Help with S500BT surround sound
Just recently finished a 5.1 system with the AVR-S500BT receiver. I've been fairly disappointed with the sound so far.
I use the Xbox One for most of my media, so this may be an issue with the Xbox. The Xbox offers sound outputs of Stereo, 5.1, 7.1, and Bitstream (Dolby or DTS).
If I run 5.1, the receiver offers no Dolby processing channels. The best option is Multichannel In, but this utilizes my surrounds very little, giving me closer to a 3.1 sound field.
If I run Bitstream Dolby, I have access to PLII Cinema, PLII Music, PLII Game, Pro Logic, and Direct. The best choice I've found so far is PLII Music, which allows me to change my Surround Parameters. I've enabled "panorama" and changed "dimensions" to 0 which has significantly increased the use of my surround speakers, but noticeably reduced the overall quality of my sound (I think PLII is a 2-channel format isn't it?).
Is there anything I can do to improve my overall sound? Is this an issue with the Xbox, receiver, or both?
I ordered a mini DisplayPort cable to test running audio through my Surface Pro 3 to use as a HTPC. I'm also considering ordering a Chromecast or Amazon Fire Stick in hopes that they offer better Dolby processing formats. Any thoughts on that?
