I have been investigating a little this problem and it looks like the problem is caused by using static dfp1.edid (edid dump) under etc/ati. If there is a normal handshake the sound is never lost and also the line (xrandr -display :0 --output DFP1 --off; xrandr -display :0 --output DFP1 --auto) is not needed.
But i would prefer the static line to edid dump if it would work. On nvidia i did not see those problems. I have also experiment with many edid dumps and on all the behaviour with loosing the sound was the same.
And command (dmesg | grep -i hdmi | tail -n 10) has always report the same info no matter if the tv was on or off and the sound was lost.
