<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">bluez5-device: use correct RTP payload type
If one device tries to use PulseAudio to send audio over A2DP to another
device with bluez-alsa, that doesn't work because PulseAudio uses an
incorrect RTP payload type and bluez-alsa checks that the RTP payload
type is correct. According to the A2DP spec, the payload type should be
set to a number between 96 and 127.
