Hi Ed, Hum, not cool ;( Yes I tested with HALLab which properly receives the notifications. Do you know which others notifications I could use to "force" the Application/HAL to ask again channels' name? Otherwise I'll have to inform users to relaunch the application by itself ;(

You can send as many notifications as you want, but it won’t do anything if nobody is listening for them. -Ed P.S. You can use the notification view in HALLab.app to see if you’re actually sending them correctly.

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.
