[Cin] ffmpeg 7.0 soon to be released

Complete failure with ffmpeg audio filters.
One premise, setting the audio driver to "pulse" the audio does not
work. Setting it to "alsa" works normally. I do not have Pulseaudio in
my system, but Pipewire takes pulse signals as if it were there. In
ffmpeg6 I do not have this problem.

None of the ffmpeg filters I have tried work.
The typical error is as follows:

PluginFAClient::activate: F_adynamicequalizer failed
  err: Option not found
PluginFAClient::process_buffer() F_adynamicequalizer
  err: Operation not permitted

The old CinGG with ffmpeg 6 works normally.

LV2 and native filters work fine, of course.
