SPDIF no output when EVAL-AD2428WD1BZ as A2B slave

Category: Software
Software Version: sigmastsudio 4.7

Hello teams,

I have a question about EVAL-AD2428WD1BZ as A2B-slave. 

I have an EVAL-AD2428WD1BZ set as A2B-master (I'm sure A2B-master configration is OK/ A2B stream is TDM16)and another EVAL-AD2428WD1BZ configured as A2B-Slave. when A2B-Slavereceived audio from A2B-master, then bypass audio to Sound card by SPDIF. My A2B topology and A2B A2B-slave schematic as below.

            

unfortunately spdif no output.

so I tried to debug  about A2B-Slave configratiton as below,

step1: I add sine tone and connect to SpdifOut.  Sound Card received sine audio normally.  so Spdif output configration is OK. as below

step2: input audio from DTX0 bypass to DRX0(ADAU1452_SDATA_OUT0 pin),  I measure DRX0 pin and find audio data is OK. so I think input configration is OK. as below.

It is strange that input is OK and spdif is OK,  but input bypass to spdif is not OK.

this is my A2B-slave project as below, please help me check it.

Thank you for your time.

  • Hi  

    I think better to check if the downstream data from your Main node AD2428Wd1B to subnode AD2428Wd1BZ is properly reaching or not. 

    If not getting then please check the stream configuration of your project. There should be proper stream configuration between these two nodes in the downstream direction.

    Let me know if this work around didnt work.

    Thanks

  • Hi  

    thank you for your reply.

    I'm sure that the downstream data from your Main node AD2428Wd1B is properly reaching.

    I monitor  subnode AD2428Wd1BZ FS pin and  DTX0 pin as below,  so TDM16 is OK.

    currently I also monitor DRX0 pin and spdif out pin. both of them have data, but for spdif out data I need check it by AP the day after tomorrow.

    I will tell you as soon as there is a result. 

    thank you.
