Hi. I’m using a fresh install of Volumio, last version (2.773)
I’ve tried to play .dts files. In the WebUI I can see the “dts” logo and “44.1 kHz 16 bit”, but I only hear noise. I can hear MP3, FLAC or WMV without problems.
The audio connection is via HDMI to A/V receptor, full dts compliant (Pioneer VSX-520).
In the FAQ (volumio.github.io/docs/FAQs/General.html) dts format is listed as valid with ffmpeg, which is not installed nor installable via apt-get install ffmpeg.
