Oh no, that wasn't related to this problem, that was just the fault of my record player somehow. Just expressing exasperation that my electronics seem to hate me lol

Well I've tested it on two different receivers, so I guess it has to be the speakers? I'm just confused as to how I'd be seeing the same problem across six different speakers of various types.

So does anyone have any other ideas or am I SOL?

And now my receiver is playing everything at normal speed, but at a slightly higher pitch. This is a nightmare world Yea, receiver RCA out, RCA to Aux converter, into sound card via aux. I tried just going RCA to RCA but it made it so I could only listen to music, wouldn't pick up dialogue or...

Hadn't tried that. But actually plugging them into the "phone" jack in the front I get good sound out of them. So now I'm very confused?

Yeah, first thing I did with this new one was **** with all those settings lol. Nothing :(

I guess, but then again the last receiver I had was a pretty basic Onkyo that didn't have any of these features. I have played around with the loudness/midnight feature, all the different EQ options it has, made sure dialog enhancement was off, etc. Nothing major really changes, unfortunately.

It happens playing from my pc and from my record player, so yes. What about the speakers? It just seems odd that all 4 speakers would fail in the same way at the same time, if that's what you mean.

As the title suggests, anything that I play out of my speakers from my pc has gone from average sounding, to everything sounding like 128kb/s audio, really really awful. Just happened one day. My setup currently: EVGA Z270 Stinger mobo Sound Blaster X-Fi Surround 5.1 Pro external sound card...
