Here is how I fixed this issue on my laptop. I believe the 'Intel Smart Sound Technology drive is the culprit for this issue.
- Intel Smart Sound Technology for Bluetooth Audio
- Intel Smart Sound Technology for Digital Microphones
- Intel Smart Sound Technology for USB Audio
Open Devices and Printers, More Devices and Printer Settings, go to Sound, audio,controllers and uninstall all 3 of them. Restart.
Open the same option again, and then just click on Scan for Hardware changes.
These items will reinstall themselves after you do a 'Scan for hardware changes' so don't worry about uninstalling them. Restart your Windows If you get a prompt for that.
Check your sound setting, and you're done.
I tried literally everything on the internet, right from reddit to quora to other forums. This fixed my issue and is the only fix that worked on my Acer Laptop. let me know if it worked for you.
