View Full Version : [SOLVED] Spontaneous speaker crackle on laptop in Karmic Koala
November 4th, 2009, 12:34 PM
I recently upgraded to Karmic Koala . The upgrade went flawlessly, but since then I have have noticed that the speakers give off an intermittent cracke every 10 -15 seconds , even if no audio file is being played. This happens even if if tap on the laptop Vol UP/down keys, but strangely does not occur everytime if i do it in quick succession. Seems as if some time is required for charge - like thing to build up ????. Pl. help
I'm running Ubuntu 9.10 32 bit on a Compaq AMD-Turion 64-bit laptop with NVIDIA graphics card.

I am having the same issue on my HP Pavilion dv 6000. I get one crackle then one second later i get two crackles then ten seconds later it starts over again.
I hear it on both the laptop speakers and external speakers at the same time. But when I disconnect the external speakers it stops after one more single crackle.
I thought at first it may be a system sound that was supposed to be a click or tic sound, but it is not effected by the volume setting or mute.

I suspect you're using a high definition sound card? check that with lspci in the terminal.
I found the solution to this problem in this thread http://ubuntuforums.org/showthread.php?t=1306963
It seems that the power saving feature with high definition sound card doesn't work so good.
Audio device: Intel Corporation 82801G (ICH7 Family) High Definition AudioController (rev 01)
Problem solved after commenting the line #options snd-hda-intel power_save=10 power_save_controller=N in the file /etc/modprobe.d/alsa-base.conf
