[Question] play without blocking main thread

[YXL76]

Thanks to neon, I can use Rodio in nodejs.
When using 0.11.0, it can play audio in background and do not block the process.

use neon::prelude::*;
use std::{fs::File, io::BufReader};

fn load(mut cx: FunctionContext) -> JsResult<JsUndefined> {
    let url = cx.argument::<JsString>(0)?.value();

    let device = rodio::default_output_device().unwrap();
    let sink = rodio::Sink::new(&device);

    let file = File::open(url).unwrap();
    sink.append(rodio::Decoder::new(BufReader::new(file)).unwrap());

    Ok(cx.undefined())
}

register_module!(mut cx, { cx.export_function("load", load) });

But when using git version, there is no sound unless add sleep_until_end. However, the main thread is blocked.

use neon::prelude::*;
use std::{fs::File, io::BufReader};

fn load(mut cx: FunctionContext) -> JsResult<JsUndefined> {
    let url = cx.argument::<JsString>(0)?.value();

    let (_stream, handle) = rodio::OutputStream::try_default().unwrap();
    let sink = rodio::Sink::try_new(&handle).unwrap();

    let file = File::open(url).unwrap();
    sink.append(rodio::Decoder::new(BufReader::new(file)).unwrap());

    // play sound only if uncomment the next line
    // sink.sleep_until_end();

    Ok(cx.undefined())
}

register_module!(mut cx, { cx.export_function("load", load) });

Therefore, my question is whether there is a way to play sound without blocking main thread.
