Fix annoying high-pitched sound

November 28th, 2013 No comments

If you’re like me you’ve been suffering through a crazy high-pitched sound emanating from your laptop speakers. Apparently this is a common issue with certain types of audio devices. Thankfully via the power of the Internet I’ve been able to finally find a solution!

It turns out that the issue actually stems from some power saving features (of all things) in the Intel HDA driver. So I simply turned it off and guess what? It worked.

1) Open up (using root) /usr/lib/pm-utils/power.d/intel-audio-powersave

2) Replace or comment out the line:

INTEL_AUDIO_POWERSAVE=${INTEL_AUDIO_POWERSAVE:-true}

3) In its place put the line:

INTEL_AUDIO_POWERSAVE=false

4) Reboot

Hopefully this also works for you but if not check out the site I found the solution at for some additional tips/things to try.




I am currently running a variety of distributions, primarily Ubuntu 14.04.
Previously I was running KDE 4.3.3 on top of Fedora 11 (for the first experiment) and KDE 4.6.5 on top of Gentoo (for the second experiment).
