Thanks, I never did DOS sound programming but I got the idea. I also downloaded the book CD archive where are full pascal sources for sb lib and sample player. It's better to start debug something with sources. I just tried it run and they didn't work.

VOCDEMO.EXE - with autodetection it hangs, I can hear a pop at the start, when forced commandline options it ended with Pass no. 1, Runtime Error 005. It displayed that SB and mixer detected so I guess IRQ problem.

MOD386.EXE - misdetected IRQ to 10 instead of 7. When forced to 7 it ended with Runtime Error 103. It displayed that SB and mixer detected so I guess IRQ problem.

SFXPRO.EXE - started playing but no sound, doesn't support manual setup.

I tried some other demos from BONUS directory with 50% success rate. Even one demo that has sound setup and I properly set the resources didn't work - failed with SB detection.

UPDATE: I found some bugs in VOCPLAY library so it seems not be good sample to use...
