Im changing original HL1 sounds for some custom ones but i have noticed that, despite the fact the NPCs emit the audios, they dont open their mouths to speak it.
Im using .wav sounds with 11khz, 22khz and 44khz, 8bit and 16bit. Im also using cue points on them.
Is this related to some arquive responsable for lip sync or im missing some audio config?
