Subject: SCI: Fix broken speech after starting in text mode

Fixes bug #10924 where starting or restoring in text mode and then
changing to speech mode within a game results in muted speech.

This is a regression introduced between 1.9 and 2.0, probably as part
of the synchronization refactor that created GuestAdditions.
