    I just bought the Insignia 26 inch lcd from future shop and have the same problem so I hope this belongs here. My new Motorola 505 HD sat receiver does have dvi no hdmi but I went out and bought the dvi to hdmi converter and there was no sound. Using the AV input on the side of the TV the dvd player and game console's audio/video worked fine.

    I tried the 3 component cables that came with the HD receiver and attached separate audio cables (several different ones to make sure it wasn't the cable) and still no luck. I then tried a process of elimination by hooking the Insignia to the same model receiver that works perfectly with my LG. I did get audio but this time the picture was seriously degraded (barely any colour) with bright coloured vertical lines that moved in synch with voices. (ie: the lines would diminish when conversations were becoming inaudible and then the lines would move up again when the voices became louder and so on much the same as a frequency analyzer looks. This is a very weird problem that the original poster experienced and then some.

    Does any of this sound familiar to anyone? Thanks in advance.

Is it possible that the output on your HD cable box is actually DVI and not HDMI type? the reason I mention is because the majority of HD cable boxes still have DVI outputs which CAN be converted to HDMI but DO NOT carry an audio signal, which would explain what is happening to you right now. If you DO have a DVI connection on your box as I had guessed then all you would need to do now is either hookup standard stereo RCAs from your cable box to the TV or preferrably, an optical digital audio cable from your HD box to the TV. good luck!

It may be the top of set box.. Most times the sound and picture are auto detected by the set when HDMI is used. Both sound and video are carried in a HDMI cable but not with a S video cable. Try another HDMI cable *** dont buy the expensive one the tv don't care if they cost $125 or $25.

Losing sound momentarily


Are you using an HDMI cable and a digital box from your cable/sat company?

HDMI supports 2 different audio formats and when using a box from your provider sometimes the tv thinks the other format is available and switches to if for a few seconds.
Try using a HD component cable, they have Green, Blue, and Red video with Red and White audio, if the issue is your TV switching between formats this should fix it.

It could be the version of hdmi cable you are using. It could also be what version hdmi the television is vs. what version hdmi cable you are using vs. what version hdmi the hd box is. See if you still get this problem when you use component.

It isn't impossible at all. You may need a sound bar if you don't already have a Bose surround sound system or a boom box or something else you can use without purchasing anything. On the hdmi/dvi televisions and cable boxes of the recent past there would always be an accompanying white and red composite/RCA slot (output on the cable box, input on the television) to accommodate this. You would simply connect the hdmi to dvi cable from the television to the cable box and then the red and white audio cable. If your television and cable box does not have the red and white composite/RCA audio input and output you will need to connect the cable box to an external audio source. How to do it and what to connect it to depends on what audio output that is on the cable box (usually is on the back of it). You might need a fiber optic cable and a sound bar with a digital audio input if you have a newer cable box.

Your cable box most likely has a setting for audio HDMI such that HDMI sound is turned ON etc. rather than standard audio. Also check the TV settings for HDMI audio being set to ON. This should be a simple fix. HDMI audio usually is just a user setting adjustment and nothing more. Somewhere in your on-screen menus you should find the place to adjust HDMI audio.

Can record Sky programmes but not view live.


You must connect up the TV to the SKY box, via Audio Visual cables too, in order to watch, recorded programs. You need to hook, up, Component, HDMI, or Composite, You select it by an EXTERNAL channel.
Connect the cable running from the wall into the "In" port on the Sky Box HD receiver. This cable brings in the signal to your receiver. Make sure the cable is securely fastened to the receiver, otherwise you might experience image and audio issues.
Attach an HDMI cable into the HDMI port on the Sky Box HDTV receiver. The HDMI is a single cable that provides both HD audio and video signals.
Plug the other end of the HDMI cable into an available HDMI port on the HDTV.
Power on the HDTV and the Sky Box HDTV receiver. Press the "HDMI" button on the TV's remote control. This will display the cable contents of the HD receiver onto the television.

Sound only works with HD, not SD


Check the setup menus of the Insignia TV, as most sets have an advanced setting hidden deep in the setup menu to use the HDMI cable for sound - OR- use component RCA inputs for sound. My Philips TV has this.

It's odd that this only shows up for SD content...I would see if there is a firmware update available for that from the manufacturer. The one thing that you see lots of firmware fixes for are HDMI issues.

Need help hooking up TV, BluRay, Home Theatre & cable box


I found that since the Panasonic TH50PZ80U TV has only 2 HDMI ports on the back of the TV, the best solution for me was to use component (red, blue, green) cables to connect the Home Theatre to the TV. I suppose I/you could connect the home theatre to the HDMI port on the front panel, but I don't want cables hanging out the front of the TV (personal preference). Unfortunately, I am no longer able to use the VIERA Link functionality available by connecting all Panasonic components to each other using HDMI cables, but I feel it's a small price to pay for the incredible picture quality acheived by using the HDMI cable to connect the HD Cable Box to the TV. I may yet be able to control everything using the HD Cable Box remote, but I haven't gotten that far yet but I've got Comcast coming on Saturday and hopefully they can let me know if this is possible: let me know if you have a solution.

So here are the components and the cable types used to connect:
  1. HD Cable Box to TV: HDMI cable & Optical Audio cable
  2. Home Theatre to TV: Red, Blue & Green component cables
  3. BluRay Player to TV: HDMI cable
I hope this helps someone else.

No Non-Hd sound


I had the exact same problem on a brand new Insignia 26 " LCD with DVD. Comcast tech was able to fix it by changing the Comcast box diagnostics. Here is what he did. Using the Comcast remote with the TV on - press power, cable, menu in that order. A comcast diagnostic srceen will appear. Select Additional HDMI options, then audio options. Change the audio options to L-PCM. Press power again to exit the diagnostics. That will fix it and you get to use the HDMI cable.

Set up


Seems that Hitachi DESIGNED the sound to cut off from the Audio Out jacks if you use component video or HDMI inputs. Has to do with copyright laws of the HD Video -- which makes it asinine that they disabled the audio as well, as it's not part of the copyright issue. Seems to me they were just lazy to disable the ENTIRE set of output jacks.

I am hoping to find some sort of hack for this (either firmware or severing/splicing a control wire). However, I can't find much information on this yet.
