I am trying to play a WAVE file continuously (i.e. until waveOutBeakLoop) on the AlphaStation 500/500 under DUNIX (MMERT 2.2). Under Windows 95 all that's required is: audioHdr->hdr.dwFlags = WHDR_BEGINLOOP | WHDR_ENDLOOP; audioHdr->hdr.dwLoops = 0x8FFFFFF; I'm using a single 20K mmeAllocBuffer. However, this seems to crash mmeserver. If I set dwflags = 0, my code plays the sound once just fine. Also, I can't find looping documented in the Programmer's Guide, so I'm going by Microsoft docs. Suggestions? Norm Saunders Fed. Govt. Region Engineering [Posted by WWW Notes gateway]

| 484.1 | DUNIX 4.0a,b? | NETRIX::"[email protected]" | Norm Saunders | Tue Feb 04 1997 11:58 | 15 |
I forgot to mention that this is happening with either DUNIX 4.0a or b. The install warns that it may not work with versions more recent than 4.0. One other thing... Although I supply a callback routine with waveOutWrite because I have to, the routine does nothing, and I am not calling mmeWaitForCallbacks or any other callback routines. I assume this is not the problem, because I can play the sound several times at widely spaced intervals. It's only when I try to loop the sound that I kill mmeserver. thanks for your help!

The reason the flag isn't documented on Unix is because it doesn't exist on Unix. The server crash is a bug however and should be reported through the PTT system. Tom | |||||

Your use of dwFlags and dwLoops is correct. They are described in the mmsystem.h file, as well as with the waveOutBreakLoop interface in the Programmer's Guide. Chip | |||||
