[ubuntu] Karmic pulse audio 'popping' - nVidia MCP51 HDA - Ubuntu Forums

[ubuntu] Karmic pulse audio 'popping' - nVidia MCP51 HDA - Ubuntu Forums

The problem is due to your laptop's powersave settings. The pop your hearing is the speaker turning on as powersave has had it off while not playing any sounds. Try this
Code:

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

and change the line
Code:

options snd-hda-intel power_save=10 power_save_controller=N

to

Code:

options snd-hda-intel power_save=0 power_save_controller=N

If that doesn't work for you, you can try
Code:

sudo echo 0 > /sys/module/snd_hda_intel/parameters/power_save

as a temporary fix.
