The output matches the fglrx settings, short of the port_id. As the latter is not standardized, leave it out for now. Corresponding alsa code is already in place. Signed-off-by: Stefan Brüns --- The fglrx register settings where retrieved using Rafal Mileckis gdb script. After applying the patch fglrx and radeon register settings for sink info match, short of the port_id.
