Hi,
I have the card running with regular raspberry pi OS, but would ideally use it with Volumio and the fabulous Fusion DSP plugin. The driver is not in the regular menu for i2S dacs. I have enabled dev mode, but it’s still not in there. I’d like to get the dac8x listed and try it out.
What do I need to do, besides request it through this post? 
(The dac8x offers 8 channels of dac outputs, it’s quiet enough to not make audible noise on my 102 dB efficient horn loudspeakers. Together with Fusion DSP based on tried and trusted Camilla DSP, and combined with Volumio as a very conventient streaming device, I think it’s pretty much all I want to combine my loudspeaker building hobby with my music listening hobby. Linux command line is a fun challenge now and then, but it’s not my main hobby and it’s not my strength.)
Thanks
Ivo
