The sound coming from my computer's built-in speakers are extremely quiet, much quieter than what they originally were when I purchased the laptop.
Sound from all other outputs are completely normal. Using earbuds, headphones, or external speakers all create sound at a normal volume. However, to hear sound at an even audible volume through the computer's speakers, I have to turn the volume to the max, and it's still somewhat quiet.
I have tried uninstalling and reinstalling all the sound drivers and nothing works.
Any help would be appreciated, thanks!

Welcome to the Community
When you uninstalled the Sound driver, have you tested the sound using the generic windows driver? If you have, can you enable loudness equalization on the sound enhancements and observe (see image below) and enable dolby (Dolby Tab):
Let me know your findings,

In the Device Manager, here's what it looks like when the sound driver is installed / uninstalled:
When it's set to "High Definition Audio Device", that means it's using Windows' inbox (generic) driver.

Have you restarted the PC or did a "scan for hardware changes" under the device manager after you uninstalled the sound driver?
The Nvidia High definition Audio is most likely for your HDMI (when you connect to a TV, it outputs video+audio).

I have gotten the generic sound card to work. Checking the "loudness equalization" does not seem to help the speakers though, being just as quiet as before. Earphones and other outputs still work though.

If the generic sound driver still outputs low sound during a music/video playback (i.e. youtube, pandora, etc.) then it's not a driver issue. In this case, it could be something hardware or updates that got pushed to the OS itself.
To isolate the OS issue, backup important files and try to:
1. Perform a System Restore to undo any changes on the OS that might have caused the issue (windows updates, drivers, etc)
2. Press the One Key Recovery button to restore the unit from factory settings
If the problem remains, the root cause is possibly the speakers or the wires that goes to the speakers and you need to contact lenovo for service.
