Ok, downloaded Mint 8 KDE Final and was going to fix popping sound with steps given and unable to bring up alsa-base.conf with the given command. Seing how gedit is for gnome is there another command for KDE? I listed steps that were given below. Any help with this is greatly appreciated.
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.
