Usually this indicates that there is some initialization that's done by the BIOS that doesn't happen in the case of "pnp-os=yes" because the hardware expects the OS's driver to do the work. The main thing I've seen with motherboards that behave this way is power management: they expect the OS to turn the power on before it tries to use the device. Probably the chip itself is on, and the output amp is turned off. I mentioned this before in a similar thread; if you hack the driver to turn the power on, it should fix this for you. I've seen the same thing with a USB keyboard and mouse, on one motherboard... -- Terry
