Linux Spotify Ad Mute

_README.md

This script only works for older versions of Spotify for Linux.

An actively developed admute script for Spotify on Linux can be found here: https://github.com/SecUpwN/Spotify-AdKiller

spotify-admute.sh

#!/bin/bash

#Linux Spotify Ad Mute v2
#Put this script in the directory the "spotify" binary is in (e.g. /usr/share/spotify).
#To open Spotify, run it instead of the "spotify" binary.
#System sound will be muted as soon as an ad plays
#Find updated versions at: http://pcworldsoftware.kilu.net/files/link_spotify-admute.php and/or https://gist.github.com/pcworld
#On Debian, you need the package "pulseaudio-utils" for the command line util "pactl" which used in this script
#
#Update: For newer 0.8.x versions (x>4; such as 0.8.8), use this script: https://gist.github.com/pcworld/3198763/#comment-813440
#For 0.9.x: https://gist.github.com/pcworld/3198763/#comment-857143

Hey guys, thanks for the useful script. As per good open source tradition, I've improved the script and pasting here.

Improvements

• Automatically attaches to Spotify when the player is open. So now you can run this script on system startup and once Spotify is open it attaches to it. When close - detaches. When restarted - attaches to new instance!
• Pause when unmuting (configurable, default = 2 sec)
• New logging (with time, not that verbose)
• Code refactored a little bit

Bugfixes

• Mute didn't work after spotify restart (there were two Spotify sinks)
• When the script was crashed / killed and Spotify was muted, it didn't unmute the Spotify

#!/bin/bash
# Based on https://gist.github.com/pcworld/3198763
# Mute spotify when it starts advertisement
# Run like this
# nohup bash ~/bin/spotify/mute.sh  > /tmp/spotify_mute.log &

I've put this to my space too - https://gist.github.com/logical-and/825bab160d604d82bf6ad9ebd3a6410d. Will update there when needed (bugfixes, incompatibilities with Spotify updates)
