latest commit (2023/12/01) introduces a regression in PPP

b4924e11 introduces a bug that significantly impacts usability.

With this commit, the speaker volume now changes on its own very frequently. Whenever the volume changes, there is an on-screen notification to indicate the current volume level that prevents interacting with anything (except the notification and on-screen keyboard). The notification only lasts 1 second, but with the volume constantly changing, it is on the screen most of the time.

Upon downgrading to 4ada441b the issue disappears (the volume no longer changes on its own and the notification only appears when manually changing the volume).
