 Can you see the terminal output now? I find Dell Support very frustrating where I am asked to post a snapshot of terminal into Google Drive and share it in order for Dell Support to see it.  If the ability to insert an image onto a post is available, all users including Dell Support staff should see it. Not this run around, do this and do that just to view a simple image.

From the terminal, the following audio drivers are installed.
