+To play audio in this lab, we will need to add the kernel modules to
+the root filesystem generated by Buildroot, and make sure that the
+\code{snd-usb-audio} module is automatically loaded at boot time. Note
+that it would be better to have the Linux kernel built by Buildroot,
+so that the kernel modules are automatically installed into the root
+filesystem. But for our quick experiment, we'll just copy the kernel
+modules we already have.
So, let's prepare an overlay directory (in the main lab directory)
that Buildroot will use after building the root filesystem:
