BASS_WASAPI_Init fails, error code -1
« on: 16 Aug '17 - 16:43 »
My audio recording application (Windows native C++) has been working properly with no issues for months. Now BASS_WASAPI_Init is failing, BASS_ErrorGetCode is returning -1, and I'm not aware of any changes to my system that would cause this. I suspect a Windows update, but I haven't been able to confirm this.

I tried recording in Reaper using WASAPI and that was also failing, I got Reaper working by reinstalling my audio device driver and setting the input and ouput sample rates in Windows control panel to the same value. Now I can successfully record and playback in Reaper using WASAPI.

However, in my application BASS_WASAPI_Init is still failing, and -1 isn't very useful. I could use some troubleshooting suggestions. Any way to get the inner HRESULT from WASAPI system?

I will send you a debug BASSWASAPI version to get more info on what's happening.

Thanks for your help.

The issue seems to be caused by Kaspersky antivirus (Endpoint Security 10 with all the default options).

If enabled I can replicate the issue 100%. I haven't been able to replicate the issue yet with it disabled.

I have not bothered to investigate if I can get bass working with Kaspersky enabled by changing settings in Kaspersky. My solution is to uninstall Kaspersky and use MSE instead.
