Try updating your computer: Press Alt and F2 (may require the Fn key to be pressed) key, then type gnome-terminal and press Enter. A purple window will pop up. Into it, type:
sudo apt update && yes | sudo apt upgrade && yes | sudo apt --purge autoremove
Then press Enter. Type in your password, not the root user's password. (If you did not set up a sudo user, do su -c "usermod -aG sudo username", type in the root user's password, and try the sudo command again.) Your computer may install a driver automatically.
Look at Jag Jenki's answer too.
Try to find drivers online (from Lenovo) and install them. (I'm having difficulty finding them but they seem to exist after some research.) They don't exist.
Edit: Looks like someone had the same problem and fixed it by updating the kernel: https://unix.stackexchange.com/a/785062. You may not have to update the kernel manually, maybe using the script mentioned here - https://cloudspinx.com/how-to-install-linux-kernel-on-ubuntu/ - or if it goes down - https://askubuntu.com/a/1388117/2021441. Or you can wait for the next (LTS?) release (which I'm not even sure will upgrade the kernel). Also, looking at the Ubuntu certified page Jag Jenki shared, your computer seems to support 22.04, not 24.04. Also, the hardware details mention nothing about a microphone. Consider using an external microphone for now.
