In the above picture (it’s in Italian but it should be understandable), you can see in the left the global system audio output level, in the middle the global audio input level (i.e. record), and in the right the audio level of an application (it’s qmmp in this case, but this also applies with everything else)
When I adjust the global volume by raising or lowering the leftmost bar, the application volume also goes up (or down); the same is true when I want to adjust the volume for a single application if I raise it, the system global level also goes up, and so on.
This behaviour is rather strange (it is the first time that I experience this, in any OS, Linux or not) and also a bit annoying: I want to be able to adjust the volume of a song or movie that is being reproduced, without affecting the system sounds (alerts, notifications, and so on).
I’d like to have every bar independent from other ones, how can I do this?
If I understand you correctly, this can be achieved by configuring flat-volumes in PulseAudio (/etc/pulse/daemon.conf). I can’t remember if enabling or disabling ‘flat-volumes’ is required.
I don’t understand. I’m the only user of this PC and I have set up only a single user account. What I mean is that changing the volume level inside an application also changed the system volume level.
Anyway, I did as suggested, and by setting flat-volumes = no in */etc/pulse/daemon.conf *it now behaves as I expect. I just don’t understand why this is not the default settings, but I can consider this issue solved now.
Bit when you say “system level”, then that is something that is set for all users. That is regardless of the fact that there is only one user on that system that regularly logs in in the GUI. Linux is a multi-user system. And when you prefer to ignore that, you will have problems understanding things now and then. You will even have problems to convince us and yourself that something is set system wide when you did not test that with another user
BTW, that setting is in /etc, thus it is system wide and will also influence otrher users. If you care or not.
[HR][/HR]Yes, I know that the system is configured to have many system user accounts, what I wanted to tell is that I’ve only set up a single user user account; I’m sorry for the puns, I hope that it is clear
Anyway, what I wanted to tell is that the audio settings inside a specific application were also affecting audio levels outside it; but it is solved now.
