lsp-plugins-1.2.33-1 doesn't work [SOLVED]

Maybe I'm doing something woefully wrong, but after I upgraded to lsp-plugins-1.2.33-1, the LSP standalone plugins stopped working. In version 1.2.33, the output of

lsp-plugins-compressor-stereo --list-backends

is

List of available audio backends:
  dummy      - Dummy Audio Backend (builtin), priority: 0

and I don't see the plugins in qwggraph, presumably because they're using dummy output. I downgraded to lsp-plugins-1.2.26, which has no

--list-backends

option, and everything works again.

Now I'm not sure what to do. It might be an upstream bug, but the Arch package isn't working (at least for me). Should I file a bug upstream, or with Arch, or am I doing something wrong?

I'm pretty new to LSP plugins, but if downgrading to 1.2.26 fixes the issue and 1.2.33 only shows the dummy backend, it does sound like something may have changed in the newer release. I'd probably check with the upstream project first to see if others are seeing the same behavior. If it's specific to the Arch package, they can usually point you in the right direction.

Any error messages in e.g. the pipewire logs on why it can't load the plugin?

journalctl -b --user-unit=pipewire

for the current boot's pipewire logs

Re: lsp-plugins-1.2.33-1 doesn't work [SOLVED]

journalctl -b --user-unit=pipewire

only showed "Started PipeWire Multimedia Service." Nothing else I saw in journalctl looked relevant.

I posted something on the LSP Plugins github here.

It turns out that the audio driver code was moved to two new packages: liblsp-audio-jack-lib and liblsp-audio-pipewire-lib. I installed the JACK package and everything works again.
