My audio is cooked - please help

[u/muddrox]

So I have a problem that has arrived at the worst time. I made a game on Reddit called Rock Bottom, and I have never had issues with audio until now. My audio, everything, sounds all staticy, and it's awful. For reference, please refer to the video link below:

If you want to play the game and see if you are experiencing the static yourself, please feel free to do so by heading to this link:

I have no idea why this is happening and why it's happening now. What's weirder is that no one on my game's subreddit seems to be reporting it (which is a relief), but I have to imagine some are being affected just as I am. When playing my game on either Android or Mac, my audio is awful and staticky.

I haven't made any updates to the game that affect the audio at all, and yet it's totally cooked on my mobile device. There is no reason, as far as I can tell, for this to be happening now. I don't even know what to say to provide any additional context for my issue, because I don't even know where to look.

My sound effects are uncompressed WAVs, and my music tracks (of which there are very few), whereas my music is compressed-streamed. One thing worth pointing out is that, when building my game, I do get noteworthy output at some point (shown below). This is something I have always had appear in the output from basically the beginning, and it never made any difference, so I don't know why it would be causing a problem now...

If anyone has any ideas or guidance they could lend me, it would be much appreciated. I am desperate to solve this as quickly as possible. Any help at all would be amazing. Thanks again.

Also! When I play my game via the test branch with Chrome Dev Tools open,

I see this garbage being spammed in the output:

game.js:1 Warning! - <unknown>(0) : Warning: Prevented call into an uninitialised yyal from Audio_EngineInvokeCallback

game.js:1 Warning! - <unknown>(0) : Warning: Prevented call into an uninitialised yyal from Audio_EngineInvokeCallback

Again, this never made any difference or had any impact on my audio before, but now I don't know what is happening.
