Ah, yeah sorry.  When you comment out the OpenAL_ErrorCheck() lines you
need to put "alGetError();" there instead to clear the old error
message.  Otherwise the previous error shows up on the next error check
which isn't what you want since they'll just pile up.

m_al_multichannel_id is just the OpenAL source id.  I'm already going to
change the name to make it a little more intuitive since I had to look
at that a couple extra times as well.  It should be ok as is though,
just make sure to clear the old errors like I mention above and try
again.  Hopefully you'll get better results now.

And just to note that I seem to be getting some strange error values too
on a few commands with OpenAL CVS.  The command looks to get executed
correctly but still throws out an error like it didn't.  I haven't
looked at this any further though.  You may be seeing a variation of the
same thing.

Oh the OpenGL extension list thing I mentioned is likely a bug in the
code.  I just noticed, and fixed, something similar in FS2_Open where it
reads past the string into random memory if the last character is also a
token (ie. " ").  When the extension string has a trailing space it
spits out garbage.  Easy fix though and it will be going in soon.  If
you still keep getting the garbage in the log then let me know since
that's not a good thing to leave messed up like that.
