--- Comment #4 from Manuel Amador (Rudd-O) <rud...@rudd-o.com> --- I don't think things further up the stack have the necessary information to make an informed decision. The "sound card" of HDMI outs and the video cards powering them appear as different PCI devices in many cases. Those layers up the stack also do not know how to report back to Powerdevil "well, the reason we are not shutting the screen off, is because HDMI audio is active", primarily because it is stuff like Powerdevil which is in charge of policy and setting the right DPMS configuration bits on the X server (I assume something similar happens in Wayland). However, if Powerdevil provided an inhibitor (class) that would explicitly inhibit DPMS — but nothing else, not the screensaver, not screenlock in the screensaver, not suspend, not hibernate — then a plugin at the PulseAudio level of the stack can talk to Powerdevil and use that inhibitor class whenever there is an active HDMI audio stream, which is something that PulseAudio is perfectly positioned to know about. -- You are receiving this mail because: You are the assignee for the bug.
