Although I've never seen this with Rivendell, I've seen it elsewhere and here 
might be the culprit:

If you are trying to play more than one audio file out through one sound card 
channel, sometimes things like this will happen unless care is taken.

The problem is when the setup is having the sound card hardware itself do the mixing of 
the two streams.  In this case you have to be careful that both streams are the same 
audio format (bit rate, sample rate, codec type, stereo/mono, etc.), especially the 
sample rate.  This is because the card can only do one of these formats at a time per 
output (sometimes per card, depending on the card).  Rivendell tends to force you to 
settle on one sample rate, so this is probably not the problem, but I'd look at the file 
format settings between to audio files known NOT to be able to seque from one to another 
(which would also have your "ignore End markers" symptom).  Again Rivendell's 
rdimport tends to keep you from making this mistake which is why I've never seen it with 
Rivendell, but perhaps you broke the rules somehow.

I've had an issue crop up at one of the stations I contract to where some
cuts will have End Markers set up, but when played back on RDAirplay it'll
ignore the end marker.  If the operator isn't paying attention there can
sometimes be a few seconds of dead air before the cut completely ends and
Airplay moves to the next one.  It seems to be rather arbitrary too, it only
happens to some cuts and I don't see any reason why.

Anybody seen this before?
