can't completely mute sound on iphone 10XR
I need to have an iphone and iPad in the same room on a group Skype call. I do not want any sound going into or out of the iPhone. It is meant to be used as a video only supplemental camera for the call.
I have turned the iPhone volume all the way down and the Ringer switch is on Silent. When I speak, which is picked up by the iPad microphone, I hear a faint but audible echo of that sound coming out of the iPhone. Skype will not let me be in a call without access to the microphone so I can't deal with it that way.
Is there any way to cause NO sound at all to come out of the iPhone from a Skype call like this?
