Class
HitakiSndMotu
Description [src]
class Hitaki.SndMotu : GObject.Object {
parent_instance: GObject
}A GObject-derived object for sound unit of MOTU FireWire series.
The HitakiSndMotu is an object class derived from GObject with protocol
implementation for Mark of the Unicorn (MOTU) FireWire series supported by ALSA firewire-motu
driver (snd-firewire-motu).
Constructors
hitaki_snd_motu_new
Instantiate HitakiSndMotu object and return the instance.
Instance methods
Methods inherited from HitakiAlsaFirewire (4)
hitaki_alsa_firewire_create_source
Allocate GSource to handle events from ALSA HwDep character device.
hitaki_alsa_firewire_lock
Lock kernel driver bound to the associated ALSA HwDep character device so that it is prohibited to start packet streaming.
hitaki_alsa_firewire_open
Open the special file for ALSA HwDep character device.
hitaki_alsa_firewire_unlock
Unlock kernel driver bound to the associated ALSA HwDep character device so that it can start packet streaming.
Methods inherited from HitakiMotuCommandDsp (1)
hitaki_motu_command_dsp_read_float_meter
Read cached data of meter information for command DSP models.
Methods inherited from HitakiMotuRegisterDsp (2)
hitaki_motu_register_dsp_read_byte_meter
Read cached data of meter information for register DSP models.
hitaki_motu_register_dsp_read_parameter
Read cached parameter for register DSP models.
Properties
Properties inherited from HitakiAlsaFirewire (6)
Hitaki.AlsaFirewire:card-id
The numeric identifier for sound card.
Hitaki.AlsaFirewire:guid
Global unique identifier for the node in IEEE 1394 bus.
Hitaki.AlsaFirewire:is-disconnected
Whether the sound card is unavailable. It becomes FALSE when the sound card is removed or
driver is unbound to it. Then the owner of this object should call
g_object_unref() as quickly as possible to release ALSA hwdep character device.
Hitaki.AlsaFirewire:is-locked
Whether the associated unit is locked or not to start packet streaming.
Hitaki.AlsaFirewire:node-device
The name of node device in Linux FireWire subsystem which owns the unit; e.g. fw1.
Hitaki.AlsaFirewire:unit-type
The type of sound unit.
Signals
Signals inherited from GObject (1)
GObject.Object::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
Signals inherited from HitakiMotuRegisterDsp (1)
Hitaki.MotuRegisterDsp::changed
Emitted when MOTU register DSP models transfer events by messages in the sequence of
isochronous packet. The event consists of encoded data. The most significant byte is the
type of message. The next two bytes are two identifiers. The least significant byte is
value. The meaning of identifier 0, 1 and value is decided depending on the type. For
detail, see sound/firewire/motu/motu-register-dsp-message-parser.c in Linux kernel.
Signals inherited from HitakiQuadletNotification (1)
Hitaki.QuadletNotification::notified
Emitted when the target unit transfers notification.
