firstLocalAudioFramePublished property

Occurs when the first audio frame is published.

The SDK triggers this callback under one of the following circumstances:

• The local client enables the audio module and calls RtcEngine.joinChannel successfully.
• The local client calls RtcEngine.muteLocalAudioStream (true) and RtcEngine.muteLocalAudioStream (false) in sequence.
• The local client calls RtcEngine.disableAudio (true) and `enableAudio` in sequence.

The ElapsedCallback typedef includes the following parameters:

• int Elapsed: Time elapsed (ms) from the local user calling the RtcEngine.joinChannel until this callback is triggered.
