Sorry to dig up this old(er) thread, but I've also heard the problem in subLogic's "Airline Transport Pilot". Other than the digital sounds (used for air traffic controller messages), all of the other sound effects; including the one in question: the engine; are FM synth.

ATP suffers from the problem mentioned in this thread; after about 30 secs or so (maybe less), the engine sound drops out. As soon as you adjust the throttle faster or slower, the engine sound kicks back in for another 30 seconds or so.

Are you reporting that the problem exists in current source (unexpected), or just reporting another game/program that has the issue in 0.73 (expected)?

The version 0.73 release.

OK, please try it with a build of current source and report your results; or wait a (short) while and try it with 0.74. 😀

A-OK, I'll try it with 0.74 when it's released 😀 I originally misread, I didn't realize at first that the fixes were added.

You can easily download a newer Windows version of Dosbox here.
