 John-
Maybe.  It brought up the possibility that I need to migrate to a newer
NVIDIA driver blob.  I'm currently running with V304.135 since that was
suitable for the on-board video, but having migrated to a GT 710 adapter,
maybe I need something newer?  Synaptic lists versions up to V384.111.  As
another indicator that this may be appropriate, when I ran nvidia-settings,
there was no information about the GT 710.  I'll have to check which driver
version(s) are appropriate for the GT 710.

Daryl-
To be more accurate, I'm running the MythBuntu spin, so I don't have the
Ubuntu desktop, but rather the XFCE4 desktop, so the directions you
provided don't apply.  However, to your point, I have been through all of
the XFCE Settings Manager options and the xfce4-mixer with nothing that
helped or looked appropriate, unless I missed a "camouflaged" option. :-(
Maybe there's another XFCE4 add-on that I need to get in order to duplicate
that functionality?

Michael W-
I mentioned earlier in this thread that I had worked through those, without
luck.  Many of the most promising ones indicated in the help text at the
bottom that they had "No connection detected", but I tried them anyway,
just in case.  :-(  As noted in my reply to John, above, maybe updating the
NVIDIA driver will help?

Mike C-
The old TV was an old S-Video connected CRT with RCA jacks for the left and
right audio channels (which I actually fed into my stereo system instead).
This is my first venture into display technology from this millennium.  As
for the HDMI settings on the new system, they better take audio from the
HDMI ports because there are no separate audio in ports, hence my efforts.
:-)  Happily, the TV works when connected to the cable box via HDMI, so
that doesn't seem to be the problem, but thanks for the suggestion, anyway.

My thanks to all for the suggestions and advice so far.  Inspiration is a
wonderful thing.



Better yet, SOLVED!

It indeed turns out that V304.135 was _way_too_old_ a version for the new
video adapter, and maybe for the others I've been trying.  I'll have to go
back and investigate when time permits.  Upgrading to the V384.111 version
of the NVIDIA proprietary driver fixed the problem so that the audio
settings in mythfrontend recognized the presence of the TV connection and
audio now flows to the destination!

Thanks to all for your help in getting this resolved.
