Based on the search results, here's what I found about `ma_sound_at_end()` in miniaudio:

## Documentation Overview

`ma_sound_at_end()` is used to check if a sound is at the end. This is part of miniaudio's high-level API for sound management.

### Basic Usage

You need to periodically call `ma_sound_at_end()` to know when the sound has finished.(no content)You won't be able to use `ma_engine_play_sound()` for that because it doesn't give you a `ma_sound` object. Instead you'll need to initialize a sound `ma_sound` object with `ma_sound_init_from_file()`.

### Example Pattern

A common pattern from the documentation shows polling for sound completion:

```c
ma_sound_start(&sound);
while (ma_sound_at_end(&sound) == 0) {
    // Wait for sound to finish
}
ma_sound_stop(&sound);
```

### Alternative: End Callbacks

To set the callback you can use `ma_sound_set_end_callback()`.(no content)Miniaudio added support for callback notifications when a sound reaches the end.

# ma_sound_at_end() Behavior

Based on the GitHub discussion, `ma_sound_at_end()` is used to check when a sound has finished playing. The maintainer explains:

> "you need to periodically call `ma_sound_at_end()` to know when the sound has finished"

The user's implementation shows it returns 0 while playing and a non-zero value when finished:

```c
while (ma_sound_at_end(&sound) == 0)
{
}
```

However, the provided discussion doesn't specify:

- Whether the function maintains a true state after completion
- What happens after seeking or restarting playback

The maintainer recommends using the low-level API instead and consulting the official documentation at miniaud.io/docs/manual for detailed behavior specifications, suggesting that `ma_sound_at_end()` is part of the higher-level API that may not be ideal for music player applications.

# ma_sound Seeking and End State Documentation

Based on the miniaudio documentation provided, here's what you need to know:

## ma_sound_at_end()

The documentation states: **"Use ma_sound_at_end() to determine whether or not a sound is currently at the end. For a looping sound this should never return true."**

## Seeking and Restarting

When you seek a sound back to the beginning using `ma_sound_seek_to_pcm_frame(&sound, 0)`, the documentation indicates that **"When a sound is stopped, it is not rewound to the start."** This explicitly shows that seeking is the mechanism for returning to the beginning.

## Does ma_sound_at_end Reset?

The documentation does **not explicitly state** whether `ma_sound_at_end()` automatically resets after seeking. However, logically, if you seek to frame 0 (the start), the sound is no longer at the end of the file, so the function should return false. The documentation emphasizes that seeking is the proper way to rewind, implying that the end-of-file state should change accordingly when the playback position moves away from the end.

For definitive behavior regarding state changes after seeking, you would need to consult the actual implementation or test the behavior directly.

Composition yields capabilities beyond any single agent.

  1036→## Random Module
  1037→
  1038→The `random` class is a child object that provides seeded random number generation.
  1039→
  1040→### Design Decisions
  1041→
  1042→1. **Child object pattern** — Random is added to objects and dies with parent
  1043→2. **Wraps C functions** — All randomness comes from C engine's RNG
  1044→3. **Default on `an`** — A global random is created on `an` for convenience
  1045→4. **Seeded for replays** — Seed can be stored and restored for deterministic replays
