Vehicle audio does not produce in Carla Client (In Pygame window)

[inrkumar22]

Thanks for contributing to CARLA!

If you are reporting an issue, please use the following outline:

CARLA version: 0.9.14

Platform/OS: Windows

Problem you have experienced: I have integrated engine audio with one of the Carla car model using UnrealEngine Editor. When I executed 'generate_traffic.py' file with the same car model, we heard the engine sound in Carla Simulator inside the UnrealEngine. But when I executed the 'manual_control.py' with the same car model, it does not produce any engine audio on the PyGame Window.

What you expected to happen: I was expecting the engine sound on the PyGame Window for that car model.

Steps to reproduce:

1. Integrate the audio file using Sound Cue. You can take help from the youtube vidoe : https://www.youtube.com/watch?v=0X2KgGakK24
2. Once you are done. You can execute generate_traffic.py script in carla simulator inside unreal engine 4.27.2.
3. You can hear the car engine sound in between if run for few minutes.
4. Now run the manual_control.py script with the same car model. It pops out the PyGame window, You can play with the car but NO audio.

Other information (documentation you consulted, workarounds you tried): I gone through the Client PythonApi to fetch any additonal sensor data which can help here.

If you are asking a question please make sure your question was not asked before by searching among the existing issues and checking the CARLA forum https://github.com/carla-simulator/carla/discussions. Also make sure you have read ourdocumentation and FAQ at http://carla.readthedocs.io.

If your question is about creating content (assets, levels) you'll most likely have all the info you need in the Unreal Engine's documentation https://docs.unrealengine.com

Please, keep the threads focused and single-themed. Make them easy to find for everyone.

Any kind of help is really appreciated.

Hi @chirudeep001 @inrkumar22, the manual_control.py script is a client which connects to the Carla server. It streams sensor data like images using a camera which can be placed around a vehicle. However, there is no sound sensor or similar to stream your sound from the server to your pygame client.

Hello! We are not transmitting audio to the carla client. It is not expected to implement this feature. If someone in the community contributes to it, we will appreciate it.
