When streaming video or sound from any website i.e. YouTube, Netflix etc. my audio changes level automatically. I will start a video, the audio level will be set and when I pause and resume playing, especially multiple times in a row, the audio level will increase by itself every time i resume playing however not by increasing either the YouTube/streaming site's volume setting nor my Windows volume slider. If an episode on Netflix finishes and the next episode starts automatically, the volume will be much lower once playback resumes but again, no volume settings/sliders have changed. If I pause and play again, the volume goes up and if i pause and play multiple times it will gradually go back to the original level. I have removed application control of volume in Windows from Firefox and have tried searching for this issue but have yet to find a solution. Chrome does not have this issues on my same device. On rare occasions, the audio will automatically boost all the way up to maximum level and become distorted regardless of which audio device I'm using i.e. wireless headphones, external sound card, any other audio device. I then need to pause and un-pause a few times before it goes back to normal Please help!
