Your machine have two HD-audio controllers, one for on-board audio and another for HDMI. HDMI looks like ATI D-GPU, and this confuses the system when GPU isn't active. It seems that HDMI controller doesn't respond when GPU is disabled. A question is whether HDMI really works when D-GPU is enabled. Did you test it?
