Indoor Camera speaker stopped working

Hello My Indoor cam speaker appears to have stopped working. I can hear audio and what I’m saying into my phone on the app but no sound comes out of the camera. The siren also doesn’t make any sound This has previously worked fine and my Ring Doorbell still works I have tried powering down the camera, holding the power button for 30 seconds to reset, deleting and reinstalling the app. Still no audio from the camera speaker This only seems to have been a problem since the app was updated recently I have checked on 2 iPhones and both are the same
