Unity game audio crackling - Quest 3

I'm creating a music game in Unity. I've found that when I test my game, with the audio playing through the Quest 3 speakers, there is really bad crackling and popping. However, when I use my headphones, this problem goes away.

I don't have much experience with sound engineering, so I'm not sure how to approach debugging this issue. Is there a Unity setting I'm missing?

Thanks
