Describe the bug
When eqMac is enabled, the PreventUserIdleDisplaySleep assertion is raised, regardless of any output. This prevents a screensaver from activating and consequently having the screen lock and sleep.

   pid 2244(coreaudiod): [0x0015161d00058e2c] 00:00:02 PreventUserIdleDisplaySleep named: "com.apple.audio.AppleGFXHDAEngineOutputDP:f803:2:{F005-069E-00000000}.context.preventuseridledisplaysleep"  
	Created for PID: 37780. 
	Resources: audio-out AppleGFXHDAEngineOutputDP:f803:2:{F005-069E-00000000} 

Steps to Reproduce
Steps to reproduce the behaviour (feel free to change the placeholder as you need):

1. Enable eqMac
2. run "pmset -g assertions" - you'll see that the eqMac PID has caused the assertion to be created via coreaudiod
3. wait however long you want - the display won't sleep

Expected behaviour
eqMac should not raise this assertion unless there is audio output occurring.
