## Use fakeAudioOutputStream

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using audio

// Play and control audio through Yeho's bounded audio runtime.
fakeAudioOutputStream sample = fakeAudioOutputStream(1, 1)
Console.Log(Text.From(sample.state))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.audio__fakeaudiooutputstream"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"
