Static electricity sound on 3/4 channels, MacOS

[olegus199]

Hello! I would like to express my gratitude for this awesome crate. It's the best game sound framework for now. For me, as a musician, it's very comfortable to work with. But, unfortunately, there's a bug while audio is playing.

As you can see on the screenshot that I've attached: there is insane clipping on the PH 3/4 channels. All the audio from the computer goes to the AN1/2 and on the PH 3/4 there is a wild electricity sound with +24 dB clipping. I've noticed it in my own project (a game made with Bevy engine) and decided to create completely new clean project "Hello world" using Kira audio only. And the bug is there too.

Besides the screenshot I'm attaching an audio with that sound, which I've recorded (DON'T PLAY IT LOUDLY):

I get the same sound regardless of different songs that I have played. The sound wave looks like this:

After that I've created Cpal basic project (from Cpal's examples folder) to see if the bug came from there. And it turned out, that there is a sound on the 3/4 channel, but it is merely a copy of original sound from the 1/2 channel.

I'll appreciate if you can do anything with it, thanks!

Hi @olegus199, can you try the zero-out-additional-channels branch and see if the problem persists?
