There are problems with HDMI devices:

Content Protection) support can delay
the time taken for a TV to display content

switching the source from one device to
another and back again.
If there are intermittent sound •
disruptions, check that output settings
from the HDMI device are correct.
If you use an HDMI-to-DVI adapter •
or HDMI to DVI cable, check that an
additional audio cable is connected to
AUDIO L/R or AUDIO IN (mini-jack
only).
