Enable pc speaker support, if the game supports only that

 Activate "Enable pc speaker support" if you want your game to have a speaker support. You know, the usuall bip-bop type sound you will hear. If the game runs only with the speaker support, you will not hear anything in game, if you not activate "Enable pc speaker support".

 Or, with making your own .cfg file for the respective game, write true and not false in "pcspeaker=false".

White screen appears for a few seconds when launching DosBox turbo. No problem for DosBox turbo manager.
The developer has told us that this appears, but it is not detrimental to DosBox turbo. I have not found any problem.
