HTC One X Audio Hiss

Seen quite a few topics on this, seems no one has a solution.
What I'm trying to accomplish with this is to see if EVERY HTC One X has this problem of a hissing noise in the background.
The hissing noise sounds somewhat like television white noise, and is apparent when playing music at low volume and during quiet parts of a song.
Testing Method:
i) Using headphones/earphones/whatever that plugs in the headphone port,
ii) Play music or other audio.
iii) Turn volume down to zero (0%)
iv) Listen for the noise.
Repeat method with no headphones i.e. with speaker, and put speaker up to your ear (very close). Try and listen for the noise.

my one x has the issue too.

As far as i know this is not an issue and it's normal, try doing the same thing with any other device and you will hear the same thing, may be hard to notice sometimes but it's there ( I didn't notice this on my HOX until i read your thread )

I do have this hiss on my one x.It can easily be heard when the music is stopped and this hiss continues for a small second!

It drives me mad as I tend to listen to music on lower volumes compared to others...

if it is for 2-3 seconds and then it stops, it's normal, not an issue, due to a low voltage signal the sound chip sends to audio device (whether that would be a simple earphone, or a full support Bluetooth audio kit) to announce that the sound broadcasting is finished... (fade out noise)

Same here.

At 0% volume mine does not hiss, however if I play a song then pause it there is a faint hiss for a second or two then it stops completely.

Here's another one, plug the charger in and here the buzzing/feedback through the earphones when charging...

No, the problem that I'm experiencing and trying to see if others experience is whether the hiss is happening DURING the music. I understand if you listen to music at above 50% you most likely will not hear it during the music.

Yes, I have got the same problem and it is caused by very poor SNR of One X DAC or analog circuit.
It is very annoying for me, as I use sensitive IEMs and my old HD2 has not got this issue at all - I just find hard to accept that I have to hear audio noise in 2012 flaghsip device. There are some workarounds possible that can POSSIBLY at least partially mitigate the problem:
1. Use less sensitive headphones
2. Use some kind of attenuator, like:
http://www.ebay.co.uk/itm/Sound-lev...13488602?pt=US_Headphones&hash=item1e6f218cda
and increase listening volume at the same time

Issue confirmed. Could not believe that in this day and age I am confronted with such an obvious hiss on this top-of-the-line HTC phone.
Coming from the S2, I have not been impressed with the quality of the One X. I like the screen though, when I can't see any yellow spots, that is.

Will an external DAC help with this problem, if even usable with a phone?
Sent from my HTC One X

I probably should have said in my original post but yes I have the issue and noticed it....
Alternative was to use Bluetooth, I personally might get an APT-X adaptor thats portable so I can connect to my home cinema system or car stereo through the jack input....

I wonder if there's any One X without this problem, such as newer batches etc

If you can feed it a digital signal, then yeah, by all means it would help. I've not looked into it, I dunno if it's possible.

about 3 peoples said there it is normal so why continue this ? lol it have everything that make music,sounds.. its normal due to low voltage to earphones and there is currently no technology that can stop this noise...

Larger sample size. And also speaker out has this problem, not just headphones. And why other phones don't have this problem?

cfm +1
using music app or tune in radio connecting to my cars aux in via 3.5mm connection cable to utilize audio device and loudspeakers in car, and it is even more noticeable.. (the sound is great though) also you hear hiss and noises as inerference effect from the the engine clearly in silence between track changes

I have it as well, but im pretty sure iv heard the exact same noise on most consumer devices ive had like my ipod and old s2.. didnt even think about it till i saw this thread.
If it bothers you that much just email htc and see what they say...

Poor Sound Quality

Ok, has anybody else noticed the poor sound quality when you playback music on your headset? There's a hiss and you sometimes here sounds break up. I noticed this last night while I was playing music. I didn't expect this on a premium device. Really disappointed, anybody know if this has been mentioned or is waiting to be fixed?

I don't have that issue but I use Google Music.

Doesnt appear that anyone in the audio review thread are running i to this issue, may be a faulty unit worth getting fixed, or atleast try the audio on a store unit with your headphones and see how that goes.

I was listening on the earbuds it came with earlier and didn't notice anything when using Spotify. Just now used it with my Audio Technica ATH-M50s and still no hissing or breaking up with Spotify. Spotify and Google Music is all I use and I stream all of my music. Not sure if that makes a difference.

Same as me. I just stream all my music with Spotify. No problems here, audio is fantastic and crisp.
Sorry to hear you're having issues.

Purexaudio works on ARHD Rom, and makes my Westones worth the bucks spent. Greatly improved the audio without BoomSound enabled.
You can find it on the one x thread.

I think I've found the problem, it happens on low volume, turn Boomsound off when you're listening to music at low levels, i.e. at sleeping time.

Heya, sorry if my question is a bit irrelevant to the audio quality of the phone, but do the audio volume controls on your headphones work on the m8?
I've tried using my apple earbuds controls on my M7, and only the play/pause button works...nothing more. Did they change that for the m8?
Thanks.

Could be that it's incompatible to iPhone controls. I've not used them.

I've used the earphones that came with the samsung galaxy note 2 (since my brother has them) on the M7, and its not working as well.
Why would HTC do such a thing

My handset speakers sound great but I notice that when I plug my auxiliary cord in the headphone jack of my phone to input to my car stereo - it sounds terrible, all distorted and stuff. I have the same 320kbps mp3 file on my mp3 player also on my SD card of my phone so I know the file is good. I also have a high quality aux cord so I K own it's not that either. When I play the same song from my mp3 player w/my aux cord to my car stereo rather than my phone w/my aux cord to my car stereo, it sounds great. Phone output via aux cable sounds like crap. Is this cuz of boom sound and if so, how do I shut it off?

You can shut off boomsound in settings when the aux cord is connected, I also find that visualizer increases distortions when playing certain files so try not to have the music player on visualizer when playing through the headphone jack.

Phone beeps with minijack

I have the same issue. With my custom headphones I hear a lot of hum noice during music play but with other headphones it's ok so I think that problem is with impedance. 25 ohms for custom (1964Qi) and 15 ohms Sony MH1C. If anyone can test it or has idea how to solve it?

Today I tested 2 LG g3 and 1 LG G2. All off the phones do have this issue we have. But only with my bose. Testet nye pair of headphones and same problem so our phone is OK and I am buying a new headset possibly wireless

C'mon I don't think that problem is in my 500$ headphones. It looks like some incompatibility but needs to be investigated somehow. Some portable headamp or DAC can help as I need good headphones

The problem is in the LG phones not just ours but all LG phones. Maybe it is software related?

It's possibly hardware related and just poor isolation of the circuits used for audio on the phone. I hear the two beeps on earphones and headphones but little/no static.

It's cheaper. PC motherboards are only _just_ starting to get isolated audio as a standard feature and think how long they've been around. To isolate components from other parts you need more room as well, something phones don't have.

Try pulling it in and out a few times and then wrot wipe the connector. I've read some making this work. Seems to be an oil or something in there.
Update. This did the trick for me!

Anyone hearing a noisy headphone jack?

I often plug my phone in to my stereo system using the headphone jack.
I've noticed that when the phone is not actually playing something I can hear some little crackles and occasionally some buzzes.
I've tried it plugged in to several sources and they all show the same bahaviour, so it's not the stereo, it's the phone.

Did you try all of them with the same wire? That could be the cause of the noise.
I've only tried mine with a wired headset and didn't notice any noise.

Yes, different wires

Good question. Yes, I tried two different 1/4 inch to RCA cables and also my 1/4 inch to cassette adapter. Also tried a different phone with the same cables and had silence.

This only happens to me when I plug my AUX cable in my car into my 5X, but it doesn't happen when I put my headphones into it.

I can hear an audible noise every few seconds when I have my headphones on and nothing playing on the phone.. No issues with those headphones plugged into other devices.
Also, my output volume is low. Need to crank my stereo up in my truck when this is connected via aux. Full volume on both the phone and truck is equal to about half when using my nexus 6.. Huge disappointment.

I have this same issue and I've also noticed that the device does not get loud enough when plugged into my cars stereo on my S5 I can the volume all the way up on the phone and keep the stereo at 25 and it would be loud enough for me but now with my 5x I have the phones volume all the way up and the stereo set at 38 "witch is the max volume for the system" and I'm still left sometimes with wanting the music to be louder so hopefully this can be fixed with a software update

Same experience here with the volume in my truck compared to my old phones

I've noticed this happening on my phone as well. It does it with two different aux cables (not when I plug in headphones, though, oddly). My roommate's 5x does it, too. Turning the screen on stops the crackling. I recorded a video of it (I apparently can't post outside links so you'll have to build the url yourself): youtube . com/watch?v=-RObC7bZcQs
The volume seems fine though.
Edit: I received a replacement phone yesterday, and it has this issue as well.

Yes, I can report the exact same behaviour.
If I put a different phone on the exact same setup, there is complete silence when that phone is not playing back audio.

Anyone find a solution to this?

I get a pop in the silent gap between every song on Pandora. I am using a Bose Q15 noise cancelling headphones and nexus 5x with marshmellow. With new batteries in the headphones and low volume 15%..

I've been noticing the same issue. It only happens when no audio is playing back and the screen is locked. When I unlock the device there's no popping until it locks again.

Ditto. Getting pretty frustrated with so many accumulating little annoyances on Nexus phones.

Music stops playing and google voice kicks in when I touch the headphone cable

I have a Samsung Galaxy A3 2016 and I have had this problem for about a year. When the headphone cable is moved or touched the music stops and google voice starts. I tought it was a problem with my headphones but I've changed like 3-4 pairs of headphones and the problem still occurs. The problem only occurs when the headphones are plugged in. Anyone has a solution for this problem? Thanks in advance!

it looks like the brass inside your audio port is bent.

Reconnect, and test, until it doesn't.
Try cables with 4 pins.

you have to open the phone. u need a (-) screwdriver, but the best way is soldering it. u just need a jack socket ( u can use from any device which have audio jack ) , or u can buy it, its cheap. less than 2 dollar
