I recently bought a vostro a840..did a clean installation of windows 7. Since the separate drivers for windows 7 arnt out yet..i installed the Vista drivers that came with the cd. Everythings working fine other than the sound from the laptop that is really choppy with a lot of breaks. Tried everything in vain including the WIFI and dell diagnostics. In no state of playing music or even watching a movie. The sounds ok when using a headphone...its the internal speakers.
Audio driver -conexant hd audio 221.
Chipset - Intel 965
Processor - intel core2duo @ 1.63GHZ
Ram - 3gb
Os- windows 7
Any help's gona be much much APPRECIATED!!
Sorry I did not reply because I do not know the answer-- I can't think of a cause to have noise in the speakers but not headphones -- and because I didn't understand some of your post.

I don't understand what you mean by trying the WIFI, and you didn't give the results of the tests. Presumably you did them with headphones and again without, but with what result?
The only thing I can think of is to install the generic driver as explained in section 6 of The Audio Driver FAQ. If you get the same result with it installed then you might have a hardware problem.

Hey thans for replying jim. By the wifi i meant that in some forums i came across users who stated their wifi devices were interfering with their sound from the laptop. so what i tried was changing the band..(a.b.g)..even the drivers..but to no avail. Even tried different drivers for the sound card (conexant smart audio 221) Done everything including the use of the generic windows 7 sound driver...no change in the choppy sound..
The funny thing is the sound is normal while using headphones.
In a fix..any ideas?
The fact it does not happen through the headphones and that changing drivers does not fix it suggests that there is something wrong with the speakers that Dell should repair under warranty.

The test for the wireless is to turn if off completely to see whether or not the noise ceases. However if it was the wireless you would hear the noise through the headphones as well as the speakers.
I might have been the one who suggested you to disable the
wireless adapter .But as far as I remember you complained about noise
in your headphones AND the speakers.
The fact that the sound from
your headphones is fine and the noise occurs only through your speakers
means that something might be wrong either with the amplifier or the
speakers themselves as "Jimco" rightly pointed out.Usually the speakers
share the same amplifier output with the headphones(when you plug in
the headphone a mechanical switch disconnects the speakers) - so it's
highly likely the speaker system.I once had a problem with integrated
speakers on an external TFT-panel.When I opened the panel to check the
amplifier I was surprised that the output signal was absolutely fine.So I
removed the speakers and when I did so I found a loose screw(!)
caught between the membrane of the speaker and the panel....the bouncing
srew caused the crackling noise....you see there are a lot of options that
can create problems.
Use the speaker balance option in your software (if available ) to find out if only one speaker causes the problem.
But I guess you will have to contact Dell
Yeah most probably theres a problem with the speaker system itself...while the sound through the headphones are absolutely fine. Tried switiching off the wireless but to no avail...
Guess ill have to give it back to dell..( and pray it's a loose screw! lol)
Thanks a lot for helping out guys
