I am using Visual Micro plugin for Visual Studio and everything has been working fine with the Teensy 4.1 - love it. That was until I attempted to include the audio library. I get an impossible constraint violation when building with the audio library included. The compiler output is attached. The source code is at https://github.com/bitdog-io/restraining_bolt/tree/pre-release/src. I first though that the public library might be out of date so I pulled from master on GitHub and replaced the one Visual Micro installed but I still get the error. I changed the build target to Teensy 3.6 and then to Teensy 4.0 and they both built successfully. I then switched to Teensy 4.1 as a build target and it failed again.

Thank you for your time,
Vince

I had to reorganize my project to make it suitable for Arduino and it complied. I used the new project layout for Visual Micro and it compiles as well now. Thank you for your quick response.
