K guys, just got my 5720 and i got the Hiss...

It's ok, I can handle it.. but

Is there any way of turning around it? Turning it off completely or even just making it less hearable?

apreciated

If you look through this support forum there are already a few posts regarding the hissing problem. You can go read them to figure out what they did and how but off the top of my head they did stuff like making one of the other inputs the headphone one, turned of the some of the stuff near it and what not. Look around you'll see it

My experience with the noise was due to the other inputs (rear blue, black, mic in, etc.) I muted them via windows volume control, and BOOM! Great sound. If just listening to headphones, there is no need for the other ports to be on, so mute them. Less interference.

Right click your realtek icon in the system tray and select volume control. Then select options, properties. Playback should be selected by default, then go down and select all the boxes to display all volume properties. click ok. You should then check advanced onder options. You should have a wide volume control screen with all of your ports. Mute all but Master, Wave and Front.

A Sager technician I spoke with personally suggested turning off the IR port if you aren't using it. I turned off my IR and serial port together in BIOS but you can simply disable it within hardware manager. I don't think it helps much but the suggestion came directly from Sager.

Sager spent days with my computer trying to fix the hiss (though they would never tell me what they did try or what solutions they considered "unreasonable") and returned it to me the same as before. The IR port is not responsible for the hiss, but for the chirping.

Yes, muting some of the other inputs does reduce the hiss, but it does not remove it. And the hiss will still be painfully loud on a good pair of headphones. You can even mute everything on your computer and the hiss is still there.

The problem, as I've written many times before, is that the headphone jack is overamplified and the hiss is just a natural result. Imagine turning CD player volume down to 2% and jacking up the speakers to 100%. What do you get? A HISS! The same thing happens on nearly all of the Sager notebooks. Headphones plugged into the headphone jack are extremely overamplified. But the other audio jacks are fine.

The only reasonable workaround is to get a dead audio plug, stick that in the green headphone jack (to mute the built-in speakers), and then use Realtek HD Audio panel to remap a different audio jack as the headphones.

muting the Aux alone removed the hiss by 80% and with the line-in another 12%..i think i need to disable the IR..will check later on cause currently i am swearing to find the right day to clean the heatsink cause i cant play anything as it reaches cpu threshold easily :/

The IR port disabled did remove some of the remaning hiss but what its left is because of over amplification :/

SInce we are talking about the sound quality:

Is it just me (or my specific 5720) or the sound card distorts the sound a little??

Although the sound is good enough to play games on it, I can't stand listening to music, either on earphones or in the built-in speakers: the voice is often distorted (specially female voice) as if you screwed the equalizer... And yes, I have set the "enviroment" to "none" (which makes it worse) and then to "padded room" (which has the least amount of distortion) and turned off the equalizer. Yet, I get better sound from WMP in my PDA than I get from this laptop.

Do you guys also noticed this problem???

Reaches the CPU threshold? You may have a different problem regarding that. Some early purchasers (like me) received their Sager 5720s with a small piece of plastic tape between the heatsink and CPU. This strip is to protect the thermal paste, but it was never removed. My first Sager 5720 had this still on and it would overheat very quickly.

Because I suspected permanent heat damage, and at the suggestion of others, I had my whole notebook replaced (but I swapped the hard drives).This could be your problem too regarding the CPU heat.

hmm will check the heatsink later on..the thing is this: i have 2 spare slots: for a smaller heatsink and a fan and they are covered by a black plastic box thingy..i will ask the supplier if it is possible to attach the extended heatsink version :/ current idle = 68C and load = 75+C which results in the CPU slowdown and FPS drops
