|Search the forum: either the wireless or the irda is to blame for the hiss ...
The IrDA only solves the squeeking noise, not the hiss.
Since maybe some people's ears have been damaged by earbuds,
check this. When you plug headphones into the headphone jack, do you have to drop the volume really low?
The problem seems to be related to only the headphone jack being overamplified. It's like jacking up speaker volume but not increasing the source's output volume.
|Zero Hiss on mine as well, so were 3 for 3 in this topic.
But I count as 2 because I've had two 5720s thus far and both had the exact same hiss/overamplification problem.
|I'm pretty sure you can remap the 3 audio ports [1 right side, 2 back] to whatever you want them to be using the software installed. From what i heard though, if you remap the headphoens [front channel] to be anything else, it will NOT deactivate built-in speakers when you use it. but i havent tested that so i could be wrong.
That is correct. Remapping any of the other three ports (through Realtek HD Audio Manager) to a headphone jack produces wonderful sound (for a built-in audio chip) with NO HISS, but doing so does not disable the internal speakers (which is also weird in itself). It is only the headphone jack that produces the hiss, which is unacceptable for any computer costing more than $1,000.
Sager has taken way to long to do anything about this issue. In hopes that it was just a fluke in the two 5720s that I've had thus far, and the many others that other people have reported, I'd like to try getting my notebook replaced again.
But the problem would seem
to be fixable with a simple firmware patch. That is, if the overamplification is a result of something in the firmware.
Doc_Simple has also reported the same hiss in his reviews of the 5700 series.
