Extension freezes when playing sound

[sainoba]

Whenever I try to play a sound the extensions seems to get stuck.
It just keeps displaying Running on save commands... and doesn't play any sound.

Here is an example of what I'm trying to do:

    {
        "match": ".*",
        "cmd": "paplay '/home/sainoba/Music/knob.ogg",
    },

paplay '/home/sainoba/Music/knob.ogg' works fine if I run it in a terminal
