Laptop help...sound.

Are you using windows 10? if so, this happened to me after I received an update from Microsoft. I just googled "headphones not working after windows 10 update": and it appeared to be a common problem with plenty of info on how to get your sound back. It was something to do with the driver I think, I am sure i had to uninstall the driver and then restart my laptop so it would automatically reinstall the driver (but I would check google first)

Try going into control panel sounds and devices then Audio then advanced sound playback click on headphones.

Thanks for the reply,i will give that a try.

Normally it should be detected by laptop so it could be a driver in which case try updating driver
if not uninstall driver and reinstall with driver from laptop make website.
