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
Good news! You made me think that it’s been a while from the last time i tried, so i decided to “google” a little bit and … i found a trick for getting the RBPi PWM to work as a Delta-Sigma converter, witch should make a big difference with i’ve tested before. After a few tries and errors, i have a “not-so-bad” configuration and i decided to add it to the list.
You could update your zynthian image and choose from the list or try this custom audio configuration:
pi4 with a hifiberry is to compare night to day. I successfully ran 6 simultaneous layers of OB-Xd without any audio issues at all. foo-yc20 which was unplayable on a pi3 becomes the gold standard for transistor organ simulation. Others on this forum run pianoteq with higher settings. It’s revelatory.
I have my RPI4 in a FLIRC case, it’s a really good heatsink. I am definitely interested in buying a hifiberry Pro from you. I like the fact that I can boot up the pi and have a working keyboard to practice on. I’m using the Nice-Keys-Extreme sf2 , Upright Piano loaded. I just boot Zynthian on my RPI4 without the need of a monitor. On boot Zynthian loads up the defined synth layer… awesome.
It’s not much to look at. I just have the Audio going out to a Lepai HiFi Amp… out to my old Realistic Minmus 7 speakers. The RPI4 is a nonmodified FLIRC case.
The RPI4 runs cool in it
Ah! So you are using external USB or onboard sound? It will be interesting to see if you can fit an internal soundcard in the enclosure and connectors.
They haven’t yet produced the nice XLR based Pi4 implementation that are made proof against the tender gentle handling they receive in the audio world where, as I understand it, it isn’t considered usable till it’s been pounded by a pack of paranoid baboons on ketamine !!
