There’s a health related problem with Gnome’s sound settings that needs to be corrected.
Volume can suddenly go up when using different applications for hearing videos or music. I’m always very careful when using headphones because I already have hearing problems. It happened to me and it was very painful and a couple of days after my ears still hurt.
I tried fixing this by manipulating the volume mixer but it really behaves in unexpected ways so it is not clear how should the user set the volume because sometimes sound is up for one application and down for another and the volume manager should prevent this from happening.
Anyway, have tried managing volume controls but there’s always seem to be a problem where it’s impossible to set the precise overall volume output and prevent sudden volume changes. If the volume manager is not clear for the user and it also behaves unexpectedly then it is definitely a software problem.
Programmers and designers should be very careful when developing applications that could hurt users and I think that there are no safety guidelines being followed or enough testing to prevent this from happening.
I know that sometimes software is provided “as is” but for some pieces of basic software there should definitely be a project’s a responsibility for users safety. At least in something very basic and widely used as volume controls.
