Nope, unfortunately not. It's by HDMI design, the audio signal is mixed into
the vertical and horizontal blank periods of the video signal -> so if you
don't have a video signal you don't have audio also.
As a workaround you could try to setup a second X server or framebuffer or
something like that (kms console?) on the HDMI output to just get a video
signal on it.
