Matthew, That was my original email, but no success. The BT adapter in the raspberry pi 3 I was using does not show any SCO packets during the call. I've moved to an external BT device and I haven't had any issues with it. When the call is made, your screen should be *flooded* with SCO packets. If not, then you are experiencing the same problem that I've never found a solution to. Good luck, Jason On Wed, Jul 27, 2016 at 4:09 PM, Matthew Waddell <matt@xxxxxxxxxxxxxx> wrote: > Hi, > > I am trying to configure HFP to allow in-call audio to be routed through my > PC's audio card.
