Shared object "libasound.so.2" not found

Would love to see support for pipewire``pulseaudio and portaudio just to name a few.

[talwat]

lowfi does support pipewire & pulseaudio? It uses an external crate called rodio which relies on the ALSA API that is supported by lots of different audio backends via pulseaudio-alsa for instance. Supporting the native API of other backends is firstly not within lowfi's control and secondly just pretty unnecessary.

I'm closing this issue as invalid, but if your audio just isn't working then feel free to reopen it.

From portaudio's own website:

It lets you write simple audio programs in 'C' or C++ that will compile and run on many platforms including Windows, Macintosh OS X, and Unix (OSS/ALSA)

So yeah, really not sure what this issue is about.

[pfr-dev]

Ok, my fault, I should have been clearer with the actual issue.

The build fails on both VoidLinux (where I have pipewire configured) and on NetBSD (Portaudio).

  The system library `alsa` required by crate `alsa-sys` was not found.
  The file `alsa.pc` needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.
  The PKG_CONFIG_PATH environment variable is not set.

  HINT: if you have installed the library, try setting PKG_CONFIG_PATH to the directory containing `alsa.pc`.

error: failed to compile `lowfi v1.5.3`, intermediate artifacts can be found at `/tmp/cargo-installFOLnsz`.
To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.

I suppose I'd like to be able to use this without needing to install alsa

However, I tested after installing alsa-plugins-pulse and alsa-lib on NetBSD and the cargo build succeeds but the resulting binary complains with:

~ λ lowfi
lowfi: Shared object "libasound.so.2" not found

So, again, I apologise for the lazy first post, but perhaps we can reopen this issue and give it a new name?

[talwat]

Ah I see now. Could you try installing pulseaudio-alsa instead of alsa-plugins-pulse? I'm not sure if they're entirely the same on BSD however.

[talwat]

It might also be a BSD issue unfortunately, the sound crate I'm using doesn't support BSD's.
