Realtek HD Audio low and bad quality sound after Windows 10 upgrade

I am using Sony Vaio laptop. Yesterday I upgraded from Windows 8.1 to Windows 10.

After upgrading, the sound quality of Realtek HD Audio has become very bad and extremely low. There is no bass and the sound is distorted and screeching. I have tried updating the Realtek driver but that didn't change anything.

How can I fix my Realtek HD Audio after upgrading to Windows 10?

 

Realtek HD audio - low volume

Something really unexpected happened after a seemingly innocent thing - I connected external microphone to a front panel jack, and everything started sound at a low volume. I disconnected then the mic, and put it back to the back panel jack. Low volume
remained. I tried uninstalling drivers, installing Windows 8.1 drivers in compatibility mode, I played with pretty much all settings of Realtek HD Audio manager, Sonic Studio, Control Panel's sound settings. Nothing helped. Such a puzzling story! I hear it's
due to some Realtek software/hardware bugs.

Anyone has a workaround?

 

Realtek HD Audio low and bad quality sound after Windows 10 upgrade

skitchpatterson3's and bekce's answers helped me get started, but I needed to tweak the steps a little bit. I bought an MSI box which had Realtek HD Audio driver. The first thing I needed to do was update the sound driver in Device Settings. After that, I opened Realtek HD Audio Manager and navigated to Sound Effects, which wanted to launch Nahimic 2. The Windows 10 Aniversary update broke Nahimic 2.2, so I needed to download 2.3 from their Facebook page here. The Mega link looks sketchy, but I scanned it with Norton and it looked safe. After updating Nahimic and restarting my computer, my headphone audio was working perfectly.
