I think you mean this setting:

The number of seconds of inactivity before the session is considered
idle.
Yeah, I guess I could use that to disable the screen saver, but was
thinking about something that would work automatically and inhibit it
only when the music is playing through HDMI for example.
No, I meant the setting in the screensaver itself. It separates into
three timers under 'Display Power Management':
Standby after xxx minutes
Suspend after xxx minutes
Off after xxx minutes
But, I see now that it is Xscreensaver, and in Gnome you will be using
Wayland. Also, it doesn't meet your requirement that it happen only
when the display is being used. So, it wouldn't meet your needs, and,
as Rex said, you need to somehow gain that ability for your application.
