I’ve just finished assembling my zynthian V4.4 (Got last week).
All seems working correctly, could connect trough ethernet and Wifi.
By connecting a keyboard to midi in, the led (Midi in) is blinking when the keyboard keys are pressed.
But I can’t get any sound at the 1/4" jack outputs (soundcard).
By enabling the RBPI headphone, I can hear the sound test from the headphone output but never from the soundcard output.
I don’t get any sound from the instruments (no sound at all, not from headphone out, not from the soundcard)
I’ve also done the software updates (triggered from the Web UI).
What could be wrong ?
Hello again,
I’ve tested again without changing anything. The audio test could be heard from the headphone output but nothing from the main output. On new information is that I could also hear the piano (headphone socket) with the midi test.
I’ve reburned with a fresh image (without doing any update), but now I have no sound at all
For the image I’ve downloaded the zynthianos-last-stable.zip file from the Wiki.
Dashboard copy:
I think I’ve found the problem:
A faulty Zynaptik module. Could this be possible ?
I explain: the really first time I booted the Zynthian, I had nothing (I’ve double checked all the connection before applying power).
At that time I thought it was the SD fault and checked this. I’ve also replugged all the connectors.
But here is the point, the second time I’ve connected only the first array of pins from the Zynaptik module. After these operation the PI booted, but with the problems I’ve described (no audio).
This evening I’ve seen that the connector was not correctly in place, put it in place and then again, not boot from the PI (as the really first time). By disconnecting the Zynaptik module the PI is booting. So it seems the Zynaptik module generates troubles…

Hi again, sorry !!
I think it’s getting clearer…
I’ve completely unplugged the zynaptik and (after software update) the audio and midi tests are working through the headphone output.
As I tried to trigger synth sounds using the midi din sockets, the led is still flickering (from the midi loop current I guess) but the data are not arriving at destination.
As a side effect also, the encoders are now also working correctly. Previously I could navigate but had some random jumps in the menu.
So now I can reasonably presume that the synaptik module is disworking ?
Thanks !
The MIDI functionality is implemented by the Zynaptik, so it’s not possible to receive/send any MIDI thru the MIDI DIN-5 sockets. Yes, you will see the light provoked by the current loop, but nothing more.
Now the more important. Is the main audio output/input working?
Please, try it again and if it’s not working yet, i will send you a replacement ASAP.
When you receive the replacement, please, send me the broken zynaptik by cheap “standard postal service”, so i can figure where the problem is.
I tried again to connect the Zynaptik board, but nothing to do, the board is not starting at all. No led is lightning, seems to create a short circuit.
Sure I can send you the board back. How do you want to proceed with the details ? Per private mail ? Or we continue here ?
Thanks !
Regards
