Hi there.. Im Joe. Working on a Multicast Application using wpf with C# and i use Directx Directsound. While setting the CooperativeLevel to the Device.. i create a forms.control and passed as the Hwnd parameter, rather i used also the USER32.GetDesktopWindow();. i''m able to successfully Multicast my audio. the Problem i face here is.. while the window in minimized or if any other window is enabled on the receiver side.. the audio is muted.. i can hear the audio only the particular window is enabled. Rather i need the audio, although the window is minimized.

Please give me some suggestion to overcome this issue.

Thanks in Advance.

推荐答案

我为这个问题找到了解决方案.我错过的要点是添加回放BufferDescription属性.
BufferDescription.GlobalFocus = true;即使窗口最小化也可以播放音频.

快乐编码.

I got a solution for this problem.. The point i missed out is to add a playback BufferDescription property.
BufferDescription.GlobalFocus = true; enables the audio to play even the window is minimized.

Happy Coding.
