Hi,
I'm trying to use an old set of Logitech earphones on my Fedora 23 system. I use mplayer to play videos WITH audio tracks. This used to work with Fedora 22 and earlier but now the earphones don't work. I use /usr/bin/gnome-control-center to adjust settings and to a minimal test from various sources. All devices tested produce sound. I'm missing something here but can't seem to figure out just what that is.
Can I get someone to give me some hints/clues/tips/suggestions please?
Regards,
George...

Could be that mplayer's own volume controls are turned down. In the command line, I think it's the - and = hotkeys to go down/up (check the man file).
With pulse-audio, there also seems to be a per-application storage of volume controls. So if you turn the volume down too far while playing something, it stays that way the next time you run that same application.
There's also the problem of some dopey things that as soon as the volume control goes very low, they also mute the channel. But they don't un-mute the channel if you try turning the volume up again.
So, look at the hardware mixer. e.g. Run "alsamixer" in the command line, cursor left and right to check all sources that may be off the edge of the screen, un-mute and raise volumes.
Do the same with pulseaudio (with my old Gnome/Mate desktops, right click the audio volume icon, and bring up the preferences). You can select where the sound goes out (if you have more than one device), and the applications tab lets you control volume levels from individual applications. Start mplayer playing a long file, and delve through the level settings.
