Windows 10 WASAPI interfering with ASIO

[dayvyg]

Hi All,

Just demoing Waveform 10 and like it so far. I have just one problem, getting the ASIO driver to work reliably. I get an "Error when trying to open audio device!" when I try to choose my ASIO audio device (Steinberg UR824). Strangely, if I select windows audio and then choose my device, save it and close the project. I can then open the project, change the audio device to ASIO and then it works. However, when I close and open the project again I have the same problem.

The Waveform10log shows the following:

So it seems that WASAPI wants to own the device and is not letting ASIO claim it.

I use both Reaper and Mixbus 32C and both work fine with this audio interface. However, Mixbus gives you the option to not install WASAPI support as this has been a problem for them in the past too.

If anybody has any ideas of a better fix for this then I'm all ears.

Windows 10 x64
Steinberg UR824 - 1.10.4.1 USB driver (I've reinstalled the driver with no improvement).

Thanks.
