Those messages refer to the LADSPA sink for pulseaudio. This is the
"Linux Audio DSP Architecture", a framework for chainable audio
effects plugins (similar to Steinberg VST in some ways).

Do you use any LADSPA plugins or effects on this system?

Pulse is attempting to load a graph with a LADSPA multiband equalizer
configuration defined:

sink_name=ladspa_output.mbeq_1197.mbeq
master=alsa_output.pci-0000_00_02.7.analog-surround-51 plugin=mbeq_1197
label=mbeq control=-11.6,-5.4,0,0,0,0,0,0,0,0,0,0,0,0,0"

The master sink it references doesn't appear to exist so it fails the
module load and gives up.

If you have configured any kind of EQ on the system then you might
want to try unconfiguring it.

Regards,
Bryn.
