Acer Aspire Z5101

I am working on an Acer Aspire Z5101. I have restored factory settings however I can't get the front speakers to work. The earphones will work but will not switch between on board speakers when unplugged. This machine has Realtek Audio Manager and the default settings are there. Please tell me how to set up this sound system.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The internal connectors may not be making good contact when you remove the earphones.  If there is oxidation, the circuit for the speakers is not engaged.  Try wiggling the earphone jack and moving it around to clean the surface.  Since the earphones work, I think the drivers are correctly set up and it's just a matter of making the switch to the speakers work.

I tried that but it did not work. The front speakers do not work even without the earphones plugged in. Even on startup the speakers do not work. I know they work because they were working before the reload.

were the speakers working before?  otherwise, you just may have  bad speakers

Ok I downloaded the audio driver recommended and I now have front speakers. However now my earphones will not work. So I know the front speakers are working. Please let me know where to go from here.
lauchangkwangCommented:
first, make sure you plug into the correct hole. if still cannot, try to go control panel uninstall all the audio driver, restart, reinstall the driver, it might be some conflict for the driver.

what OS is this?
dbarbeeAuthor Commented:
Windows 7

is there a software installed (Realtek maybe?) look in it's settings
it looks like the speakers and earphones use a different output
i suppose you use the green port?
dbarbeeAuthor Commented:
I checked the Realtek software and the speakers and earphones are both using the green port.  If I get the speakers working, then the earphones quit.  If I get the earphones working, the speakers quit.  I am at a lost as to what else to try.
nobusCommented:
did it ever work normally?  if not, maybe time for a warrant y repalcement
it has the dolby surround theatre software? should be easy to use
CallandorCommented:
Both are using the green port?  That's for headphones or speakers, so it should work, if they are standard.  What model are the headphones and speakers?  There might be something about them that would reveal a clue, such as the impedance.

Computer picking up left rear jack in Realtek audio manager.  No rear jack available.  How do I remove that jack from the Realtek audio manager?
CallandorCommented:
> left rear jack

That sounds like a multichannel sound setup.  Try configuring the sound output for stereo.
