My searches lead me to the Pywin32 which should be able to mute/unmute the sound and detect its state (on Windows 10, using Python 3+). I found a way using an AutoHotkey script, but I'm looking for a pythonic way.
More specifically, I'm not interested in playing with the Windows GUI. Pywin32 works using a Windows DLL.
so far, I am able to do it by calling an ahk script:
In the python script:
import subprocess
subprocess.call([ahkexe, ahkscript])
In the AutoHotkey script:
SoundGet, sound_mute, Master, mute
if sound_mute = On ; if the sound is muted
Send {Volume_Mute} ; press the "mute button" to unmute
SoundSet 30 ; set the sound level at 30
You can use the Windows Sound Manager by paradoxis (https://github.com/Paradoxis/Windows-Sound-Manager).
from sound import Sound
Sound.mute()
Every call to Sound.mute() will toggle mute on or off. Have a look at the main.py to see how to use the setter and getter methods.
If you're also building a GUI, wxPython (and I would believe other GUI frameworks) have access to the windows audio mute "button".

How can I send keystrokes and mouse movements to a specific running program through its PID. I've used both pywinauto and pynput, and they work great, but I want to send keys to a program that is not in focus. I found this question: How to I send keystroke to Linux process in Python by PID? but it never explains what filePath is a path to.
If you could help solve for this example, that would be great! I want to send the "d" key to an open Minecraft tab for 10 seconds, and then send the "a" key for the next 10 seconds and stop. I would need this to be able to run in the background, so it could not send the keys to the computer as a whole, but only to the Minecraft tab. I am on Windows 10 by the way.
Any help would be appreciated!
Pretty sure you won't be able to, at least not easily let me explain a little bit how all of this works.
Lets start with the hardware and os, the OS has certain functions to read the input you give the computer. This input goes into a "pipe", the OS is reading input, and putting into the pipe, on the other side of the pipe there may be an application running, or it may not. The OS typically manages this (which app to put on the pipe listening) by defining which app/window is active. Apps access this pipe with the API given by the OS, they read the input and decide on it.
The libraries you cited above, change the values of the keyboard and mouse, in other words, they make the OS read other values, not the real ones, then the OS puts them in the "pipe", and are read by the app that is listening on the pipe (the one active). Some apps have their own API's for this, but I would guess Minecraft doesn't. If they don't have an API, what can you do? well, as I said, nothing easy, first of all "hacking" the app, in other words change it to listen to some other input/output rather than the one given by the OS, (this would be you making your own API). The other one would be you changing the OS, which would also be extremely hard, but maybe a tiny bitty easier. It also depends on your OS, I think Microsoft does offer input injection api's
So, simple options, first, run a VM with a GUI and use pywinauto, pyautogui, etc. The other option would be if you can run it in the browser, do so, and use something like Selenium to automate the input.
Quick note, why does selenium works and the browser can read input in the background? Easy, it's not, it just executes the code it would execute if it would have read the input! javascript, cool isn't
With ahk you can do this with Python+AutoHotkey
pip install ahk
pip install "ahk[binary]"
from ahk import AHK
from ahk.window import Window
ahk = AHK()
win = Window.from_pid(ahk, pid='20366')
win.send('abc') # send keys directly to the window
Note that some programs may simply ignore inputs when they are not in focus. However, you can test this works in general even when not in focus by testing with a program like notepad
Full disclosure: I author the ahk library.
is it possible to send the alt+tab for switch to last window with AutoKey ?
i tried without success:
keyboard.send_keys("<alt>+<shift>+<tab>")
Or forward window:
keyboard.press_key('<alt>')
keyboard.press_key('<tab>')
keyboard.release_key('<tab>')
keyboard.release_key('<alt>')
Or backward window:
keyboard.press_key('<alt>')
keyboard.press_key('<shift>')
keyboard.press_key('<tab>')
keyboard.release_key('<tab>')
keyboard.release_key('<shift>')
keyboard.release_key('<alt>')
result: no error but only moves the tab count inside the editor.
TL;DR: Not directly with our API.
The AutoKey API talks directly to the current active window. So, sending events targeted at the desktop (DTE) will only work if the current active window recognizes them as such and either forwards them to the DTE or emulates what they do.
However, since AutoKey scripts are written in full Python 3, if you can figure out how to do it yourself in Python, AutoKey can run it for you. And, if some other solution is available, you can run it from within an AutoKey script using the subprocess module.
Autokey's Window class allows you to activate a window by name (via wmctrl), among other functionality. Something in that class may be what you're looking for.
I'm trying to write a simple python script to stop the music being played by a Mac. I found some code that emulates the media buttons from the accepted answer here: emulate media key press on Mac.
Triggering the play/pause button works perfectly, but I only want to do so if there is music currently playing. Otherwise it turns on the music (the opposite of what I'm trying to do. Is there any way to get this information from the system?
I need to check if music was actually playing beforehand so I can know whether to resume it later.
If your use case is macOS specific, you can call AppleScript via Python:
import subprocess
subprocess.call(['osascript', '-e', 'tell application "iTunes" to pause'])
In python 3.4 , I was trying to open a "wav" file using vlc in Linux. Here is my code:
import os,time
os.system("cvlc audio/some.wav")
time.sleep(3) #audio was one and half sec
a = 3+3
print (a)
It plays the audio but then doesn’t do the rest. What should I do to make it do them? more precisely what should I do to close the vlc program?
With solving the problem it will also be very grateful to know is there any easier way to play audio within the code specifically in python 3.4?
(platform independent code will be even more grateful!)
So the VLC player doesn't exit. The VLC player has a command line argument to close the player once the song/video has been played.
Playlist
These options define the behavior of the playlist. Some of them can be overridden in the playlist dialog box.
--play-and-exit, --no-play-and-exit
Play and exit (default disabled)

Can you try the following?
os.system("cvlc audio/some.wav --play-and-exit")
I am trying to record a live stream in vlc. It is easy if I use the GUI, just clicking on Convert/Save in the Media option, and after that choosing the stream address in the Network tab. I wanted to do the same thing in a C/C++/Python program. In case of a C program, I used Visual Studio but on writing #include<vlc/vlc.h> it says the file cannot be included. Then I downloaded the source from git but still it is not working. What to do?
You can save a stream using commandline arguments:
vlc scheme://host/stream.xyz --sout file/muxer:stream.xyz
and thus, call it using some kind of exec() (or its windows equivalent).
Then, the following answer: https://stackoverflow.com/a/19484168/1290438 shows how to open a stream in VLC in python:
import vlc
i = vlc.Instance('--verbose 2'.split())
p = i.media_player_new()
p.set_mrl('rtp://#224.1.1.1')
p.play()
So I guess, at worst, you can give the --sout argument to vlc.Instance, or at best there's a method on the instance to set up stream output.
In my humble opinion, using C/C++ for such a simple task is like killing a fly using a bazooka…
