With rooted phones I used Viper4Android to boost audio volume and tweak some other details. I'm not audio obsessed, but often, the volume level is low for activity outside or where there's some ambient noise. With wired earphones, it's less of a problem, but with Bluetooth, it's more of an issue. I recently got a Pixel 7 and have installed GrapheneOS. I can use my wired earphones with an adapter, which seems like it'll be OK. But if I want to use my Airpod Pro's, it would be nice to get that audio boost. Any thoughts on what you all are doing to enhance audio?
