Yesterday, my laptop worked great with sound. Today, it has no sound at all. I've made no changes that I know of since last successful audio use.
I have looked at the information found here:
https://www.linuxliteos.com/forums/index.php?topic=574.0 It does not appear to be my volume keys on the keyboard and I also verified that all audio levels are set to 100 through the sound settings. As music is played, I can see the sound bar moving up and down as if it recognizes the audio.
Here is the output of my lspci (lspci -v | grep -A7 -i "audio"):

It seems like it just stopped working. Anyone have any ideas why this happened and how to get sound back on? Thanks!
