in our custom UI based client we are using Desktop SDK with C# wrapper. We share audio using “StartSharePureComputerAudio()” call. It works on all test PCs we have.
Yesterday a customer reported the audio share feature not working on a PC using our client. We’ve not been able to identify any reason to explain why it is not working, i.e. the call does not return any error (it succeeds) but no audio is shared from that PC. We can hear audio locally on the PC, change volume, play audio with different clients. We checked the PC input/output volumes, mixer settings, devices (enable/disable state at driver level). But to no avail.
What’s puzzling is that we started the native Zoom client and audio sharing worked (Share screen → Advanced → Music or computer audio only). So I am wondering what may be different between the native Zoom audio only sharing feature and the SDK StartSharePureComputerAudio() method.
Maybe we’ve missed something in out implementation, but no idea on what.
Thanks for any suggestions on how to proceed for fixing this problem, or something to check to explain this.
