DDMA enables Radeon™HD 7700-7900 Series GPUs with the ability to output multiple and independent audio streams simultaneously through digital interfaces that support audio, such as DisplayPort and HDMI®. Each audio stream can be multi-channel (up to 8 channels)
AFAIK yes, the multi-hdmi-device AMD cards are "DDMA".

Alex, do you have information regarding why "Presence detect" (aka monitor_present above) seems to be set for all HDMI pins in the response of Pin Sense 0xF09 verb (or if it is even expected), and/or if we should use alternate means of getting jack status?
CONFIG_SND_DEBUG_VERBOSE log might also be interesting, I wonder if eld_valid is also 1 for every pin or not (before ALSA forces 0). Also, I wonder if all monitor_present fields are 1 with fglrx driver as well, or when all displays are unplugged...

The GPU driver needs to set the status properly when the monitor is connected/disconnected. At the moment the GPU driver calls the audio_enable(true) once at driver load time, but it should call it at runtime when a monitor is connected (true) or disconnected (false). If I have time this week I'll see if I can whip up a patch to test.
