Describe the bug
Reported in #195 #34 #14

Most likely because the audio engine is running even when there's no audio playing and is still pumping sound (even though it's silent) the Mac thinks there's still some audio playing. But need to look into it a lot more.

Expected behaviour
If settings are set for the Mac to go to sleep after X amount of minutes, when there's nothing playing audio the Mac should go to sleep mode.

I have done a bunch of testing and for me it seems to work as intended. If there's no audio playing then my laptop goes into sleep in 1 minute as set in settings here:

I will test with audio playing and report back.
Would be helpful if people posted their Sleep settings and what state their machine is at the moment it should go to sleep (playing audio/video, device running audio through etc.)

Thanks for looking into this. Loving eqMac! I think the issue happens only when audio is routed to HDMI or DisplayPort device. My laptop is connected via HDMI to my Dell monitor which is where my speakers are connected to. I was using Soundflower previously which had the same issue.

Thanks for looking into this too. I have same environment with @DesmondKong.
My laptop is connected via DP to main monitor.

I can confirm that this not only prevents the system from sleeping, it also prevents the display from turning off (both the laptop screen and my external monitor). I've been having this happen recently but not 100% of the time, and I think I've tracked it down to using DisplayPort audio with eqMac. If I switch eqMac to Internal Speakers, the display does sleep properly. pmset -g reflects this:

_(This is with my MacBook Air on AC power; values are different on battery but still preventing display sleep. I mainly use eqMac when connected to the external monitor, so I can control the DP audio volume. The Dell 2408WFP likes to clip when the audio is too "hot", which sounds terrible, and it's also more convenient to use the volume up/down keys rather than the volume control on my speakers.)_

If I switch eqMac to internal speakers, the "display sleep prevented" message goes away. I have to quit eqMac entirely to remove the two coreaudiod processes from the "sleep prevented" message, but I'm more concerned with display sleeping.

Note that using DP audio without eqMac only prevents the display sleeping when audio is playing, but when nothing is active, the monitor will go into power-save. E.g. playing a YouTube video shows displaysleep 10 (display sleep prevented by com.apple.WebKit.WebContent, coreaudiod) in pmset; pause it and the webkit entry goes away, and a few seconds later, so does coreaudiod. Looks like eqMac is always holding open an audio stream, which causes coreaudiod to keep the DP audio device active, preventing display sleep?

I am having the same issue.

Also, in my case, eqMac is constantly having current energy impact of >3 even when there is no sound output / nothing is playing.

Same here, connected via DP to an LG monitor with speakers. MacOS is unable to go to sleep when eqmac is opened.

On DisplayPort audio, my mac won't go to sleep.

Same issue with hdmi :( no fixes?

Hi. To reduce duplicate entries I would like to report I am experiencing similar issues.

pmset -g reveals
coreaudiod, coreaudiod are preventing sleep.

pmset -g assertions reveal:
pid 335(coreaudiod): [0x000005a00001812e] 00:23:22 PreventUserIdleSystemSleep named: "com.apple.audio.EQMDevice.context.preventuseridlesleep"
Created for PID: 654.
pid 335(coreaudiod): [0x000005a000018126] 00:23:22 PreventUserIdleSystemSleep named: "com.apple.audio.AppleHDAEngineOutput:1B,0,1,1:0.context.preventuseridlesleep"

I initially checked Activity Monitor and I have a sample taken if you'd like me to send it?

eqMac is set to internal speakers. Quitting and restarting the app displays a Yes under Preventing Sleep on Activity Monitor.

Hope this is of some help.

Thanks for everything you do. Since discovering the app it has changed how I listen to music.
