[Mathieu Trudel-Lapierre <mathieu.tl@xxxxxxxxx>]

Public bug reported:

When on Ubuntu Touch, HSP consistently fails to route any audio to the
paired audio device.

bluez-test-device create <BT address>
bluez-test-audio connect <BT address>

The above should create and pair a detected (in discoverable mode)
bluetooth device, by default setting it up for HSP.

The following excerpt from syslog on my mako shows the issue, with a
bluetooth headset device failing to bring up HSP -- pulseaudio can
acquire the first transport, but never release it:
