I wanted to use the same converter on my new Samsung Smart TV to also connect a wireless headset ... And there, it was a disaster. For starters, if I play a movie with DTS 5.1 audio track (that natively supports TV), no sound comes out of my helmet (even with TV set to PCM output instead of DTS) ?! I was in against sound for movies with audio track DD (AC3). But the worst was the horrible noise, like loud noise when I was in a Smart App as Plex, DS Video, Netflix or Youtube, ... fortunately this noise disappeared as soon as a film or starting up a video ... But it was unbearable.
In short, I looked for a model that clearly stand DD and DTS 5.1, which properly detected no sound and finally that does not happen crunch during the short instant it detects if the source is DD or DTS (or other) ...
And bingo, Fiio Audio DAC that seemed the perfect candidate perfectly keeps its promises: D
PS .: Certain reports sometimes not having her with them to another brand converter for HD channels like TF1, ... No worries on that side with Fiio!
