Command to change volume to specific value in Linux

Command to change volume to specific value in Linux


I would like to create a shell script to set the Spotify internal volume setting to a specific value, how is it possible? I have seen it on Mac but not on linux...


Thanks in advance

It is not possible yet. Volume is a property that you can change in the MPRIS D-Bus interface so it would be ideal for setting the Spotify volume in a shell script.


However, the Spotify client has not implemented that yet.

Thank you for your answer, yes I have played around with Dbus but the Volume property gives me an error every time when calling: (e.g 0.2 as value) 




org.freedesktop.DBus.Error.InvalidArgs: Error setting property 'Volume': Expected type 'd' but got 's'


What data type should be in the argument..? 



That looks more like the dbus library in perl/php/whateverlanguage you are using has a bug. It sends something as a string 's' when it should send it as a double 'd', even though it looks like you are giving it something that would be a float/double in many languages. But it doesn't really matter if you fix that.


This will correctly send the the MPRIS D-bus Volume property change to Spotify, but Spotify will just ignore it.


dbus-send --print-reply --session --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.freedesktop.DBus.Properties.Set string:org.mpris.MediaPlayer2.Player string:Volume variant:double:0.2


Still not working as of today 😕
