Sound from speakers sounds "low quality"
« on: Sat, 23 December 2017, 00:02:53 »
Recently, anything I play on my speakers through my receiver just sounds like I'm listening to 128kb/s music, everything just sounds fuzzy and awful. I've used different receivers, sound cards, component to aux cables, inputs (computer and record player), and have even changed motherboards since the problem started to occur. Two of my four speakers run through my subwoofer, but since not all the speakers are, it's obviously not a problem with the sub. I really have no idea what it could be at this point.

Check the speaker wires and connections first, since that is the easiest fix. Wires can get frayed or worn where they bend.

Otherwise, probably something like a blown capacitor. How old is the system and /or how much use and abuse has it seen?
The Article II clause gave readers some guidance by giving two specific examples of impeachable misconduct: “Treason” and “Bribery”. Both were “high” offenses indeed.
”Treason” – defined elsewhere in the Constitution – meant waging war against America or betraying her to an enemy power. “Bribery” – secretly bending laws to favor the rich and powerful – involved official misconduct of a highly malignant sort, threatening the very soul of a democratic republic committed to equality under law. In the case of a president who did not take bribes but gave them – in effect paying men to vote for him – the bribery would undermine the very legitimacy of the election that brought him to office.

Speaker wire all looks fine, everything it in right. The problem is it's on every speaker and sounds exactly the same, making me think it's before that. The strange thing is that outside of the speakers, every single part of my setup has changed at some point since the problem has started. The receiver is actually pretty newish and in very good condition. The motherboard is totally new, the sound card that I'm using has barely been touched.

Seems unlikely, but could the subwoofer somehow be affecting the sound coming out of all the speakers, even those that aren't run through it? It's really the only idea I have at this point.

I know more about traditional stereo gear than I do about computer sound.

There are certainly parts of crossovers and filters that could fail. In the old days the amplifier made all the power and crossovers blocked given bands that their corresponding speakers didn't like. That was the messy and inefficient way to do it.

If your subwoofer is self-powered, as almost all of them are today, then it should be getting a line level signal of just what it needs to reproduce. If you are sending it speaker level signals, which it has to attenuate and then amplify back up, and especially if you are sending it a full-spectrum signal that it also has to low-pass select, then it could conceivably produce distortion elsewhere.

But if the rig was working properly at one time, but now it isn't, then clearly a piece has failed somewhere.

so since you say u have swapped out a bunch of equipment? .. a couple ideas / things to check..

for the most part if it is music you are listening to you'll want to do that in stereo rather than surround modes..

If you haven't tried different speakers .. how old are the speakers?  have  you checked the surrounds (the black(generally) rubber / felt..material on the outside edge of the cones for wear/ holes/ deterioration?    Also if the speakers are old the crossovers could also need work perhaps...

have you tried playing the music say with your smart phone and this receiver setup?  how does it sound vs the pc as the source?

check windows sound control panel settings::  Sound> device > configure (if not greyed out) select stereo (at least to test..if you want to go back to surround then change it later) test > next  > check full-range speakers front left and right.  confirm and go back to control panel and select audio device> properties  (disable enhancements) / advanced tap select desired default bit depth.. try 24/ 48000 (especially if it is set to a 16/ xxxxxx currently)  / turn spatial sound off if it is on.

oh right select supported formats check those that apply (test if unsure)..


then try again... what are the source files / player software??

Ah yeah, I see that that's what I was using on my old receiver (switched back, hate the one I just picked up for multipurpose stuff).

If you haven't tried different speakers .. how old are the speakers?  have  you checked the surrounds (the black(generally) rubber / felt..material on the outside edge of the cones for wear/ holes/ deterioration?    Also if the speakers are old the crossovers could also need work perhaps...
So I have 3 different sets of receivers. My two fronts are Infinity RS 125s (not super old, ealry 90s I think?), the side/surrounds are Missions, again not that old. I also have a pair of Onkyos that came with the receiver that I have tried and still gotten the same sound. Would there be some sort of problem where a single bad speaker could ruin the whole thing?

have you tried playing the music say with your smart phone and this receiver setup?  how does it sound vs the pc as the source?
Tried with phone, sounds the same

check windows sound control panel settings::  Sound> device > configure (if not greyed out) select stereo (at least to test..if you want to go back to surround then change it later) test > next  > check full-range speakers front left and right.  confirm and go back to control panel and select audio device> properties  (disable enhancements) / advanced tap select desired default bit depth.. try 24/ 48000 (especially if it is set to a 16/ xxxxxx currently)  / turn spatial sound off if it is on.
Yep, had all that except surround instead of stereo, changed that.

oh right select supported formats check those that apply (test if unsure)..
don't see that

then try again... what are the source files / player software??
Spotify, youtube, foobar all sound bad. Spotify with their extreme quality downloads and foobars with FLACs

ok weird... the supported formats tab isn't always present if it isn't don't worry about that btw.


if you turn the stereo on with nothing playing are do you hear a fair bit of hiss /static (ground loop)?? turn on stereo with nothing playing and turn volume up a bit say 10'oclock is there background hiss / noise??


have you listen to other stereos that sound better to you lately???   (maybe get hearing tested?)

I think if it was me... I'd try disconnecting most of the speakers and try the infinity's and mission's separately (stereo ... no sub)  and see how that sounds..

one bad speaker/ broken~ish speaker could make everything sound off..but u could probably trace it down just listen to them close up on at a time...

If I crank it pretty high, yeah I get some background static-y/fuzzy noise.

Trust me, I take good care of my hearing lol. Interesting idea though

Yeah, I guess I'll just try them all one by one.

So still having this problem, might head to a stereo place or something I guess. But one last shot here? Just to reiterate, everything just sounds like low bitrate sound (i.e. awful). I have changed literally every single component of the setup at some point (motherboard, sound card, receiver, speakers, speaker wire, routed speakers through subwoofer/routed directly to receiver, used different component to aux cables, played from PC and turntable in different inputs to the receiver). I've changed some settings on the computer itself, but any other suggestions on that front might be the most fruitfull. At this point, I have literally no idea what it could be

if you plug headphones into the pc and it sounds fine, it should be the pc.

if it's the digital out of the pc, then plug that directly into your tv and tell it to use hdmi sound.

I doubt it's the pc.

prob receiver broken.

Just tried moving everything but the PC to a different power bar and nothin. I wouldn't have to move the PC, would I?

Well my headphones run through a DAC so I probably wouldn't be able to tell anyway. But if it's a broken receiver than I guess I just got two broken receivers that sound the same?

Can you isolate the receiver, and connect only 2 speakers to it and plug it into the wall - nothing else?

Tune it to the radio and see if that still sounds bad. If so, connect it to a turntable and play a record only to verify that the radio tuner section itself is not bad.

Last, repeat both steps above using headphones but not speakers to verify whether the speaker outputs and/or the preamp section are good or bad.

If you isolate each component one at a time and verify which is good (including speakers and headphones) then you will have something to work with.

If any of those stand-alone audio permutations produces a clean sound, then you have a base line and can zero in on a problem area.

If the audio components successfully produce a good sound on their own, then you know that your problem is in the computer.
The Article II clause gave readers some guidance by giving two specific examples of impeachable misconduct: “Treason” and “Bribery”. Both were “high” offenses indeed.
”Treason” – defined elsewhere in the Constitution – meant waging war against America or betraying her to an enemy power. “Bribery” – secretly bending laws to favor the rich and powerful – involved official misconduct of a highly malignant sort, threatening the very soul of a democratic republic committed to equality under law. In the case of a president who did not take bribes but gave them – in effect paying men to vote for him – the bribery would undermine the very legitimacy of the election that brought him to office.

So I can't get the tuner to work, probably that I'm missing an antenna that it looks like there's a spot for in the back. But having just the turntable connected, two speakers direct into the receiver, and the receiver directly into the wall still yields bad sound.

But, headphones plugged into the receiver sounds fine. Is it possible that the component connections in the back are all corroded on both receivers?

Just connecting a couple of feet of wire to the common/ground and 75/300 ohm screws should be enough to find some shard of a radio signal.

But if the headphones are OK then that means that the preamp/controls sub-system is good while the bad speakers indicate that the main/power amp is bad.
 
PS - unless it indicates that the speakers themselves are bad

Well I just tried the other receiver again for ****s and giggles with the minimal setup and it sounds just the same as the other receiver, so I'm still just as confused. I've also used like three different sets of receivers bought at different times so it's not that.

Could it be that all my speaker wire is total **** somehow?

Sure, anything can go bad. You are certain that your speakers are good, aren't you? That is the first thing to go bad.

The cones and surrounds are soft and can deteriorate or suffer damage.

I could try them somewhere else I guess, I just figured it was unlikely that 6 individual speakers all went the same level of bad at the same time. I guess I'll try some new wire?

If headphones sound right then that locates the problem downstream from the preamp stage.

You problem will surely be failed components or failed connections somewhere along the line. Capacitors in the main amplifier stage are usually a good place to start.

Re: Sound from speakers sounds "low quality"

Even though it seems unlikely 3 pairs of speakers fail at the same time don’t rule it out. All it needs is for them to have been well overdriven once by accident and the tweeters are blown, or the perishing surrounds break up.  Could have at one time dis/reconnect the amp’s input and the transient caused damage.  I’m just giving some examples of what can happen that we don’t know about and may have happened that you may not have been aware of at the time as well.

You have changed the source (mobo), rca lead??, amps but not the speakers.
You have removed the pc and used a turntable with the same speakers to get the degraded sound.
Used the turntable, same amp with headphones to get a clean sound so you know the source and preamp are good.  This leaves the power amp, speaker cables and speakers.
Beg/borrow/steal someone’s speakers and cables to test on your amp.  Or even better, take your speakers and cabling to someone else’s place to test on their set up.

I know jack about audio setups but if it sounds crappy/weak I would think it would be something to do with the amplifier (since you're using a receiver the amp is built in).
