Hi all - Happy Holidays!

Hoping someone can help me out with something pretty small but I can't seem to figure out. I tried searching for this topic but I may be using the wrong key words.

Recently whenever I open the YouTubeTv app on my roku there will be some type of music that plays when it opens. Similar to how Netflix has that "duh duh" (hope that was close to what it sounds like phonically ha) when a movie/show starts.

How do I mute this sound? Is it even possible? It's fairly loud compared to how regular streaming volume is. Sometimes our son will wakeup when the sound suddenly comes on.

We have an LG using the Roku device to stream YouTubeTv and Netflix if that helps.

Any help would be honestly greatly appreciated.

Thank you & stay safe! :-)
