You have an HD IDT audio chip installed.
Win 7 driver from HP. Select software and drivers HP Pavilion dv7-3174ca Entertainment Notebook PC - HP Customer Care (United States - English)
However, it could be this driver is already installed.
Does it make the pop sound when running off the external power supply, off the battery, or both.
With the unit plugged in it the AC adapter.. go to:
Control Panel/Power Options/ then select "Change Plan Settings" then select "Change Advanced Power Settings" scroll down to "Processor Power Management" and set Min/Max processor power to 100% (when running off external power) There should be a separate adjustment for running on battery power, leave it.
Reboot, see if that makes any difference.
It sounds like part of the power management system. Mac laptop users have been having fits over a similar issue... they go insane, so keep a cool head, it can be worked out.
