Когда я пытаюсь получить список доступных аудиоустройств, подобных этому.
LyncClient client = LyncClient.GetClient();
foreach (Device dev in client.DeviceManager.AudioDevices)
{
//Do something
}
Я получаю сообщение об ошибке Exception has been thrown by the target of an invocation.
"Unable to cast COM object of type 'System.__ComObject' to interface type
'Microsoft.Office.Uc.IAudioDevice2'. This operation failed because the QueryInterface
call on the COM component for the interface with IID '{86B3E5FE-4635-4C1E-
A725-C80B71D04984}' failed due to the following error: No such interface supported
(Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."
