Windows 10: Audio appears and disappears randomly

Hi all,

For no apparent reason audio from my laptop's internal speakers appears and disappears. As I was troubleshooting I noticed random fluctuation in the audio levels in Windows Stereo Mixer.

Take a look at this short video here demonstrating both the audio loss as well as the audio level spasms.

If I cast to an external device like a bluetooth soundbar, this does not happen. This suggests it's a laptop hardware issue but I would like to eliminate any other possibilities before buying parts/taking things. Plus, what's up with the sound mixer? That makes me think it's a software issue.

And as much as I know how I disabled/enabled audio devices, uninstalled drivers, installed different versions of drivers, etc etc.

Thanks in advance.

Most used apps list in start menu appears and disappears randomly upon restart.

When i restart my windows 10 pro the most used apps list in the start menu disappears and appears randomly. sometimes after a restart it disappears and when i lunch any app it gets added to the most used list and then when i restart again it appears empty
again.

And in other times after i restart it appears normally with a full list of my most used apps from before. how to fix this annoying issue?

 

audio randomly stops working

Hello all,

My computer is currently connected to my Vizio E420-A0 TV (HDMI). My audio randomly stops working and the display audio device disappears. When it works I can see it in device manager:








And when it stops working it disappears:





The driver seems to be up to date:





Disconnecting and reconnecting the cable doesn't help or turning the TV off and on, but rebooting fixes it. Any ideas?
