Might depend on TV and/or libcec. My Samsung is the same while my Panasonic works all the time.
The following might work (very possible):

Code:

/opt/vc/bin/tvservice -d ~/edid.dat
sudo cp ~/edid.dat /boot

and add the following to config.txt (preferably via Raspbmc settings):

Code:

hdmi_edid_file=1
hdmi_force_hotplug=1

Reboot.

Edit: You need to be directly connected to the TV for the above to work (TV on of course).

Thanks that did the trick.
