To check, I applied the Debian patch audio-pause against espeakup-0.80
in Slint, rebuilt and installed a package repkacing the previously
installed one.

I observed in Slint the same behavior as in Debian: no speech from
espeak when going back to console mode from graphical mode.

All was correct again installing back the previous package, without the patch.

Looks like a confirmation, I think.

I couldn't check that in Slint because we don't use systemd.
