plugins via wine-bridges do not load with pipewire

[dschmidt]

Hey,

I apologize in advance if this bug report is invalid, but currently I'm completely lost where the correct place to file my issue would be or if it's just a misconfiguration on my end.

I'm trying to use Windows VST plugins via wine-bridges. Interestingly enough during the library scan, I get a popup that some software license management tool is not running (I never got this to work with jack either, but ...) that at least tells me that the wine bridge is in theory working. Also plugins are recognized and show up with metadata in the library.

When I try to load any Windows VST though, I get a popup "Failed to load plugin". On the console I don't see any useful output, just this:

$ carla

but those errors/warnings are already visible before I try to load plugins. When running any Windows VST in carla-single I get output like this:

Not sure if this is of any use. As I said I'm completely lost here and would appreciate any hint on what's going on, if this is just a misconfiguration, a bug or a missing feature in which project.

Thanks in advance!

You have to go in steps to see where the issue is.

1. can you load non bridged plugins?
2. on bridged plugins, can you load ones matching your architecture (try loading win64 plugins first, skip 32bit binaries)
3. can you load 32bit linux plugin binaries in carla (grab a 32bit vst linux binary from somewhere and drag&drop it into carla)

When you say:

'o != NULL' failed at ../pipewire-jack/src/pipewire-jack.c:4174 jack_port_get_buffer()
'o != NULL' failed at ../pipewire-jack/src/pipewire-jack.c:4174 jack_port_get_buffer()
'o != NULL' failed at ../pipewire-jack/src/pipewire-jack.c:4174 jack_port_get_buffer()
'o != NULL' failed at ../pipewire-jack/src/pipewire-jack.c:4174 jack_port_get_buffer()
Carla assertion failure: "audioIn1 != nullptr" in file CarlaEngineJack.cpp, line 2969

but those errors/warnings are already visible before I try to load plugins.

solving this first sounds critical.

[dschmidt]

Hey @falkTX,

thanks for coming back to me.

1. Yep, I can load native Linux ToneLib-GFX.vst3

2. Nope, both 64bit and 32bit bridged Windows plugins give me the "Failed to load file" popup. I now have an additional message in the error popup: "Invalid or unsupported plugin type". I'm pretty sure this line was not present at some point in my testing on friday, but I cannot prove that as I have no way to reproduce

3. Any hint for a 32bit linux plugin? Have none available and a quick google search didn't give me any obvious result

4. I cannot reproduce these errors anymore right now, but the plugin loading issues persist, so they seem to be unrelated to me.

The wine integration does seem to work tho, no? Otherwise I would not see the popup that some license management tool is not running, right?

[dschmidt]

Any way to progress here?

[falkTX]

well the typical thing would be to try first without pipewire, using real jack (even if in dummy mode).

and making sure pipewire is up to date, it keeps changing.

I dont use pipewire myself, so dont know about this in particular.

[DeeJayLSP]

I am having a similar problem, though I don't know if the reason is Pipewire.

Whenever I try to load a Windows VST a Failed to load plugin message appears and the log shows the following:

Carla assertion failure: "lib != nullptr" in file JackBridgeExport.cpp, line 35

Carla assertion failure: "bridge.func != nullptr" in file JackBridgeExport.cpp, line 60

A JACK or Wine library is missing, cannot continue

Using Kubuntu 21.10. I have all possible Carla packages installed. It used to work before. Is there something missing?

[MaciejMalczyk]

I built Carla from source from the latest commit and this problem gone. Of course with pipewire-jack installed.
