Speaker not detected

[Blem383]

Have a new Dell laptop. Updated to new Zoom version and now I'm getting message that zoom is failing to detect speaker.  I am not that tech savy and tried unstalling and reinstall with same issue. During last meeting I had to connect audio to my phone but there was a lot of feedback. This is a weekly meeting that I have used zoom since 2020 before encountering this problem. 

I need Help!!! Please!!
