CPal doesn't list mac speakers as an output device

[randomairborne]

I have this code on my M2 MacBook Pro, running macOS Sonoma 14.1.2:

let host = rodio::cpal::default_host();
let devices = host.output_devices()?;
for device in devices {
    let name = device.name()?;
    println!("{name}");
}

However, it does not output "MacBook Pro Speakers", which are listed with the .devices() call as well as in System Settings.

It lists only Steam Streaming Microphone, Steam Streaming Speakers, and "(name)'s Headphones".

I'm having the same issue on a macbook pro with an M1 pro chip.
I noticed that if macbook speakers are chosen as an output device in the system, then they show up as normally, but when something else is set then cpal fails to list them as an output device.

Please let me know if there are any updates on this issue.

@randomairborne did you manage to use macbook pro speakers?

[randomairborne]

No, I didn't. It's generally best not to comment on an issue without something to add, though.

I have the same issue, but I should note that if I call supported_output_configs on the output devices that don't show up in output_devices() but do show up in devices(), it fails with a BackendSpecificError with a description that states "Invalid property value"

I have the same issue on a macbook pro with m1 max chip, including the exact behaviour described by @LevonAsatryan above.

check this #894

@louis030195 I don't immediately see how this is related, could you explain?

Another detail: I observe the issue on MacOS 14.5, but it works fine on 15.2. Perhaps something changed in the CoreAudio API?
