Common problem, with probably no solution.  The TV itself only has two
speakers, so it reports two channels as the maximum it can handle.  HDMI
will not transmit more audio channels than the device it is attached to can
handle...  At least that was the situation when I looked into a similar
problem a couple of years ago.
