Couldn't get BlueALSA PCM: Rejected send message

It's quite possible that that part is missing from the documentation... The problem is with D-Bus configuration. Make sure that you've got a file like this:

> cat /etc/dbus-1/system.d/bluealsa.conf
  <policy user="root">
    <allow own_prefix="org.bluealsa"/>
    <allow send_destination="org.bluealsa"/>
  </policy>
  <policy group="audio">   <!-- allow user in "audio" group to connect with bluealsa service -->
    <allow send_destination="org.bluealsa"/>
  </policy>

  <!-- this is optional -->
  <policy user="myuser">   <!-- allow user "myuser" to connect with bluealsa service -->
    <allow send_destination="org.bluealsa"/>
  </policy>
  <!-- this is optional -->

</busconfig>

It might happen that the rules will not be applied automatically, so in that case reboot.
