How do I get sound going via Bluetooth to pass through the Equalizer. I need equalization to cope with a hearing defect. Normal Headphones are fine, but not Bluetooth, all I get is a ‘muddy’ indistinct noise.
Please post more information about audio sinks (outputs):
pactl list sinks; pacmd dump | grep -Ev 'module|source'
Hope I do this right! oops , redonw, forgot to enable Earphones.

I suggest you install PulseAudio Volume Control to change the equalizer output sink to use the Bluetooth sink
pamac install pavucontrol-qt
Open PulseAudio Volume Control to show Playback tab
pavucontrol --tab=1
The equalizer should be visible as LADSPA Stream on Built-in Audio Analog Stereo
(if the equalizer controls are not visible change setting in bottom right corner to: Show: All Streams)
Click on the dropdown menu showing Built-in Audio Analog Stereo sink and select the Bluetooth sink Boltune BT-BH021
