It shows that i can change all the channels, volume, shows the clock, etc. Problem is that there IS NO SOUND coming out of the speakers. What could be the problem

Check the speaker wires maybe they have worked loose. And speakers themselves as they may blown. Do you have an amp if so check its fuse. Also check for inoperative interior lights, lighter, and horn. One of these circuits will power the radio's memory circuit. Some radio models will appear to work normally but have no sound if the memory fuse is blown. The clue is the clock will reset to 12:00 each time you turn on the ignition switch.

Check to see if you a speaker icon in the lower r/h side of the task-bar down by the clock.
If the icon is not there right click on a blank area of the task-bar and left click 'properties'
Left click 'customize'
Scroll down to 'Volume' and select 'Show icon and notifications "
Click 'OK'
Close the 2 properties pop-ups.
Right click on the speaker icon and select 'playback devices'
The 'sound' pop up will appear showing whatever you have connected ( speakers or headset etc)
Make sure the speakers are set as default if you have more than one sound device connected.
The speakers should have a green tick (check ) when they are ready to use
Right click on the speaker icon and select 'Open volume mixer"
Check that the volume slider is above 50% and the speakers are not muted (shown as a red no-entry sign on the speaker icons at the bottom of the sliders' If muted click on the slider speaker icon.
Right click on the speaker icon and select 'playback devices' Put the cursor on the blue graph to the right of the icon, right click and select 'test' All being well the computer speakers will respond.

Maybe the speaker wiring...

Are on Windows 8 or an older OS. With Windows 8 Silverlight probably has it own volume control. Silverlight is the API used by Netflix to access you systems audio and video devices. If YouTube is OK (since it uses Flash and not Silverlight) then you have isolated the problem to it being Silverlight. However, this assumes the sound work normally for all applications and the OS. Of course, I once had a loose speaker wire on my center channel and some show were missing dialogue depending on how they were mixed so anything is possible but you never mentioned anything else being a problem.

Click the link below for manual pages I mention to make changes:

Most dialog sound comes from the center channel / speaker. If not working correctly, it make become difficult to hear people talking especially if there is a lot of other sound going on in movies and some music, too.

Check and adjust the volume level for the center channel or speaker. Check page 8 of the manual to learn how to use the remote to change the volume level of individual channels or speakers.

If you want, you may find it is a good idea to check page 17 to esablish correct volume levels for each channel by runnijng the set up with the microphone. This will allow the system to be "calibrated" for the room. This is a very important step in "getting the sound right".

If none of these suggestions work, you may have a problem with the center speaker itself - or with the amplifier for the center channel.

I hope this helps & good luck!

Check the speaker connections for the center channel. Page 6 shows the location on the rear of the amplifier - but check the speaker itself first as it is easier to get to and the rear of the amp is less likely to be distrubed and have a poor connection.

Hey ajn1n1 we need to fine where the tinnyness is coming from Lets do a test shall we,

hook up your voice matched polks to your front left and right speaker outputs on your amp to see how they sound as mains. if you hear tinny then its the speakers. sometimes speaker need to be broken in a bit.

hook up your main front left and right speakers to your rear outputs. if you hear the tinnyness then its the output of that channel on the amp or a setting. Newer amps let you change speaker sizes in the menu so that it can change over the crossover for that channel.

main board problem...check you wranty info...

Was the sound working beforehand?
First off try to find a continual source for sound like a music file or movie etc...something that can play while you tweak settings.
As the sound is playing(Make sure the program that is playing the sound file has the volume up, check your Advanced Volume settings by double-clicking your sound icon in the bottom right corner of your screen by your clock. Make sure the sound is set and none of the channels are muted. Next check the volume knob on your speaker and make sure that is turned up. Lastly make sure the speakers are securely connected to the PC in back (follow the cord). The cords are usually color coded, make sure it's plugged into the correct hole.
Good luck!

This is not a problem, this means that your system is working. Polar Express was recorded in Surround Sound with separate tracks for each speaker channel. In most movies you will find that the rear speakers will only play certain sound effects so that it appears they are coming from behind you (gun shot, train, fireworks). Most of the diaglouge will come through the center channel and music/effects through the front left and right, with bass coming from the subwoofer.

Now, you can still hear more from the rear speakers if you like this enveloping effect, or if you like your music coming from all directions. There are Sound Effects options to have the front and back speakers always playing the front track, there is Dolby Pro Logic II that turns stereo sounds (like many TV shows) automatically into 5.1 Surround Sound, and you can also individually change the volume of each speaker.

These are all explained on page 29 of your owner's manual under Sound Options. If you need specific button to button help, let me kow.

it can be due to faulty earphones or due to the connector and it has a wireless out do check for that if it is enabled u wont hear sound through the speaker
