Solved my external speaker is not working on windows 7

[digikill87]

i had a ubuntu on my laptop and windows 7
last know the external speaker on both OS are working well
but now the Windows 7 can't seems play any sound on the external (the internal laptop speaker is working, yes)
and in ubuntu is just working as well
does the ubuntu affects something on the external speaker? because i did installed a sound equalizer in ubuntu and now i delete it but still the same in windows 7

The Ubuntu will not affect Windows.

With some sound chips, there are options to mute the headphone jack. Check your system for any possible options such as this.
