I downloaded the lastest Zynthian image and installed on my rpi4. I configured for onboard sound with Custom audio config. I also configured for HDMI video. The Zynthian gui kept restarting… with journalctl I noticed it was a jack server issue. I reconfigured for dummy audio device… Hi started. I updated the alsa config to use the onboard audio as primary … jack server failed again
I configured jack, alsa , and oulseaudio on other distros, no problem. Do you have a wiki entry regarding how to configure Zynthian on rpi4 onboard audio ?
I am using an maudio keystation 44 with it
Tested it on my i7nuc, Ubuntu 19.10, fluidsynth with the extreme keyboards sf2 soundfont and rosegargen. I would really like to try out Zynthian on my rpi4 4gb + flirc case 4amp power supply
