I recently posted about the Vero being used as a transport for a USB DAC, and I noticed in a stereo system that with everything enabled for passthrough, I could still adjust volume using the Kodi remote. That suggests the Vero is processing the PCM when it’s not desired/needed as the passthrough options don’t seem to affect PCM sources.
I just repeated the test on an mkv file with a 5.1 PCM soundtrack into my 7.1 AVR (there are quite a few titles with PCM audio), and although the channel layout is preserved, it’s clear that volume processing is still active, whereas for a DTS-HD/Dolby passthrough, volume processing is not active.
Would it be possible to have an option for fully disabling volume management where it’s desirable to ensure that volume is only being managed in one place, as we can’t do this currently with PCM sources?
