Seeing what appears in the kernel's output when you plug in each port

I had heard modules to provide virtual PCM files for audio CDs, but it
is usually considered a bad idea, since reading reliably an audio CD
requires a lot of care (the "paranoia" in "cdparanoia").

(I am pretty sure we are not related ;-)
