[mythtvnz] No HDMI sound output in desktop (Mythtv ok)

[Paulgir]

Hi all

I have been trying to get HDMI sound back for the Mythbuntu desktop by
modifying asound.conf.
It seems,looking at my notes that,

pcm.!default {
	type hw
	card 1
           device 9
}

worked in the past but it does not now.

The command speaker-test -c 2 -D hdmi:CARD=NVidia,DEV=3  Will give me
sound through the speakers.But speaker-test -c 2   won't and I get nothing
when using a browser or VLC.
I've tried different numbers for Device= and looked at lots of threads but
I'm not having much luck.One question: do I need to reboot after modifying
asound.conf?

Cheers  Paul
