630 Upgraded No sound when mirroring
Just bought a 630 Upgraded projector and got the screen mirroring working but only video, no sound except an occasional popping comes out of the speaker. HDMI works fine. USB 5 volt with lightning cable is the same problem. Video but no sound. Please advise on what is wrong or if there is any settings I need to set on either my phone or projector. Tried both an iPhone X and Android phone.
