Audio Crackling (fuzzy, poping, crackling sound)

Audio Crackling (fuzzy, poping, crackling sound)

Sure could use some help here...

 

I am getting an occasional crackling sound (kind of sounds like the tweeters are blown on my speakers) coming from my center, left, and right channel speakers.  Lately (after the HD UI update) it has become more noticeable. 

 

This typically occurs when I am watching movies or programs in HD right when the action picks up.  Its even more noticeable when there is a scene with a lot of bass, like an explosion or crashing sound.  It almost makes me think that the DirecTV receiver is trying to convince my speakers that they should be playing bass frequencies through the tweeters. 

 

I have two home theater setups in my house.  One with a plasma TV and a high end Marantz receiver with new Polk speakers and the other in my basement with a projector, B&W speakers and another high end Marantz receiver.  Upstairs has a HR23-700 receiver, and downstairs I have a HR22-100 receiver.

 

This problem occurs on both setups.  I have even recorded shows where I have noticed the sound to see if it is there during play back.  This method makes it easy to reproduce the crackling by replaying the same section of video in either room with both setups.  My only common factor, other than DirecTV, is the Marantz receivers so I bypassed my upstairs receiver and played the sound through my TV speakers and again the crackling was there at the exact same spot it was when I heard it originally.

 

I have also done a lot of testing on both setups using a dedicated BluRay player and a PS3.  Both of those provide crystal clear audio without any distortion, crackling, or pooping.

 

Going even one step further I am also able to reproduce this when I play back the video I recorded using the DirecTV2PC feature.  I attached a audio clip from my PC playing this back so you can hear what the crackling sounds like.

 

Since I am hearing this on two different receivers, and on my PC via DirecTV2PC I have to assume that my recorders are recording the audio this way so it is either a box issue, software issue, or I guess it could be my signal coming in but it seems odd that it would only manifest during HD programming.

 

If anyone has any suggestions it would be greatly appreciated.  I have a lot of money invested in my home theaters but with the quality of the service being provided by DirecTV and there receivers I might have been better off with the $99 Theater In A Box special of the week Frown

Re: Audio Crackling (fuzzy, poping, crackling sound)

how are those DirecTV receivers connected to your A/V surround receivers?

Re: Audio Crackling (fuzzy, poping, crackling sound)

My living room setup has the DirecTV box connected to my plasma TV with a 1.3 HDMI cable, then from my TV to my receiver via another 1.3 HDMI cable.

 

My basement goes directly from the DirecTV box to my home theater receiver, also with a HDMI 1.3 cable.

Re: Audio Crackling (fuzzy, poping, crackling sound)

Let's discuss connections.  In order to get the Dolby effects, the conncetion must run from Directv receiver to AVR and thence to the TV or projector.  Why?  Because the TV is almost surely not capable of feeding a full Dolby signal in via HDMI and out via the digital output port.

 

Your living room setup, if you wish to leave it that way, should have the Directv box set to Dolby off.

 

As to the source of the "crackle".  Is the coax from the dish passing through a ground block and is that ground block bonded to your homes service ground?

We have the exact same problem.  Did you ever get it resolved?  This just started over the last month or so.  Very strange.

Re: Audio Crackling (fuzzy, poping, crackling sound)

I verified all my wiring, and the I made sure that I isolated the ground for my ground block to a dedicated ground rod separate from the home service ground.  I also spent time making sure my Direct receiver was plugged directly into my AVR.  None of this seems to have made a difference and the issue is still there. 

 

Since I'm seeing it on all 3 boxes (2 HD DVR's and 1 HD without DVR) with 3 different TV's I'm pretty sure the TV and AVR settings have nothing to do with it.  Is it possible that I'm having problems with the SWM?

Re: Audio Crackling (fuzzy, poping, crackling sound)

I'm not aware of any way that your satellite signal reception could cause these sorts of "audio popping/crackling" issues.  It's much more likely that you have something goofy with your home's electrical wiring ... perhaps an intermittent ground connection somewhere.  Tracking down the source of the problem may be very difficult.  How old is your home's electrical wiring?

Just for grins ....

 

Please post back with your signal readings for each satellite's transponders (and both tuners if applicable).  You'll find these readings under "Menu" -> "Setup" -> "System Setup" -> Satellite -> "View Signal Strength".  Note the "+" and "-" symbols next to the "Satellite" and "Tuner" entries where you can toggle the readings between the various satellites and both DVR tuners. 

 

Fill in your readings for each satellite and tuner using these examples.  A properly aligned dish will show 80-90s on most of the relevant transponders (although some will be low or zero):

Wiring is only 10 years old.  Zero issues when watching a bluray.  Happens on both HD DVRs.

Best to start your own new thread using the "Create New Post" button on the main forum page.  Your problem may very well be different from the original poster's.    With a new thread you can provide more information about your equipment, location, and troubleshooting you've tried so far.  And this forum software makes it difficult to track or respond to folks that add onto someone else's thread.

Re: Audio Crackling (fuzzy, poping, crackling sound)

I also do not believe that it has anything to do with my satellite reception.  But, it is definitely being caused by my DirecTV equipment since that is the only source in my house causing the problem.  Blu Ray, PS3, DVD, etc. all work fine.  The crackling only comes from the DirecTV output.  Either the boxes are not decoding the signals correctly, or something is being injected into the boxes from the SWM.  

 

If there is anything wrong with my house wiring then why is it that I only see problems with DirecTV equipment.  Everything else in my home works fine.  Is it possible that the DirecTV boxes are not equipped with the required filtering necessary to accommodate various home wiring noise?

If you post your signal readings as previously requested we can rule out that possibility. 

 

Your problem is quite rare.  If it's not reception related then it's almost certainly a house wiring/grounding issue.

Re: Audio Crackling (fuzzy, poping, crackling sound)

This is happening on my 2 month old surround setup. Pardigm 100's, c650 center, sub 15 and studio 10's for surround. These are being driven by a Marantz AV7005 and an MM7055 AMP. This is definitely the DVR or the transmission itself. The distortion is apparent through the DVR hooked directly into the TV at the exact same points during a film. Men In Black has a good amount of this crackling going on. This is not a rare thing. I've also noticed that this HR24 in my main setup has been a little laggy and not as responsive as it was a few months back. After the last UI upgrade hmmm perhaps…… Any word on what is going on? I am so bothered by this that I may bring Time Warner into the mix to test over a month's period. If this is not apparent on Time Warner then my 10 year stint with DTV may be at an end. Thanks….
