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

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)
