4 years ago That's really odd, but I can't reproduce it as I don't have access to a Mac at the moment. It might be an issue with the types being generated by bindgen. If you have time, it would help a lot if you posted the results you get from running this code:
use miniaudio::{Context, Device, DeviceInfo, DeviceType};
pub fn main() {
println!("sizeof(device) = {} bytes", std::mem::size_of::<Device>());
println!(
"sizeof(device_info) = {} bytes",
std::mem::size_of::<DeviceInfo>()
);
println!("sizeof(context) = {} bytes", std::mem::size_of::<Context>());
let context = Context::alloc(None, None).expect("failed to create context");
println!("Devices:");
context
.enumerate_devices(|_, device_type, device_info| {
let device_type_str = match device_type {
DeviceType::Playback => "Playback",
DeviceType::Capture => "Capture",
DeviceType::Duplex => "Duplex",
DeviceType::Loopback => "Loopback",
};
println!("\t[{}] {}", device_type_str, device_info.name());
print_device_info_bytes(device_info);
true
})
.expect("failed to enumerate devices");
}
fn print_device_info_bytes(device_info: &DeviceInfo) {
let size = std::mem::size_of::<DeviceInfo>();
let ptr = device_info as *const DeviceInfo as *const u8;
unsafe {
let mut row = 0;
let slice = std::slice::from_raw_parts(ptr, size);
println!("Device Info Bytes:");
for byte in slice.iter() {
print!("{:02X} ", *byte);
row += 1;
if row >= 32 {
row = 0;
println!();
}
}
println!("\n");
}
}Just so I can get an idea of what types are being generated and where the 0's are coming from.

Hi, apologies in advance if I am using the library wrong, I am a beginner Rustian.
I am using your device detection example code on a Mac and also wanted to check for the channels, samplerate and formats, like this:
However I get this output, where max channels, samplerate and formatting all seem empty. However there do seem to be 6 supported empty formats...:
