Jannis,
I am experimenting a bit with the guts of this.
If I have rewired my jack graph correctly, I have liquidsoap taking in the soundcard audio and sending it out as normal, at specified times, the same liquidsoap instance plays the files and sends it to the jack graph as alert.

I have normal audio going into the main inputs of the compressor, I have alert audio going into the sidechain inputs of the compressor. I have the compressor outputs and the alert audio going out to the soundcard.
It seems to be working as well as what I was doing before and seems much more simple...

More experimenting to come.
Thanks for the help everyone.

Thinking about it, it's possible:
Make the audio files go to the compressor's side chain input directly
and to a delay. That delay's output goes to the speakers.
This way, the audio from AES will fade out before the files' sound gets
to the speakers.
Making the audio files fade in some time after the audio files have
ended can be achieved by a reverb with long tail before the
sideband-input of the compressor.
This way, you could solve your requirements with one
sideband-compressor, one delay, one reverb, a command-line-player for
your audio files (mplayer, mpv, ...) and a cron-job that triggers it.
Best regards,
Jannis
