Got Hifiberry DAC+ Pro working nicely with runeaudio+r e4 20200806.. haven't bothered updating to e5 yet. I get occasional mp3 playback audio glitches but i had that with my prior set up too so has nothing to do with DAC+ pro. overall i am very much enjoying the sound connected to my Rega amplifier.
Unfortunately not. In theory it should be possible to merge in rune audio the dsp part of hifyberry os. If I'm not mistaken they are both open source and hifyberry os seems well documented, but I don't have enough programming skills
btw: in the meantime I've switched both installations I have on R6. rern made a lot lf improovements and now it is very stable. Great work!
my hifi berry is working perfect on local and nas fioles, but after the last updates my blue tooth (phone/tablets) connection seems to corect connect an play but PI+berry won't produce any digital output (seen on DAC) , so no sound at all. anybody???
