I used to experience a popping noise when putting on some music, starting a video, etc. As this was just mildly annoying, it took some time before I bothered checking out how to fix it.
Turns out the problem was a common one amongst users with an Intel HDA audio based device. Good thing the fix (workaround) was an easy one! First open a terminal to confirm you have Intel HDA. Check what this returns:
If it returns something with Intel HDA, then your problem might as well be solved by this workaround. What we are gonna do is edit the configuration file for alsa. (Note: If you suddenly think “wait, I use PulseAudio, not alsa”, then do not worry, PulseAudio uses alsa). Open the following file as root with your favourite text editor.
If you are unsure how to do this, then press ALT+F2 and issue the following command:
gksudo gedit /etc/modprobe.d/alsa-base.conf
and comment out (this is done by putting a
# at the beginning of the line)
the line starting with
options snd-hda-intel power_save
Now save the file, go back to your terminal and type in
sudo alsa force-reload
to ensure the configuration file gets loaded in. (Alternatively, you can restart your computer)
