Part Number: TLV320DAC3120EVM-U
Other Parts Discussed in Thread: PUREPATHCONSOLE

Hello E2E Experts,

The TLV320DAC3120EVM-U is correctly recognized as an audio endpoint under Windows 11, see TLV320DAC3120EVM-U_USB_Log.txt. However, I am not getting any audio at the speaker/headphone output.

I cannot connect with the software slac366a: EVM Status: Communications Error

How do I get the TLV320DAC3120EVM-U to work?

    Hi,

    Unfortunately we have been having issues with the CodecControl software on Windows 11 (this is a known issue), it should work on Windows 10 and earlier but I know that is not a great solution for you. I am going to look into this more, see if we can figure out what the issue is that breaks it on Windows 11.

    In the meantime you can use CodecControl to generate I2C scripts for the device, it just won't run the scripts. You would need to use another MCU to drive that I2C communication. We do have some other old softwares like PPC2 or PPS that have been able to communicate over USB to the TAS1020B which is the USB controller on that board. I wonder if we can get it working with communication via these other softwares.

    Best,
    Mir

    For future reference:

    From the customer:
    "I solved the problem by running the init script, DAC3101_USB_Init.txt, from the slac366 software using the PUREPATHCONSOLE with the app Generic I2C Master. That worked immediately."
