I use my XBOX1X for gaming as well as YouTube Live TV. The past week my center channel hasn't been making sound. I know the connection is fine, as I can put it in 7 channel stereo and it works. When it is in "straight" mode it says its in sur decode, but no sound produced. It does it on Call of Duty 4 as well as YouTube TV. I know not all TV formats are in surround, but at least pro logic?
My XBOX audio settings are set at surround. My Yamaha has the settings as 3.1.
Any ideas to the problem? Thanks for any information given to shed light on the issue.
Hey, I know this is real late, but hopefully it will help other users in the future. I've got an RX-A740 and an Xbox One S, but it should be the same.
If you're playing an older game that only advertises "Dolby Pro Logic II" support, or watching older media that had "Dolby Surround" audio that only ever got a consumer release in stereo, you need to (temporarily) change your Xbox or other device's output settings to stereo
I know it sounds counter intuitive, but it's not. At least not entirely. This receiver and I'm guessing a bunch of others don't allow you to decode matrixed surround (Dolby Surround, PL, PLII, for the most part, Dolby Digital EX and DTS:ES in some cases, more on that later) if they're detecting 5.1 or 7.1 input. And rightfully so, why would you need to use a decoder designed to recover a matrixed surround mix from stereo audio on what is clearly
already surround audio!
And that's the catch, your Xbox doesn't know any better, you set it to 5.1 or 7.1, it reports that to the software, and then you get surround! Except when the software always outputs stereo audio, then you don't. So whether it's an older or BC game that didn't shell out for a Dolby Digital license on a different console, or you're watching anything that isn't a Blu-Ray disc, you need to "trick" your AVR and source device. Use Stereo audio, then when you pick "SUR. DECODE" you'll be able to select "Dolby Pro Logic II Game"
The only other device I've encountered where that's a huge pain in the ass is the Wii U. It's got an HDMI port, it supports 5.1 LPCM output...and usually just outputs 2 channels worth of audio, with the center, surrounds, and LFE signals being silent. Lame. "7ch stereo" will still work in these cases, but if the game or media has a matrixed mix, then I want it damn it.
Regarding DD-EX and DTS:ES, they work
but only in a bitstream/passthrough scenario. Depending on how they're being decoded, especially if whatever is doing it is always outputting 7.1 LPCM, like the Xbox, you might end up with 1-2 channels of silence. No easy way around that one other than using a different device.
