I can't "read" it because C is inherently unreadable ;), but I can usually
I have translated the libesd sound header(esd.h) if you want to try that
instead(esd is is Esound, the library used by GNOME for sound). they should
work with at least >=2.23, and probably earlier though I have not had a
chance to test. And if you look at the libsnd header, it looks like they did
almost a straight port using h2pas, aka minimal work, maybe just a little
cleanup to make it more pascal like. So while I do not know what the version
problem is, it would be easy to make an updated version, if I had copy of
both the new and old version for reference.
I would suggest however you try libesd first, as it is very easy to use, and
means you are not limited to using the sound system directly, and it works
on more platforms than Lazarus. Yes it means another dependency for your
program, but you can always
put your sound support into a dynamically linked dll, thus allowing you to
gracefully continue without sound, even if the dll fails to load.
