ladspa dsp module will not load after updating to pulseaudio 12.0_1 on voidlinux,

[exaiyo]

I updated my system and noticed that dsp was no longer working, so I checked pacmd list-modules and it is no longer there. My config hasn't changed, the sink is still the same name, but I cannot get the module to load.
The following command cannot successfully load the module but I see no error message.
pacmd load-module module-ladspa-sink sink_name=dsp sink_master=alsa_output.pci-0000_06_01.0.iec958-stereo plugin=ladspa_dsp label=ladspa_dsp

Reinstalling the newest version of your dsp plugin didn't help either.

Any idea what might be wrong? The one time I choose to update voidlinux without making a backup first, this happens...

Thanks, your plugin is the best!

Hard to say without an error message... Did you do a full rebuild (make distclean && make && make install)? You could try running pulseaudio in verbose mode:

$ pulseaudio -k
$ pulseaudio -vv

[exaiyo]

I had not run the command "make distclean" I was unaware of that one. Now I have run make distclean && make && make and run pulseaudio in verbose mode. It says "no such file or directory", but I do see ladspa_dsp.so in /usr/lib/ladspa with 755 permissions so I'm not sure why. Here is the relevant section.

Now I have run make distclean && make && make

Make sure you run make install (as root), not just make for that last command (not sure if this was a typo or not).

[bmc0]

If it still doesn't work after running make install, post the output of this command: ldd /usr/lib/ladspa/ladspa_dsp.so.

[exaiyo]

Yes that was a typo, sorry. Here is the result of ldd:

# ldd /usr/lib/ladspa/ladspa_dsp.so
linux-vdso.so.1 (0x00007ffdb85f6000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00007f576937f000)

Hmm... Maybe pulse just isn't looking in the right place for some reason (though it should be, according to the documentation...). Try running pulseaudio like this:

$ LADSPA_PATH="/usr/lib/ladspa" pulseaudio -vv

[exaiyo]

Yes that appears to have fixed the issue. Once again you are the best. Is there any way to make the change stick? In my .xinitrc file I had to add start-pulseaudio-x11 & in order to get sound working alongside firejail. I'm not sure if that is relevant.

[bmc0]

Setting that environment variable shouldn't be required, so someone must've broken something. It seems to work on Arch, so maybe it's a problem with Void's package.

Anyway, you could add export LADSPA_PATH="/usr/lib/ladspa" somewhere (.xinitrc, .bash_profile, .profile, /etc/profile.d/...), then log out and log back in.

Another option is to go against the recommendations in the PulseAudio documentation and give the full plugin path in your pulseaudio configuration:

pacmd load-module module-ladspa-sink sink_name=dsp sink_master=alsa_output.pci-0000_06_01.0.iec958-stereo plugin=/usr/lib/ladspa/ladspa_dsp.so label=ladspa_dsp

[bmc0]

You're welcome. Thanks for the kind words.

Hi

For me full path can not help.
Compile with ladspa 1.15 and pulseaudio 9 on Slackware distro.
