MacBook Air 2019 panic reboots with audio codec error

Can anyone give me advice on what to do with my MacBook Air 2019 that keeps panic rebooting. It's gotten so bad that sometimes the laptop would just not turn on even by holding down the power button. My laptop turned on again today so id love to be able to find some kind of solution. Below is the error message given to me:


panic(cpu 0 caller 0xfffffff02881ee30): "i2c1::_checkBusStatus Bus is still in a bad state; last read status 00010110 int shadow 00010100 xfer 00000000 fifo 00000000 for device audio-codec-output" @AppleS5L8940XI2C.cpp:571

Very often it is external devices that cause a panic of the Mac.

Shut down the Mac and disconnect everything but the power adapter.


Then restart the Mac in safe mode. Safe mode will often correct weird software behavior by forcing the OS to clear caches, do disk repair and other self-maintenance and housekeeping and temporarily disables third-party mods.

How to use safe mode on your Mac - Apple Support 


Use the Mac for a short period, say 30 minutes, then shut it down and restart it again normally.


If the panics continue, then your Mac may need to be serviced.
