Correct me if im wrong but does DB Pro still activate the sound handling of direct X even if your program does NOT use sound or music at all?

I ask because an App i have written which is used in conjunction with othe window apps, seems to lock sound playback in any other application is open (seems to only occur with half duplex sound cards tho or those whose drivers dont allow mixing of audio playback from different apps).

So why does this happen? is there a way to tell the compiler to NOT include/activate direct x sound handling when you know your app will not be using it?

of course i am assuming this is causing the problem i have no idea so does anyone know for sure? Rob K? Rich? anyone?

Yes, I think it does.

This has been mentioned before, I think - if you use a function that also includes the sound commands, it gets included... I think Lee said he might be sorting this out in U7.

You could always use something BASS or FMOD - see if that causes a problem. If it does then its probably the card.

like i said, it works no problems on my machine my soundcard and driver are happy to share playback with multiple apps, so i dunno what ya trying to get me to see on my end. will bass and fmod stuff up playback in other apps on my machine?

Ya know what i would really like to know? If anyone knows what bytes to look for and what to change them to in a compiled exe to knock out the initialising of direct x sound in the app! now that would be handy dandy while i wait for the latest patch! so how about it anyone know what i should be looking for or what i should change it to? a NOP would work maybe depends on how things get started in the file tho...... im boggling now....... c'mon must be some hackers out there that have messed around with the compiled exe's! lol

Its to see if the soundcard can handle sound mixing properly.

You could try disabling the sound .DLL's.

In the DBPro folders, you should find a load of .dll files that get added to your executables on compiling - try renaming the sound ones so they aren't .dll, make them .dlx and see what happens.

The compiler will automatically exclude sound & music DLLs if you do not use any sound/music functions *unless* the sound/music DLLs are linked to one or more of the DLLs which you are using. These links aren't always obvious but they are there.

DLL inclusion on a per-function link rather than per-DLL link will probably be here a long way from now.

Try using the Twilight IDE; there is a menu where you can select which DLLs to include during compile so you can check off the ones you are not using (though I havent done this much myself). If might be a bit easier (and less dangerous) then renameing all the DLL you don't want to use.

Your project uses the memblocks DLL, and the memblocks dll has a MAKE MEMBLOCK FROM SOUND function. Even though you haven't used this function, because it is in that DLL, and it requires the sound DLL, the sound DLL is still loaded.
