[Openal] xfi issues

[Xavier Bouchoux]

hello,

so far I've been developping my code using the creative openal software 
implementation.
today I tried to give it a go on the X-fi fatality.

I'm observing this rather odd behaviour:

I create a single source, a single buffer, and link them together.
then I execute this code:

ALint State;
ALint CurBuffer;
alGetSourcei(Source, AL_BUFFER, &CurBuffer);	// --> 1
alGetSourcei(Source, AL_SOURCE_STATE, &State);
alGetSourcei(Source, AL_BUFFER, &CurBuffer);	// --> 1
alSourcePlay(Source);
... the sound finishes to play ... (actually I'm stepping in the debugger)
alGetSourcei(Source, AL_BUFFER, &CurBuffer);	// --> 1
alGetSourcei(Source, AL_SOURCE_STATE, &State);
alGetSourcei(Source, AL_BUFFER, &CurBuffer);	// --> 4096

oups. the buffer for the source has changed to some buffer I've never 
created.
Is this excepted? can the buffer be changed at any time?
If so, should I just ignore the buffer I didn't create, or should I 
delete it when I delete the source?


And I seem to have related issues with streamming sounds. I'll 
investigate a bit further.

Cheers,
xavier.
