If you are using PlaySegmentEx to play your sound segments you can pass the DMUS_SEGF_NOINVALIDATE flag that will prevent it from killing any current segments.

soundperformance->PlaySegmentEx(
soundsegments[index], // Segment to play.
NULL, // Used for songs; not implemented.
NULL, // For transitions.
DMUS_SEGF_NOINVALIDATE, // Do not kill any current segments
0, // Start time; 0 is immediate.
NULL, // Pointer that receives segment state.
NULL, // Object to stop.
NULL // Audiopath, if not default.
);

hope this helps

Thanks for the reply.

I tried it but it didn''t help, the sound cut out when the second one started.

Should I be using two seperate audio paths? Or just the default one?

Thanks

Ooops forgot something. The sound segment that you do not want to stop should also have the DMUS_SEGF_SECONDARY flag set. I had some special things going on there I forgot about.

I think if you use this for all of your sounds you will be ok:


performance->PlaySegmentEx( segments[index], NULL, NULL, DMUS_SEGF_NOINVALIDATE | DMUS_SEGF_SECONDARY, 0, NULL, NULL, NULL );

They should play on the same audio path fine.

lol
I posted my sound encapsulation class source in this message but the HTML parser ate the file reading section and everything after it for lunch so I took it out... lol if you still have problems give me your email and I will send it to you.
