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.
