How To Create A Virtual Audio Cable For Zoom In Linux Using Python And PulseAudio
Creating a virtual audio cable in Linux using Python involves manipulating the PulseAudio sound server to route audio between applications. Here’s a step-by-step tutorial on how to achieve this:
Step 1: Install Dependencies Make sure you have Python installed on your Linux system. Additionally, you’ll need to install the
pulsectl Python packages. You can install them using the following command:
pip install pyaudio pulsectl
Step 2: Import Required Modules Create a new Python file and import the necessary modules:
Step 3: Create a PulseAudio Context Create a PulseAudio context object to interact with the sound server:
pa = pulsectl.Pulse('virtual-audio-cable')
'virtual-audio-cable' with a suitable name for your virtual audio cable.
Step 4: Find Source and Sink Devices Use the PulseAudio context to find the source and sink devices you want to use for audio routing. You can list all available devices using the following code snippet:
for source in pa.source_list():
for sink in pa.sink_list():
Identify the names of the source and sink devices you want to use and take note of them.
Step 5: Create a New Output Create a new output in PulseAudio using the selected source and sink devices:
source_name = 'YOUR_SOURCE_DEVICE_NAME'
sink_name = 'YOUR_SINK_DEVICE_NAME'
source = next(s for s in pa.source_list() if s.name == source_name)
sink = next(s for s in pa.sink_list() if s.name == sink_name)
pa.source_output_new(source, sink, stream_name='virtual-audio-output')
'YOUR_SINK_DEVICE_NAME' with the names of your chosen source and sink devices.
Step 6: Start Audio Stream Start the audio stream between the source and sink devices:
Step 7: Cleanup and Termination To clean up and terminate the virtual audio cable, make sure to remove the created…
