G'day Bill, You said you aren't hearing any other sounds while an explosion sound plays out? Are you sure about that? With COW on Linux, sounds are layered using SDL so that multiple events are mixed together over time. If NetrekXP mixes sound, perhaps lowering the amplitude of the explosion sound will make the mix sound better. I've skill with sound editing ... but I'd need to know which way NetrekXP works before I do anything to them. -- James Cameron mailto:quozl at us.netrek.org http://quozl.netrek.org/
