Issues building in 32bit mode

[andyclegg]

I can successfully build the driver in Visual Studio 2019 targeting x64, but when I set the target platform to Win32 in order to support a 32-bit machine, I get a whole load of linker errors. Any input into getting this building would be greatly appreciated. Thanks

I never built a win32 variant. I just tried it and get the same symptoms, so this isn't just your machine. When you installed WDK, was there an option to install both x86 and x64 variants?

[andyclegg]

Thanks for trying - was good to know it wasn't just me! After trying a bit more I got it to compile and install by making two changes -

1. Added C:\Program Files\Windows Kits\10\Lib\10.0.19041.0\km\x86*.lib to Linker>Input>Additional dependencies
2. After building, manually edited Scream.inf to replace NTAMD64 with NTx86 in two places.

This installs successfully, however I've now come across another issue - the sound quality is really bad. It sounds really clipped and distorted. I wonder if there might be any places in the code where it uses architecture-dependent variable sizes, such that a 32-bit sample might now be stored in a 16-bit variable?

[andyclegg]

After more testing, I changed Scream to use Unicast and the sound quality improved a lot. I now suspect that it's VirtualBox dropping packets.

Related to previous, one more change I needed for a successful install was to substitute in the x86 version of devcon.exe.

[gabrielstedman]

The following enabled me to build a x86 release from a x64 machine and the inf sections missing to be able to install.
Thank you @andyclegg for your useful notes.
