Default Unable to use bluetooth audio

Hi all,

I'm having an issue with my HTC One M8 and using it to stream audio over bluetooth. On my last phone (VZW GS4), when I connected it to my Flex's stereo (Sony SYNC with nav), it would list in the bluetooth pairing as connected to phone & media audio. However now on the HTC One, it only shows phone audio.

I have searched all over and couldn't find any info on this issue and there doesn't seem to be a setting in the stock ROM to set it up. The system still works with the phone when using it for phone calls.

Any ideas?

Cheers,
