That looks so damn good!

I threw together an Orange Pi One in a 1590BB enclosure a few months ago, and this post kind of inspired me to do so. I used an arduino nano for the I\O, a 2 dollar CM108 usb codec, and a 4 character LED display I had to write a driver for. With x-forwarding set up, I can just plug an ethernet cable in for full control.

I'm using armbian, and so far the audio works. Did you have to compile a RT kernel yourself? Thats the trick I'm currently stuck on. I can compile it but it wont boot.

It is also not nearly as pretty and well done as yours.

If you're curious, my github has the rough draft of it. An install script to compile from source and drag pd-extended's externals into the right place, set up audio permissions and x-forwarding, With a vanilla kernel (no preempt) it works well without dropouts. The next step is to design a PCM2906 soundcard with 2 in and 2 out audio and correct buffering.

Where did you get that enclosure? It looks like it has tons of room for expansion!
