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.DeviceInterface.Type deviceInterfaceType | ( | ) |
Get the Solid.DeviceInterface.Type of the AudioInterface device interface.
- Returns:
- the AudioInterface device interface type
- See also:
- Solid.DeviceInterface.Type
| 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.AudioInterfaceTypes
| 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
