As long as register 0x0534 isn't changed that shouldn't hurt bit. > > I don't know meaning of > R600_AUDIO_SUPPORTED_SIZE_RATE (0x7394) > is this something important? No, that register only tells alsa which sampling rates and bits per sample are supported. As long as you don't want to use 24bit audio or sampling rates other than 48000 Hz we don't need to change a bit. > It reminds me RV770 issue from radeonhd, where we don't get working > audio. All registers are 100% alright, but no sound. Your script is missing something, the 0x7400, 0x7700 and 0x7800 are only bases. Try comparing the whole 0x7400-0x74ff, 0x7700-0x77ff and 0x7800-0x78ff ranges. For the RV770 i have the strong feeling that ATI have started to double buffer the HDMI registers, and there is a bit somewhere that tells the hardware to start using the new values on the next vertical or horizontal retrace. > Maybe order of setting registers matters? Do we set registers in > different order than radeonhd does? There are registers in the 0x7304-0x7340 range that can deadlock the audio codec if not written in the right order (i think they are for interrupt and dma control), but i really avoid touching those, the bios sets them up on boot pretty fine. > Please, check attached log files.

Yeah that's another point that could go wrong. At the moment i enable hdmi on any digital interface i can find, even if it's an LVDS, the worst thing that could happen is that you don't get a picture on your panel.
