Does the 722K broadcast sound out of all the audio outputs while the HDMI output is being used. Trying to help my uncle out; He has his TV hooked up to the box using the HDMI output on the box and has a soundbar(both recent purchases). He has speakers outside that are hooked up to a receiver and would like to use the DVR as his source for the music outside(DISH music channels). While he has his TV hooked up using HDMI, does audio also broadcast on the analog and/or optical port as well? He just wants to be able to tune to the channel, put hit receiver on, then turn the TV off and just listen to music outside. Thanx in advance for the help!!!
