Hook mz506 surround sound to my Samsung tv


Typically surround sound is run through a receiver or stereo. The sound from the tv is carried to the receiver by cables (hdmi or Audio-Video connected to input area of receiver). Then the speakers are connected to the output area of the receiver.
If you are not using a receiver, then the speakers must be able to connect directly to the tv and you have to see what kind of cabling your tv supports.

No sound coming out of speakers tuner or cat/tv


Please add details of setup so I can help you. For example. My Directv box hooks into my HDTV HDMI. Sound is carried inside that cable. I then get sound on my TV from my Directv RCVR without any other hookup. But I do have more. I use an optical cable to go into my Denon 1312 TV/optical input. Since my Wii, PS3, VCR, and formerly Xbox360 all plug into the HDTV inputs and I use it to switch. The Denon is not HDMI capable so this is best for me.

This is the first thing I would try. hook the HDMI to your HDTV from the CATV/SAT box and turn up the sound on the TV. [Box and TV on and correct input used] If you hear audio, the hook it back up as before. Now, turn on the Denon to radio. and turn it up. Got sound?
NO: check speakers and speaker setting. Let's say you have speakers hooked to A but not B. is the selector on B or AB. That won't work. It has to match the hookup. If speakers are on A only, select A only, etc. Also check with known good speakers. Also check all cables to be plugged into the correct spot and plugged in fully.
Thanks PM me if you need more help.

I'm trying to connect a Samsung HD LCD tv to a Denon AVR1508 receiver using HDMI cable so that the TV sound comes thru the receiver/speakers. which jack do I use (on both the tv and the receiver,


connect the hdmi to the tv (hdmi input 1) and to the receiver (hdmi output) you must make sure that the receiver input settings are assigned correctly. Then hook up all of your devices to the receiver. remember that the 1508 dosent do hdmi upconversion, so if you have any devices that are NOT hdmi, you need to run rca cables from the output of you receiver to the input of your tv. If you have any digital inputs coming out of your devices, i would recommend using them. your 1508 has two inputs that are assignable.
If all of your devices are hooked up to your receiver, and its hooked up to your tv properly, just turn down the sound on your tv, and turn up the volume on your denon!

No sound when hooking up DVi to HDMI...


This is normal, when you go from HDMI to DVI, the sound does not get transmitted. You need a separate cable to go from audio output on the computer to Audio input to the TV. There are speaker (headphone on laptop) jack to RCA audio cables, you could also go with digital audio or even optical out if your computer and TV both have the input and outputs.

NO SOUND WHEN USING HDMI FROM PC TO HDTV (RUNNING VISTA)


When using an HDMI to DVI cable their is no audio that comes through that cable. Even if you use HDMI to HDMI most computers only have video output from HDMI. You will have to use a seperate audio cable for you to be able to get the sound to work. Depending on the output you have on your laptop you may have to resort to hooking up a pair of speakers to the headphone jack.

Hope this helps.

XBox 360 to Reciever to TV via HDMI no sound


I recently got the same receiver and had the same problem. Here's what I was told - and it worked for me:

Even though HDMI cables carry audio and video, for whatever reason this reciever won't accept audio through hdmi. Apparently only much more expensive recievers carry audio through hdmi. What you have to do is run optical audio cables from your xbox, cable box, dvd player or other video device to the optical inputs on the back of the reciver. Then you customize the scene buttons to match your video and audio inputs.

You can get these optical cables pretty cheap on line or even at target. Don't get ripped off by Best Buy for these cables. I love best buy, but they rip off on cables!

This receiver is great - once I got it all figured out and running right I've loved it! Hope everything works out for you!

Compaq wf 1907 monitor speakers--no sound


No sound from monitor speakers
If the built-in speakers on the monitor do not produce sound, perform each step that follows, testing for sound after each step, until you can hear sound:
  1. Close the software program you are using that is experiencing the sound problems. Test for audio using another software program.
    If the volume is adequate using another software program, the issue is with the computer, not the monitor. If the volume is still low, continue with this procedure.
  2. Check the cable connection. If the monitor-to-computer connection is a VGA cable (usually blue on both ends), an additional audio cable is needed between the monitor and the computer. Check that the audio cable is connected properly.
  3. Try to adjust the volume higher using the monitor front-panel volume button.
  4. Using the buttons on the monitor, navigate through the onscreen display (OSD) menu to find audio or speaker settings and enable the speakers.
  5. Click Start c01292216.gif , Control Panel , and then click Sounds and Audio Devices .
  6. From the Volume tab, check the Device volume, and make sure it is not muted.
  7. From the Audio tab, in the Sound playback field, click the Volume button. Make sure the audio device is not muted and the volume outputs are at adequate levels.
  8. If the monitor-to-computer connection is an HDMI cable, an additional audio cable might be needed, depending on the setup and configuration of the system. To find out whether an additional audio cable is needed, go to

HDMI sends both audio and video through the same connection. If you want to hear audio from an HDMI connection, HDMI audio must be set through Windows .

Use the following steps to activate HDMI audio on your computer:

    NOTE: If you are setting up your computer for the first time, it may be easier to use a DVI connection or DVI-to-VGA adapter connection for the initial setup. Then, if you want to use an HDMI connection to connect a TV or monitor, activate sound for the HDMI connector using the steps that follow before connecting the HDMI cable to the TV or monitor.


    NOTE: After recovering the computer using the Recovery Manager, repeat this procedure to activate sound for the HDMI connector.

Step 1: Enabling HDMI sound in the BIOS
To hear audio through the HDMI connector to a monitor or display, enable the Onboard Audio setting in the computer BIOS settings by completing the following steps.

    NOTE: If you choose the default BIOS Setup options or upgrade the BIOS, you must repeat this procedure to enable audio for the HDMI connector.

  1. Turn off the computer.
  2. To enter the BIOS, turn on the computer and press the F10 key repeatedly until a BIOS Setup screen opens.
    A BIOS Setup screen opens.
  3. Press the right arrow key on the keyboard to select the Advanced tab.
  4. Press the down arrow key to select Onboard Audio , and then press the Enter key.
