Part Number: SRC4382EVM-PDK
Other Parts Discussed in Thread: SRC4382

Hello

I have an src4382/92EVM kit and want to use this for digital audio input so that i can record input using software tool like ffmpeg. when i connect the board using usb with my centos (linux) pc it shows audio card for input and out put and using arecord command i can find device in list. i want to take input from XLR input port (balanced digital audio) which is J5 and using command line i want to record audio but the thing is that when i run the command i can see that some thing is recording but when i playback that audio file i could not be able to here any sound. i am running following command - ffmpeg -f alsa -i plughw:1,0 -c:a mp2 1.wav                         

so can anyone help me to solve my problem.

Thanks

    Hello Jalaj,

    Unfortunately this is not a supported mode of the EVM.   While I agree that this would be a very interesting feature of the EVM,  The digital audio serial bus of the USB audio processor is not even connected.  This pins are left floating.  This USB audio processor is being used solely for I2C and SPI control of the SRC4382. 

    best regards,

    Hi Steve 

    first of all thanks for your concern regarding my post. will you please tell me the solution because i am new to this chip i have worked before on Xcore mc chip and that is very much easy solution but i heard that src4382 is much batter for digital (AES) audio processing. will you please tell me that how can i configure for i2c or spi to this chip.

    Jalaj, 

    You can use the TLV320AIC310x GUI to communicate with the SRC4382.  IF you are on Windows 10, you will need to download the updated drivers , but before you try to install them, you must disable the driver signature enforcement on windows... 

    we are working on an update to this GUI that will allow easier operation on Windows 10... but for now this is the workaround

    i have downloaded  TLV320AIC310x GUI but when i open it is popup a msg that connect USB also i think with SRC4382EVM kit something is wrong.what is pure path console 3 ? does it solve my problem. you know that my task is very simple i just want to record AES audio input in centos platform. it can be either XLR input or RC input. user guide is saying that i can take input from RX4 only it is J9 connector on DAIMB board. jumpers are set for I2C protocol.

    regards
