wav file not playing outside of game environment

[rohrlich]

I want to play a wav file outside of the game environment. There are no errors but I don't here the sound unless I call ebiten.RunGame(). So what needs to be setup to get this to work. Is the key in the UIContext code?

[hajimehoshi]

This is intended and there is no way to play audio before RunGame so far. If you just want to play an audio, use github.com/hajimehoshi/oto directly, but in this case you cannot use Ebiten.

Thank you for the quick reply!

[rohrlich]

Though I can run the oto code, I haven't found a way to get a wav file stream to pass to NewPlayer. Is there a decode method that will return a Reader I can pass to NewPlayer or other solution?

[hajimehoshi]

Have you tried https://pkg.go.dev/github.com/hajimehoshi/ebiten/v2/audio/wav#DecodeWithSampleRate?

[rohrlich]

Yes that is exactly what I tried, should have mentioned that. I get linker errors, presumably because the audio/wav import is including the oto which I am also importing. Here are the first couple of errors:

[hajimehoshi]

Which version of Ebiten are you using?

[rohrlich]

V2

[hajimehoshi]

v2.1.4, or the latest commit?

The error message seems to mix oto v1 and oto v2.

[rohrlich]

From my go.mod:
github.com/hajimehoshi/ebiten/v2 v2.1.4
github.com/hajimehoshi/oto/v2 v2.0.0-alpha.2

[hajimehoshi]

OK so ebiten v2.1.4 uses oto v1, while you use oto v2. Please try to use oto v1.

[rohrlich]

ok, I'll try that. Thanks!

Working, thank you so much!
