need help, about CS43122

[cubezone]

i build a DAC with CS8414 and CS43122 recently.

but ,the pin17(mutec~) of the CS43122 is always low, i have checked other pin , don't found problem. the pin25(CMOUT) is about 2.5v

this is the content i copy from the datasheet, "pin 17 ,Mute Control(OUPUT) -- the mute control pin goes low during power-up initialization ,reset,muting ,master clock to left/right frequency ratio is incorrect or power-down"

my question is , is the CS43122 damaged ? or some other method can be tested ??

thanks for advise.
