Comment # 65 on bug 1224457 from wlms

The following output is from an ASUS B350-Plus with an AMD 5700G.  Same CPU as
mine, ASUS B350-Plus mobo uses a Realtek ALC887, the same as my B550-Plus.  The
B350-Plus computer is running Ubuntu 24.04.

This is presumably what mine should look like.  I'm beginning to wonder whether
I have some kind of hardware fault on the B550-Plus motherboard itself. 
Unfortunately, Windows is the only way I have of testing it.
