AlliedModders - [CS:GO] Does not allow sound overlay

Hello Guys!

I'm having problem when I try to put two plug-ins/addons of sound on my server in CSGO.

Quake Sound 3.0
AbNeR Round End Sounds V4.0.1: Add songs at the end of each round.

Both work fine, the problem is that when the sound of one is playing, and the other is activated by something in the game, one interrupts the other.

Example: When the round ends, the music of the addon "AbNeR Round End Sounds" starts to play, but if by chance, a player kills someone and activates some sound of the "Quake Sound", the music is then interrupted.

I don't know if this is a limitation of CSGO, not overlaying sounds, because I used the same addons in CS Source, and that didn't happen.

If anyone has any answers I would be very happy. thanks.
