I am trying to convert an Evolve III Maestro laptop into a Linux machine on the Xubuntu distribution.
After resolving some issues with the WiFi adapters, I am running into an issue where my machine isn’t able to output audio to the speakers or headphones (though it is able to output to Bluetooth).
I believe that downloading and installing Realtek HD Audio Drivers will help, but Realtek appears to have overhauled their website and has removed their downloads for Audio Drivers.

Are there any alternative places to download these drivers for my computer?
Additionally, for those with Linux experience, does this seem to be an issue with the drivers?

Here is some data that might be useful.

pacmd list-cards returns 0 cards.
