Upgrade to the latest BIOS and audio driver.

Dilbatt,

I have already upgraded to the lastest BIOS and Audio driver. I stated that in the previous post. Is there anyone from Dell in here? Should I have you send me a new speakers?

My apologies!  I didn't see that you had upgraded.  So, I am curious about the hiss.  Assuming there is no sound playing, does the hiss get worse as the volume increases, or does the hiss stay constant at the same level no matter what the volume?

Yes, I have the same problem! A constant noise with latest BIOS, Sigmatel or Intel drivers, and a left channel haz much more distortion then right. Some times it can go away for 20-40 minutes (when laptop is working more than 4 hours).

Edvil:

Although muting the speakers seems to prevents it, does reducing or increasing the volume reduce or increase the volume of the hissing noise? Try connecting a pair of external speakers or headphones. Can the hissing be heard from these as well?

 

First, thanks to everyone that has replied to my post. It's appreciated.

Dilbatt and Rance, increasing or decreasing the volume does not seem to affect the hiss. However, when I open new applications or windows it will fluctuate a little. Also, I have tried headsets and the hiss is even more apparent. So, I don't think it's the speakers.

Nautis, I have tried the intel driver and I still get the hiss but it is not as loud. I think the driver just kind of mutes it.

DimitryM, I spoke with Dell and they want to replace the audio controller and the speakers for good measure. So, I'm waiting for the box and the waybill to come so I can ship it to the local depot. If that fixes it I'll let you know so you may do the same if you wish.

Again, thanks everyone for your input.

Edvil, I spoke to Dell (French) and they decided to change (!!!) my keyboard!!
I have no comments.

I will lock up that Dell technician for 10 hours in my office to listen to that loud noise from laptop.
It's sounds like FM-tuner interference, when it tunet to nothing or when it's receiving a very poor signal.
:(

I have the motherboard replaced, now everything is OK.

I have the same problem . . . .  is there a solution?

what I did to remove the hiss is drag the cd player volume down to almost muted, it seemes to come from cd player interferance or something.
