Hiss noise on phone speaker and headphones - HTC Desire X

Hello,
I just got my desire x. It is a good phone for the money.
But I have a problem with the phone speaker (front one) and headphones.
In both cases when sound is played I can hear on the background a constant hiss noise (static noise).
Is this normal to this phone or I got a defective one?
Before this phone I had LG P500 that also had this background hiss noise.

I don't have that sound, I think you got a wrong device? Or maybe it's the sound quality.

every time the speaker or the headphones get signal I heaer the hiss noise. it is a hardware problem.
when I searched on google I found out that one x user have the same problem.
how you can detect the hiss noise:
Play through the headphones a song and pause it, for a few seconds you should hear the hiss.
Anyone else?

---

I've noticed this noise too...
It seems to be a hardware issue, but since it's not very annoying, I don't plan (for the time being) on sending it for RMA.

Mine does the same thing; it's a bit disheartening to see my budget MP3 player outperform the Desire X on noise level and frequency response.

It's certainly not Desire X -specific; my previous phone (a ZTE Blade) had it too, albeit at a much, much lower level. My wife's Nook Tablet does it, too; apparently sound quality is allowed to slip on budget devices

Not desire x specific I think, mine is completely hiss-free ! Take it back to the store for a check I say

Recently got DX and even i have the hiss sound. When i play the song through any player and take the volume to zero, the hiss sound is there. And when i press stop, the hiss sound stays for 5 seconds every time then goes...
i dont think the issue is hardware related. at least lets hope a future update would solve the issue software wise..

this problem will probably annoy some people who are keen on every bit of treble sound and quality. this annoys me more cos i do electronics and know so much about sound and dB.
to offer some kind of comfort to those facing the problem watch this video. but it does not isolate the fact only some DX are having the problem. and to those that dont have the problem please watch this video around 3.27 and exactly at 3.30 you will hear the low hiss sound some of us are experiencing

Well I do wonder if the people whose DX don't seem to have this issue maybe are just listening for the wrong thing I must point out that I haven't used the shipped headphones yet; I've just used my regular headphones.
And before anyone goes off a tangent: I'm not an audiophile, far from it. My case is not made from piano or violin lacquer

absolutely. maybe those who dont think they have the problem should check out the youtube video i have posted and listen to the sound at time 3.27 and around 3.30 the hiss sound will be there...
the hardware or software problems seems inevitable for those who buy the first batch of a new phone...whoever the manufacturer is.

Thanks for pointing out what to listen for.. I think I heard what you guys are referring to. Do you think it is there in the background when playing music at a (minimal) volume ?

yeah man. the faint hiss sound (white noise actually) is there at volume level zero even. its much noticeable when we reduce the volume of a song to 0. but if u stop the sound suddenly while keeping your ear on the speaker piece...you will notice complete silence just after 4-5 seconds...before that you will hear something bzzzzz....

I just found out something weird.
When I listen to music with my hands free or an other pair of Sennheiser earphones, the hiss sound is something more than noticeable, even if I mute the sound while the music is playing on the background. Also, when talking on the phone (with or without earphones) I can still hear the sound. Just like it was mentioned on the previous posts.
But I tested it with a pair of headphones (AKG 172) that I use for my PC, and the sound was crystal clear! No hiss noise at all, no matter what I did. Listening to music, muting the sound (while mp3's still playing), talking to others on the phone. Everyone was just fine, no hiss noises or other disturbing stuff.

That's what I heard, takes a couple of seconds and then everything goes completely quiet. In my case, it's pretty faint though. I'm just wondering if the noise is present when playing music at any volume ? Maybe some people here can record of the headphone jack and check the clip in audio software lol (if anyone has time)

unfortunately the hiss noise is present even when playing music. I listened to a quiet passage and is there, it was not from the track. the hiss is also present during calls.
Anyhow the sound quality in desire x is poor and the beats logo is just marketing.

i checked my HD2 for the first time since i saw this topic and noticed this in my DX. to my surprise even the HD2 has the same symptoms and the white noise turns to complete silence just after 4-5 seconds. its given me some comfort actually

I'm new around here but I thought I'd weigh in with my findings on this (hi everyone!)
I just got a Desire X and notice the exact same "hissing" problem as described here, it is most noticable when using headphones but it happens when using the earpiece and speakerphone. Barley noticable when using speakerphone but it's still there.
I was curious so I pulled out my old Desire S and tried to reproduce it, the old model has no sign of it at all.
Interestingly enough I have a cheap-ish Toshiba laptop and it does the exact same thing when using headphones; play something at low volume and there is a hiss noise, hit mute and then the noise stops after a few seconds.
I have been in contact with HTC before I found this thread and asked them if this is a fault or something that all of the Desire X phones do, they responded with:
We appreciate your prompt reply. Please be advised that we based facts on what has been reported to us. We cannot attest to the authenticity of the different opinions and customers experiences that are found on different blog sites.
As of the current time, we are investigating the possible cause of this issue. If the problem persists, please send your device to your dealer to have it physically assessed.

I never mentioned anything about findings on the internet, i just stated the fault and asked if they all did it.
Does anyone here have a custom ROM on their DX and still have the same problem?
EDIT:
Also thought I'd mention that the hiss noise is the same volume regardless of the volume level, increasing the volume during a call or while listening to music does not make the hiss louder

Wow. What an attitude. Seems like someone is pissed at forums or blogs for finding faults that exists only . Talk about customer care!!! Jeez
As for nathb...thankx for posting their reply. Seems like they do read a lot around here for "speculations". Haha.

They did numerous times make a point of the fact that they are investigating the cause though!
Maybe that means a solution is in sight for DX (and oneX as well?) users. I am keeping my hopes up because I really like the phone otherwise.
However my knowledge of what causes these sort of problems leads me to think that it is hardware-based and the only way to fix it will probably result in a noticable drop in audio quality from the phone

Guys can anyone test the device with a pair of headphones, just as I mentioned six posts above?
I tested it again, but this time with my friend's headphones, and again, the sound was totally clear, with no hiss noise... I really find it strange.

EDIT: and now its fine with my htc headphones too, playing music through poweramp first and then htc music player.
what the heck is going on...
