====== How To Avoid Popping Sound over HDMI in Windows ======

Originally from: [[https://www.tenforums.com/sound-audio/12589-windows-10-popping-sound-speakers-4.html|this forum post]], I found this link to [[https://docs.microsoft.com/en-us/windows-hardware/drivers/audio/audio-device-class-inactivity-timer-implementation|docs.microsoft.com]] detailing how to find the appropriate registry key that disables power management for the audio driver.  I searched in regedit for PerformanceIdleTime, then set 'IdlePowerState' to 0, the popping stopped.
