I just purchased and Onkyo HT-S3500. I have DirecTV has my cable provider and the box is connected to my Logitech Google TV via HDMI. I then have HDMI connected from GTV to my receiver which then runs to the TV. At first when I was only HDMI I was not getting 5.1 with DirecTV. I then connected the digital optical to my receiver and I am again getting DD 5.1. Today for the first time I tried the You Tube app, and I am surprised to not have DD 5.1? No surround sound or bass? Anyone have an ideas? 1) Why do I not get DD5.1 thru HDMI? 2) Why do I not get DD5.1 on the below apps? ~ You Tube ~ Play Music ~ Podcast I do get DD5.1 with Netflix and PLEX.
