Audio channels are sometimes reversed

Bevy version

main, 0.8.1

Relevant system information

macOS 12.6
Macbook Pro (M1 Max)

What you did

Modified the audio example to play this sound:

RL.zip

cargo run --example audio --release

What went wrong

This audio file consists of some tones alternating from right->left->right->left.

However, when played with bevy, I hear left->right->left->right

This behavior is not consistent. Without --release, the audio plays in the correct channels.

It seems likely that this is an issue upstream with rodio or cpal.

I found the same behavior in a rodio example (also tested a wav rather than an ogg). RustAudio/rodio#444

But a quick and dirty attempt in cpal didn't produce the same behavior.

Interesting: this was discovered in #6028. Apparently it's a pre-existing issue.
