I am new to Linux and am trying to start using Linux on my 2017 iMac Pro that has an Intel Xeon W chip. I was able to successfully install Ubuntu 22.04.4 and dual-boot, however, it does not look like my sound card is being recognized. For output I'm only seeing Dummy Output, and no input options. I have tried plugging in my headphones, but those aren't recognized either. I have tried a bunch of recommendations out there while perusing Google but have had no luck. If it helps, I have run this command and here is the output:
sudo lspci -vv | grep -i audio
