I have a 780g hdmi mboard also, I think a gigabyte GA-MA78GM-S2H.
I eventually got sound through hdmi by upgrading to alsa 1.0.16. I can't remember if I had to have fglrx loaded. I also don't think it worked for me until I reached the 2.6.25 kernel. Using 2.6.25.11 now.
Catalyst 8.6 and 8.7 not working very well with my mboard. Went back to 8.5.
You have to enable ("m" to unmute) hdmi in alsa
Sound is not always consistent. I can play a mp3 using xine from command line (have the sound option in ~./xine/config :
Code:
# device used for mono output
# string, default: default
audio.device.alsa_default_device:hw:1,0
# device used for stereo output
# string, default: plug:front:default
audio.device.alsa_front_device:hw:1,0
But if I start song and restart, sound sometimes gets redirected to front headphones.
Can't (yet) get sound via hdmi using gui of mplayer.
It sometimes works from command line if I have ~./mplayer/config as:
Code:
alang=eng #Use English audio
#slang=eng #Use English subtitles
#ao=alsa
ao=alsa:device=hw=1.0
#vo=x11
vo=gl
This has sometimes worked
Code:
mplayer -ao alsa:device=hw=1.0 /dev/dvd
I'm also running optical cable to receiver. This is working well.

In xine, for time being change video to xshm to get past the xv problems. Although for whatever reasons, xv has started to work for me. Maybe due to changes in xorg.conf
Code:
Section "Device"
Identifier "aticonfig-Device[0]"
Driver "fglrx"
# === Video Overlay for the Xv extension ===
Option "VideoOverlay" "off"
Option "TexturedVideo" "on"
# === OpenGL Overlay ===
# Note: When OpenGL Overlay is enabled, Video Overlay
# will be disabled automatically
Option "OpenGLOverlay" "off"
# === Use internal AGP GART support? ===
# If OpenGL acceleration doesn't work, try using "yes" here
# and disable the kernel agpgart driver.
# Option "UseInternalAGPGART" "no"
