How

- Reach for headphone or speakers.
- Turn volume knob to zero.
- Observe your growing anger at your own inability to control the car without auditive feedback.

Sorry for the 'funny' answer, but can you be more specific what you actually want to achieve? To drive in a racing sim you need all the feedback you can get, and sound is a big part of it.

Probably a 3rd party sound application. The current sounds dont seem to change volume that widely, I dont know if it's really possible to replace LFS sounds anymore

Shift + N disables ALL LFS sound

Shift+N
