haha funny 35% for me it is the same. wehen it's a kernel problem, shouldn't it then on all Pixel 4? does an upgrade or downgrade to another android could change the problem?

did you look if there is lineageOS or another custom ROM, who is based on a newer android?

it is also if I play a podcast trough the speakers with #AntennaPod. one of my often used apps btw. an excelent product and #floss.
