Aiyima A5 Pro does not send sound to output from USB

Hello all :)

I have bought DAC Aiyima A5 Pro to use it along usb (windows) and RCA output (R1700BT), I have followed the steps to install the drivers and rebooted the pc but there is no output sound.

Windows shoes the bar with sound but actually there is no sound from the speakers, any ideas what could this be?  https://vidmate.onl/ 

I have also tried headphones output but it does not work.

Thank you in advance.

i got this...

If the headphone output on your DAC doesn't work, the problem is probably with the DAC itself (defective), selection of the wrong DAC input source, or with your connections to the DAC from your PC.
