Strange problem with a 2.1 speaker set and its mute function
Hi. I have an HP 15 laptop. The issue I'm having occured in windows 8.1 and now in windows 10 version 1511 build 10586.420 - same laptop.
Issue:
I have a new Harmon Kardon soundsticks 3 2.1 computer speaker set. This is connected into the headphone jack of laptop. The speakers work great, sound excellent.
They have a mute function where when you touch both capacitive buttons that control volume up and down at the same time on one of the speakers, the sound is muted.
However this mute function doesn't work when I have the laptop plugged into the wall outlet. When i unplug the laptop and the laptop goes into battery mode, it works perfect.
I tested the soundsticks with an ipod, a netbook and another exact same model laptop plugged in (same plug as problem laptop). The muting works flawlessly on all of them.
I can't figure out why this is happening. I've duped the settings as much as possible with the other same exact laptop and it still does not work.
I've tried uninstalling the realtek driver and reinstalling, doesn't help.
I've copied the power settings from the well working laptop, doesn't help.
Everything is updated. The soundsticks seem fine as they work correctly on everything (including a same model laptop with very sim config) but my laptop.
It does seem to be related to power somehow since the laptop unplugged has the soundsticks working right.
Is there a driver that deals with power I could uninstall and reinstall?
Laptop works perfectly otherwise.
Thanks.
