If ASIO fails to load, the build crashes, but I need it to be optional #1083
Description
Hello,
I am developing an audio application and I need to have ASIO support for low-latency. So, considering that, in my cargo.toml I have "cpal = { version = "0.17.0", features = ["asio"] }". However, if it fails to download SDK or ASIO doesn't get properly loaded for whatever reason, the app just crashes and never runs. Which is not ideal for me.
Errors in my example:
error: IO error for operation on C:...\asio_sdk\host: The system cannot find the path specified. (os error 3)
error: IO error for operation on C:...\asio_sdk\host/pc: The system cannot find the path specified. (os error 3)
error: IO error for operation on C:...\asio_sdk\common: The system cannot find the path specified. (os error 3)
I don't know how this error happened, I already had ASIO SDK installed because I use FL Studio, but the folder isn't named "asio_sdk", it is "ASIOSDK". And because of that, it crashes, but I would like it to just fallback to WASAPI for example and log errors for debugging. ASIO isn't required for my application.
I know how to fix this error btw, I just set "CPAL_ASIO_DIR" env variable myself, that's not an issue.
Any ideas on how I can achieve this at the moment? Or if it might be possible in the future? Thanks for taking the time to read this. Any help is greatly appreciated.
