@Nirvanium17: As far as I know, The hissing sound that is "normal" is caused by the software part of the sound system continuing to output sound right after the "screen tap" sound. Try it with headphones as well. If it plays in your headphones you know it's a software thing. Also, see if it goes away if you turn off screen tap sounds in the control panel.

@NSchively: plug in some headphones, turn up the sound to moderately loud, turn on screen taps in control panel, sit in a quiet room and tap the screen. Now tell me if you hear a very faint hissing...

Of course if I'm wrong about all this, then Nirvanium17 and I have the same problem...

Yes, it's a software issue.

I haven't had system sounds on for a little while, so I don't recall. It's too noisy in here detect hiss at anything much further than a few inches away from the screen.

But, again, hiss when playing system sounds is normal. You could just turn off the keypress/screentap sounds if you don't want to hear it anymore.

So what you meant was the barely audible sound that is only detectable when you put your ear next to the speaker? Why didn't you say so? Then, yes, I think that is normal and as the good Dr. noted, likely a function of the sound files; I remember something similar on early sound files on my old windows pc's.

if it isn't noticeable under normal operation, don't worry about it. As my childhood dentist told me when I confessed my teeth felt loose when I bit my blanket and dangled from my top bunk bed, "Well, don't do that."

When I put my ear up to the speeaker while typing this - a true contortionist act - I can hear it all the while while typing, for about 4sec after I'm done. But as you noted, you can't hear it when you're sitting upright. I think it's a function of the software and not any big hardware problem.

I believe it actually has to do with the sound output (gstreamer?) rather than the files themselves, but, basically, yeah.

I think it's just noise produced by the amplifier. A few seconds after sound output stops, it seems to be turned off again. So, I don't think software can do much about it other than maybe turn of the amplifier sooner. But this could lead to other problems like clicking.

In my experience it's normal, but I need to be using 'phones to hear it. I'm guessing the sound system powers up to play the sound then hangs around on power for a few secs more in case another sound is needed.

mine has had this "bug" the whole time Ive had it, its most annoying when using headphones, and is just about unnoticeable in some situations, Id hope it would get fixed someday...

I just got mine and I haven't had any hissing things, any sound playing though pauses when I click the internet, but fixes it self, no real hissing though

I think the sound is normal. You hear it when browsing the web and it's because of the WIFI radio that interfere with the physical drivers in your headphones and device speakers.

I don't know if you own a cell phone but when you are receiving phone calls and the phone is near speakers or a CRT monitor, the speakers tend to hiss and monitor image will become distorted. I think this phenomenon is caused by EM interference. It is the same idea for the N800.
