Depending on what kind of audio programming you intend to do, it should be possible to use Rust or other alternative programming languages. Your mileage may vary, depending on the dependencies of what you intend to build. If you want to interface with your operating system's low-level audio libraries you should be able to do that from any language that can interface with C. I was able to use Ada together with ALSA on Linux in this way. In this case the code responsible for generating the sound was in Ada, and the code for interfacing with the audio hardware (via ALSA) was in C. If you intend to write audio code for bare metal, you should be able to use any programming language your target hardware's toolchain supports. I've heard of people using alternative languages to write VSTs. I'm not an expert in this area, however theoretically you should be able to do something similar to the above as long as you have a good way to interface with C/C++ code.
