HDMI to DVI Monitor Will Not Play Audio

Thanks for the suggestions, Deepika. I have a Samsung SyncMaster HDTV monitor and a SHARP monitor. I'm trying to get audio on the Samsung HDTV. I'm not sure if you need an audio cable when connecting to the HDTV. Anyways, I kept it on the television. Either
way, it doesn't work. I ran the troubleshooter, and there isn't any problems. I tested all the cables yesterday, and everything works as usual. How are the HDMI cables supposed to connect and work with video and audio? Is there a driver problem? I believe
it might be because my monitor is in the DVI port, instead of an HDMI. This is why it's not detecting on the sounds/playback devices. Plugging an audio cable in the secondary monitor with VGA works, but using an HDMI for the television does not. Using VGA
for the television does work with audio. Not sure what the problem is, or if I have to plug the audio cable in the HDTV at all. Any help would be appreciated! Thanks!

UPDATE: Figured out the problem, testing. The HDMI cable although supports audio and video, the DVI connector
does not. Because of this, the computer detects it as a DVI connection. It instead uses the regular audio cable. The television, however, does not. It detects HDMI first, and uses that as as the audio. Since there is no coming through the DVI
connector and instead coming through the audio cable, it won't play anything. This can be half solved by changing the source device (source>edit name) on the Samsung television to HDMI DVI. This, however, does not fix it, as sound still doesn't come out. The
computer still has to be changed to be able to play audio properly. Any suggestions on how to fix this?

 

HDMI to DVI cable

HDMI and DVI are 100% the same with video. When they desigend HDMI, they used DVI as a base design - think of HDMI as DVI, but they removed the VGA compatibility and replaced that with the audio signal.

If you want audio, there can be extra steps (for example, Nvidia need an SPDIF cable between your video card and your sound card, while ATI require a special DVI to HDMI adaptor, and a normal HDMI cable - you cant use a DVI to HDMI cable)

 

cant detect tv with hdmi

Hi,

Thank you for contacting Microsoft Community and welcome to Windows 10 family.

Please try with these steps:



1. Right click on the Desktop.

2. Choose Screen Resolution.

3. Let’s see if TV has been detected. If not, press “Detect” button.



Also go through the below steps:



Step1:



Choose the connection for video output. If your computer has an HDMI port, otherwise, you will need to make a few decisions. If your computer has only a single video output, and it will not be used solely with the television, you may want to invest in a
new video card. Purchase one with either a DVI or an HDMI output, and install it in an available slot, according the instructions included with it. If you intend to use the VGA output on a single-output or dual-output card to drive the HDMI display, then a
special device will be needed to convert between the formats, and the price of the converter is actually about the same price as an entry-level video card that will be easier to use with your TV. In that case, it may be a wise idea to upgrade the card in order
to obtain a DVI or HDMI port. However, if your chosen output port is of the DVI variety, an inexpensive DVI to HDMI cable can be purchased to convert your computer's output into the proper HDMI input for your TV.



Step 2:



Connect the HDMI cable from your television to your computer. Install the correct adapter or converter for your computer, if necessary. Unless your computer has HDMI output, cords will also need to be connected from the sound card output to the HDMI video
cable or adapter, because HDMI carries both video and audio signals.



Step 3:



1. Boot your PC, and configure the new display,

2. Go to "Control Panel" from the "Start" Menu.

3. Double-click the "Display" icon and click the "Settings" tab.



The manual for your HDMI TV will list the screen resolutions it supports, along with the refresh rates.

Configure the resolution in the "Settings" tab, and then click the "Advanced" button to set the refresh rate.

If you are using the HDMI TV as the second monitor, you will also have to configure how it is used by Windows, according to the instructions pertaining to your video card. Most cards offer a "Clone" or "Mirror" mode, where both screens display the same content.
Alternately, the "Extended Desktop" mode can be used, in which each monitor will operate independently.

Hope this helps. Please post us if you need any further assistance with Windows.

Thank you.
