ok, just verified, STEAM and Origin versions are different installs, bearing different files (STEAM seems to be multi-language), maybe that's why it doesn't fail, it's a different "distribution".
now, this is the file missing from the Origin install:
SOUND\STREAMS\NEVER_HEARD_OF_IT.SNS
get it from any other install (maybe the one from your friend that got the STEAM version?), it's just a little bit above 7MB, and drop it in that folder...that's it!, no more crashes due to that sound fail on Origin
As far as the game goes, same thing as Origin, no need to switch between them other than to avoid the file fail :P , DLCs look the same (showing the "not available" message), but all of them are "on disk" on both versions, the store closed long ago but the DLCs can be unlocked by using a savefile modifier program that it's around, so, you can still use all of them
this might be true, but only helps for people that can't even launch the game at all, which is not this case (game works but crashes when the game tries to load said track, Origin problem as it seems)
BTW, I didn't need to set any compatibility mod or "run as admin" option for this game to work (win 7 x64 here), I only needed it for the Origin version of Mass Effect (can't run otherwise, needed to run since it rely on some files), STEAM version works without this issue, too.
