[Bug] ASIO broken with 0.17.1

[nico-franco-gomez]

I was going to update to CPAL's latest version (as of today 0.17.1), but I noticed that the ASIO code stopped working in several ways when compiling my project. Some struct properties and functions were renamed, some objects do not exist anymore.

Issues from the compiler:

error: could not compile `cpal` (lib) due to 3 previous errors

I guess my first reaction would be to ask how such a compile-time error can happen in the official release? Are maybe some maintainers for ASIO needed at the moment? I could try to help in there if it's a matter of human resources.

That is strange. Recently there have been a few contributions to ASIO and the CI passes fine. Would be appreciated if you could look into it what’s happening.
