I lost my volume all else is good

1 Make sure that your audio cables are plugged in properly to the correct ports if your audio is distorted or noisy. Every cable should be inserted completely. If you still encounter bad audio, replace the cable and then attempt to use a different device with the old cable. This will help you pinpoint the source of the bad audio problem.

2 Use the "Volume up" button on the remote or TV buttons panel to turn up the TV audio volume if the volume is quiet. If the volume is still quiet, check to see if your audio source device has volume settings. If it does, turn the up the volume on your device (see your device documentation if you need help with this).

3 Press the "Mute" button on your remote control to disable the mute function if you can't hear any audio. Once disabled, press and hold the "Volume up" button on your remote control to turn up the volume. If there is still no audio, press the "Menu" button on your remote control, select the "Audio" menu, and ensure that the "TV Speakers" are set to "On." If you are still not having any luck and are using the built-in TV tuner, open "MTS Audio" inside the "Tuner" menu and make sure it is set to "Stereo/English." If there is still no audio, verify that all your audio cables (including the antenna cable if you are using one) are plugged securely into the proper ports on your TV and audio source device (if applicable). If you are using an antenna, reposition it to a clear, open area; preferably near a window. If your audio source device has audio settings, check to make sure they are set the way they should be (see device documentation).

The VM9312 has a volume knob on the unit's faceplate. Just rotate the knob on the left (a little below the optical disc D slot) clockwise to increase the volume. Turn it the opposite way to lower the volume. (If you have the knob set to the maximum volume and then lowered the volume with the remote, you may need to reset the unit; see below.) If you push in and release on this button, you press Enter or confirm a setting when you are in any audio settings menu.

If the volume control isn't working, check if the mute is on. Press once to toggle the Mute. The mute button is just below and near the right side of the optical drive slot.

If you still can't change the volume, check if you have the wiring correct and no shorted wires. Look for damage at the speakers (or evidence of mice chewing on the wires). Also check your audio balance. See the manual page 12 here: http://www.voxxintlcorp.com/docs/common/VM9312/VM9312_OM.pdf . You may also want to try a system reset. (Press and hold the reset button for a few seconds by using the tip of a ballpoint pen in the little opening at the lower right hand side of the faceplate.)

I hope this helps.

hope this helps don

Check if the cable's are plugged in their correct component socket's and try using and Audio manager that help you manage how many speakers you have(Also availible in the sound and Audio Devices menu)

Try this, go to control panel, sounds and audio devices, select audio tab and make sure the sound playback and record are set to your sound card.
I hope this helps.
I have another idea but try this one first and let us know if it works.
Good Luck.
