Does anyone know if PWM is currently broken on Buster? The hardware I am using has a piezo sounder driven off GPIO 30 of the CM3+. On Jessie and Stretch everything works fine but when using Buster the piezo is totally quiet. I used the same config.txt and dt-blob.bin on Stretch and Buster along with v68 of the GPIO daemon. I'm not sure what else could be wrong other than there's some issue with Buster.
