Trying to connect a sony home theatre system so that the akai television plays through the home teatre speakers. I used an hdmi cable, but the tv still only plays threough the tv.


The HDMI jacks on the TV are HDMI in. Thus to get the theater system to play the sound, you use the HDMI out from your set top box to the HDMI in of the Sony theater system and then the HDMI out of the theater system to the TV. (Connecting the HDMI in of the TV to the HDMI in of the home theater system will not work.)

If you are watching OTA TV or a direct coax cable connection, you need to hook up the TV audio out to the home theater system audio in to use these speakers with the TV. Then you probably need to set the TV to use the external speakers. This will probably be in the Menu under Audio. (Toggle external speakers on/off)

The Akai LCT2785TA has RCA audio out (1/4" red and white jacks). If your home theater system has RCA audio in, just get a patch cable (MM ends on each side of the cable). If your home theater system only has digital audio inputs, you will need a converter. http://www.ramelectronics.net/audio-video/audio-converters-extenders/analog-to-digital-digital-to-analog/1t-ap-216/prod1TAP216.html is a link to one appropriate converter.

I hope this helps.

Check the input selector on the TV, if you have audio only then it is a cable problem,
that means that cables are not connected in the right way.

It's possible that you have the wrong type of HDMI cable. You need one that has Audio Return if you want to feed your Home Theater system with audio from the TV. There are several types of HDMI cable,some with audio return and some without. The two basic types (not including Ethernet) are described below - you need the High Speed version, which does have Audio Return.

hdmi-standard.jpgHDMI Standard This is the most basic HDMI standard which all cables have to meet. Cable should contain all the connections required for HD transmission, and have to deliver at least a resolution of 720p, (Video mode of 1280 x 720 meaning 720 Horizontal lines). These cables do not contain an Ethernet connection, or audio return.

hdmi-high-speed.jpgHDMI High Speed HDMI High Speed cables will support higher resolutions of 1080p. This means at least 1080 Horizontal lines, and cables rated at this specification may well support high resolutions of up to 4096 x 2160 (2160 Horizontal lines), check individual cables specifications for this data. Cables in this specification will also support a data transfer speed of 10.2Gbs (not to be confused with ethernet data speeds which are different), and a clock speed of 320Mhz. These cables do not contain an Ethernet connection, but do include an Audio Return Channel.

How do I get tv audio out of my surround sound HT3550U. I have HDMI cable in and function turned on TV audio. I also have LG TV. Any Ideas ???


What is the TV source?

If you have a coax (antenna or some cable systems) to the TV, then you need to connect the surround sound system to the audio out of the TV. Depending on the TV, the output could include Digital audio, RCA audio (red/white) or a headphone jack. Without knowing which LG TV model, I can't be sure which ones you have. Get the best cable for your TV/receiver system and connect that. Then set the TV to use the external speakers.

If the source is a set-top box, then the cables should run HDMI from the box HDMI out to the receiver HDMI in and then from the HDMI out of the receiver to the HDMI in on the TV. (Most TVs do not have HDMI out.) If the unit still doesn't play the audio, first try new cables and make sure the correct source is selected (some receivers have multiple HDMI in). Make sure the speaker cables are all connected (if they have separate connections) and that everything has power. (One of the usual speaker system problems in my house is loose cables from someone knocking against the back of the entertainment center and pulling.)

If you need more help, please provide more information on your equipment. I will do my best to help you diagnose the problem.

Hello,

Adjust the system's audio output settings. These settings are mainly used when the system is connected to audio devices that support digital audio output, such as AV amplifiers (receivers) for home entertainment systems.
1.
Confirm the formats supported by your audio device.
Settings vary depending on supported formats. For details, refer to the instructions supplied with the audio device.
2.
Select in_soundset.gif (Sound Settings) under in_setting.gif (Settings) in the home menu.
3.
Select [Audio Output Settings].
4.
Select the input connector on the audio device. Channel numbers and audio formats that are supported vary depending on the connector in use.

Select audio output formats.
Select all output formats that are supported by the audio device in use. If [Audio Input Connector / SCART / AV MULTI] is selected in step 4, the screen for selecting audio output formats will not be displayed. If [HDMI] is selected, you can also select to automatically set the audio output format. (In this case, the HDMI device must be turned on.)
soundoutput003.jpg 6.
Check your settings.
You can go back to the previous screen and revise the settings by pressing the in_left_key.gif button.
soundoutput002.jpg 7.
Save your settings.
The audio output settings are saved on the system.
Hints
  • [Linear PCM 2 Ch.] audio is set to be output from all output connectors by default. If you change the audio output settings, audio will be output only from the connectors that were set.
  • If you change the audio output settings, the system will no longer be able to output audio from multiple output connectors at the same time. For example, if your system is connected to a TV via an HDMI cable and to an audio device via a digital optical cable and you switch to [Digital Out (Optical)] under [Audio Output Settings], audio will no longer be output from the TV. To output audio from the TV, switch the setting to [HDMI], or select in_setting.gif (Settings) > in_soundset.gif (Sound Settings) > [Audio Multi-Output] and set the option to [On].
  • If you select [Linear PCM 2 Ch. 88.2 kHz] or [Linear PCM 2 Ch. 176.4 kHz] in step 5, sound may be intermittent or may not be emitted from some audio devices.
  • When using an HDMI cable, only [Linear PCM 2 Ch.] audio will be output from PlayStation®2 and PlayStation® format software. To output Dolby Digital or DTS audio, you must connect the PS3™ system and the audio device using a digital optical cable and switch to [Digital Out (Optical)] under [Audio Output Settings].
  • If a device that is not compatible with the HDCP (High-bandwidth Digital Content Protection) standard is connected to the system using an HDMI cable, video and/or audio cannot be output from the system.

HDMI audio in this setup is a one way street. Audio will not come back from the TV to the audio system.
Sorry as you have not shown the model number I can not advise on the system fully.
However, it is standard on the current Panasonics to use Optical audio as a return feed or phonos.
Optical would be best as it carries full digital surround, whilst the phonos only carry "surround"
It may help for you to look a the new Panasonic web sit as there is now an interactive "How to connect your system"

If you are not connected to HD, pixelation can easily occur, especially if you are using an analogue connection. Here is a list, from best to worst, of how you should connect the video on your system.

1) BEST - HDI cable between the TV HDMI in and the sky box HDMI out. This is a full bandwidth digital audio and video connection.

2) BETTER - S-Video between your TV and sky box (with L & R audio)

3) GOOD - Component Video with L & R audio

4) STANDARD - single video cable (yellow) along with L & R audio

5) standard coax

These are listed, as stated, from best to worst quality. If you are not using a digital connection (HDMI), then pixelation can be expected.

Please help with getting 5.1 sound from my TV!


You must run a Digital Optical cable from your PS3 to your reciever. Then press your function button on your recievers remote until you see SAT/CABLE on your recievers display. Next go to your PS3 settings and go to Sound settings, then Audio Output settings, and select Digital out (OPTICAL) then your done. This is the only way to get true digital sound from your PS3 to your reciever.
