30 seconds after sound ends, I hear snap or pop in the headphones

[OmegaRace]

Hello,

With my MBP 2010 15", 30 seconds after sound ends while using my headphones (either of two pairs), I hear a pop or snap in the headphones. This happens after playing Youtube, or after using mplayer in Terminal. I haven't used iTunes extensively so I can't say whether it happens with that app.

This does not happen under Windows 7 at all, which I have installed in my Boot Camp partition.

I did a little google searching and it seems people say this occurs because the OS turns off the sound card to save power, but does so in a very ungraceful way. Another person reported that they had no problem under Windows XP but did see this problem on multiple Mac laptops.

One person back in 2008 said they found a utility that tricks the OS into thinking that the sound card is always playing audio, so the power-off and therefore pop or snap sound no longer occur, but that utility seems to be a PPC-only binary & anyway I hate running unofficial utilities.

Does anybody here know if there is another way to fix this problem?

I suppose I could write a Bash script that plays an all-zeroes wave file every 25 seconds, but that would be a kludge.

Thanks.

As far as I understand it, that's correct. The same thing happens on the iDevices.

You say that you don't like unofficial utilities but then talk about writing a script?

Anyway, there isn't an official solution.

This seems to happen when I use low impedance headphones. I've noticed it doesn't happen when I put an in line adapter that came with them for volume control and add impedance.

Yes, I have two pairs of headphones & it happens with both.
