here's a small script to inform you about the volume #!
what is the command to increase/decrease volume on hdmi
amixer set master 5+ and amixer set master 5-
have no effect on it
using xfce 4.10
As mentioned in the title, amixer appears to mute all audio channels but doesn't unmute them when run again. As a result, the media key I'd like to serve as mute/unmute only works to mute, and I need to go into alsamixer manually to unmute them.If I understood correctly, amixer sset Master toggle would only affect the master channel, when that obviously isn't what is happening.
I want to set via my Media Keys, so I first have to find out the terminal-command.
Outputs are:
amixer set Master 10%- amixer: Unable to find simple control 'Master',0
amixer scontrols Simple mixer control 'IEC958',0
amixer set 'IEC958' 50%- amixer: Invalid command!
How can i fix that?
Sometimes I'll be listening to a song at 100% volume, and it is not as loud as I would like it to be. I can run pavucontrol and pull the slider to make the output above 100%, but I prefer the command line and am looking for a way to do this from there.
On my HP computer running Ubuntu 12.04, the brightness and volume increments were much higher than I wanted. On top of that, the notification for the volume was just plain wrong (0% sound did not correspond to 0 on the progress bar). So I decided to override these options with my own commands.
Looking at the amixer man page, the mapping mentioned earlier can be invoked in amixer with the -M flag. So using amixer -M [...] works in the units that you see in alsamixer. These are "more natural for human ear".
Hello, all. I have recently ordered a ThinkPad, and I love it. Recently my volume keys (only up/down, not mute) decided not to work. I have been unable to identity any changes in my setup that would account for such behavior. I finally restored the main functionality of my media buttons by mapping those keys to the command 'amixer set Master 5%+-' with ccsm.
How can I set the volume keys and sound indicator to change only the master volume?
Now when i change the volume from 0 to 100%, using the keyboard or the sound indicator, first I change the PCM level (master remains at ~0%) and then the master level (PCM remains at ~80%) and then the PCM level again for a bit, resulting in a non linear volume increase.
The issue apeared when I first installed Ubu
