Please get this sorted out. We have been loyal sonos customers for ten years or so and add a new speaker annually. You must be able to keep youtube playing at the same level by now. I have faith that your brilliant techs can do it. Give it to us please!  Some videos/ audio plays at a mumble then the next blasts on at stadium concert level. Please keep them at the same volume we set our speakers. I know you can do it   This is ridiculously annoying. Thank you for your help
