I understand the ALSA is the underlying mechanism with PulseAudio on top of that. I am using Xfce 4.12 on Debian 10 and have access to PAsystray and the volume control that it brings up.
On that screen are horizontal sections representing the various streams.
The first question is why there are multiple streams with the same name?
The second question is why do they not go away when finished? Can they be removed?
The third question is that system sounds are very loud, but that control does not lower their volume. Where is the control for system sounds?
Thanks.
