Thanks a lot!!
I’ve been finding the solution to this crappy sound card problem.
It’s so sad that Apple didn’t improve this.

What? Macs aren’t perfect?

You just potentially cost Apple money

Well, leaving the audio subsystem on isn’t particularly battery-draining (my own assumption). WIthout this fix, the subsystem would probably go to sleep but unless the audio is muted, there will most likely be a sound played which will awaken it.

To tell you the truth, I don’t think that it makes any difference. If you’re that concerned about battery life, then I suggest muting your sound and leave Antipop at its default setting (disabled on battery)

As far as I can tell it doesn’t affect battery life substantially. I opted to disable it when not on AC power by default merely as a precaution, but I’ve enabled it for use when my MacBook’s on battery power and I haven’t noticed any significant reduction of its battery life.

The “very silent pop” that the author mentions is indeed a separate issue. The MacBook’s audio system sometimes generates a buzzing, popping or whining noise when idle (i.e. powered, but not playing anything.) My guess is that this is caused by poor filtering.

This is an interesting work around, but wouldn’t it also mean that — since you’re keeping the audio subsystem from ever shutting down — this negatively impacts battery life?

You’ve covered processor usage, but I would be very interested to know what the difference in battery life is when using antipop.
