You can try it using the XM at http://www.freewebs.com/jeromeblouin/xa ... llenium.xm

As this seems to be an OpenAL bug, are there free tools to open XM/MOD files and save them in other mod formats?

Thanks!

The second XM I try craches as well. How stable OpenAL is for XM format?

UPDATE: Any mod/XM I try craches OpenAL. I use slick 237. Is there a dll I might be missing? Any other external dependency that create incompatibilities on my system?

Thanks

Looks like an issue with the streaming implementation. Could you try streaming an OGG and see if you get the same result?

OGG works just fine.

Is it possible that it's caused by my sound card?

It's a bit wierd if *streaming* oggs works but MOD/XM doesn't - if it were a sound card problem I'd think streaming was at fault generally.

Should I try with the streaming boolean false?

EDIT: Do you reproduce the bug?

I found the cause of the issue. My game can play any music format, no problem here. The issue is that I use more than 1 instance of Music class, not at the same time but when I call stop on the first instance, create the second instance and call call loop on it then OpenAL crashes. I Also call loop on the first instance at the beginning. So to me it's a bug either in OpenAL or on how Slick makes use of OpenAL.

Ho, new findings: if I set the streaming flag to true to both Music constructors then there's no crashes. :?

yep, but this shouldn't crash OpenAL right? So as soon as I don't ask streaming then the error occurs. That shouldn't happen.
