/**
 * Connects the send transport for audio by producing audio data and updating the audio producer and producer transport objects.
 *
 * If the primary connection fails, it attempts to connect using the local transport via a separate function.
 *
 * @param {ConnectSendTransportAudioOptions} options - The options for connecting the send transport.
 * @param {ProducerOptions} options.audioParams - The audio parameters.
 * @param {ConnectSendTransportAudioParameters} options.parameters - The parameters required for connecting the transport.
 * @param {Producer | null} options.parameters.audioProducer - The audio producer object.
 * @param {Transport | null} options.parameters.producerTransport - The producer transport object.
 * @param {Producer | null} [options.parameters.localAudioProducer] - The local audio producer object.
 * @param {Transport | null} [options.parameters.localProducerTransport] - The local producer transport object.
 * @param {(producer: Producer | null) => void} options.parameters.updateAudioProducer - The function to update the audio producer object.
 * @param {(transport: Transport | null) => void} options.parameters.updateProducerTransport - The function to update the producer transport object.
 * @param {(localProducer: Producer | null) => void} [options.parameters.updateLocalAudioProducer] - The function to update the local audio producer object.
 * @param {(localTransport: Transport | null) => void} [options.parameters.updateLocalProducerTransport] - The function to update the local producer transport object.
 * @param {(level: number) => void} [options.parameters.updateAudioLevel] - The function to update the audio level.
 * @returns {Promise<void>} A promise that resolves when the connection is established.
 *
 * @example
 * const options = {
 *   audioParams: { codec: 'opus', maxBitrate: 128000 },
 *   parameters: {
 *     audioProducer: null,
 *     producerTransport: transport,
