Hi! Did you try dev-branch of sipdotnet?

Hi! I have some problem with audio. I use dev branch. When i use phone.PlaybackDevice() i receive list with Count is 0. I wrote my implementation with Marshalling and turned to the linphone_core_get_sound_devices method, but i have the same result :(
I work on Windows 7x64 with Visual Studio 2015 Community.
What doing i wrong?

@FirsovMS Did you try Linphone client? Maybe it's #22 related. It seems that new liblinphone version (which the dev-branch uses) is buggy.

[dillipdala]

yes, i have tried from dev-branch of sipdotnet. but still getting same issue.

In Linphone Clinet it works perfect, and all devices defince correct. But in sipdotnet not. I try to use master branch, my soundcard define , call establish but microphone have no sound.

I noticed that the problem is related to LinphoneCore's veracity. When I use LinphoneCore 3.11.2-158-g4c291e2 - media devices are determined, but my interlocutor does not hear me. In the debug console, I received the error message: Could not set QoS flow, error = 87.
With other versions of LinphoneCore devices are not defined at all.

in the screenshot list of my devices from the device manager.

yes , i have tried code from dev-branch but audio is not working.

when i tried audio is working fine with code "https://github.com/bedefaced/sipdotnet" Master branch but here is no functionality available for chat message.

Yes! I have the same problem. I think this problem exists on mediastreamer2 dll's. After a lot of attempts, I came to the conclusion that there are some problems with the wasapi interface implemented in this library. At least for me, on LinphoneCore 3.11.2-158-g4c291e2 everything works with dev-brunch, except for the microphone.
I explicitly received a message in the debug console: 'Could not initialize the MSWASAPI audio input interface [80070057]'.
The latest original linphone windows client has the same problem.

Hi

anybody has solution?

[LunevNF]

No solution yet? How to work if cannot talk with people?

First of all, thank you very much for this solution.

But, same problem here.

Everything works fine with master.
Everything works fine with linphone-client (multiple versions).
But with sipdotnet-dev it does not transfer outgoing or incoming audio.

I would be happy to use sipdotnet-master, but I need to pause calls and other cool functions of sipdotnet-dev.

GetPlaybackDevices() and GetCaptureDevices() return empty.

Any ideas?? I've tried everything, I've even tried different versions of Visual Studio.
