Public bug reported:
This bug is meant for tracking purposes. Please do not triage.
On shutdown/reboot of CX20722, first shut down all EAPDs, then
shut down the afg node to D3.
Failure to do so can lead to spurious noises from the internal speaker
directly after reboot (and before the codec is reinitialized again, such as in
BIOS setup or GRUB menus).
