What is the reason that the audio cuts out momentarily ? This is very annoying and does it on most of the channels. It is random but consistant, usually cuts out one or two words ,enough to miss what is being said.
This is same issue I had 5 years ago when first using Comcast, Went over to Fios for a few years and never had the problem. Recently got back with Comcast and problem still exists. I know it is not my cables in my house since it was perfect sound always with Verizon Fios. If Comcast has no fix for this, then back to Fios I will be going.......does anyone else have this same problem and IS there a fix?
Solved! Go to Solution.

I hope to see an answer. I have been struggling with this for a year. Comcast says they will monitor and fix. I Finally convinced them it was outside of my house. My comcast repair person will not return phone calls to the number he gave me to call. This is a real mess.
03-21-2011 09:42 AM
Ok thanks, I am going to contact Comcast today to get an answer,sounds like they are not very interested in fixing the problem...........I will go back to Verizon if this continues much longer

I'm having this same issue but mine only started Saturday when I purchased a new TV. On my old RCA tube tv it never did this but on the new HDTV it is doing it. It drives me crazy. I'm not sure its the cable or the new TV. How can I tell for sure before my return 30 days are up?
03-22-2011 09:38 PM
One thing to try to see if it is your television would be to play a DVD and see what the sound does during that.
Also run the cable from the wall, not the cable box, and see how the sound reacts.
Either way you can check out the tv and then decide for yourself on the service.
03-23-2011 10:52 AM
update on this sound issue: comcast is going to send tech out to check for possible problems from where the cable enters my residence to the "nodes" or individual splices near the street..Hopefully they will find a solution.
03-25-2011 06:24 PM
Ok tech came over two days ago ,checked the cable from house to street and into junction box two house away where it ends. Said that someone installed wrong type of cable 6 years ago when housing tract was built, and that it was " indoor cable', not meant to be in the wet /damp underground location that it is in.
So tech thought this was cause of problem and replaced entire cable from house to junction box ( about 100 feet worth) and said to try it and see if it cures problem. It did NOT cure problem, but at least I now have the right cable! Tech told me to call him if problem persists, so I called today and told him and he is going to contact the " maintenance " department on Monday to have them check the cable beyond the point that he hooked the new cable to. So we will see what happens next.....my opinion is that it is an euipment problem at the source(wherever that is?) and they need to fix thier faulty equipment.
The fact that the video never misses a beat and is crystal-clear, tells me that the cable is doing its job all the way from my location to the source. There must be a faulty audio amplifier or wharever they use to send audio signal is acting up.
more to follow next week in this quest for perfection!
03-28-2011 07:55 PM
mine has been doing it but only on shows that we watch on the DVR, not ones we watch "live"-I figured it was something w/ the signal to the box or defective hard drive on the DVR??
03-28-2011 08:09 PM
Has anyone posting audio issues here tried the following if your using HDMI?
With your Comcast remote
Turn off the DVR
Arrow down to "Additional HDMI settings" press select
Try changing the audio output selection from "auto" to "L-PCM" or "passthrough"
and see if either of those selections helps. Press the power on the remote twice to exit the menu.
03-29-2011 04:13 PM
Ok ,I set both of my HD boxes to " L-PCM" . They were both on "auto"
While I was in the menu screen, I noticed that one of my boxes was only set at 480 output, so I put it on 1080 I . Maybe I will get HD now.......it is only a 40 inch LCD but going from 480 to 1080 output from cable box should be better picture I would think.......It looked like hi def but how could it be if the box was set at only 480 output via HDMI?
Anyway now that I have changed the HDMI audio settings, I will wait and see if my sound cut-out problem is still there.
03-29-2011 06:04 PM
Ok Comcast told me they sent the maintenance crew today to work on the problem. They adjusted the
amplifiers in the nodes , according to Comcast . There apparently 3-4 amplifiers in each node. I will
give it 48 hours and see if problem is resolved. They said they are 99% sure this adjustment/alignment of
the equipment will solve the missing audio problem.
More to come................
03-30-2011 06:32 PM
Well it has been a day since I adjusted the DVR HDMI setting from " auto" to " L-PCM
and also the adjustment to the nodes done by Comcast crew. So far problem has gone away but I will give it
two more days to make sure.
Then I will put dvr back to " auto" and see if sound cuts out again. This way I can tell what actually fixed the
problem.......was it the setting change on DVR.....or did Comcast crew fix it by adjusting the nodes?
more to follow.........
03-30-2011 06:41 PM
I have asked for them to do that multiple time without action. Problem is still here and the techs focus on an inside problem which in the end after testing they all say does not exist.
03-31-2011 05:38 PM
Well I would keep calling them until they resolve it.......they get enough money for the cable service so in my
mind it should pretty much work perfectly. I had to call about 7 times before they finally looked into the
problem. I asked to speak with a supervisor and told them to get the sound fixed or they can
come back and take all the equipment back and I will get the dish network or some other cable.....that
seemed to get them motivated.
03-31-2011 05:45 PM
It has been 48 hours since Comcast crew adjusted nodes, amplifiers etc. in the street.
So far my sound has been flawless, no drop- outs or missed words. I will wait another week and watch more
channels just to be sure the problem has really disappeared for good.
So my advice to anyone experiencing the symtom of the sound cutting out for 1-3 seconds, call Comcast
have them come out and check/adjust the nodes and amplifiers in the cable boxes OUTSIDE your home
and even farther down to the next junction or two
this is where the issue is apparently. Unless my problem comes back, this will be my last posting on this
issue. good luck to you all.......
03-31-2011 06:14 PM
my Comcast guy was out today and I showed him the post and he had no clue what it meant! SO mine will still be doing it! He said he will escalate to support and that he was not aware of the problem previously.
04-06-2011 05:46 PM
My sound was cutting out only on HD channels. Tech visit changed wiring from street to house, checked signals, etc. Left without solving the problem, and promised to check with "someone".
While waiting, I changed from optical to coax digital output to my receiver. No change. Still dropping out. I installed RCA analog audio lines from the cable box to my receiver. Didn't hear any dropouts, but sound was worthless. Ugh! Went back to optical cable, but left the RCAs connected. No Dropouts!!
So either, swapping back and forth, optical to coax, somehow cleared up the problem...OR the problem was maybe a ground fault cured by the addition of the RCA cables.
Your guess is as good as mine. Been watching over an hour now and still no dropout on any channel.
05-25-2011 01:16 PM
I'm also having this issue. The techs tried just about everything in the house, including a new box, and still the audio continues to cut out, just as described above; one or two words randomly and consistently.
The box is a DCX3200M, hooked up via HDMI to a projector, and I've tried both coax and optical outs to a Yamaha receiver. It works with RCA inputs to the receiver (obviously not acceptable audio), but no digital audio seems to be getting transmitted correctly. Which is also consistent with the channels that seem to be affected; all HD channels, and some SD channels... The AV setup has worked just fine with DirecTV for the last 2 years, and I've double triple checked all the connections with a Bluray player, which works perfect.
I'm a new customer and have had to take time for techs (who have all been very professional, no problems with them) yesterday for the install, today, and once more on Friday!!! This is getting frustrating...
02-13-2012 06:51 PM
I have this issue too. I have since I replaced my older box for one of the newer Cisco RNG200. Since the issue only came when I got the new box this must be an issue with the box. Saying this issue is closed with the answer of "Call Comcast and have someone come to your house" is both lazy and stupid since apparently many of the Comcast guys that are going out to houses have no idea what to do.
Try again Comcast. This time give it some effort.
03-16-2012 04:43 PM
what do you think cured it in the end? do you think it was really adjusting the nodes, or because you changed the audio setting to PCM? is it still working ok?
did you try changing audio back to Auto to see what happens?
03-18-2012 09:12 AM
It was yhe nodes that were adjusted that finally fixed the problem. When it was happening it would affect all 3 tv s in different rooms with three different cable boxes, and the HD DVR box was the one that i set from pcm to auto and made no difference......i dont even know what it is set to now because the problem was fixed an I get good sound, not once since last March did the audio cut out.
I will tell you if you are having the same issues will will have to be very firm with Comcast, as they will always tell you it is an equipment problem in your house(which may be true in some instances).
But it took three different crews to solve my issue, which was finally resolved after 10 days when the line crews (2 trucks with 4 workers) checked the line from the overhead wires down the street, followedthem into the underground section beneath my street, and finally inspected one of the nodes(which I think is one of those green boxes they have betwwen peoples yards evey 3-5 houses). They made an adjustment in there which most likely was some sort of ampifier to boost the signal and everything is good now.
I dont know why my neighbors did not have the same problem but maybe they did and they ignored it or could live with it.......
Anyway you will need to be determined and keep calling Comcast until they fix it if that is the cause of the problem.
The way i look at it ,we pay them alot of money every month so we should have a clear picture and clear audio.
03-18-2012 01:05 PM
sounds like yours was a different issue. Mine seems to be fixed just with switching the audio to PCM. at least I hope it stays that way!
did you have the video cut out as well as the audio? strange that the video would not also cut out if it was a line/node issue.
03-22-2012 02:33 PM
I had a long talk with them re this. And yes they go straight for the equiptment. I live at the end of the line so it may be the case. Anyways, I am calling them later today to voice my concern and raise my voice a little. The guy looked at the forum and said little. I do have a motorola box -fyi. Anyhow, we'll see how it goes, hopefully for their sake they fix it as I just lost my job and not in the mood for dilly dallying around. I feel sorry for them now - if they don't fix it they owe me a credit for not providing a service I am paying for(and yes my wife is irritated about it now).
03-25-2012 12:16 PM
let us know what happens. does it get fixed when they adjust things on the pole or do they have to change your box settings?
also, from other posts, it appears that switching to a higher end DVR box may take care of the problem too (although then you must pay for monthly DVR service too).
03-26-2012 11:24 AM
I am also having a similar audio problem. My problem seems to be limited to CBS and USA. Local CBS news programs are imposible to listen to. The verbal and any background music are both affected The ads and remote reporting are less affected then the studio reporting. I purchased a new TV about 6 weeks ago and that is when the problem surfaced. My old monster TV did not exhibit the problem as far as I could tell. I had Comcast out for the problem and they put in a new Motorola box. The USA channel shows that are most affected are NCIS reruns.
03-31-2012 08:47 PM
comcast was out today...said the box in the yard was wide open with moiture and spider webs. service was called to fix it. if it doesnt then the nodes will be next. ill let you know what happens next.
04-06-2012 06:28 PM
Well, supposedly an attempt has been made to correct my audio problem. However, there has not been an improvement. There supposedly was an open box somewhere. Comcast service techs visited in March and did check the connection at the street. How did this box open up? In conclusion: No Improvement.
04-20-2012 10:47 PM
On to the third service call tomorrow. I keep telling them about the nodes but they said they have a process to follow. A waste of time in my view when it appears clear what may be the issue. Anyways, we'll see how this one goes. If they can't fix it then I'll be asking for more credit for poor service.
04-21-2012 08:54 AM
On or about April 18 the audio problem has apparently been repaired. I don't know if Comcast made repairs or if the change over to HD by WHP, Channel 5 resulted in the correction.
06-26-2012 01:36 PM
The problem comtinues....I have had I think 6 or 7 techs out so far. They check everything and all comes out ok....I have had 3 new lines put in...very irritating to say the least. I tell them all that they need to review the nodes....thye can't as I have a good signal. The last guy said he ...have to go for now
12-27-2012 12:20 PM
you could try going to comcast and ask them to switch you to a different box
mine still works fine on PCM. but every so often the box changes itself back - so i have to change the settings again to PCM.
