I compiled a test multi-version of Volumio for VIM-1 (s905X) and VIM-2 (S912) and others TV box s9xxx. The system normally runs, allows you to connect a standard WebGUI. Sound working to USB sound cards. But still not working HDMI the sound output. I’m not an expert on sound, so I would be very grateful to those who will help to find the reason why the sound is not working to HDMI. The image can be downloaded from here. While the system works only with SD cards. Be sure to have activated the universal multi-boot.
Source code for building the image.
By the way, along the way I found an error in the profile for Odroid-C2 and assembled a working version with the latest source. If anyone is interested, I can give a link to a working image for Odroid-c2.
