ADV7842 HDMI Audio Muting

On page 256 of the ADV7842 HW Manual it says that, "The ADV7842 never mutes the audio data when it receives an audio sample packet with compressed audio data or HBR packets." But then on page 258 in Table 24 it lists several conditions that can cause an audio mute which don't appear to be dependent on the content of the audio packets. I would like to know if the audio outputs will mute if, for example, the incoming audio is HBR and the TMDS clock misses a pulse (MT_MSK_VCLK_CHNG condition)? If so, is this condition (or any of the others) subject to automatic un-muting if NOT_AUTO_UNMUTE is 0?
