So after I compiled a map i'm working on everything works fine except weapons don't make sounds (including grenade throw sound) neither do doors. The strange thing is that if I throw a plasma grenade after it explodes the sounds comeback but go away soon after. This is really strange and has never happened to me before. Anybody got any ideas on how to fix this?

When you create SFX for weapons, make sure to use the right settings for them.
For example: if you're compiling firing sounds, open the compiled .sound in Guerilla and set the "class" to "weapon_fire". If it's a reloading sound, the class should be "weapon_reload" and so on.

You can view the sound\sfx\weapons directory as reference in order to understand the right settings for the different kinds of sounds that will have a weapon (including grenades). And also, make sure you're compiling the sounds in mono and in Xbox format (you can download the Xbox codec right here: https://haloce3.com/downloads/misc-files/xbox-codec-updated-3264bit/ )

Natively, Halo CE doesn't recognize the 44Khz quality for weapons sounds, but you can use a "trick" in order to emulate the 44Khz and gain some audio quality: http://forum.halomaps.org/index.cfm?page=topic&topicID=48948

And as for the .wav files, they must be always in 16-bit sample rate and mono format (at least for the weapon sounds). I hope this express tutorial can help you.
