Series 3 HD Frequent Audio Crack/Pop/Dropouts
Jan 26, 2007 at 6:06:08 PM  |  #1
[Archived]  
I've got a Series 3 HD, Comcast Cable, 2 cable cards, Sharp LC-46D62U TV, Bose LifeStyle 38 Series II. Here's what I've tried:

TiVo HDMI -> Sharp HDMI
Sharp Optical Audio Out -> Bose Optical In Result:
NO audio at all --- > seems to be a problem with the sharp not directing the HDMI audio to the Bose. Sigh, this would have been the best possible config from the ease of use perspective... But not TiVo's fault!

TiVo HDMI -> Sharp HDMI
TiVo Optical out -> Bose Optical In, Dolby Digital 5.1
Audio, but FREQUENT LOUD pops & cracks in audio, occasional audio dropouts for 1-2 seconds at a time.

TiVo HDMI -> Sharp HDMI
TiVo Optical Out -> Bose Optical In, PCM
Audio, but FREQUENT LOUD pops & cracks in audio, occasional audio dropouts for 1-2 seconds at a time.

TiVo HDMI->Sharp HDMI
TiVo Optical Out -> Bose Optical In, PCM
Sharp Analog Audio Out->Bose Analog IN, Select Bose's Analog input
Audio, but FREQUENT LOUD pops & cracks in audio, occasional audio dropouts for 1-2 seconds at a time.

TiVo HDMI->Sharp HDMI
TiVo Optical Out -> Bose Optical In, PCM
TiVo Analog Audio Out -> Bose Analog In
Audio, but FREQUENT LOUD pops & cracks in audio, occasional audio dropouts for 1-2 seconds at a time.

Where am I going wrong? How can I get HD video with acceptable Audio???? Is this a known problem? Is there a magical configuration that works? Is this possibly a defect in the TiVo Series 3 unit I just got?

Thanks!

I forgot to mention, the audio problem seems to occur ONLY with HD content. SD content is fine. So I'm not sure it's the temperature issue others have spoken of.

I've been having the same trouble. This is the only post I've found with someone else having this happen, so I'll probably call TiVo support in the next day or two.

I've tried two different optical cables, just in case that was the problem. In a lot of cases, it seems like just vocals of TV shows drop out, which probably implies its specific channels or something.

I have a PS3 and a DVD player hooked up with optical to the same receiver, with no such issues.

I have the exact same problem. I returned my Series 3 for a new replacement, but still having intermittent audio popping and crackling noise. I notice it most on NBC. My TiVo is connected directly to a Samsung HD TV through the HDMI input. Can't seem to figure out what the problem could be. It seems to pop/crackle frequently when going from commercial back to the TV program.

Anyone have any clues?

I'm having the same problem, isolated to a particular situation. When I go from the TiVo menu to "watch live TV" I get a pop from my subwoofer and a zap or static sound from the front and surrounds.

I've got it connected via the optical audio to my Nakamichi receiver, and I don't have this problem on any of my other components (connected via optical or not).

Has anybody had a useful response about this?

Try setting your tivo audio setting to dolby digital pcm. Also if you are having problems with your video resetting after exit from fast forward switch to component video.

The problem seems to be unique to Tivo HD (latest one, not the first HD) + Sharp:

Hopefully someone at tivo will buy themselves a sharp LCD (52d64u for example) and get this problem fixed...

I have the same problem, did jkm123's advice fix the issue? I hear popping sound when changing channel, when a recorded show comes to the end of play and now that ive got an OTA antenna the sound is ear piecing when the signal drops. 

Tivo HD (new one) is connected to Marantz 6001 through HDMI (also tried component). Haven't noticed the problem being specific to HD broadcasting only. TV is a Panasonic Plasma.

Kind regards Embarassed

"Try setting your tivo audio setting to dolby digital pcm"

I thought Dolby Digital and PCM were two different audio streams, the first being compressed audio utilising 5 channels of sound, the latter, PCM being raw audio but only two channels?

Which do you mean, DD or PCM?

Many TVs do not handle DD well. Therefore, if there is a problem with the DD audio when using the TV speakers the recommendation is to use the DD > PCM option to convert the audio to two channels stereo.

However, you mentioned a Marantz 6001.  I assume that you mean the SR-6100 which is a 5.1 AV receiver.  Are you having the problem when using the Marantz speakers, or the TV speakers?

You said that you connected the TiVo to the Marantz with HDMI.  How is the Marantz connected to the TV? HDMI?

Thanks for the reply.......the TV is connected to the Marantz using HDMI too.  The speakers being used are not the TVs, but some stand alones connected to the AV receiver. Marantz are no help on the issue, they ask me to replicate the conditions on another device to see if it's a probelm with the 6001, but how can you replicate channel hopping on a DVD player? Do they want me to buy another Tivo and test it?! 

Tivo arent very helpful either, they claim no known issues with popping sound and charge you to take it back and fix it, even though from day one it's been faulty.Yell

did I mention that the tivo 'bub bub bub' sound effect is often muted when fast forwarding or doing general menu activity. Cool

I had the same problem (in a series of several other problems) and it did seem to be worst on NBC.  One time when a Comcast tech was in the house for another reason, I showed it to him.  He immediately said that it was a bad sound card.  He went on to say that he had seen the problem in other TiVo's and even some Comcast DVRs.

Since I had exhausted all other possible explanatiinsm Tivo exhanged the unit.  Now I no longer get popping, but I am not able to get any channels either ("Loading Channel Linup" doesn't complete ).

I had the same problem for weeks with my new HDXL Tivo and TV.  Specifically, I had clicks, pops, and screeches while fast forwarding or rewinding on HD content. 

My setup - HD Tivo to Insignia Plasma via HDMI.  Plasma is connected to Soundstage soundbar via optical.

My solution - Within the Tivo messages/settings --> Audio --> Dolby Digital menu I changed from "Dolby Digital" to "Dolby Digital to PCM"

Voila - no more clicks, pops, or screeches...

Now if I could just figure out to keep the commercials from being so D$&# LOUD!!

By "same issues" do you mean that you also have a TiVo HD connected to a Marantz receiver and Panasonic Plasma and are getting the loud pops when you change channels?

If not, please describe your setup and specific problems.
