How to change the master volume in PulseAudio programmatically?
1
You can change the master volume within the terminal itself by using the command shown underneath.
amixer -D pulse sset Master 5%+
However, when I tried to execute the following code in Python, the following error is shown.
No protocol specified
xcb_connection_has_error() returned true
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused
amixer: Mixer attach pulse error: Connection refused
And here is the code producing the error above.
os.system("amixer -D pulse sset Master 5%+")
How does one resolve that error?

The "unable to connect" error can mean: pulseaudio is not running or permissions issues exist. "pactl" may be more appropriate for controlling pulseaudio. Try determine what output you're trying to control by running: "pactl list sinks". Review the output of that command to determine the sink number. Then run something like "pactl set-sink-volue 3 +5%" (where "3" is the sink # on my machine for "Built-in Audio Analog Stereo"). One point to note: sink numbers can change across reboots, so it is worthwhile to research how to accomplish the same thing with sink names instead of sink numbers.

I have tried pactl also but getting same errors.@joat

Pulseaudio is running? Are you (or your script) running pactl/amixer as the logged in user (not root)? That's about all that I can think of.

Of course it's working in terminal but my main issue is that it's not working with Python code.@joat

It's must be a permissions issue. 'import os;os.system("pactl set-sink-mute 3 1")' works if I run it in a terminal or in a script. When you run amixer, do you have to select the sound card before doing anything else?

Finally, I got a solution to my own problem which is shown below
import subprocess
proc = subprocess.Popen('/usr/bin/amixer sset Master 5%', shell=True, stdout=subprocess.PIPE)
proc.wait()
