"System.NullReferenceException" in AudioSwitcher.AudioApi.CoreAudio.dll #2162

Closed EverBS2014 closed 6 years ago

EverBS2014 commented 6 years ago

I'm using VS2017 on Windows 10. My WPF application is using the lastest version of this API and has a Realtek onboard sound card

I want to set the volume of the windows setting to max like that:

 CoreAudioDevice defaultCaptureDevice = new CoreAudioController().DefaultCaptureDevice;
 defaultCaptureDevice.Volume = 100;

So far it's working but after the first call my CPU usage is increasing and I constantely receive this message in the VS2017 output window:

"System.NullReferenceException" in AudioSwitcher.AudioApi.CoreAudio.dll "System.NullReferenceException" in AudioSwitcher.AudioApi.CoreAudio.dll "System.NullReferenceException" in AudioSwitcher.AudioApi.CoreAudio.dll "System.NullReferenceException" in AudioSwitcher.AudioApi.CoreAudio.dll "System.NullReferenceException" in AudioSwitcher.AudioApi.CoreAudio.dll "System.NullReferenceException" in AudioSwitcher.AudioApi.CoreAudio.dll ....

It's not stopping. What is wrong?

Can you open it in the Api project? https://github.com/xenolightning/AudioSwitcher

With specific details on the version, and OS version?

Thanks.

I have downloaded your link, but which project do I have to start? I tried to build all with VS2017 but I get several errors about a api.pfx file

I'm using AudioSwitcher.AudioApi.CoreAudio. 3.0.0.1 And I have to problem with Win 7 and Win 10

My WPF application has as target framework .NET 4.5.2

Sorry. I meant open the issue in the Api Project. This project is for the desktop application.

Can you try using the latest version 4.0 alpha build instead of v3.0.0.1?
