View Full Version : [ubuntu] Strange noise from internal speakers on laptop

January 23rd, 2010, 06:32 PM
Before I begin please excuse me if my English is not very good!

So my internal speakers on the laptop (MSI VR610X-022) are making some strange cracking sound from time to time. I don't think it's a hardware issue because they work fine with Windows. Currently I'm using Ubuntu 9.10, but I found that the problem also exists on 9.04. Please help 'cuz that's really annoying ...

00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
I'm pretty sure that my audio device is actually from Realtek (I use Realtek drivers on Windows), but this is what lspci said so ...

EDIT: There's noise even if i turn the sound off...

I have got the same problem.
Even when I turn the sound off completely (volume 0%), the cracking sounds remain.

They happen when I open new windows (like a browser or Nautilus) or sometimes even when I move the mouse. This happens since 9.10. I have got a HP Pavilion dv6000

ok, I have found a possible solution here (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/417302):

We can close this thread.
It is not a defect in alsa or anything else.
The main problem is the power-saving option in the intel hda module.
The sufficient fix is to modify the line in /etc/modprobe.d/alsa-base.conf containing something like
options snd-hda-intel power_save=X
Just remove the whole power_save=X option and that's it.
Restart is required than.

This doesn't work for 10.04 lucid. Does anyone have an idea on how to fix it?

Can you post the output of these terminal commands for me please:

uname -a
aplay -l
cat /proc/asound/version
head -n 1 /proc/asound/card*/codec#*
Also helpful is the make/model of your PC/Laptop.
Please post text output using code tags (the # in toolbar)
