G780 Sound issues

I have had my g780 for quite awhile with no problems until all of a sudden the sound only wants to come out of the right side headphone. Speakers work fine, but I only use my headphones, so this is a pain. I have uninstalled and reinstalled drivers several times, sometimes this will fix it and sometimes not. I can only get it to work properly now for maybe a week at a time now after constantly reinstalling drivers. Is this something Lenovo has been made aware of , possible fix coming?? Is this software related or hardware?? Causes??  Any help is greatly appreciated!

Re: G780 Sound issues

hi B26354,


Welcome to Lenovo Community Forums!


Try Removing all Manufacturer driver and install a Generic driver.


Open Device Manager and Look under Sound and Gaming controllers

You should have your audio listed there either Realtek, conexant.

Right click on it and choose Update driver

Select Browse my computer for driver software

Then Select Let me pick from a list of driver software

Now select the High Definition Audio

That's the generic driver See if after reboot using the headphone will show the same problem or not.


If The same problem, You might be having a HW concern.
