PROBLEM SOLVED
If you want to know how I got it to work with sound and improved mouse speed and save game problem I've actually installed it within DOSBox some people said you couldn't cause of the CD-ROM speed problem well I've proved something heres how
1. Create a file called STTNG in a drive (for me I placed it into my F: under another directory e.g. Dosgames)
2. Copy over all files on CD and extract sttngins.zip (do not extract sttng.zip) (Do not create a savegame folder)
3.Go into dosbox and mount the file is in as the C drive
4. mount your CD Rom drive as D:
5. type D: then type Install
6. Go through installation of AFU (if it says CD-ROM speed error decrease your speed above your DOSBox window By pressing CTRL + F11 you will notice the numbers where it starts with 3000 will decrease CTRL + F12 Increases it. ) Select 14mb version and Select C: at target drive installation (DOSBox will think drive you placed your STTNG folder is in the C drive)
7. Once installed exit installer (Don't tamper with sound and video yet)
8. type STTNG to start (If all is right, game should work without sound, notice mouse speed is much smoother)
9. during gameplay click out of DOSBox window and go to STTNG folder and enter the STTNG.ini file.
10 Here are the following changes to be made once on the file
Audio=SB8
Port=0x220
IRQ=0x7
DMA=0x1
Video=LO8
Sound=ON
Music=ON
Voices=ON
Movies=ON
Advice=0x0
VolMusic=0x7fff
VolSound=0x7fff
Dialogs=ON
Scale=ON
DPixel=OFF
Path=C:STTNG
CD=D:
UniVESA=OFF
Some may not need changing and may look like this
11. Save settings, go back onto game, play for a while then save. (Savegame folder should have been created after installation)
12. Quit back to dos then retype STTNG
Voila! Music should sound at the Spectrum Holobyte logo and intros and sound at various areas e.g. menus, voices, sfx
Thats the only way I've managed to get past that hideous sosDIGIInitDriver error
FORGOT TO MENTION
If you can't remember the mount formula for CD-ROM this is what I put (maybe different with other peoples Cd-Rom drive letters)
"Mount d d: -t cdrom"
Also when you mount to the file like this
"Mount c f:dosgames" (Don't use this this is an example of mine)
DO NOT ADD IN THE STTNG FOLDER YOU CREATED IN THE DIRECTORY YOU CREATED ONTO THIS MOUNT FORMULA BECAUSE IT CREATES A DUPLICATE FOLDER WHEN INSTALLING AND IT WON'T WORK IT WILL AUTOMATICALLY DETECT THE FOLDER YOU CREATED BEFORE INSTALLING AND ALSO BELIEVE ITS IN THE C DRIVE
