HDMI EDID Audio problem
My setup is ION2<---HDMI--->Marantz SR5002<---HDMI--->Samsung TV.
For reasons I won't go into, to get video out in this setup I've stored the Samsung EDID in a file and reference this in xorg.conf; this gives me video + 2-channel sound. The SR5002 supports 7.1 sound so I need to either 'edit' the Samsung EDID to change from 2-channel to 7.1-channel or something else. Any ideas how this can be achieved? Note due to the setup I can't not use the Samsung EDID since this results in no video at all. The real setup is:
....................................|Marantz SR5002<---HDMI Out--->Samsung TV
I'm using 2 of the SR5002 HDMI inputs; only HDMI3 returns the correct audio/video EDID
