`libasound.so.2` is now loaded with `libloading` when the output device is created, rather than being linked at build time via `alsa-sys`. This means: - A binary using tinyaudio can start on a machine without ALSA installed (minimal containers, headless servers). Previously the dynamic loader failed before `main` ran. Now `run_output_device` returns an error instead. - Building no longer requires `libasound2-dev` / `pkg-config`. The ALSA call sequence (hw/sw params, S16_LE, period/buffer sizes, recover loop) is unchanged; only the way the symbols are resolved differs. MSRV is bumped to 1.71 as required by `libloading` 0.8. The previous `rust-version = "1.56"` was already stale since `dep:` feature syntax needs 1.60. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

There was a problem hiding this comment.
note: we can get away with a lower MSRV if we use an older libloading. Up to you!

What
The
alsabackend now loadslibasound.so.2at runtime withdlopen(vialibloading) instead of linking it at build time throughalsa-sys.Why
A binary linked against
libasoundcannot even start on a machine without ALSA (minimal containers, headless CI runners, servers, etc): the dynamic loader fails beforemainruns. With this change the program starts fine everywhere, and onlyrun_output_devicereturns an error such as:A side benefit: building no longer needs
libasound2-dev/pkg-config(the CI apt install is left alone sincepulsestill needslibpulse-dev).Downside: more complex code
