Issues with BT audio playback on denim. How to go back to cyan?

[ArgaVargen]

I have exactly the same issue with "glitches" in bluetooth car streaming with my new Lumia 640.

Also noticed it helps to switch off Wifi.

It would be nice with a feature in "car mode" to optionally switch off Wifi.

Same here with 640xl connect to philips ced1500bt.
Play with xbox music, or other music player app still same.
I though my sdcard.
