PortAudio Error [-9999]: Unanticipated host error

[goesjon]

Hello,

I complied playrec for Octave v6.3.0 and Windows 10 with portaudio v19.7.0 and ASIO SDK v2.3.3. The compilation was successful (I got the playrec.mex file). I have the following devices available (result of the playrec('getDevices') command):

deviceID = 0, name = ASIO4ALL v2, hostAPI = ASIO
deviceID = 1, name = Realtek ASIO, hostAPI = ASIO

When I run the following command for initialization:

playrec('init',48000,1,-1)

I get the following error message:

error: playrec: Init failed to open PortAudio stream
{PortAudio Error [-9999]: Unanticipated host error}

When I ignore this error message and just run the initialization command again, I do not get the error again and I successfully initialize the device. The device after that works perfectly fine. I seriously do not understand why???

Can somebody please help me? How can I resolve this error?

Thank you very much.

Best regards

I found a workaround (unfortunately not a real solution):

try
playrec('init',48000,1,-1)
catch
playrec('init',48000,1,-1)
end_try_catch
