[Bf-committers] No Sound in BGE on OSX, Can someone update dep's?

Sun May 3 21:40:08 CEST 2009

Hi,

I've attached a patch to use a WAV loading function that was already in
SND_OpenALDevice.cpp. This isn't ideal because this function probably
doesn't read some types of WAV files properly, but it's what I tried to
get working for Apricot after failing to get ALUT to work, and it means
there is no ALUT dependency at all.

Unfortunately even with that somehow sound did not work on the computer
I was testing at that time. Still it may be useful, if someone can
confirm it works or not, I don't have an Intel Mac to test. It works on
Linux and PPC Mac for me.

Getting ALUT to work or using a library like Alure I think is better in
the end, my patch is just a backup solution.

Btw, the patch that was linked to here using SDL to load the WAV file
will crash on loading packed sound files, because when reading from
memory it passes the memory pointer rather than a file name to SDL. From
looking at the SDL API, loading an WAV file from memory doesn't seem to
be supported unfortunately.

Brecht.
