Question regarding my Onkyo TXSR806 receiver setup

[Nicole]

Hello all...

I am new to this website and I did some search and it is overwhelming what you can find (nice to see so many people write in here though). So please forgive me if this was discussed before and I didn't find it
Anyway, I had a friend do the setup of all my audio and video equipment and it was working fine until now (and he doesn't live close anymore so unfortunately I am on my own). Whenever I used to play a blu-ray movie my Onkyo receiver would just switch to the selected audio automatically. e.g. if I selected 7.1 dts hd in the movie, it would be displayed on the Onkyo display. Now it only shows 'all channel stereo' or whatever you manually select. It won't switch and display to the audio format that I select in the movie. Any suggestion on what settings I need to change to get this to work they way it used to?
Any help would be appreciated
Thanks

Nicole
