Here's a little trick I've just found to avoid noise, if you connect one of your integrated outputs to an amplifier.
It might only work in specific cases, but here it is anyway.
My issue was that after 15 to 30s of inactivity a buzz would rise in my speakers (nothing on headphones) and stopped (with a cracking sound) when I clicked anywhere in a window or typing on the keyboard! And it was worse when connecting the audio with a long cable... None of the tricks I've read were working (changing Sys Def, etc.)
Probably buying a ground loop isolator or ferrite bead could resolve the issue, but in the meantime I analyzed what seems to happen: looks like our AppleHDAs are releasing their grip on the physical outputs after some inactivity (I noticed the issue was already there at startup even before BIOS).
So I used a white noise generator, setting the level as low as possible (I achieved -80 dB), in this way, the audio interface is always fed with audio, so low that you can't hear it and the "disconnection" never happens.
Here's one freeware that does the trick, you just have to add it to your startup items (noise generation autostarts if it was active when you last quit the app)

Of course, if you always have audio running thru your output, this is totally useless.
