I have some files disguised as stereo audio files but with DTS encoded sound within, I can listen to them perfectly on my PC and laptop with a Windows system, using foobar, WASAPI and HDMI output. The amplifier lights up the DTS symbol and I got nice 5.1 music coming out of the speakers.
When I try the same with RuneAudio (v. 0.3-beta) on my RPI3 it just outputs noise, which is what is expected without bit perfect output. It is giving me the same experience I get in Windows when I don't get bit perfect sound. For instance, in Windows if instead of WASAPI, I use a DirectX output I also get noise, changing the volume down from 100% will also output noise: it really has to be bit-perfect output. In fact, the way I test bit perfect output in Windows is precisely by playing a DTS file.
Now, these files, as far as I understand, are just normal WAV files, 16 bit encoded, nothing strange about them except for the content. When they are delivered to the amplifier it recognizes the stream as DTS. I don’t understand why I can’t play these files using RuneAudio. I tried several things, I already had volume, replay gain and normalization disabled, but I also changed the DSD, gapless, FFmpeg decoder settings and tried different sound signatures but it didn't make any difference.
Regarding the files:
In the UI, playing tab, it says: Stereo, 16 bit, 44.1 kHz, 1266 kbps.
Through ssh, using the Linux file command I get:
FLAC audio bitstream data, 16 bit, stereo, 44.1 kHz

Can someone help me both to solve and to elucidate what’s happening?
Thanks in advance : )
Edit - just to make it clear, I'm connecting the RPI3 to the DTS amplifier in exactly the same way (HDMI output).
Edit2 - a DTS file to test this condition can be found here (1.3MB)
