Run pactl with preset language

[wgorecki]

pactl runs with system language while script expects english. pactl has to be ran with language set to english. Otherwise, it will not update changes such as volume level, mute on/off.

Is this the only call where LANG=$LANGUAGE is needed? I call pactl a few more times in the script too.

[wgorecki]

Yes. pactl is called multiple times but only two calls rely on it's output. First call is on line 144th: inputs=$(pactl list sink-inputs short | cut -f 1) inputs contains sink ids which are numbers, no need to specify language. Example:

10:09:30 [~] > pactl list sink-inputs short | cut -f 1
53
62

The second one is pactl subscribe

When used with english:

on 1st terminal
10:19:05 [~] > LANG=en pactl subscribe | grep -e "on card" -e "on sink" -e "on server"
Event 'change' on sink #7

2nd terminal
10:19:18 [~] > pactl set-sink-mute alsa_output.pci-0000_26_00.1.hdmi-stereo-extra1 0

When used with system language:

1st terminal
10:19:57 [~] > pactl subscribe | grep -e "on card" -e "on sink" -e "on server"

10:20:06 [~] > 

2nd terminal
10:20:02 [~] > pactl set-sink-mute alsa_output.pci-0000_26_00.1.hdmi-stereo-extra1 0

Example for polish language:

10:17:26 [~] > pactl subscribe
