Note: Not all sound files seem to play correctly in the game (although all play in the editor). To be safe, use the formats used by Bethesda (thanks to random name) :
"Cr" and the "Fx" folder
Windows PCM (.wav)
22050 kHz, 16-bit, Mono
Lower qualities work as well, e.g. 8,000 kHz; 8 Bit; Mono. Used e.g. in my "The Regulars" mod for Tavern music.
