By default, audio is enabled (--no-audio must be explicitly passed to disable it). However, some devices may not support audio capture (typically devices below Android 11, or Android 11 when the shell application is not foreground on start). In that case, make the server notify the client to dynamically disable audio forwarding so that it does not wait indefinitely for an audio stream. Also disable audio on unknown codec or missing decoder on the client-side, for the same reasons.
