I want to quit using the Realtek speakers that I added to the computer and go back to my monitor speakers, but now I can't figure out how to get them to make a sound.

1: check the speaker wire. it should connect to a green port at the back of the computer.
2. In control panel open realtek audio device manager. it will tell you where its connected
3. If its a monitor speaker then do a factory reset for the monitor.
4. try to configure the speaker from audio device manager on the system tray volume icon
still doesnt work then uninstall the driver for sound card from device manger
restart the computer
still no then do a system recovery

This document pertains to HP or Compaq PCs with an HDMI (High-Definition Multimedia Interface) connector for connecting a monitor or TV. If you use HDMI to connect your display, you must activate HDMI sound by adjusting your Windows settings . If HDMI is not activated, you cannot hear any sound. Because of this, HP recommends that you connect analog speakers to the computer to hear sound during the initial setup of the computer. Use the following steps to activate HDMI sound on your computer: NOTE: If you ever perform an HP system recovery, you must repeat this procedure to activate sound for the HDMI connector.

1. Right-click the Volume icon by the time in the lower-right corner.
2. Click Playback Devices . The Sound window opens.
3. On the Playback tab, click Digital Output Device (HDMI) if it is listed. If it is not listed, click Realtek HDMI Output . Figure 1: Digital Output Device (HDMI) selection Figure 2: Realtek HDMI Output selection
4. Click Set Default .
5. Click Apply .
   • If you used Digital Output Device (HDMI) , click OK to close the window. This completes the steps to activate HDMI sound.
   • If you used Realtek HDMI Output , continue with Step 6.
6. Double-click Realtek HDMI Output . The Realtek Digital Output Properties window opens.
7. Click the Supported Formats tab.
8. Place a check in the 48.0 KHz check box, and make sure that there are no checks in the Dolby Digital check box and all other check boxes. Figure 3: Supported Formats settings in the Realtek Digital Output Properties window NOTE: For most TVs to play back audio, the sample rate must be 48.0 KHz.
9. Click OK to close the window.

Hi: I'm sure you checked the volume control of the Bose controller. Check where you plugged it in to the back of your computer. Mine has a veriable outpup and a fixed output. I hope this helps, Jeff

You need to reinstall the software driver for the sound card. Usually, a virus/mal/ad/spy-ware will disable sound quite readily!

ADJUST THE VOLUME IN THE ICON ON THE START BUTTON MENU

you need to install the sound driver in order to get the sound from your system.....once u format the harddrive, you need to install all the drivers ie in technical terms its called CVAN which is Chipset, Video, Audio & Network drivers.....go install them all from the cds of your hardware and enjoy the difference.....cheers!

Run the software that came witht he monitor, then check if you are sending the signal to the monitor and not your old soundcard.There should be

open "Open volume control" on the speaker icon in lower right corner of your screen.

click options/Properties

the "mixer device combo box" will give you all the options you can send the sound signal to, in my case realtek audio, webcam.

the acer LCD should be there, if not try to figure out why.

I dont have an acer monitor, but this should get you going in the right direction.
