I'm able to reproduce this (all three of those games have demos on Steam, and
all three work fine in ALSA and OSS before the decouple patch), but I'm really
confused. I see the audio playing correctly (or it looks correct) from the
levels widgets in ossxmix. But, I don't hear anything through the speakers.
It's getting the audio data, but not playing it.

I tried dumping O_NONBLOCK to no effect. Calling SETTRIGGER to enable output
did nothing. As far as I can tell, the output device isn't opened twice while
writing, so it seems like that shouldn't be a problem.

So, why won't it play our data through the speakers?
