How do i eliminate this static?

[markw]

Absolutely!

If the cables are long, unshielded, and tied to all your other cables, then you likely just found your problem!

Take the cables that run the signal from the TV to the speakers out of that bundle of cables! Temporarily connect them and run them as far away from other cables as possible. Does the problem go away? If it does, then put it back in with those bundle and see if the problem comes back. Problem solved!

In particular, is there a POWER CORD (you know, a cable that plugs into the wall for power) running parallel to your signal cable?

I had a similar problem on a phono signal cable. For me, I swapped to a high quality shielded cable and it fixed my problem.

I would think that if this were the case, the noise would appear on both channels.

Agreed, but you never know. It's easy enough and free to isolate the signal cable and see if that solves it or not.

If not, then that's another possibility off the list.

It still seems to be persistent, however it does not make the noise when playing the audio through the television itself. It also does not make the noise when the ps4 is off. Only when the ps4 is on, and when I have it coming out through the speaker system.

It's something internal to the PS4. Heaven knows what.

I just tested it with another device on the same tv and system. It does it on another device also. I hooked up my friends Xbox one to my television in the same way I hook up the PlayStation, and it does the same type of static. I'm almost positive it did not have anything to do with the PlayStation, because I've had this setup for about a year and a half with no issues like this. This just started recently. Is it possible it could be related to the power strip or wall socket that everything is plugged into?

Now is the time to remove every possible problem area. ...one at a time.

that's how you isolate the problem. Guessing is useless.

I have reviewed this thread at length. It is clear to me that the DAC in the TV has failed.

He needs to have the TV fixed, replaced or not route digital audio though his TV.

I would assume if it were the TV's DAC, I would think all audio would be kerfutzed but that post seems to say that ain't so. It seems the internal speakers are fine.

I'm pretty sure it is the TV. The problem is likely on the HDMI board or HDMI DAC interface. With what he has posted there is a problem decoding audio from an HDMI source when a device is connected via HDMI. Since the noise occurs when I device is connected to an HDMI connector, I suspect something has happened to one of the grounds.

On researching this I find that there are a number of grounds in an HDMI cable and plug.

Audio is carried on TMDS channels 1 and 2, and video on channel zero. Now these are carried as twisted balanced pairs in the cable.

As you can see all three TMDS channels have their own grounds, as to DDC/CEC and the TMDS clock.

I have further found that anything that unbalances these twisted pairs is likely to result in static.

I suspect that most likely TMDS channel 1 or 2 grounds are interrupted somewhere, most likely on the HDMI board itself.

So I would like to know how many HDMI ports this TV has and if more than one, if they all have the problem. If there is only one HDMI port on the TV, then the ground interruption is most likely where the port attaches to the board. If there are multiple ports and they all do it, then the interruption is somewhere on the board.

For the record (I don't think anyone has said this in this thread yet), the way that the OP is trying to connect up his speakers is probably THE WORST POSSIBLE WAY.

There is a reason that few people on this site would attempt to hook up their speakers/TV in that manner, and now the OP is learning why for himself.

It CAN be done that way, but it is far from ideal and similar problems are not a surprise by any means.

I agree with everything you say here. However it used to work and now does not. So a fault has developed and form the posts here it is in the HDMI/DAC system of the TV.

As I have often said in the HT arena, you should regard the TV as the equivalent in video to a speakers in audio.

In our world a TV needs a power cord and one HDMI lead. After set up the only button you ever need on the remote is the on/off button. That is the way to have a relatively trouble free existence in the AV world.

Aaaaaaaand, buy the $10 Optical to Analog adapter already and circumvent the television's audio entirely.

Am I talking to a brick wall?

I'm guessing based on the speakers OP is using (which I asked for details on and never got) and the TV (which I asked for details on and never got), that spending much money is a non-option.

UNLESS, OP is trolling. In that case I have no sympathy at all.

As I said he needs to not send audio though his TV.

OP has been sparse on the details of his set up. If he is using his TV as a selector switch among other things, he may have a problem.

The other issue is that with those type of arrangements the video and voice can get hopelessly out of synchronization from digital delay.

 

[Seth=L]

As I said he needs to not send audio though his TV.

Right, so he can use the $10 optical/analog device to connect straight to the PS4. He would have to to set the PS4 to PCM at the following bitrates - 44.1, 48 and 96 KHz.

At this point, I agree that this would be a good option to try out and see if it solves the problem.

Yes, of course he can do that, but the chance of the digital delay between video and audio being the same are remote, but he could get lucky.

I bet he won't notice/care.

Right, but if I can pay $10 and then have very high confidence that I have finally identified a lingering problem, then that is $10 well spent.

So, even if he is not 100% satisfied with that setup as the end resolution (and he might be satisfied anyway), at least he has more info leading to the root of the problem.

Sorry for the late reply, I was at work. Something interesting I have noticed, I have plugged the external speakers into a separate wall socket, and now have not noticed the issue reemerge. As much as that makes no sense... So far it has not done anything. Seth for that device you mentioned and linked to Amazon, is there a store that sells them? Somewhere I can just pick one up today? Or is it something that must be ordered? If it is something that can be picked up, do stores ridiculously overcharge for an adapter like that?

You are saying that the ONLY thing you changed is the power outlet where you plugged in the speakers? ALL other connections are exactly the same? And the problem went away completely?
