Cracking sound

Asked by Yeti on 2009-10-30

I upgraded to 9.10 beta from internet, and now when I installed full 9.10 release I have big problem! There is cracking sound from my speakers! It cracks randomly, cracks every 5-6 seconds! It cracks from my notebook speaker and from plugged in speakers. I didn't have this problem with 9.04 release... Please help me to solve this problem, I have HP530 notebook. It cracks even when I mute sound in Ubuntu, cracks when I disable internal audio hardware... Really don't know what to do...

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

I have no such file in that folder... This is all in it:


@Yeti: 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. That worked for me.

I think that 1st option solved my problem. There wasn't file named modprobe.conf but from terminal, with sudo it was created and I added 'options snd-hda-intel power_save=0' to file.
But just in case I have done and 2nd solution, found the line and changet it from 10 to 0!

Thank You very much Colin King and Alan Goldblatt!
