If hdmi cable sends audio and video info from my laptop to my tv why can't I hear anything? I have video but no audio. the Audio all say hdmi/high def audio and are working properly

You'll need to update your cable box with one that has an HDMI out port on it. Nothing else will work.

I'm confused, are you trying to use a VGA cable for both video and audio? VGA cables don't have sound built into them, nor do DVI. If you had an HDMI plug on your laptop it would be best to go with that since HDMI contains video and audio.

You could just use an Aux cable from laptop to TV. Pretty much it would be a aux to analog type. It's like a speaker plugin, that side is for your computer. Then the other side coming out would be an analog red/white or left/right cable.

Another one, if your TV supports pure aux cable (it's a 3.5MM jack that speakers plug into) Like, my tv has a built in aux port for audio for my computer. So I just use pretty much a standard cable to cable setup.

"In the past I have got the old flat TV connected with SCART"... what about the present? HOW is the "TV" audio connected to it?

My advice would be to remove the TV as a sound source and get the TV-audio from the audio outputs of wherever it really originates. In most cases that is a Cable Box which can be treated like a high-end audio device for this discussion.

Ever wonder why Cable Boxes have separate audio and video outputs and TV's have multiple inputs? So you can send the BEST version of audio and video directly to the BEST electronics that NEEDS it and NOT to or through anything that adds nothing to the quality. Heck, many TV's are monitors without audio at all. THAT is how I would treat any TV for serious high end listening. Send the digital Cable Audio to the soud system and the 'regular' RCA audio to the TV for low-fi TV-watching like news and Oprah.

Not likely that all those things are faulty.

The TV and DVD player make and model would be helpful to know. I would recommend running its BEST digital audio to the receiver and its stereo analog audio to the TV just in case you want to watch and hear the DVD in a lo-fi setting without the Denon. I generally advocate for connecting anything high-end (audio or video) ONLY to equipment that can use it or enhance it. Otherwise you may just be wasting expensive cable and adding unnecessary hops and connections that can fail.

Why do you want the audio to go from the DVD to the TV through the Denon? Are there no speakers on the Denon? Modern TV's have lots of inputs for the flexibility I recommend but rarely have decent audio or speakers.

Its a vidio/audio input which looks like this. If you have an hdmi port on a laptop you can connect it to a TV and have the audio and video transfer to the TV.

What TV audio is available to the SC-BT100 that a) isn't available to the TV directly; and b) would sound better on the TV?

I'd look on my cable box for the basic analog audio out and send it to the TV for those times you just want to watch the news without hi-fi. I'd also send the best Video (HDMI) directly to the TV because passing it through the receiver just adds cabling and opportunity for malfunction.

The best audio should go directly to the Panasonic. Period.

Look around fixya for the most common video problems - not passing through the receiver unscathed.

The HDMI just give you the video in High definition without audio. Connect a cable with the stereo connector in both side, one side to the computer (on the head set connector) and the other side to the tv (audio pc in). You can buy the cable in Radio shack or computer store like Comp USA or Best Buy.

Hello

The HDMI[1] input on your TV receives digital audio

and uncompressed digital video and audio from an

HDMI device or uncompressed digital video from a

DVI[2] device.

This input is designed to accept HDCP[3] program

material in digital form from EIA/CEA-861/861B-

compliant[4] consumer electronic devices (such as a settop

box or DVD player with HDMI or DVI output).

The HDMI input is designed for best performance

with 1080i high-definition video signals, but will also
accept and display 480i, 480p, and 720p signals.

To connect an HDMI device, you will need:

• one HDMI cable (type A connector)

For proper operation, it is recommended that you use

a short HDMI cable. You should not encounter

difficulty if you use an HDMI cable shorter than 16.4

ft (5m).

HDMI cable transfers both video and audio.

Separate analog audio cables are not required (see

illustration below). Some CDVs (video CDs) may

not output digital audio signals. In that case, you

may hear sound by connecting analog audio cables.

However, if you connect analog audio cables with

this connection, the HDMI terminal on the TV will

not receive the HDMI digital audio signal and you
will hear analog audio only.

To ensure that the HDMI or DVI device is reset

properly, it is recommended that you follow

these procedures:

• When turning on your electronic components,

turn on the TV first, and then the HDMI or

DVI device.

• When turning off your electronic components,

turn off the HDMI or DVI device first, and
then the TV.

To connect a DVI device, you will need:

• one HDMI-to-DVI adapter cable

(HDMI type A connector)

For proper operation, the length of an HDMI-to-

DVI adapter cable should not exceed 9.8 ft (3m).

The recommended length is 6.6 ft (2m).
• one pair of standard analog audio cables
OK

The first step is to inspect both your laptop and TV and identify the connections, easily located on the back of either component. There are five basic types of jacks, or ports involved:
*Composite/phono plug (RCA)
*S-Video
*Video graphics array (VGA)
*Digital video interface (DVI)
*High-definition multimedia interface (HDMI)
*An RCA connector, sometimes called a phono connector, is used for analog audio and video components. Three round, colored sockets are standard — left audio is white, right audio is red, and composite video is yellow. These are standard jacks on older TV’s and laptops. A three-prong cable, readily available at any computer or electronics, is the easiest way to make an RCA laptop to TV connection.
*S-Video, or Super-Video, a more advanced analog video connector, uses a four-prong round plug, like those used in TV cable installations. Separate audio cables are the same as for the RCA connector, left audio/white, and right audio/red. S-Video is commonly found on older TV sets and some laptops.
With S-Video on both TV and laptop, connecting a laptop to a TV is a simple matter of a single S-Video cable. If your laptop has a great sound system, you won’t need audio cables, but for better quality you’ll also want audio cables.
RCA to S-Video cable, a special laptop to TV cable, is available when you have RCA jacks on one device and an S-Video port on the other.
*A VGA connector and cable are used to carry analog video signals plus display and graphics data. The VGA is a 15-pin connector commonly found on laptops and other devices. With this port you need a PC-to-TV Convertor to connect laptop to TV. You simply plug the VGA cable from the source into the convertor, and use an S-Video or RCA cable out to the TV. The converter is USB powered, so there’s no external power adapter to carry around, making this laptop to TV connection entirely portable.
*A DVI port is rectangular with 24 pins arranged in three horizontal rows of eight pins for digital video; separate RCA analog audio cables fit into white and red plugs. DVI ports are found on Macintosh laptops; sometimes they are smaller than normal DVI ports and require an adapter, which usually comes with the laptop.
*The HDMI port, one-half the size of the DVI port, is also rectangular with 19 pins. It provides digital audio in addition to digital video, despite it’s smaller size, for a complete TV to laptop connection. These ports are found on new HDTVs, and sometimes there are two or more. TVs with HDMI ports are the only ones that do not require additional audio cables.
TV’s with a single digital port labeled HDMI/DVI require only one cable when the source is another HDMI component. But when source is a DVI laptop, you need a DVI-to-HDMI cable for the video and a separate pair of RCA analog stereo cables.
NOTE: Whenever ports do not match, you can by adaptors and/or cables to make any connection.
