[Can't replicate] 2-sided poly sounds

[The Ultimate DooMer]

Has anyone else noticed that the sound sequence for a 2-sided polyobject plays much quieter than for normal polys?

I moved the control sector closer to the location and nothing happened.

I also turned up the sound's volume (by putting in a louder ogg) and nothing happened.

Putting the sequence on just 1 side of the poly instead of all 4 resulted in the sound disappearing altogether.

I tried a different sequence and the same thing happened.

Even running a script for opening the door (after removing the sequence from the poly) and using activatorsound didn't work, until I put the command in 5 times. So I've currently got this method in as a workaround, but I think it's a bug, as shouldn't the sound work properly like a normal poly?

Please post an example wad. Here is one that sounds just fine (for Hexen). What does it need to be like to sound not fine?
