Increase volume control steps on volume wheel

[SiO2*]

Hello,
I'm running Ubuntu 12.04.1 64bit, what i'd like to do is increase the number of steps between mute and 100% while using my volume wheel. Right now it seems like there are 5 steps, which is about a 20% change for just a small amount of rotation. It'd be nice to have the volume up and down 'shortcut' to be more in the range of a 3-4% change.

I'd imagine this is hidden in a config file somewhere, but i'm not sure where to look.

I've already searched this forum but I've found only solutions valid for Ubuntu 8.10 or older that don't work on Ubuntu 12.04 (e.g. dconf editor or gconf editor)

Thank you in advance for your help!

on my 10.04 install the setting is in the configuration editor (gconf-editor) under
/apps/gnome_settings_daemon/volume_step
the actual file is here
~/.gconf/apps/gnome_settings_daemon/%gconf.xml

<?xml version="1.0"?>
<gconf>
    <entry name="volume_step" mtime="1311896260" type="int" value="2"/>
</gconf>

you could use a script to do this if that setting no longer exist

Thank you for your reply.
This setting no longer exists in ubuntu 12.04, I've tried to create the file xml with the exact path and content you posted but it doesn't work...
I'm sorry but my scripting skill is close to zero, I kindly need some more detail on what the script you suggested should do

[pqwoerituytrueiwoq]

to install the script
gksu gedit /usr/local/bin/volume
paste the code in the last post
looks at lines 2 to 4
lines that start with a # are comments (anything after a # is a comment)
line 2 has automatic detection disabled via the # character
line 3 is line 2 in manual (delete this line for auto to work)
line 4 is the volume step (increase/decrease the number as needed)
save it
close gedit
sudo chmod +x /usr/local/bin/volume

now the script is installed, now you just go into your keyboard shortcuts and create a new keyboard shirtcut for the volume
the commands would be
volume plus
volume minus
run volume in a termianl for more commands


BTW if the command in the 1st post adjust your sound you don't need the script you can just add those command to keyboard shortcuts

Very clear thank you.
I followed your instructions for the script but this is what I get after running "volume plus" in a terminal:

silvio@Qosmio-G50:~$ volume plus
Waiting on volume to become setable (infinite loop on invalid sink name)
Waiting on volume to become setable (infinite loop on invalid sink name)
Waiting on volume to become setable (infinite loop on invalid sink name)
Waiting on volume to become setable (infinite loop on invalid sink name)
Waiting on volume to become setable (infinite loop on invalid sink name)

Waiting on volume to become setable (infinite loop on invalid sink name)
Waiting on volume to become setable (infinite loop on invalid sink name)
Waiting on volume to become setable (infinite loop on invalid sink name)
^C

setting up the shortcuts, the script "volume" launches several instances of itself and the system get stuck...
any idea about the reason?

volume dump;cat /usr/local/bin/volume | head -4

Thanks again.
Same behavior:

silvio@Qosmio-G50:~$ volume dump;cat /usr/local/bin/volume | head -4
alsa_output.pci-0000_00_1b.0.analog-stereo
#!/bin/bash
# SINK_NAME="`pacmd dump | grep set-sink-volume | sed 's/ /\n/g' | grep alsa | head -1`" # this is auto detect but it may break using the reset action to fix maxed volume at login
SINK_NAME="alsa_output.pci-0000_01_00.1.hdmi-stereo-extra1"
VOL_STEP="0x01000"
silvio@Qosmio-G50:~$ volume plus
Waiting on volume to become setable (infinite loop on invalid sink name)
Waiting on volume to become setable (infinite loop on invalid sink name)
Waiting on volume to become setable (infinite loop on invalid sink name)

Waiting on volume to become setable (infinite loop on invalid sink name)

please paste the command i gave you
why: i said volume dump not volume plus

Problem:
You are using the sink name for my hdmi card not your analog one
this will make it use your analog sound card

sudo sed -i '/s/alsa_output.pci-0000_01_00.1.hdmi-stereo-extra1/alsa_output.pci-0000_00_1b.0.analog-stereo/' /usr/local/bin/volume

you could do this

volume plus alsa_output.pci-0000_00_1b.0.analog-stereo

or (since you only have 1 sound card with alsa in the name)

volume plus `volume dump`

sorry the output is in italian but,
riga 2, riga 3 etc. mean line 2, line 3 etc.
"File o directory non esistente" means "File or directory doesn't exist"
riga 98: errore di sintassi vicino al token non atteso "newline" means

Thank you for your patience
