Xubuntu sound popping every few seconds SOLVED

The popping is caused by power saving feature that can cause audible pops when your sound card sleeps and wakes up. So in my desktop I disabled this feature!

My sound card is an HDA-Intel

cat /proc/asound/cards

0 [PCH ]: HDA-Intel - HDA Intel PCH
          HDA Intel PCH at 0xf7f30000 irq 34

To disable power saving and persist this change after reboot:

>>> /etc/modprobe.d/alsa-base.conf <<< add
options snd-hda-intel power_save=0 power_save_controller=N

To test settings (in my case doesn’t work)

sudo sh -c "echo 0 >  /sys/module/snd_hda_intel/parameters/power_save"
sudo sh -c "echo N > /sys/module/snd_hda_intel/parameters/power_save_controller"
