Hello! I’ve been switching to fmod in our project and it works fine but in webgl a very bad sound cracking/poping effect is heard. I’ve tried setting the quality of audio compression to 100% but it doesn’t improve. using Unity 2022.2.11 using Fmod 2.02.11 What could be the cause? > **[demo-audio](https://www.whyp.it/tracks/84357/demo-audio?token=ZI3fr)** > > Listen to this track for free on Whyp. ---

Hi, This may be related to an issue here: [Net Stream hiccups at a regular rate](https://qa.fmod.com/t/net-stream-hiccups-at-a-regular-rate/19783), which was resolved in our 2.02.13 update. Could you try updating your integration and lt me know if that helps! ---

I updated and rebuilt and It doesn’t resolve the issue. A bit more digging revealed its only happening in my computer so far and only in chromium browsers (Opera, Edge, Chrome). Even the [Unity WebGL Player | Unity HTML Demo](https://fmod.com/assets/html5/js_unity/demo.html) example has the same issue with distortion and crackling. I can provide more info if necessary to be able to dig up the issue ---

Hi, Thank you for sharing that information, I will link to another issue that might have a solution to the problem here: [Audio cracking on web depending on server? - #2 by jeff\_fmod](https://qa.fmod.com/t/audio-cracking-on-web-depending-on-server/19520/2). In the meantime, any other information you are able to provide would be useful. ---

Tried in different servers and performance settings and the issue persists. I think now I have narrowed the issue even more, it only happens when using any headphone jack in the computer. I assume its a driver/hardware problem in conjunction with something that Fmod and chromium are doing together. At this point I consider the issue so specific and narrow that I don’t think its worth it to invest more time on it. Thank you for the help. ---

As the issue for me it was related to the audio jack I just stop using it
