Why Your Left Speaker Isn’t Working?
Your left speaker isn’t working due to a cable issue or any kind of broken jack. A loose plug connection to the power source can also throw such exceptions.

Cable Problem: If you are using some old cables, then they are not capable of carrying out the signal efficiently. Sometimes a cable inside is torn. If this is your case, you can’t eliminate this issue without replacing it.
Broken or damaged jack: A broken jack is very much common if you don’t maintain the cables and it’s parts very well. A damaged jack can’t input the signal properly. Thus a broken jack must be replaced to fix your issue.
Loose plug connection: A multiplug has different types and sizes of ports. Sometimes the plug doesn’t get attached properly to the ports, and the connectors get disconnected from the ports.
This causes an improper power supply to your speaker. If it is true for you, both of your speakers don’t have enough power to operate.
Corrupted driver: The driver is very much essential stuff to operate your device properly. If your driver somehow gets manipulated by anyone or by a virus, then it will be corrupted and unable to function properly. Corrupted drivers don’t work fine with the OS and the devices also.
Mono audio setting: Mono audio setting is something that provides you to operate only one part of your speaker. So if this setting is on your Windows PC, then it will be the main and final culprit for this inconvenience.
