Audio AudioClip plays at 100% volume, even without AudioListener

I have 2 problems that exist even if I start a new project in an old Unity version. No scripting, just having an object with AudioSource in the scene that is looped with an AudioClip on it.

First:When there is no AudioListener, the sound will be played anyway
Second: When the object is 600 units away from the AudioListener, the sound is still 100% volume.

It looks as if the sound was just played raw. There is no consideration whatsoever concerning AudioListeners/-sources. Also, not using mixers.

Using Unity 2018.3.3f1 (is this 2019.1 ? Cause I found that this bug was fixed in 2019.1 which doesnt seem to exist)

 

help please what am I doing wrong here?

 

did you set Spatial Blend to 3D?

 

Uhm... Okay?! Now this had an effect.
Wow, thanks a lot, I would never have found this. Can you tell me why I need to set it to 3D when I have a 2D game?

 

Hmm that didnt really help my understanding. So 2D means the sound will always be played, no matter the distance? What does "original channel mapping" mean here?

 

It means the audio track's left channel will come out of the left speaker and the right channel from the right speaker.

2D in this context is more like "just play this audio as is". (without caring where the audio source is)
