I'm trying to add a music file via the 'music' key to worldspawn. When the level loads, the console reads "No data chunk in sound/junglist/blah.wav" and the file does not play. The file is in 22khz 16bit stereo just like every other q3 music track, so I don't get what's going on. It plays fine in Winamp and sndrec32, so the file itself should be good.
You were right. It didn't like my wav file exported directly from Reason, either. So I downloaded Audacity, opened the wav, resaved it... and it worked. Good old free software!!
