Try it without using dfend - dfend could be mounting the game folder itself as drive, making the game not find its sound files.

i've allready did that, but no change. besides i have mounted my whole games partition so that shouldnt be a problem.

So you tried it without dfend ? Ascendancy works perfectly fine for me - i played it for days a few weeks ago. I can't think of anything it could be besides a bad installation or a bad mount.

Ok, i've just tried something different. I have the german original version of the game. Now i thought use a english version you can download from the net.
Made a new profile for that one in d-fend with the same settings and BOOM, i've got sound 🤣
Now thats really odd... the downloaded version contains files which the german version doesnt copy from the cd (ascend02.cob and logic.flc)
So i thought my original version might work if i copy those 2 files into the game folder... sadly it didnt work.
So, the english version probably got some sort of nocd crack.
And the mounting of the cd-rom seems to be not working like it should and thats the reason why i dont get sound cause the game doesnt find the soundfile (since it allways detects the emulated soundcards right).
