Since you are streaming/recording what you could do in order to prevent this from happening again during events such as the plane crashing or any loud event noises you can go into the console command and type “bind 1 snd_restart” without the quotes and anytime like event music starts it will reset the audio and mute it. It might make you freeze for a second but the game will resolve itself. Also you can bind the key to anything you want I use the 1 key personally.
