I have the problem, that I cannot change the volume when I'm in a call. The Onscreen-Display is shown when pressing volume up/down but the volume stays the same. This happens on a normal call and also with loudspeaker on.
Volume control in other applications, for example with music-app, works like expected.
Is there someone with the same issue?
PS: This happens to me on Volla22 with 24.04-1.0 stable
