Title: SCI: Raise PC Speaker volume

This fixes an issue where the SCI PC Speaker sound is very software compared to AGI and other engines.
The purpose of this pull request is to get feedback on the change and its effect on the existing code. I don't understand the code that well.

If this is indeed a desirable change then I will probably get rid of that #define altogether.
