Sound Issue after Removing Pulseaudio Equalizer
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: module-ladspa-sink.c: Failed to load LADSPA plugin: file not found
pulseaudio: 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: main.c: Module load failed.
Failed to initialize daemon.
pulseaudio: 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

### END: Equalized audio configuration
I commented out the lines shown in bold by adding a # at the beginning of each line and saved the file. Problem solved
