Mac book pro crashes due to audio codec issue

I have 2019 Mac book pro 16 inch with current Mac OS Catalina version of 10.15.7. Mac book crashes (nearly 10 times over 2 weeks) giving following issue of waiting for interrupt by the audio-codec driver. I have tried reinstalling Mac OS and removing most of the apps. The sound settings (both input and output) sometimes shows External Microphone even I haven't plug in one to microphone port (Image attached at the bottom). Please provide me any thoughts on this issue.

Seems like the problem is with Mac Os. I had enabled the power nap option on my energy saver settings which will lead to the panic in the kernel due to bug in OS from few versions back. Disabling the power nap (Untick the 4th checkbox in the power saver setting both under battery and power adapter tab) fixed the issue and it also reduced the heating of my Mac Book. But Apple should seriously consider fixing this which eat up lot of my time 😑.

Yes the issue with detecting the headphone maybe a hardware issue. But the kernel panic was a OS issue fortunately .

I don't think it is. While disabling Power Nap hides the issue, it is most likely a hardware issue. Lots of people want to bury their heads in the sand and hope it is not hardware, but if you take it to an Apple Store, they will likely swap out the logic board.
