Hello.
I’m trying to set up sending audio through network. For now I have successefully created a zita-j2n service and it’s connecting to PC. but mod-host is refusing to work with. Seems it adds output ports but with incorrect names.

Mar 13 14:31:26 pistomp jackdrc[367]: Unknown destination port in attempted (dis)connection src_name [effect_6:out_l] dst_name [system:in_1]
Mar 13 14:31:26 pistomp jackdrc[367]: Unknown source port in attempted (dis)connection src_name [system:in_1] dst_name [effect_6:out_l]

And jack connections are:

there is already a jack-over-network connection.

enter the settings and go to the Advanced section: MOD Web GUI User Guide - MOD Wiki

It’s not working for me. Neither USB gadget not working. I tried lot of things and zita-njbridge gave me closest result. It’s running and showing output ports in GUI, but can’t connect due to ports misnaming.
Enabling netmanager does nothing as jack-netmanager.service does not exists. I cant find it somewhere on github.
Enabling USB gadget gives me nothing but dead jack and flood of jack errors in syslog and 100% cpu usage of mod-host.

I’ve tried zita-njbridge with desktop PC and old laptop and it worked just fine with little latency. Now i want to get it working on raspberry pi with MOD software.

It seems to me more some pistomp configuration issue rather than a MOD one. Also, after shortly looking at Zita-njbridge it seems that it does some resampling… I would really suggest to go the jack-over-network way

Oh sorry. I thought you mentioned using with our devices.

With the RPi I do not know :slight_smile:
