Question about Sony STR-DE915
The audio plays through one speaker and the connections are fine. I've noticed that walking around it in certain spots changes the quality of the audio.

Love your screen name.
You didn't say what, if anything, preceded the appearance of the problem. There might be a clue.
Can you describe the distortion? Is it excessively bassy? If so, is it happening on all sources?
I'm assuming this is a modern digital receiver that is capable of many soundfield simulations as well as native Dolby Digital, DTS, multi-channel. If so we can use a stereo source and through simulation redirect some of it to the center speaker.
Using one of your receiver's many multi-channel simulation modes, put in a CD or tune an FM station and use it to diagnose the problem during later steps.
If it's only a single source and that source uses individual analog channel RCA cables, swap in another one or temporarily move the Center Channel feed to one of the other channels to see if it's before the receiver (in the source).or inside the receiver.
For multiple sources:
Is your Center speaker defined properly as Large or Small in the receiver's setup menu?The size refers mostly to the bass-handling capacities of all your speakers rather than their physical size. Speakers designated as 'Small' will not be sent much in the way of bass because they can't handle it well. The LFE/subwoofer channel(s) will get all the bass that was intended for them instead.
If you have a Small speaker improperly defined as Large it may be getting bass that it can't handle and that might sound like distortion. Having a Large speaker defiend as Small would result in less bass than expected but otherwise 'clean' sound.
Check the speaker setup in the menu for excessive volume level relative to the others. There is usually a calibration procedure the receiver will use to help you adjust the subjective voume of each speaker using white noise or tones.
Hope this helps.

You might have bad solder connections where the speaker terminals attach to the circuit board inside the case. Mounting screws inside holding circuit boards in place may also have become loose. Often there are ground connections that depend on these screws being tight.
You may also want to check your speaker wires. The wire may be making a poor connection at the terminal. Try cutting a couple of inches off the end, stripping the wire and reconnecting.
Hope this helps. Thanks for using Fixya!
