I googled some info about the nvidia G84** or G86** graphics core.
They got the audio signal from the external audio device through spdif.
For Dell M1330, the spdif configuration for the stac92** codec looks
well, maybe the graphic driver can control whether the audio signal is
allowed to transfer through the HDMI port?
