Hello @arkhhh, @Baggypants and @mheidt,
sorry to hijack this thread, but I just want to give some hints because I started with a new image as well but built it myself…
At first when I built my zynthian Kit V2 I looked at the photos for the orientation of the H11L1.
I was glad because I soldered them on IC sockets.
If your MIDI In and MIDI THRU lit if you start your zynthian you need to solder them turned around. This must be updated in the wiki and I am sorry for everyone who has soldered with the photos in mind.
Now for the software part: It might not solve your problems with sound on your zynthian first but it will help you update.
After first boot when you log in via ssh you find the commands from the first install script:
I think at this time date and time are not set.
So I did a
htpdate -t -s www.isc.org
as found here
Then I started zynthian software update on the zynthian itself and it updated.
Don’t let yourself get fooled because your zynthian might not do something for a long time while downloading.
Rebooting or powering off helps in my opinion, too.
If you see the updating process coloured when started from your zynthian via Admin menu you are on a good way through the process.
I hope that helps
Greetings and God bless, Marius
