Volume adjustment step.

[zloe]

Hello!
I google it for two days and finally gave up.
How to change volume adjustment step for volume keys?
I set up custom shortcuts (e.g. pactl set-sink-volume 1 +1%) but it really ugly workaround.
Is any way to change step in built-in functions?

Why would you need that ? Just curious.

To my knowledge there is no adjustment configurable.

You could try amixer:
http://www.commandlinefu.com/commands/using/amixer
Can increment in db or integer (HW value, I think, typically 0 to 31), and percent (maybe?).

I have these hooked up my numberpad +/- keys:

Code: Select all

amixer sset Master,0 1+
amixer sset Master,0 1- 

Edit: You can find the limits of the integer value like this:
amixer get Master

Code: Select all

Simple mixer control 'Master',0
  Capabilities: pvolume pswitch pswitch-joined
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 31
  Mono:
  Front Left: Playback 31 [100%] [0.00dB] [on]
  Front Right: Playback 31 [100%] [0.00dB] [on]

So the lowest increment is "1", which is about 3% or 1.5db:

Code: Select all

  Front Left: Playback 30 [97%] [-1.50dB] [on]
  Front Right: Playback 30 [97%] [-1.50dB] [on]

5% is too much for my speakers. 1% is just fine

How specifically did you 'hook them up'? Script, assign keyboard shortcut somewhere, etc.?

My goal is to get finer volume control in "audtty" (an ncurses command line controller for audacious music player) as well as from mousewheel on volume icons in gui.

I found a solution using dconf

Code: Select all

env | grep DESKTOP_SESSION=     #gives cinnamon,mate, etc
dconf read /org/cinnamon/settings-daemon/plugins/media-keys/volume-step #6 by default
dconf write /org/cinnamon/settings-daemon/plugins/media-keys/volume-step 2  #set the step to 2 or 3

Alternatively use dconf with the dconf-editor GUI

So i've just recently installed Mint 19.2 Cinnamon for the first time (first time Linux user in fact!) and as I use an Audioquest Dragonfly as my audio DAC, I immediately was annoyed as well by the 5% volume step. I would much rather have 1%. I tried the steps above, mainly using the custom keyboard shortcuts, but they weren't working. Discovered upon further investigation that the commands mentioned appear to now be out of date. The process to now follow is:

System Settings > Keyboard > Shortcuts > Sound and Media > On Volume Down & Up, double click the assigned keyboard bindings and press backspace for each > Custom Shortcuts > Add Custom Shortcut >
Name: Volume Up, Command: pactl set-sink-volume @DEFAULT_SINK@ +1% and for Volume Down, pactl set-sink-volume @DEFAULT_SINK@ -1%

Now as previously mentioned, this does remove the on-screen overlay, but at least my headphone listening experience has improved!
