I have two problems with mij PI 3 and Volumio2.
I use a diy pcm1794 DAC with i2s connection, and it works fine on OpenElec with all sample rates up to 192Khz.
Now I want to use Volumio, but only mp3 and FLAC with 96Khz sample works well, there is now sound from WAV, FLAC 44.1Khz, 48,2Khz and 192Khz.(only short glitch).
I setup the Hifi-berry interface.
Wifi will not work on Volumio2, now I have try de latest, but older RuneAudio and here it works well (has also the same DAC problem).
I can’t find any bad configuration.
