When I select the Phantom Power button in ffado-mixer, the log message "18:41:08 audiofire: set /PhantomPower to 1" is output, and the button stays depressed. However, the phantom power light on the audiofire does not light up, and the phantom power is not supplied to the microphone. When I select Edit -> Refresh Current Panels, the phantom power button is no longer depressed.\r\n\r\nI have also tested with the following script, which is slightly modified from one found on ticket #136:\r\n\r\n{{{\r\n#!/usr/bin/ruby\r\nrequire 'dbus'\r\nbus = DBus::SessionBus.instance\r\nff_service = bus.service("org.ffado.Control")\r\nff_service.introspect\r\nff_manager = ff_service.object("/org/ffado/Control/DeviceManager/001486af2ef4ae91/PhantomPower")\r\nff_manager.introspect\r\n\r\nff_mixer_phantom = ff_manager["org.ffado.Control.Element.Discrete"]\r\nprint "Old value: "\r\np ff_mixer_phantom.getValue\r\nputs "Setting new value 1"\r\nff_mixer_phantom.setValue 1\r\nprint "New value: "\r\np ff_mixer_phantom.getValue\r\n}}}\r\n\r\nWhen I run that script, I get the following output:\r\n{{{\r\nOld value: [0]\r\nSetting new value 1\r\nNew value: [0]\r\n}}}\r\n\r\nI am using the newly released ffado 2.1.0. I am not sure of the firmware version (Is there a way to see this on Linux?), but I would have updated it late last October. bug closed major devices/fireworks FFADO 2.1.0 fixed phantom power, audiofire4 Echo Audiofire 4
