I am having trouble after the audio imports with the type of codec that is given for the audio asset. The asset is being treated like a sprite instead of an audio file showing the audio waveforms. I do not have this trouble when it comes to the Mac, Windows, and Linux build, but am having this trouble in 2022.2 and .3 LTS and the 2023 version of Unity. 
What type of audio file is it?
Both mp3 and wav files I am having trouble with.
For WebGL, the audio importer leverages system libraries to convert to aac/mp4. In the case of Linux, it looks for avconv and fallbacks to ffmpeg if necessary. I recommend you check the availability of these and update them if possible.
Please share the version of these after & before updating, and let me know if it changed something!
Cheers
Thank you
