I have had this laptop (Windows 10 pro Lenovo IdeaPad L340 Gaming - core i7 9th generation) for about 2 years now. But lately I've been experiencing sound problems (no sound at all coming out of my speakers).
I tried reinstalling my drivers again which didn't work. Updating them didn't work either. Even putting in headphones (wired) doesn't work. However, when I have a Bluetooth device or a device connected from an HDMI, the sound comes out.
I've tried so many solutions yet none helped. When I open up my speakers properties it says "this device is working properly" but when I hit 'test tone' it gives an error can't play sound. Any help would be highly appreciated.
