Dear,Sir,

We occur a question about Audio Extract from the ADV7626.

Application :  the video/audio path is RXA --> TXA , and anabling Audio Extract from Receiver.

Testing environment: The HDMI output plug the TV, and the L/R out plug the Aktiv-Lautsprecher(SONY). The AV and the L/R out are narmal. On this condition, do the following test:

(1) Unplug the TV, the L/R out is interrupted, and then it output noise for about 1-3s, after that ,the L/R output back to the normal again.

  For this ,how can I do to avoid the noise? And If I can do that even unplug the TV, but the L/R out isn't interrupted?

(2) Pluging the cable connect to the L/R out continuously. Sometimes, it will lead to no video and no audio on the TV, and the L/R output noise all the time. At this time, such as Internal mute HDMI interrupts is present. I found that the messages.
