Asked by plc1127 on 2009-10-31

Hi Everyone,

I am having problems with Ubuntu 9.1.. since the upgrade, I get this white noise through my laptop speakers. It goes away when I play music or video, but it comes back about 30 sec. after the music stops.. I have tried everything I know and all options in sound preference including just turning the hardware off, and it doesnt work... its quite annoying. Please help

This is most probably the audio power saving mode kicking in and causing clicks/pops when the audio hardware is transitioning to a low power mode.

To disable the power saving mode using snd-hda-intel edit /etc/modprobe.d/modprobe.conf (e.g. use sudo gedit to edit this file) and add the following line:

options snd-hda-intel power_save=0

reboot and see if this solves the problem

Add the line to alsa-base.conf You may find that "options snd-hda-intel power_save" is already present in alsa-base, but it's set =10. Set it =0 instead.

Never Mind. I figured out how to use gedit to get it done and it seems to have worked. Thank you so much for the help Colin.
