I Screwed Up My Audio Drivers. Please Help

I was playing around trying to get my mixer to do something that it is incapable of doing. In this process I thought my realtech audio drivers were out of date so I downloaded the asla drivers for it.

Thats where the story turns bad for me. I am guessing during the configure portion of compiling wiped out everything, and failed to install.

I have went back to USB audio out of my mixer (which was working before I messed up) but there is absolutely nothing for input or output.

PLEASE HELP!! I dont know what to include in this post to help. I am sending my lsmod info. There is no snd_ loaded in it. I have just switched from windows to linux. I am running ubuntu 18.04.

So, unless you blacklisted something, a kernel reinstall and firmware reinstall will fix this.

 sudo dpkg --reconfigure <deb package>

or if that scares you

 sudo apt update && sudo apt -f install <deb package> 

If you are running a custom kernel, just go back to the distro provided at boot.

Linux has driver snd_hda_intel for Realtek and other onboard audio devices

hwinfo --sound or alsa-info.sh would show audio system information

But likely will confirm no snd_hda_intel driver loaded for devices that need it

You can probably get information about working audio configuration by booting from a Live USB Linux ISO

Suggest Reinstall of ALSA may get it working again, but may need some related packages reinstalled too
