Half-Life Opposing Force, I need to know which files are audio as i need to extract them to a sepera

I dont have a copy of Opposing Force anymore, but I believe all the audio files are just standard CDDA. Just use something like Nero and choose 'save track' from the cd-recorder menu. Save all the audio tracks in the list to your hard drive as either mp3 or wav files. I think this is the answer you were looking for.
