Address Description
0x14[5] Causes audio mute if audio is compressed
0x14[4] Causes audio mute if audio mode changes between
PCM, DSD, DST, or HBR formats
0x14[1] Causes audio mute if parity bits in audio samples are
not correct
0x14[0] Causes audio mute if TMDS clock has irregular/missing
pulses
0x15[7] Causes audio mute if audio PLL unlocks
0x15[6] Causes audio mute if TMDS PLL unlocks
0x15[5] Causes audio mute if ACR packets are not received
within one VSync
0x15[3] Causes audio mute if flatline bit in audio packets is set
0x15[1] Causes audio mute if audio FIFO underflows
0x15[0] Causes audio mute if audio FIFO overflows
0x16[7] Causes audio mute if AVMute is set in the general
control packet
0x16[6] Causes audio mute if HDMI_MODE bit goes low
0x16[5] Causes audio mute if CTS changes by more than the
threshold set in
0x16[4] Causes audio mute if N changes
0x16[3] Causes audio mute if the channel mode changes from
stereo to multichannel, or vice versa
0x16[2] Causes audio mute if uncorrectable error is detected in
the audio packets by the ECC block
0x16[1] Causes audio mute if HDMI port is changed
0x16[0] Causes audio mute if TMDS clock is not detected
