The file plays but the music cuts in and out about every second.
At first, I thought it was a hardware issue but I tried two different DACs, and then I also tried playing the same file through Roon using Ropieee with the same hardware it worked fine there. The DSF file is on a flash drive attached directly to the RPi.
So I think there is some issue with volumio and playing DSD files of this type.
Connected the rPi3 to the Topping E30II, for some reason it displays PCM, even though the same playback settings as used on the x86 (DSD Direct - 4MB).
Connected the rPi3 to the NAD D3045 (DSD Direct - 4MB). It doesn’t display DSD. So it seems the rPi3 mess around with the play back settings.
No, the Netherlands. So no easy shipping over. Do work for a US based company though.
Will run the same test with the 512 file tomorrow.
The NAD and Topping both supports DSD, so it’s strange that there is some conversion going on. Both other test systems provided the correct signal information.
These I2S DACs do not natively support DSD so Volumio has to convert them to PCM before sending over I2S. I have a feeling something is wrong with that process. Specifically referring to PecanPi and DAC+ DSP.
As we say in Dutch: Shoot me but leak (schiet mij maar lek)
Test 1: DSD512 - rPi3 - Topping E30II, DSD Direct - 4MB buffer - Mixer Type = None, No issues found,
Display shows 11.28 DSD Test 2: DSD256 - rPi3 - Topping E30II, DSD Direct - 4MB buffer - Mixer Type = None, No issues found, Display shows 22.57 DSD
(Test 2 was failing before) http://logs.volumio.org/volumio/CHdhlyl.html Test 5: DSD256 - rPi4 - Allo Digione, DSD Direct - 4MB buffer - Mixer Type = None, No issues found Test 6: DSD512 - rPi4 - Allo Digione, DSD Direct - 4MB buffer - Mixer Type = None, No issues found
