Detailed Description

template<typename pin_t>
class dx::coreaudio::server::device< pin_t >

streaming device representation of dxd kernel user client

CoreAudio server plugin.

In contrast to the hierarchical dx device tree design the device keeps a list of all pins and all streams to better reflect the CoreAudio architecture.

static OSStatus deviceSampleRateChanged(AudioObjectID inObjectID, UInt32 inNumberAddresses, const AudioObjectPropertyAddress* inAddresses, void* __nullable inClientData) { cout << "callback" << endl; return noErr; }

AudioObjectPropertyAddress address; address.mSelector = kAudioDevicePropertyNominalSampleRate; address.mScope = kAudioObjectPropertyScopeGlobal; address.mElement = kAudioObjectPropertyElementMaster;
