TLV320DAC3120EVM-U: USB audio playback

Part Number: TLV320DAC3120EVM-U

Hi there,

I am currently testing the EVM mentioned above.

If i am to understand the user guide, I simply plug in the device via usb, attach headphones into the jack and execute the init program associated with the software.

However i find that the beep command works, and i am able to have a beep play both on a 4ohm speaker and through the headphones, but i cannot get the computer audio to play through the speaker.

Is there something i am missing?

Kind regards,


  • Hello Blair, 

    Make sure that your speaker output on your computer is set to the EVM and that the volume on your computer is turned up. If you cannot set the EVM as the speaker output, check to make sure that the EVM is showing up in the device manager properly and consider reinstalling the driver for it. 

    Let me know if you are still having issues after this. 

    Best Regards,
