Music cues out of, or loose, sync (especially after save/reload)

ItsMeOnly commented 10 years ago

In many levels, the fading in/out musical motifs can, in some unclear circumstances (but mostly reproducible when doing save when cue is playing and then reloading), cue in at wrong parts of the melody:

Escape level / "An Accent Beyond" - the sync-sweep synthesizer cue,
old Aperture Science levels / "Forwarding the Cause of Science", "The Reunion" (this one is the hardest to reproduce) - the tremolo sync-sweep.

As a side note, in both Linux and Windows versions I could repetitively trigger these cues not fading out when landing on items, like rails, cubes.

Is this bug the same on Linux and Windows?

ItsMeOnly commented 10 years ago

Never encountered this bug under Windows, no.

So, in the last map before "The Escape" (turret trap) I tried to record the demo and, although I couldn't get the cues not to play in sync FOR the demo - the music starts OK, another issue popped out - the sync-sweep synthesizer lead sound is booming loud

Here's the demo: http://do.id.uw.edu.pl/~rambo/soundtest.dem

And here's a quicksave that is exhibiting out of sync cue: http://do.id.uw.edu.pl/~rambo/quick.sav

On a better note, I couldn't reproduce the bug in old Aperture Science levels anymore.

For the "sound doesn't cut off when landing on a rail", that's the error that the game is spitting to console: Error: Sound operator elapsed_time requires valid channel pointer, being called without one S
