[Pander <1926641@xxxxxxxxxxxxxxxxxx>]

As requested by a maintainer of FFADE, the output of the diagnose tool.
This is most likely to do with device rights for the user or group.

UPDATE: When I looked at the output of the diagnose tool, I see two
Firewire devices with different user/group rights. (The card in the
desktop has actually three places to add a FireWire cable, not two.)
When I plug in on the left connector, this user rights issue occurs. But
when I plug it into the middle, the issue is gone.

So this might nog be an issue for FFADO. I have another desktop with
FireWire and a DV camera. I notived also that the port I use there has
influence in how I can connect to the camera. Will test this later on
and add the findings here. Perhaps there is a convention or default
config to offer FireWire #0 only for root and #1 also for group audio?

Title:
  FFADO 2.4.4 only runs properly with sudo

Status in libffado package in Ubuntu:
  Triaged

Bug description:
  Starting FFADO 2.4.4 from the menu does not list a device and reports
  in the GUI the following error:

  Somehow the connection to the dbus-service of FFADE couldn't be
  established.

  and had the log message:

  logginghandler: Could not communicate with the FFADO DBus service...

  When starting FFADO from the command line with

  sudo ffado-mixer-qt4

  no error is reported and the sound device is listed and usable.

  Please, fix that the default/normal user that can change sound
  settings can also use FFADO directly when launching it from the menu.
