Hi

When I created new images for my PCPs for 7, I was reminded of an HDMI
problem, which is perhaps more relevant now with the different handling
of HDMI in the new kernel.

If you're using HDMI output, not all devices show as connected if the
display or amp isn't on, or isn't switched to the correct input.  In the
old kernel, Squeezelite would still start, but not output video to the
HDMI port.  Now, with the seperation of HDMI and headphone, if you
select HDMI output, but don't have that display turned on when you do
it, Squeezelite won't start because the HDMI devices aren't available.

To make this work reliably, you need to add


Code:
--------------------
    hdmi_force_hotplug=1
  hdmi_drive=2
--------------------


to config.txt.  hdmi_force_hotplug=1 sets the pi to use HDMI mode even
if no HDMI monitor is detected. hdmi_drive=2 sets the pi to normal HDMI
mode (Sound will be sent if supported and enabled). Without this line,
the pi would switch to DVI (with no audio) mode by default.

I wonder if it's worth adding a "Force HDMI Output" tweak to the tweaks
page to write this to config.txt
