I've got an ASUS UX51VZ-DH71, and it has a built-in HD4000 and NVidia Geforce GT650M. After using acpi_call to turn on the card, I'm able to start X on the NVidia card and output through the HDMI port. However, I can't make audio output to work.
There is only one Intel HDA device on the PCI bus, and it only contains a Realtek codec, which outputs to the internal speakers and headphone.
It looks like that when HDMI port is used in Windows, a new NVidia HDA device shows up on the PCI bus to which the NVidia display card was attached. However, under FreeBSD, even if I unload and load the snd_hda driver, no new device shows up.
Anyone succeeded in audio output through HDMI on a similar device? Is it possible to force a PCI bus to rescan?
