Oh, I see. I thought you couldn't hear the CD player whether or not you
are docked. You can see your ACPI view of the device tree with:
acpidump -d | grep Device
You'll probably have a DCK (dock) device that has some sound device
under it. We don't have much docking support currently but if you boot
while docked, devices on it should work fine. I have patches for basic
docking support but the problem is there are many device drivers that
don't handle this properly yet. For instance, if you have a floppy
drive bay in the dock, the fdc(4) driver doesn't know yet how to handle
an undock event. We're just lucky that most laptops so far let the BIOS
handle things.
