## Method Documentation

__init__ | ( | self, |
|  | QObject | backendObject
| ) |  |  |

Creates a new AudioInterface object. You generally won't need this. It's created when necessary using Device.as().

Parameters:

  | backendObject | the device interface object provided by the backend

See also:
  Solid.Device.as()

Solid.AudioInterface.AudioInterfaceTypes deviceType | ( |  | self ) |

Retrieves the type of this audio interface (in/out/control).

Returns:
  the type of this audio interface

See also:
  Solid.AudioInterface.AudioInterfaceType

Solid.AudioInterface.AudioDriver driver | ( |  | self ) |

Retrieves the audio driver that should be used to access the device.

Returns:
  the driver needed to access the device

See also:
  Solid.AudioInterface.AudioDriver

QVariant driverHandle | ( |  | self ) |

Retrieves a driver specific handle to access the device.

For Alsa devices it is a list with (card, device, subdevice).

     QVariantList list = dev->driverHandle().toList();
     QString card = list[0].toString();
     int device = list[1].toInt();
     int subdevice = list[2].toInt();

The card entry sometimes can be converted to an integer, but it may just as well be the textual id for the card. So don't rely on it to work with QVariant.toInt().

For OSS devices it is simply a string like "/dev/dsp". Use QVariant.toString() to retrieve the string.

Returns:
  the driver specific data to handle this device

QString name | ( |  | self ) |

Retrieves the name of this audio interface.

The product name of the parent device is normally better suited for the user to identify the soundcard. If the soundcard has multiple devices, though you need to add this name to differentiate between the devices.

Returns:
  the name of the audio interface if available, QString() otherwise

Solid.AudioInterface.SoundcardType soundcardType | ( |  | self ) |

Retrieves the type of soundcard (internal/headset/...).

Returns:
  the type of soundcard

See also:
  Solid.AudioInterface.SoundcardType

## Static Method Documentation

Solid.DeviceInterface.Type deviceInterfaceType | ( |  | ) |

Get the Solid.DeviceInterface.Type of the AudioInterface device interface.

Returns:
  the AudioInterface device interface type

See also:
  Solid.DeviceInterface.Type
