What s going on with a desktop computer with no sound on the TV?

Normal. The fault is in the software, and the software adopts a step-by-step elimination method. The first step, the computer can be normal****, first exclude the driver (note, not all excluded has something to do with the driver.)

If normal. Check your TV series source to see if there is any sound. If all of the above is fine, reinstall the driver on your computer.

Note: In the case of not being able to see, based on personal experience, the problem may be in the ** device or the source. After I finished writing, I saw that there was already someone.,Then I'll take this non-writing.,-Drive the elf.。

- The driver is installed, there is an update driver inside, select the sound card update driver, if the prompt is already the latest driver, then remove the sound card driver, install it again, try again after installation, if not. Then remove the sound card driver and install it from a new** lower version of the sound card driver. Oh yes!

That's all.

Check from the following aspects.

1. Whether it is in a mute state.

2. Whether there is an external speaker, and whether there is a poor contact with the speaker wiring.

3. The volume knob is not in the minimum position.

4. Is the earphone plugged in?

5. There is a problem with the sound card driver, recently, is it deleted files that should not be deleted.

6. Finally, it is a problem with the computer hardware, especially not the sound card.

Check that the volume is turned up to the maximum. If you want to use the computer to put the TV,Check two volumes,One is the system volume that comes with the computer itself,The other is the volume on your **software,Both sides must make sure that it is turned on,In order to have sound normally。

There is no sound from the external speaker of the desktop,In addition to the sound card is broken, it is a reason,There is another reason that the interface is loose,Or oxidized,Resulting in bad contact,I encountered this situation at the time,There is sound when I touch the interface wire,Of course, it was a moment,After letting go,There is no sound again,This is obviously the interface is broken,Whether the sound card is broken or the interface is broken,It's the same,You have to change the sound card,This is different from a notebook,The notebook has its own speakers。 If it's not for the sound card to be broken, there will be sound.

Or there is no sound on the computer on the TV,You can check whether the sound card of the computer is faulty,The sound card or no driver will not have sound,In addition, look at the external equipment of a ** computer,Whether the speaker is connected normally and there will be no sound if the connection is not smooth。

That's because you don't have a plugged cable, or the sound of the TV is not amplified, so there is no sound, or there is no sound on this station, and you think this TV is broken.

Check if there is an external speaker, desktop computers generally need an external speaker, and then the speaker is plugged in.

Check that the speakers are turned on, and then see if there is any problem with the sound card driver.

Check whether it is muted first, otherwise check the driver of the sound card.

Desktop computers don't have speakers, so if you want to make a sound, you either have headphones or external speakers.

The most likely reason is that the sound in the computer is not transmitted to the TV, that is, it is very likely that you are using a VGA cable to connect the computer to the TV (or a VGA cable connecting to the computer). If you must use a VGA cable, then you also need an audio cable to use it, and the audio cable is solely responsible for transmitting the sound from the computer to the TV.

If the computer is connected to the TV through the connection cable of the VGA interface, then due to the transmission characteristics of the VGA cable, the ** signal can only be transmitted from the computer host to the TV, and the audio signal cannot be transmitted, so that the sound cannot be emitted. At this time, if you want to make sound, you must use it with an audio cable, which is a cable with red, white and yellow connectors, so that the audio signal can be transmitted from the computer host to the TV, and the sound can be emitted.

If you use an HDMI cable to connect the computer and TV, then you can check and solve the problem by the following methods when the sound is not emitted:

1、First of all, right-click the "small speaker" style icon in the lower right corner of the computer desktop, and then pop up the menu bar and click with the left mouse button "**device", then you will enter the panel options of computer sound, at this time, in the digital output device"HDMI"Then right-click with the mouse to select"Set as default device",You can solve the problem that there is no sound when connecting to TV in HDMI。

2、The second method is,Use the right mouse button on the computer desktop"Computer",Then"Device Manager",Find in"Device Manager"Sound、**And Game Controller"Option,At this time, you only need to block the system's default sound card,This can also solve the problem of no sound after connecting to TV。

Many friends use the HDMI cable to connect the computer to the TV, there is no sound on the TV, but the HDMI cable itself supports sound audio transmission, why is this? The following is an introduction to the solution to the lack of sound from the HDMI link computer and TV.

Method 1: 1. Click the [Sound] icon in the lower right corner of the taskbar to check whether the sound is set to mute, and if so, turn on the sound.

2. Press the [Win] key + [R] key, enter [Run] and press Enter to confirm. In the Control Panel window, click Hardware & Sound, and then select Sound. Select Digital Audio (HDMI) in the ** tab of the Sound window, click the Properties button below, and select Use this device (Enable) in the Device Usage of the pop-up window.

Again, disable other audio devices.

Method 2: Right-click the icon of "Little Speaker" in the lower right corner of the desktop, pop up the menu bar, click [**Device (P)], enter the sound panel, and right-click "Set as Default Device" at the digital output device (HDMI) to solve the problem of no sound when connected to HDMI.

There is no sound when the computer is connected to the HDMI deviceSolution 1: Take win7 as an example, first of all, we right-click the icon of "small speaker" in the lower right corner of the desktop, pop up the menu bar, and click [**Device (P)], as shown in the figure below; At this time, we entered the sound panel, and then we can right-click "Set as Default Device" at the digital output device (HDMI) to solve the problem of no sound when connecting HDMI, as shown in the figure below: There is no sound when connecting HDMI devices to the computerSolution 2:

We right-click on the desktop [Computer] and select Device Manager, and find the item "Sound, ** and Game Controller" in the Device Manager, we only need to block the sound card that comes with the default motherboard of the system, usually "AMD High Definition Audio" and "High Definition Audio", etc., and only use the sound card channel in the graphics card. The following gives the precautions for HDMI connection to LCD TV:1、HDMIalthough the interface supports hot swapping,However, considering the different devices and the different quality of the data cable,It is best to turn off the equipment。

2、Some TVs don't have the function of automatically searching for signals,So you need to manually set the TV to HDMI mode。 3. Check whether the graphics card driver is installed on the computer, and you can use the driver to install the driver. 4. Set HDMI as the default device in the audio properties in the computer.

5. There are also some motherboards with integrated graphics cards that must set the OnBard VGA Connect option to D-Sub HDMI in the motherboard BIOS, which is relatively small, there are no 10,000, only in case, refer to the following.
