Línea de trabajo

Start by reading the issue’s ASIO build configuration and how backend selection handles unavailable devices; the issue names no source files or tests. The requested behavior is to let an application use WASAPI when ASIO setup fails and expose an error for debugging. Done means the issue’s fallback scenario can run without ASIO and the failure is diagnosable.

Descripción

host - asio

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.
