No sound with mp3. Uninstall (RevoPro) and reinstall didn't solve it. Strangely (or not), the files converted to flac are about 30% the size of the wv files, e.g., 140 mb to 40 mb. Makes me wonder if the audio is being stripped or not picked up on the conversion.
Afterthought: Must be something with the wv files, since the Oppo should play them and isn't. But then why they play in foobar but the flac's don't, is a puzzle.
