I have my oppo 980 hooked up to my pioneer receiver via coax. I have my ps3 hooked up to my receiver via optical. Now, when I play a movie on the ps3 its super nice and loud, movies games everything. when I play movies on my oppo, im finding that I have to crank it up 10 notches higher and it still doesn't have the same effect, especially the sub. There must be something in the oppo settings that needs to be changed. I configured my pioneer so that it knows its being connected via coax. If anyone has any input on this, please let me know. I will try and post what the audio settings I have setup right now tomorrow morning, i didn't change much from the default settings. any help would be great, as its bothering me quite a bit.
