In the global/ambient.scr only 6 aux are mentioned...
I'm using a 7th aux and it's working..so far.
I had a crash in my map but dunno what the prob was...I have a sentry doing the patrol routine (waypoints, etc) and NO pathnodes. He killed me once and the game crashed. The moment he killed me (and the computer was crashing) I could hear the last bullet sound looped...and it crashes.
Or 1) was a sound problem (too many stuff)
Or 2) As he don't have pathnodes, he was having some kind of problem going back to the routine.
I putted pathnodes all over the places he suppose to "visit" and the game it's not crashing anymore (when he kills me).
But the fact that I'm using 7 aux channels (one at a time) might be the problem...I've been testing a lot and it's not crashing so far...
Well there is a limited number of channels you can use, I think up to aux8 and then another few like 'suspense' and 'normal'. Check the ambient sounds and music tut, I think that one has a complete list.
