I think perhaps the OS is killing some process that makes the microphone work. I use this Pixelbook in a way that creates a lot of CPU and perhaps Memory pressure. OS is probably killing processes to free resources, but should not kill the microphone process! I have to restart the machine to get it working again.
Sometimes the microphone simply goes into a feedback loop rather than getting killed all the way. Perhaps there are more than one processes in that case.
This is not good. Can it be fixed? I cannot join meetings on time because of this issue.
Thanks!
