did you change the audio source type to 'static'? If yes then i think it's just because the audio file you're trying to use are too big.
My audio file is just about a dozen seconds long so my web build ran smoothly.
Yeah, I figured out that I had to use static, but once I started using static the sound effects cut out eventually and never come back...
Yeah I get that sometimes when I try to port my game to web, the engine doesn't support browser so much. My best suggestion is to cut a part of your audio off or reduce the audio quality down.
