The all analog output from the CS4299 Pin will be Distortion with the 1k sine wave input(44.1k sample rate) from PC when i try to control the secondary codec with writing the TUSB3200AC's register bits ID1,ID0 of "CPTCTL"( CPTCTL = CPTCTL | 0x03 ) , For the ID1,ID0 , No problem with 00, but the analog output will be distortion at once when the ID1, ID0 changed to 01,10,11 the any one of the three value!!

however the input signal is 48khz sample rate , all will be ok!
it looks like the cs 4299's SRC not be started in condition with the 44.1khz input!

have you some code to controll two ac97 codec with Tusb3200 ?
it's urgent!
thanks:(
