Hello everyone,
My past few days have been really frustration with the issues I'm facing with my MacBook Air 2019 128 GB Variant. I recently installed Big Sur and ever since that time my MacBook loses audio all of a sudden while working, the only way around to get rid of it is shutting down the lid and pulling it back, that fixes it for a few moments but that is it. The laptop just keeps losing the audio.
I have also tried:
None of that helped, when I installed Catalina back to this thing it did help for a split second, it was a bit better but again it just won't stop losing audio. The other way I fix this sometimes is by going to the Terminal and killing the CoreAudio service which restarts it and then the audio is back for a few seconds. There are literally no other issues on the Laptop, this is it and it all started after installing Big Sur and although I tried to reverse it, it did not help. I cannot visit any Apple Service Center as of right now but I would really appreciate it if you can help.
Also, I tried to see logs for the CoreAudio service on Terminal and got this:

I have also tried:
- Resetting the PMC
- Resetting the NVRAM
- Reinstalling macOS
- Reinstalling factory macOS
- Restarting the MacBook
- Uninstalling almost all the Apps that I've installed
- Cleaning and removing any dust in the Headphone jack (I never use it)
- Disabling Bluetooth (I normally use AirPods Pro)
