One other note and questions on this.  I did note that with the
installation of ALSA 1.0.19, I have an additional entry in the output
of 'aplay -L' which wasn't there before.  Now, the last three entries
are:

iec958:CARD=NVidia,DEV=0
    HDA NVidia, ALC888 Digital
    IEC958 (S/PDIF) Digital Audio Output
hdmi:CARD=NVidia,DEV=0
    HDA NVidia, NVIDIA HDMI
    HDMI Audio Output
null
    Discard all samples (playback) or generate zero samples (capture)

Before, I didn't have the hdmi entry.  I could, however, use "hdmi" as
an output device for speaker-test or mplayer and get sound over hdmi.
It just wasn't listed here.  I am wondering if someone who has the
same ALC888 controller (preferably with the GeForce 7050 chipset) and
has AC3 passthrough over HDMI working can post their output of 'aplay
-L'.  The reason I ask is that mine lists iec958 as being a Digital
Audio Output, but hdmi is only listed as being Audio Output.  I don't
know if that is relevant or not, but I would be interested in seeing
what another mobo has to say about it.
Thanks,

Joel
