I’m upgrading to 10.5.7 to see if I can reproduce the problem, or to make a new build compiled against 10.5.7.
Hi, I’m with 1.6.2 Windows version and the audio is being a little buggy lately. With FMOD there is this error: “:audio(error): _channel->set3DAttributes(): The specified channel has been reused to play another sound.”
And when I change to OpenAL in Config.prc is almost 100% like it was before in 1.5.4. Almost because when I play a sfx, sometimes it stops in the middle of the sound.
Apart from that, congratulations for this new version, it’s pretty good. 
Hmm, could it be that you have too much sounds playing at the same time and that it starts reusing channels if it runs out of em?
Hum, maybe… I do use multiple sounds at the same time, it is usually around 3 or 4.
Well, now I’m back using OpenAL, almost good, it is a little unstable on the 1.6.2 version.
Is it now? How is it unstable - crashes? Have some sample code to show the problem?
My goal was actually to make OpenAL the default soon, so if it’s unstable, please let me know.
