Hi Alon Kadouri,
Your system may be missing the required audio drivers.
Please visit your manufacturer's support page to download and install the correct audio drivers. You may also need to install the chipset drivers to ensure full compatibility.
If you have trouble finding the right files, feel free to share your laptop or motherboard model, and I will help you locate the correct drivers.
If you have any additional details to add, please do not hesitate to let me know.
