Not sure if this is the right place but I’m having the problem and I have no idea how to fix it and it’s driving me mad. So, sometimes when I’m watching a video downloaded on my computer using VLC my graphic card will crash and the sound will stop working if I change source it will work on thy source “headphones” but when I switch back to my default source “speakers” it won’t work and if I try play a video it will be really slow. I have to either restart my pc or restart my graphics card using win CTRL shift B and restarting explorer.exe. I’ve updated my graphic drivers to the latest ones not sure what else to do. How can I fix this any help is much appreciated.
