I bought a new Dell Dimension E521 computer about 2 weeks ago with Vista
Home Premium on it.
The sound card is on board and is a Sigma Tel High Definition Audio Codec.
(Well that's what it says on my speaker icon.)
A few days after using the computer, I noticed I lost my sound so I called
Dell tech and I don't think they found anything wrong. After being on the
phone with them for quite some time, he told me to reboot my computer. In
doing this, I had my sound back so I figured all was fine.
A few days later, I lost my sound again but didn't call Dell. I just
rebooted and got my sound back. After the second time I lost sound, I did
receive a message that there were new sound drivers
so I installed them and
hoped this would stop this no sound from happening again but it didn't.
I've lost sound two more times. I'm not sure what I'm doing or what I've
done when the sound goes. I don't always realize it when it first happens
since not everything you do on the computer gives you a sound but each time
I lose the sound, all I have to do is reboot and it's back.
This is not normal and I don't know if it's a Vista problem, or a problem
with my Dell computer.
Before I try calling Dell, I thought I'd see if anyone here has any ideas.
And one more thing. This happened this morning when I first turned on my
computer, before I did anything on the computer.
I booted it up and walked away to do something. When I came back I had an
error saying my slide show screen saver couldn't start. I then clicked on my
mail and realized there was no bell when my e-mails came in which meant I
had no sound so I rebooted, and got the sound back.
Could the slideshow screen saver be causing this? That's the only connection
to the problem I know about.
