Droid 4 bluetooth audio through Alpine CDE-133BT

[Approve]

I just finished installing an Alpine CDE-133BT head unit but I cannot hear any audio.

The phone has no problem connecting and the head unit shows the track info of the current song. I'm also able to change tracks and pause/play; there's just no audio. I tried 3 different music applications - Play Music, Verizon's My Music and Winamp - experiencing the same issue with all. I tried turning off the metadata that was described in this post (Droid 4 and car Bluetooth music streaming) with no luck.

Any ideas? Thanks

EDIT - Tried it with my old Droid 2 Global. Same issue...

Not to be a smartass but I like to start simply is the media volume all the way down on your phone?

Check ALL Audio volumes first on both the phone and the radio. check pages 202 to 25 of the radio manual for more info on the volume and audio setting.
