For those of you that use a Windows laptop and the built-in sound card for audio work, you may have experienced a very irritating feature, power management.
When no audio is being played, after 10 – 30 seconds (depending on settings, model, etc),
you will hear a loud, distracting “pop” noise as the sound card is powered down.
Same as when you then start playing audio again, which triggers the sound card “back to life”.
Some drivers would allow this power management feature to be disabled via the settings GUI. However, this now seems to be a thing of the past for most.
