Bad Usb Codecs

[Sabas]

Hello,

I used a usb to spdif converter, connected to my dac. The result was as follows:

The sound is different depending on which player is used. He utilizado Windows media,Vlc, Winamp.

Another thing I've experienced is that the volume of music is higher when the usb is connected.

It may be that windows media, vlc, make digital misinterpretation?
Also I get the impression that the sound is expanded.

I wonder if players who are faithful to the information?

if the codec that is installed when you connect the usb, is a good codec?

Regards
