so, I’m not so far away to get zynthian to work on my nanoPi m4v2 (see here also: Questions about zynthian OS automated build system - #9 by le51), but I’m stuck with jack server.
I first started from a desktop installation of armbian, with qjackctl. Everything work well with:
then I run step by step all the scripts from zynthian-sys/scripts for installing zynthian software (except jack2, linuxsampler that have failed).
Here is my /etc/systemd/system/jack2.service :
[Unit]
Description=JACK2 Audio Server
#After=sound.target
Problems: I can’t add new layer, but the touch is OK + I’ve got no midi in signals from the step sequencer (wich is usb connected) + a bunch of errors from UI + many Xruns …
I do not really understand what you mean. But a quick search show me that this is a recurrent problem when running jack without Xorg.
For now, in my jack2.service, I use:
dbus-run-session /usr/bin/jackd …
as found here on linux-audio forum and it seems to approximately “work”:
After boot, I got ERROR screen, no jackd running job
systemctl stop zynthian
systemctl stop jack2
systemctl start jack2 => it starts …
systemctl start zynthian => UI starts, but I can’t add a new layer, and a lot of Xruns
