The following program was working fine yesterday, but today it has completely failed.

func (a *Assistant) UpdateAudio(track *webrtc.TrackRemote) {

	if track.Kind() != webrtc.RTPCodecTypeAudio {
		log.Println(color.Yellow.Sprintf("[assistant:UpdateAudio] Received non-audio track"))
		return
	}

	codec := track.Codec()
	log.Println(color.Gray.Sprintf("[assistant:UpdateAudio] Audio MIME: %s\n", codec.MimeType))

	if a.Channel.LocalAudio != nil && a.Status {

		log.Println(color.Gray.Sprintf("[assistant:UpdateAudio] Started audio"))

		for {
			rtp, _, err := track.ReadRTP()
			if err != nil {
				log.Println(color.Red.Sprintf("[assistant:UpdateAudio] Failed to read RTP: %v", err))
				return
			}

			err = a.Channel.LocalAudio.WriteRTP(rtp)
			if err != nil {
				log.Println(color.Red.Sprintf("[assistant:UpdateAudio] Failed to write sample: %v", err))
			}
		}
