I've separated sfx and music into two channels, so one can adjust sfx and music level independently. Channel with music is fine but I have encountered problems with sfx channel. Every sound that plays in that channel cancels out everything else that is played at the moment. For example, if I jump when somebody shoots, sound of shooting is interrupted and jump sound is the only thing in the channel until it plays completely or gets interrupted by something else like another shot. How do I fix it?
