I think you may have nailed it on the head with the problem being related to Open AL. I hadn't noticed before, but every time I have gotten an error since then, I see mention of Open AL (and as mentioned before, this can occur even when the Task Manager indicates I have 2 GB or more of available RAM). Just for the sake of understanding things better, what do you mean by Open AL being "native"? Does that imply it is part of the Open Rails install, or something else? Is there any way to make Open Rails use a different component to play sound, or would that be an extremely complex task involving re-writing the whole sound code for Open Rails? I have tried reducing the Sound Detail level, and that does not solve the issue. I think it may have to do with OR not being able to easily handle these long freight trains with dozens or even hundreds of pieces of rolling stock fighting to output their own audio.
For the record, I very frequently can hear weird effects with the sounds, such as my engines sounding like jet airliners taking off (I presume from having the same sound playing simultaneously from multiple locomotives) and I experience a great deal of scratchy static background, which would seem to me as evidence of the game being overloaded with too many sounds.
It is rather disheartening, as I usually cannot run an activity for more than about 30 minutes without a crash, and that is while staying in the cab. Frequent camera movements around the train usually kills the simulation within 5 or 10 minutes tops. :( I do hope that some manner of priority can be given to tracking down what is causing this.
EDIT: I have been able to duplicate an error over and over at the exact same location on the Horseshoe Curve route. I get the error regardless of Sound Detail level, and regardless of whether MSTS Bin Compatible sound is on or off. Attached is a log file for that error.
