if (!SoundPause)

{

    IDataTypes->DoDTMethod(SoundObject,NULL,NULL,DTM_TRIGGER,NULL,STM_PAUSE,NULL);

    SoundPause=TRUE;

}

else

{

    IDataTypes->DoDTMethod(SoundObject,NULL,NULL,DTM_TRIGGER,NULL,STM_RESUME,NULL);

    SoundPause=FALSE;

}

This code works, but when resume the audio is partially garbled. Almost like it is playing from 2 spots, just slightly off, at the same time.

sound.datatype 53.27, X5000.

The problem could be in one of the sound datatypes (WAV, 8SVX, mpega etc). What type of sound are you playing?

I added your pause and resume code to a small playsound program. I added a small AmigaDOS Delay() before pausing the play and a small AmigaDOS Delay() before resuming sound play. I used a 5 second 8SVX vocal message and converted that message to RIFF-WAV for testing. I tested with the OS4FE 8SVX and WAV datatypes; then tested with the Enhancer WAV datatype. In all cases the Enhancer sound.datatype was used.

The OS4 8SVX and WAV datypes seemed to skip a fraction of a second of the sound when play was resumed but the sound played normally.

When I performed the same test with the Enhancer WAV datatype, the sound play resumed with the same garbling you described.

I can confirm the garbling problem with the Enhancer WAV datatype when the sound play is paused and then resumed.

I was playing/testing with MP3s and WAVs from Enhancer Pack. Same garbled with both types.

As I mentioned in your "Change datatype volume" topic, when I switched to the OS4 sound.datatype, I wasn't getting any pause at all. I might retest all this tomorrow to see if I tested correctly.

I don't believe the OS data type supports anything other than play and stop, so you might never get it working.

I'll investigate the jitter. I got this early on in development, but thought I'd resolved it - I've not had any issue for a while, but that doesn't mean I've not just been lucky.

To me the sound play after a pause sounds like it started from 2 different points but that be what you refer to as 'jitter'.
