In my understanding, dai->active can be 0/1/2.
But yes, we want to call mute if codec_dai is working

	/* Call Mute if Codec DAI is working */
	if (codec_dai->active)

	/* Call Mute if Codec DAI is used only for Playback or Capture */
	if (codec_dai->active == 1)

Thank you for your help !!
Best regards
