WDTV Live Audio Problems

I’ve just updated firmware to 1.03.49_V and while it updated without any errors, my WDTV Live device has no more audio through HDMI. Just before the update everything was working for the last 11 months without any issues. I plugged the composite cables in at the sound plays, but no matter which settings I change the HDMI audio will not work. Absolutly no sound from any setting, any source. 

Is there a way to install the older firmware 1.02.xx? Anybody had the same issue when upgrading to the newest firmware?
