Comment (by csnover):

 On Linux, once you set the buffer size to 1024 in ScummVM, the only
 difference between DOSBox and ScummVM should end up being the version of
 SDL in use. Could you try compiling ScummVM with SDL1.2 instead and see
 what happens? SDL2 in particular has some really questionable-looking
 pulseaudio code with some `PA_STREAM_ADJUST_LATENCY` define that messes
 with a bunch of stuff, which seems like it is the source of that half-size
 samples warning (because it does [https://github.com/spurious/SDL-
 mirror/blob/master/src/audio/pulseaudio/SDL_pulseaudio.c#L561 "this"] for
 [https://forums.libsdl.org/viewtopic.php?t=9248 "some reason"]).
