Well, I have some problems with my G55VW speakers, what seems to be the problem is,
Whenever I plug a headphone the speakers are not muted and audio is been played on both the speakers and headphones at the same time.
Now I looked around about this problem and I managed to do manually mute the speakers and then unmute them after I unplug the headphones. Now here's a weird part. When I'm watching a movie with my headphones (while the speakers sounds is muted) the speakers just turn them self on by them self which is really confusing and the headphones audio still on. Anyone have any idea what is happening around here?.
Oh, I actually downloaded the update for the audio drivers but still the same problems happens.
Try to upgrade the driver to version 10400 if you still didn't do that, on my I unplug and plug again seems to solve the problem, they are working on a new driver that will fix all the audio problems on the G75 and G55... there is a Beta driver out some of the users have already tried and seems to solve... i'm still using the 10400 and i only have to unplug and plug again to get it working.
