I can't get wav or mp3 to play either.
When I do the hello_audio test, it works through the headphone, but not HDMI (I think my TV sets itself to DVI) But then I can't get any sound from a wav file, and when I load up the media player, I can add a wav file to the playlist, but the sound is set on mute, and it won't play. Also using the aplay command doesn't work.
I'm stuck, what am I missing. Please someone help
