Hello CoreAudio community,
I would like to notify the applications/HAL when the channels' name of my
CoreAudio HAL plugin has changed.
I try to do it the same way which works for the controls but no success; Audio
MIDI Setup doesn't update the channels' name.
Note: Applications only update the names when the number of channels has
changed.
I tries this:
CADispatchQueue::GetGlobalSerialQueue().Dispatch(false, ^{
AudioObjectPropertyAddress theChangedProperties[] = { {
kAudioObjectPropertyElementName, kAudioObjectPropertyScopeInput,
kAudioObjectPropertyElementWildcard }, { kAudioObjectPropertyElementName,
kAudioObjectPropertyScopeOutput, kAudioObjectPropertyElementWildcard } };
SA_PlugIn::Host_PropertiesChanged(m_SA_Device.GetObjectID(), 2,
theChangedProperties);
});
Is someone know how I should do to notify applications/HAL that the channels'
name has changed?
I also noticed that Logic Pro seems to not care about channels' name; I mean it
doesn't display the name provided by theplugin.
But Reaper properly display them.
Thanks a lot for your help,
Bertrand
