HI,everyone

    I   am  useing  ADV7611  as  a  HDMI  receiver, now  the  video  signal is OK . But the audio is not.   When the source input is 1080P 60HZ,  the audio SCLK(bit  clock )  output  i  test is  96KHZ.   and  others  like 1080p 24hz,  720p 60hz 720P  50HZ and so on .the output SCLK is 48KHZ,  but  the  input source  the audio  is 44.1KHZ,  bit width is 8 bit.  and   there is no   signal output  on the AP pin .  what shall i do now ? I  used  the FPGA  to  conform  the IC.  Is there any  sugesstion? Thankyou very much !  And  the  REGEISTER  I USED IS  like  this .
