I couldn't find any soundboards compatible with Linux that fit my standards, so I made my own that uses the numpad.

• PyYaml for easy reading and writing of configuration file(s).
• TKInter to create the interface. On Ubuntu, do sudo apt install python3-tk to install it.
• PyOpenAL to play sounds.
• PyOgg to allow PyOpenAL to play .ogg files.

Two soft requirements would be pavucontrol (PulseAudio Volume Control, to control where output is redirected) and the sister project to this, the Pulseaudio-Loopback-Tool. (to create loopbacks, null sinks, and remapped sources)

Install pavucontrol on Ubuntu by doing sudo apt install pavucontrol
Install Pulseaudio-Loopback-Tool by clicking the link and downloading that project.

• Supports (theoretically) unlimited amounts of folders and (theoretically) unlimited amounts of audio files.
• Use buttons on the GUI to switch folders and play the first 9 mapped audio files.
• Click on the lists to switch folders and play any audio file.
• Use numpad keys to switch folders and play sounds no matter what application you have selected!
• Multiple audio threads allowing for multiple different or same sounds to play at once!
• Ability to instantly kill all outgoing audio.

Clean way: follow steps normally.
Dirty way: Do step 1, skip to step 4, and follow steps normally from then.

1. Download this repository and unzip if need be.
2. In the repository folder, perform python3 -m venv venv to make a Virtual Environment.
3. Activate it using source venv/bin/activate
4. Install requirements via pip3 install -r requirements.txt
   • If it fails to install, try pip3 install wheel && pip3 install --force-reinstall -r requirements.txt
5. Run the soundboard either by doing python3 start.py or ./start.py

The "Clean" installation keeps the requirements of this project away from your local Python 3 installation, making sure that these requirements don't interfere with the requirements of your other Python programs. The cost is that more work has to be done to start up the project, requiring you to source venv/bin/activate before starting the soundboard up.

The "Dirty" installation has the requirements installed into your local Python 3 installation, possibly interfering with other Python programs. The upside is that it is easier to start the project, and double clicking start.py to start the soundboard is easily possible.

Small list of "How to do this common thing", if you either have a question or found something that you think belongs here, make an issue for it and I'll probably add it!

Three different ways, actually:

1. Click the sub-folder on the left that contains the sound that you want to play, then click the sound on the right.
2. Use the buttons to go back and forth between folders, and play sounds that are mapped to those keys.
3. Use numpad controls to simulate pressing the buttons.

Top middle of the soundboard is a pulldown. In the pulldown is all the input devices the soundboard found in /dev/input/by-id. Select the keyboard that you want the soundboard to listen to, press the "Use Event File" button, and the numpad on the keyboard should now trigger the soundboard buttons.

Ten not enough for you? Edit soundboard_config.yaml with any text editor and change max_sounds from 10 to whatever number you want. Increasing this number will not decrease performance, it's playing many sounds at once that will.

Using pavucontrol you can set the soundboard to output to any available sink, and sinks can be created by PALT. (PulseAudio-Looback-Tool) Ideally, you'd have the following basic setup:

1. Using PALT: Create a sink called "Audible_Layer"
2. PALT: Remap "Audible_Layer" to "Output_Mic"
3. PALT: Loopback "Audible_Layer" to your speakers/headphones, so you can hear the soundboard as well.
4. Using pavucontrol: Set your recording application to use "Output_Mic"

If you haven't run the soundboard yet, run it once to create the config file.
Edit soundboard_config.yaml with any text editor and change "Sound Files" to the path of the desired root folder, either relative to where you are executing start.py or absolute.

Simply add more folders in the root folder! It's alphabetically sorted in the list, so adding 1, 2, 3, etc. to the beginning of the folder name will force it to go in that order.
There is (theoretically) no limit to how many different folders you can have.

Put audio files into into the sub-folders. Just like the folders, it's alphabetically sorted in the list.
Again, there is (theoretically) no limit to how many different audio files you can have.

Rename the sound file to have a number and a space at the beginning of the filename, with the number being what number button you want it mapped to. If you want a sound called hey.ogg mapped to the 3 button, rename it to 3 hey.ogg
Renaming it to 3hey.ogg or 3_hey.ogg will not work, the space is required.
If multiple files start with the same number, the soundboard will pick the first one it finds.

Well, if its not listed below here, submit an issue for it and it will get fixed as soon as possible!

It's a configuration setting in OpenAL, edit the config file and change allow-moves to true. For example:

1. sudo nano /etc/openal/alsoft.conf
2. Control + w, allow-m, press enter.
3. Find #allow-moves = false and change it to allow-moves = true
4. Control + x, y, enter.

The change should take effect immediately, but may require a restart of the soundboard.

If on Ubuntu, do sudo apt install python3-tk to get TKinter for Python3. Else, use pip to install it or find instructions for your distribution.

As far as I know, OpenAL supports .wav, but because of pyogg it also supports .ogg files. The soundboard will reject all non-.wav/.ogg files it finds. If OpenAL can run more than those files, make an issue for it and I'll update it.
If you are impatient, edit SOUND_FILE_EXTENSIONS in soundboard/storage_module/storage_manager.py and add the file format there to make it show up.

If you have any questions, concerns, ideas, etc, make an issue for it! I'm all up for recommendations on how to make this better.
