TypeError: arraySequence[0] is undefined

Hi @slow_izzm, thanks for replying.
I didn’t post the code because it’s too long and I wouldn’t know which part is relevant to be honest. I’ve extracted the code relative to the audio part (here) and it works fine, no errors in the console. However, the only arraySequence[0] available in my scripts is in the ps5-sound library, I think it relates to the buffer (here). So it should be that, crashing with some other thing in the code, no idea what.
The app works just fine a part from this error in the console which exists only in Firefox.
I was just wondering if anyone encountered a similar problem or had a hint to what I could look at to start debugging. It’s more about curiosity at this point.

cheers
