You might be affected by an audio issue Fairphone is currently working on to fix:

What is/was the "minor issue about the audio feature of the phone" "in less than 1% of the phones"?

Hi all, getting back to you on this topic. To make it clear: It is a timing issue in the firmware of the software that controls the Smart Audio Amp in the phone, and we are correcting it in a software release in Q1. I hope this provides some clarity for those of you experiencing audio issues with your Fairphone 3. Also, please make sure to contact Customer support anytime you are experiencing a problem. All the information is logged and provides valuable intel for improving the product.

Until then, the reboot seems the only known workaround right now.
