As you can see here - equalizer_presets_count is 4 - but the presets with names etc are not in the json output.
When I try the yaml output there is not even the equalizer_presets_count.

In json output of #450 I see the preset information is there.
I wonder why it is not working for my headset though. Any advice would be appreciated.
