What's the way to know polarity is correct, except trying both
positions? For now, the arrow on the plug is facing outwards.

You wrote:

"If you have selected to use only the digital output, you are NOT
going to get sound out of the analog outputs on your computer. You
do know that you can not hook speakers directly to the digital
output, right?"

... but i suppose that's not it.

I right clicked on the Speaker in the top panel, and tried every
setting with digital in it: it doesn't work. I set alsamixer to have
both analog and digital S/PDIF output enabled, then only digital out.
No result. I suppose it is normal that you can't rise the volume since
the TV controls the volume, the HDMI cable feeding a preamp signal.

Please note that, since Twinview doesn't work, I use 2 Xscreens. It's
not possible, for instance, to run Firefox or any other applications
on both screens at the same time.

It's impossible to have the notification area on the TV. So, I can
only hope that the settings in the notification area are valid on the
TV. But it seems so since what is in Klipper -- that I use with GNOME
-- can be copied to gedit on the TV screen. So, this seems OK.
