Línea de trabajo

Start by reading the Linux device enumeration path used by HostTrait::devices() and compare its behavior with the reported ALSA device list and JACK connection warnings. The report includes a Rust example and CPAL 0.13.4 output, but does not identify the failing component or expected behavior. Done means determining whether device listing is failing and documenting or fixing the cause.

Descripción

host - alsa platform - linux

CPAL Version: 0.13.4
Distro: Garuda Dragonized Linux

I don't really know what's causing this issue, but here's the code I've tried and the output of it

use cpal::default_host;
use cpal::traits::{DeviceTrait, HostTrait};

fn main() {
  let host = default_host();

  println!("{:?}", cpal::available_hosts());

  let devices = host
    .devices()
    .map(|it| it.map(|it| it.name()))
    .unwrap()
    .collect::<Result<Vec<_>, _>>()
    .unwrap();

  println!("{:?}", devices);
}
