[Preferences/Sound] set file filter for picker

Preferences/Sound Will display all files to pick from to get a sound from, even files it does not support. It will show "not an audio file" then.

On another similar thing, i wanted to use a video as a soundsource which is not allowed, should this be changed? (I.e automatically strip out the audio track and save it somewhere to use)

Also, it complained that my .opus files were not audio files, is the preferneces thing using something other than the media kit? MediaPlayer has no problem playing the opus files.

for the .opus file:

They are set to BEOS:TYPE video/ogg, when i switch them to audio/ogg sounds then has no problem to play them.

The problem here seams to be that video/ogg gets assigned to the file even though the file has no video track at all, thus making this particular mimetype unsuitable for detection of whether a video track is contained or not.
