Volumio DSD file playback



A Raspberry Pi running Volumio is connected to the Directstream DAC via HDMI port so the DAC is used as an i2s DAC and it plays music fine. However when playing DSD files, Volumio indicates DSD 2.82 mhz/1 bit but the Directstream DAC indicates it’s playing PCM /192 khz/24 bit and not a DSD signal. Can someone tell me what’s going on?

Thank you.



Any chance anything in the chain is doing DSP, setting the volume or other things that might keep the system from being bit perfect?

In the How To pages here is a description of how to run the bit perfect test - http://www.psaudio.com/ps_how/how-to-run-a-bit-perfect-test-with-directstream/: it should help narrow things down a little.
