[in]	audio_frame	Pointer to the encoded audio data.
[in]	tx	Pointer to an array of le_audio_tx_info elements.
[in]	num_tx	Number of elements in tx.

Return values

0	Success.
-EINVAL	Invalid arguments or invalid audio/frame/stream configuration.
-ECANCELED	Current call is intentionally flushed due to previous late timing.
