To enable Audio, you simply need to click on the speaker icon beside the START/STOP button.
To stream video with audio in sync, it is necessary to have a buffer, which means that the picture will be static for a few seconds when connecting or enabling audio. This is done in order to ensure stability when streaming and to enable video/audio synchronization.
How Audio Streaming works
When the user is streaming Audio to an Airtame dongle, the sound is automatically muted on the user’s computer so that it only comes from the display. If the user tries to un-mute or adjust the volume on the PC, it will not have any effect on the received stream but may un-mute the PC resulting in audio clashing, where it sounds from two places at once at different times.
To adjust the volume, you must use the volume controls of the display that is receiving the stream.
