Crate volumecontrol_linux 

Linux PulseAudio volume control backend.

This crate exposes an AudioDevice type that implements volumecontrol_core::AudioDevice. It exists primarily as an implementation detail of the volumecontrol crate, which selects the correct backend automatically. If cross-platform support is not a concern you may depend on this crate directly.

When the pulseaudio feature is not enabled every method returns AudioError::Unsupported, which allows the crate to compile on any platform without the PulseAudio development headers.

Example

use volumecontrol_linux::AudioDevice;
use volumecontrol_core::AudioDevice as _;

fn main() -> Result<(), volumecontrol_core::AudioError> {
    let device = AudioDevice::from_default()?;
    println!("{device}");  // e.g. "Built-in Audio (alsa_output.pci-…)"
    println!("Current volume: {}%", device.get_vol()?);
    Ok(())
}
