TAS5805M: can't play sound on the platform(TAS5805 with ALC4050)

Part Number: TAS5805M
Other Parts Discussed in Thread: TAS5805, ,

Hi, TI's expert:

  there are some questions will need you support during we are tuning...

project function: USB2.0 convert audio with Amplifier , the solution is ALC4050 and TAS5805 .

  project status:  the Host can detect the USB2.0 audio device and can switch the USB2.0 audio on PC, but didn't hear any sound from the SPK.

                        we have checked the input I2S signal of  TAS5805, it seems has signal on it. but we don't know correct or n't.

                     the waveform as  below capture for you reference.

1. dose the TAS5805 must download any firmware or any configuration file to the ALC4050? 

  if yes, how to get them? could you share them to me?

2.our FW team have below question during they have tuning firmware.

1,  what are the I2C of amplifier(TAS5805) and the format?
2,  which values are need fill out that which register?
3,  does the ALC4050 only output the I2S signal of 48k or 16bit .

 4, it will through the I2C to configurate the register of amplifier to corresponding the format if the format of I2S has changed.

upon all ,kindly hope you support!

thanks!
