Sounds are turned on in Vista yet they don't play. What setting could I
have missed and what can cause sounds to stop playing? The speakers
work fine. All connections are secure.
I had it twice where I had lost sound on Vista.
One time it happened, because I went into the sound properties and some
how changed the output to external speakers. I had to change it back to
head phones as the output so that the laptop could play DVD movies and
other general things Vista did in using sound.
It took me sometime to figure out what I had did to cause the problem.
The second time is when I allowed a Windows Update to update the sound
card's driver thinking that would be ok to do, and it took out the sound.
I had to go to Device Manger and Roll Back to the previous driver for
the sound card. I should have known better to allow MS to have anything
to do with updating a device's driver, a no no.
