I have a HP Pavillion DV7 laptop with win 8 pro. The laptop has an unidentified problem with sound drivers or hardware that sometimes causes volume to constantly jiggle up and down. This is very annoying because of these consequences:
- Renders mute unusable - as the volume changes the sound unmutes automatically
- Causes an annoying win 8 "surface UI" notification to appear constantly in the upper left corner, which is distracting enough by itself, but more importantly
- Renders the whole "surface UI" unusable, because it loses focus whenever the sound changing notification appears
- When the jiggling happens, the laptop also loses the ability to redirect sound to earphones - sound comes out of the speakers even if earphones are connected.
To solve these issues I want to completely disable sound in the laptop (I've tried reinstalling drivers several times to no end). I have tried disabling all sound related drivers and devices in the Device Manager but Windows re-enables those automatically whenever I restart the laptop. The BIOS doesn't have any settings to disable sound hardware either.
Please don't suggest having the laptop sound serviced or fixed. It's not worth the expense. I just want to remove sound support so I can use it normally. It is very unusable as it is now.
