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.
