Arlo pro 4 no sound when live

[SonicGT]

Recently I noticed I can’t turn on the sound when viewing live. 
the speaker has an x in it and clicking on it does nothing. When I watch videos it saved sound is there and I have sound on

i tried turning sound off then back on and still nothing 

I do have them connected to an Arlo hub.  
any suggestions?

Check the phone settings for the app to ensure mic and speaker are enabled.

My volume is up. The app settings themselves on my iPhone only allow me to turn off or on mic which is on. There is no option to turn off sound for the app

In the camera settings under Audio Settings is the mic enabled?

[SonicGT]

Yes mic is enabled and that works. Just unable to turn sound on. 

although I just checked now to potentially grab a screenshot and audio seems to be working today
