I'm using a Toshiba Satellite L775D, and while streaming video, from time to time the audio and video goes out of sync.
The only way to fix is to disable and re-enable the aforementioned display adapter.
My driver is up to date. (version 15.201.1151.0 )
I'm running Windows 10, although this issue was present before the update in Windows 7.
Does anyone have any thoughts? Do I need an older driver? Do I need to replace / upgrade the graphics processor? Is there some intermediate step that I'm missing?
Try disabling browser hardware acceleration to see if that has any effect. Additionally i would recommend ensuring you have the latest motherboard bios, windows updates and driver updates for your system.
