How to communicate with teammates when using the Android screencasting master to open the microphone

Since the voice transmission occupies the mobile phone microphone, if the voice transmission is selected, in principle, it is impossible to communicate with the teammates.

Requires an audio cable, an external microphone, and a headset/charging splitter as shown in the picture below.

Sound transmission line:

External Microphone:

Type-C to 3.5mm headphone jack connector:

Insert the male plug of the sound transmission cable into the blue Line in port of the external sound card.

Insert a female plug at the other end of the sound transmission line into the microphone interface of the headset splitter.

Then plug the external teammate communication microphone into the other female socket of the sound transmission line.

Finally, insert the USB interface of the external sound card into the computer, and then you can transmit the sound and communicate with teammates in the game when the game is broadcast live.
