Hello!
I have been a long time user of GrapheneOS, ever since the Pixel 4A was new. I have mostly the same apps as always, but with this phone I am seeing that my volume will adjust itself back to the middle if any video or app is playing something (DuoLingo, YouTube, Jellyfin, SimpleGallery). This is at best very jarring, and at worst incredibly disruptive.
What can I do to even check what might be adjusting my volume...? Not that I can really blame any app in specific. Maybe I could call out the DexcomG6 app, but that would be because it's genuinely terribly in the first place. :)
