Duplicate Master volume control in alsamixer
I have a Creative X-Fi soundcard and alsa and pulseaudio. In alsamixer, there are three 'soundcards':
1. Pulseaudio with just one controller: Master.
2. Creative X-Fi with a bunch of controllers, including Master.
3. A HDMI device, which I never use.
The issue is with the duplicate Master volume controls. They are not in sync. When I adjust the volume in some application like mplayer or moc, one of the two Master volume controls is used. The selection doesn't appear to be determistic, but random. The annoyance comes, when I want to control the volume from different applications.
Consider this scenario: I'm listening to some music with moc and adjust the volume to 30%. Later I want to watch a movie with mplayer and want to bring the volume back up to 100%. But I can't with mplayer, because the Master volume control mplayer has chosen is already at 100%. I have to go to alsamixer to learn which one of the two Master volume controls is at 30% and bring it up to 100%.
Now I don't really have a use for two different Master volume controls. I would like to get rid of one, preferably the pulseaudio one. If I could force the two to be in sync, I guess I could live with that too.

Re: Duplicate Master volume control in alsamixer
You shouldn't adjust any of the ALSA mixers if you use pulseaudio, precisely due to this reason. If you control all your volumes from within pulseaudio (with e.g. pavucontrol) those values will be correct, and remembered across the board. You can simply keep your master at 100% adjust the volume of only cmus to 30% and mplayer will be able to use 100%. If the application in question lacks direct pulseaudio support it's advisable to do the volume control from pavucontrol instead of the native capabilities.
Another thing to verify, which card is mplayer/moc is controlling? If you must do your controlling from within mplayer itself (as opposed to what I'd recommend above) make sure that it controls the pulse master, can you post
aplay -lL
#While having the programs you want open
sudo fuser -v /dev/snd/*
pacmd list-sink-inputs
#output of mplayer/mocLast edited by V1del (2017-06-01 08:57:09)

Re: Duplicate Master volume control in alsamixer
That sounds like using pulseaudio is optional. I don't recall why I did install pulseaudio and since I don't think I need it maybe uninstalling (or disabling) pulseaudio would be the easiest solution. Or is there something I should be concerned of?
Anyway, this is the output of aplay -lL:
