Why my DAC will not work with the Mus. Fid. V-Link

The OS or music player probably set the VLink to run at its highest spec which is usually 24/192 or 24/96.

The DAC spec says it only read 16 or 20 bits.

So try using the OS/player to set the output to 16/44

Thanks so much guys for your valuable input, it makes me understand a bit more about this issue, unfortunately I do not really know how to change the output to 16/44, I have a Mac computer.
Thanks again

Are you using any custom player like Audirvana or Amarra or Pure Music?

If you are using iTunes:

Look for Applications/Utilities/Audio MIDI Setup

It should look like the screenshot below, except you should have the VLink in the list. Click on the VLink icon

On the right, you can set the output bitrate and sample rate. Set them to 2ch 16-bit integer and format at 44100Hz

OMG, I GOT IT TO WORK!!!!!
Thanks so much, You're a genius.

Glad I could help.
