What is a "Failed to load module "module-ladspa-sink"" error?
When I put in the terminal pulseaudio appears:
E: [pulseaudio] module-ladspa-sink.c: Master sink not found
E: [pulseaudio] module.c: Failed to load module "module-ladspa-sink" (argument: "sink_name=ladspa_output.mbeq_1197.mbeq master=alsa_output.pci-0000_00_1b.0.hdmi-stereo plugin=mbeq_1197 label=mbeq control=3.0,3.0,7.3,7.0,3.0,-1.0,-6.6,-6.3,-4.5,-4.0,1.1,1.2,5.8,7.9,8.8"): initialization failed.
E: [pulseaudio] main.c: Module load failed.
E: [pulseaudio] main.c: Failure to start the daemon.
How I can fix it?
I found this blog post with the same error and an explanation:
A few days ago I started having issues with the equalizer that is, no sound. I removed the equalizer as well as
ladspa-sdk. I promptly forgot about the whole thing until I rebooted and my machine began running super slow. Checking in syslog I found stuff like this:
pulseaudio[3662]: module-ladspa-sink.c: Failed to load LADSPA plugin: file not found pulseaudio[3662]: module.c: Failed to load module “module-ladspa-sink” (argument: “sink_name=ladspa_output.mbeq_1197.mbeq master=alsa_output.pci-0000_05_00.0.analog-stereo plugin=mbeq_1197 label=mbeq control=-0.2,-0.2,-0.2,-0.2,3.5,3.5,3.5,3.5,3.5,3.5,3.5,2.5,2.5,0.0,0.0″): initialization failed. pulseaudio[3662]: main.c: Module load failed. Failed to initialize daemon. pulseaudio[3660]: main.c: Daemon startup failed
Clearly the equalizer had left something behind when I removed it. Turned out the problem was in
~/.pulse/default.pa. The file had been modified in the install and not removed with it. The offending lines were at the end of the file. They looked like:
### Generated from: pulseaudio-equalizer load-module module-ladspa-sink sink_name=ladspa_output.mbeq_1197.mbeq master=alsa_output.pci-0000_05_00.0.analog-stereo plugin=mbeq_1197 label=mbeq #control=-0.2,-0.2,-0.2,-0.2,3.5,3.5,3.5,3.5,3.5,3.5,3.5,2.5,2.5,0.0,0.0 set-default-sink ladspa_output.mbeq_1197.mbeq set-sink-volume alsa_output.pci-0000_05_00.0.analog-stereo 65536 set-sink-mute alsa_output.pci-0000_05_00.0.analog-stereo 0 ### END: Equalized audio configuration
I commented out all lines shown by adding a # at the beginning of each line and saved the file. Problem solved.
So in short:
sudo nano ~/.pulse/default.pa
scroll down to the line shown in the quote and add a # in front of all the lines. Save and exit.
In newer versions, this file could also be at ~/.config/pulse/default.pa.
By a distro upgrade I had a corrupt pulseaudio configuration in my home folder in the ~/.config/pulse folder, receiving the same errors as you. I just moved the complete folder into a backup folder. Pulseaudio immediately created a new fresh config folder by its autospawn function. I had sound again! :)
