The "status bits" and "category code" only matters if you want to use
AC3 or DTS pass through, and most modern receivers seems to simply
ignore them.

Mhm, as far as i know nobody have testet HDMI audio on the RS780 before.
So i think there is just something missing in the implementation, but
since you have a working fglrx setup it should be possible to fix this.

To track down the problem i would suggest to look at the differences in
how fglrx and radeonhd programs the HDMI registers. This has worked
quite well in the past.

Compile the rhd_dump utility in the utility/contest directory of the
radeonhd driver, then make dumps of the 0x7000-0x8000 register range:

sudo ./rhd_dump -r 7000,8000 1:00.0 > dump.log

Once with fglrx and once with radeonhd, while audio is playing.
(Where 1:00.0 is the pci-id of your graphics card, NOT of the audio
codec).

Send me the resulting files and i will take a look at it, and see what i
can do.

Bye,
Christian.
