It does not sound good, literally, if the left speaker of your PC does not work.
You may not be receiving output from the left speaker unit for a few reasons. There can be inappropriate sound settings, faulty audio drivers, or simply fault in the hardware. However, before that, look for a volume change button or scroll bar on your left speaker and see whether it is at its lower level. If it is, try raising the volume.
But you probably already did that. So, we are here to help you fix the issue on your PC’s left speaker.
Ways to Fix Your Left Speaker

If it works there and you are sure it is not the speaker, let’s look at the fixes right away.
Inspect the Speaker Connection and Port
Sometimes the left speaker can fail to emit sound due to loose connections. For instance, if you insert the audio jack to only half its length, you may not hear sound from one of the speakers. So, you should inspect the speaker cables and the ports to check their integrity.

Change Audio Mode
Speakers and your PC coordinate to provide the best sound experience. To do this, there are several audio modes, especially Mono and Stereo. Mono mode combines the sound from both into one, while Stereo mode sends audio from each speaker separately.
Sometimes, the mono mode may fail to combine the channels, or the Stereo mode may not receive sound from both ends. Few users have reported that changing the audio mode fixed the issue. So, you can attempt to do that.
