       Type:  bug              |      Status:  new      
   Priority:  major            |   Milestone:  FFADO 2.0
    Version:  FFADO SVN        |    Keywords:           
Device_name:  Echo AudioFire4  |  
-------------------------------+--------------------------------------------
 Hardware is AudioFire4 with 4.8 firmware. FFADO is SVN r1259.

 Attempting to enable +48V phantom power feature on the AudioFire4 via
 DBus, does not enable the feature on the hardware unit:

 {{{

 132817716390: Debug (fireworks_control.cpp)[ 436] setValue: setValue to 1
 }}}

 Trying to fetch the value via DBus always returns 0 value:

 My Ruby language snippet to interact with DBus:

 {{{

 #!/usr/bin/ruby
 require 'dbus'
 bus = DBus::SessionBus.instance
 ff_service = bus.service("org.ffado.Control")
 ff_manager =
 ff_service.object("/org/ffado/Control/DeviceManager/00148608bd30a7b8/Mixer/PhantomPower")
 ff_manager.introspect
 ff_mixer_phantom = ff_manager["org.ffado.Control.Element.Discrete"]
 #print "Old value: "
 #p ff_mixer_phantom.getValue
 #puts "Setting new value 1"
 #ff_mixer_phantom.setValue 1
 print "New value: "
 p ff_mixer_phantom.getValue
 }}}
