Glad to see this is still being worked on!
I just checked the latest build of my old test game with the RC3 runtime. Runs great, but no sound unfortunately (Ubuntu 10.10):
Unable to initialize your audio hardware.
[Problem: Insufficient digital voices available]
Then again, using the older engine now also gives me no sound with no error messages...strange.
Yeah, first priority is to figure out how to get sound again. I've been looking at it from multiple angles but the only solution I can come up with is replace the default allegro audio system with a different one. (Like gstreamer audio. Hey, I'm already using that for the video, might as well extend it.)
The cause is PulseAudio, which takes over default ALSA, but doesn't do so properly, breaking a lot of stuff in the progress. And even if they get it right, pulseaudio delays the sound due to the way it works. Not a great choice there for the distros to having rushed in using it. Does anyone with a different OS get sound working?
I've also upped the allegro library version to 4.4, which seems to work just fine (it's fully backwards compatible with 4.2). Why? Since it's got OpenGL extensions, and I hope to use them for the linux build, allowing for a new option there and quicker rendering.
Of course, if Chris were to switch over to 4.4 with the windows version he could add OpenGL too... Though he probably has as little time to work on this as me.
