presumed that I could only run the chrome browser within a D.E. in order to
test the problem of flashplayer running a video with sound output? It was
not clear to me how to do that unless I had a different D.E. running (i.e.
not KDE) or window manager within which to test it? Presumably I can't test
from a text console, or can I? - apart from the command which works from a
Konsole terminal within KDE as I originally posted:

aplay -D plughw:0,7 /usr/share/sounds/alsa/Front_Center.wav

So presumably I need to set this into either ~/.sound or /etc/alsa.conf and
try to test from a text console as:

aplay -D /usr/share/sounds/alsa/Front_Center.wav

and if that works then the default channel will have been set as the HDMI
channel and then switch back to trying from KDE ?

Certainly if I can't get that to work as a solution and re-enable KDE then
of course I can follow the wiki advice on setting up pulseaudio and testing
that route for a possible solution. I will report back on how I get a
working solution if that will help others with this kind of problem. As I
said in my original post I can get sound output for everything else except
flash output from the browser.

Anyway thank you for the suggestions which I will follow up.
