In order to figure out if the "raw" audio contained within the wav container is actually DTS, wavparse calls the typefinder helper except that means it runs all typefinders. Since it only cares about checking for DTS, we should only run the audio/x-dts typefinder (if present). Commit 858e516 did not really fix things. Use the new type helper with the caps to fix this.
