runtime-suspended if the HDA's power/control mode is set to "auto". However, pm-utils explicitly sets this to "on" when resuming, which prevents runtime power management of these devices from working as intended.

pm-utils should not be used any more. Although it may be installed on systems that upgraded for older Ubuntu releases.
if auto is supported, it should set it to that, if that's the best known practice.
