First of all, you have been doing a great job with Volumio project and I’ve been enjoying it a lot on my HiFi system.
I currently have two setups:
Beaglebone Black with AK4490EQ USB DAC on Volumio 1.5
Odroid C2 through HDMI (max. 32bit/96kHz) on Volumio 2
Since there is not Volumio 2 support on the BBB, I was thinking to use an Raspberry Pi 3 with my AK4490 dac, and leave the Beaglebone for other DIY projects. The Rpi 3 is $35 on amazon and I know its a popular board for DIY use.
Before buying it, I would like to know how the Raspberry Pi 3 worked for you with Volumio 2? Or should I keep using the Odroid C2? Note that I have been experiencing some minor instability issues with the Odroid, and it does not play 24/192 through HDMI.
IMHO yes, mainly for the fact that PI3 is the most used platform out there, and we focus our resources more on it.
However, I don’t think you’ll get bitrates higher on HDMI, just on USB and i2s.
As for speed, C2 is a beast, way more fast than the PI3, but as you said, we’re encountering some stability issues (due to a mix of kernel related issues that are quite hard to solve)
Stability issues, which stopped us from taking the latest kernel have been resolved.
This was due to a major update on the Hardkernel repo, which we did not anticipate enough.
(overlayfs version change, audio driver changes, new u-boot version).
Patrick, we did not maintain any official hardware specific changelog sofar, not for RPi nor Odroid.
But it might be a good thing to do this. There is a very basic list on github covering the socalled platform files, these include kernel files and platform-specific files we need for building images.
Yes, the current C2 version is based on the latest kernel, there were more changes than we expected ( I did not update since April), some of them making our image incompatible. That has all been fixed.
