pactl list output

I have my Android phone paired to my Fedora 26 machine via Bluetooth.

I am trying to play from a music app on the phone to PA on the Fedora machine.

While it basically works, I am getting a lot of stuttering.  When this
stuttering happens the following can be found in a "-vvvv" log output:

As you can see, I am using the audio in the HDMI adapter in this machine which
is a:

00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen
Core Processor Integrated Graphics Controller (rev 06)

I've attached a "pactl list" output.

Any ideas would be much appreciated.
