Ticking sound when enabling aleep tracking

I recently switched from a Pixel 7 Pro to a Pixel 9 Pro (seems potentially relevant) and sleep tracking is unusable. As soon as I enable it the phone starts making this fast ticking sound irrespective of volume settings.

Hello @Scott_Curtis are you using Sonar? Sonar depends on the phone’s audio system and even it works well out of box on some model other devices may require some fine tuning. You may need to lower the signal strength settings in Sensor test screen, or try different frequencies…

Thanks, turning off sonar worked for now. I will play around with the settings at some later date.

Many thanks. Please keep me updated…
