Hi I keep getting strange sound interruptions (for want of a better word) here and there.. reminds me of really old movies if you know what I mean Here is a sample recording <https://drive.google.com/file/d/1XOIsofU2nD5vfZC8F7khGeIXV4KVIDBI/view?usp=sharing> (just audio, there is no video) You can clearly hear it at ~ 00:30+ seconds and there are other instances throughout the recording I'm using freeswitch as a part of bigbluebutton project. It's not that noticeable when your conversation is short however if you listen to a lecture it gets annoying. I tried using different webcams, different PC\laptops, but it's all the same. It was tested with both energy level=100 and energy level=0 Could anyone help troubleshooting it? What should I try changing? Thank you
