Turn off the Cell Radio?
Ok, just finished a long test session using ZOOM in an attempt to setup a ChromeCast viewing session with ChromeCast transmitting both video and audio ;
android cellphone
OS 8.1.0
The goal was to be able to participate in a remote class using a cellphone and ChromeCast to enable the use a large screen
ChromeCast &quot;mirror screen&quot; works to get the phone video mirrored on the large screen, but the Zoom App only uses the &quot;Call Audio&quot; which is not seen by ChromeCast
Connecting to a Vizio soundbar and connecting via bluetooth does not project the Zoom audio
Using a Bluetooth headset does connect to the Zoom Audio (this is probably bluetooth device specific)
It is also possible to use the phone's audio jack to connect and amplify the Zoom audio output.
Using Airplane Mode did not address Zoom App's use of &quot;Call Audio&quot;
Removing the Sim Card did not address Zoom App's use of &quot;Call Audio&quot;
It has been suggested that using a mobile browser app for the zoom interface might also work... have not tested that yet.
Hope this info will be helpful to others with the same need.
