Presario C500 - Crackling noise on startup

Asked by ascomar

When Ubuntu 9.10 boots up my Presario C500 produces some crackling noise (like the noise heard on a radio receiver when an electrical switch is operated).
The noise appears randomly (quite often) when using the audio subsystem (e.g. VLC player).
This laptop has been converted to Ubuntu from Vista where no audio problem was noticed.

I used to encounter the same problem sometimes on my new Karmic Installation. I don't know if it recurred later on because I guess I was kinda used to it but anyhow I did the following fix. I use Ubuntu almost full-time now (99.9% of it, rest Vista).
This fix is for Intel sound-cards, got it off 'WebUpd8' i think!

::Fixing The Popping Sound In Ubuntu Karmic::

If you use Ubuntu Karmic Koala beta and have a Intel sound card, you must be hearing a popping sound every now and then. This is a known bug and here is a temporarily solution for it.

Press Alt + F2 and type:

gksu gedit /etc/modprobe.d/alsa-base.conf

And comment (add a "#" in front of it) the last line called "options snd-hda-intel power_save=10". Basically, this is how the line should look after editing it:

#options snd-hda-intel power_save=10

Then save the file.
