I had some initial experimental builds some time back - Experimental setup: RockPi S + Vacuum Tube Hybrid Headphone Amplifier - but didn’t complete it and release them to the larger community.
So - here is a more recent build, with working I2S thanks to some help
I don’t have an 8 channel I2S DAC, but the board is quite capable if you want to try some multichannel DSP stuff.
2021-08-06, version 0.014
-64bit (kernel + user space)
arm64 - so plugins will need recompilation
WiFi might be finicky
I am having some issues getting the
armhf userspace working with the newer 5.10.yy kernels, so this is a
arm64 build that might be a bit rough around the edges with the 32 → 64bit transition.
