The noise is really quite significant, it makes listening to music over headphones pretty bad below half volume.

NFC was already turned off, but thanks for the advice anyway.

I've noticed the hissing when I use the camera to video something

I'm waiting for a replacement but now wonder if all phones are affected by the problem
[One (M7) Q&A, Help & Troubleshooting] Jme369:
I doubt it, this is the only thread describing this problem so far. Return it is... Love the phone but am hating the build quality.
[One (M7) Q&A, Help & Troubleshooting] cobbcobbdavid:
I think it might relate to Enable Beats sound. However, customer service told me HTC is working on this and will fix in SW.;)
[One (M7) Q&A, Help & Troubleshooting] Mr Sliff:
It is the beats audio. Turn it off and the hiss is greatly reduced.
[One (M7) Q&A, Help & Troubleshooting] Jme369:
Beats audio seems to make no difference, have a replacement coming tomorrow so will be able to see whether it is a manufacturing fault or not.
[One (M7) Q&A, Help & Troubleshooting] Aziki:
I have this problem as well on my HTC One (Black).

It seems to be most noticeable on Youtube videos and games for me, disabling beats audio does seem to reduce the background noise / static but doesn't seem to get rid of it entirely, it also seems to happen no matter what you have the volume set to or if you are using headphones / the speakers.

I couldn't live with it and tried to get it replaced by phones4u but technical support said I would have to take it to a store and compare it with another HTC One, unfortunately no stores near me have any in stock so I am going to return it and wait for some of the kinks / build issues with the phone to be worked out.

In my experience from having the One since Friday, I would say it is a software issue rather than the hardware. I do get popping and bad hissing from the speakers at different frequencies, but if I turn off Beats Audio it is reduced drastically, although then you lose the nice bass and depth from the speakers. :( Hopefully it will be fixed in an update. I mostly notice it on YouTube videos or files with lower quality/bitrate.
[One (M7) Q&A, Help & Troubleshooting] Jme369:
Rescheduled my delivery for tomorrow but will update this thread, id be suprised if this is an issue common to all the handsets though as it's pretty unlivable for me and I would have guessed more people would have reported it.
[One (M7) Q&A, Help & Troubleshooting] Jme369:
Received the replacement, same issue with the audio. Could be either a software fault or a hardware fault common to the batch? Either way, the replacement I received has some awful build quality issues, gaps and an overhang in the metal. I like the phone but this is getting stupid, may just get an s4...
[One (M7) Q&A, Help & Troubleshooting] Aziki:
That sucks! :/

I was hoping you would come back saying your new phone is perfect and doesn't have the problem. It's weird that no one has come into this thread saying they don't have the problem, although only a handful of people have said they do.

It does seem like a software problem like you and a few other people have mentioned, considering sound is one of the main selling points of this phone you would have thought they wouldn't have shipped it with such an obvious flaw.

I'll be sending my phone back tomorrow and at this rate I'm not sure if I will be getting another one as the sound problem bugged the hell out of me for the short time I used it.

-Aziki
[One (M7) Q&A, Help & Troubleshooting] Jme369:
Phoned three and they were really apologetic, sending me a new phone that they will first inspect for build quality issues. I expect the audio issue will persist though. Phoned HTC to see if its a software issue or not (also reported the capacitive button issue) and a manager is going to phone me back at some point today or tomorrow. They have until the s4 release date to give me the phone I paid for or im jumping ship.... Good luck with your replacement :).
[One (M7) Q&A, Help & Troubleshooting] Matt:
The hissing is a known issue which only appears on some builds, I personally have no issue so it is hardware :)
[One (M7) Q&A, Help & Troubleshooting] Jme369:
What is the serial number of your device (the first 6 characters)? Would love to be able to track which build exactly has the issue.

Just to clarify, the hissing is most noticeable if you play a track at low volume through headphones. Is made worse with beats enabled, but still occurs without it on.
[One (M7) Q&A, Help & Troubleshooting] Matt:
Serial number is HT339W, so it was made on the 9th March 2013 in Taiwan. No hissing at all
[One (M7) Q&A, Help & Troubleshooting] Jme369:
HT33JW here, so 18th March in Taiwan
[One (M7) Q&A, Help & Troubleshooting] Aziki:
Considering you have a phone that was manufactured more recently it doesn't seem like it's something they have fixed, seems to be pot luck which is unfortunate.

Hopefully they get back to you soon so you can update the thread with more information as I would love to know exactly what the problem is before I decide if I'm going to get another HTC One ;p.

[One (M7) Q&A, Help & Troubleshooting] Jme369:
Had a manager from HTC phone me back, no known issues with the software so im gonna assume its a a hardware issue. Third handset being delivered on Monday, fingers crossed that it has no issues. If it does, Samsung it is...
[One (M7) Q&A, Help & Troubleshooting] Aziki:
I think it would have been better if it was a software problem as it could have been easily fixed with an update, it's odd that someone else in this thread was told by HTC it is a software issue and you were told something completely different.

I'm starting to seriously consider the S4 as well but the design is boring and it's over £100 more ;/.

Will be interesting to hear if your new phone has problems as well, it does seem to be pot luck really with this phone, even if you don't get one with this particular problem you could get one with poor build quality instead, bleh! ;p.

[One (M7) Q&A, Help & Troubleshooting] Aziki:
Hi,

Just wondering if you received your new HTC One and did you finally get one that doesn't have the hissing problem with the audio?

Thanks,

Aziki
[One (M7) Q&A, Help & Troubleshooting] Jme369:
Got another one today, hissing still present but I think through having three I know a bit more about it-

-Beats makes it alot worse.

-NFC makes it worse.

-VERY noticeable when replaying video through the phone.

-Other android devices seem to suffer from background noise issues IF you use decent headphones, therefore it is partially an android wide problem.

For those reasons im fairly sure its a software issue. I refuse to believe that ive had three handsets, all from different batches, that all contain the same defect. That said, my third handset it going back because of another issues- piss poor build quality (scratches, gaps, etc). If the next handset is without build quality issues ill keep it. If you can, compare your audio to another android phone's audio, with nfc and beats disabled. Lastly, i'd really reccomend three, theyve provided me with great service.
[One (M7) Q&A, Help & Troubleshooting] Aziki:
I still find it odd that one person has said they don't have the problem a can't hear any hissing, maybe they have poor hearing or something ;p.

I currently have a Galaxy S and I just tested it with headphones and I must admit when you hear the system sounds / notifications there is a slight hiss in the background if you really listen out for it but you can't really hear it when playing music. I can't hear the hissing from the speakers but that could just be because they are much quieter, not really sure.

It may be a software / android problem but it is definitely a lot more noticeable on the HTC One than on most other phones, (well I've only really listened to the audio on the Galaxy S, Galaxy S3 and HTC One) you have to really listen out for it, it's a shame because it really is hard to ignore once you notice it and it does take away something from the phone :/.

I'll probably wait another couple weeks until I another HTC One (still waiting on my refund from Phones4u anyway ;p), hopefully I'll be able to live with the hissing, it's just really annoying when you are playing a game that doesn't have constant sound (eg Dice with buddies) and you get a loud hiss when you click on a button or win a game, it definitely doesn't do that on my Galaxy S using the speakers.

-Aziki
[One (M7) Q&A, Help & Troubleshooting] Dwin-d:
I've got some slight hissing too with headphones. And I've got some with the speakers, which is way more pronounced when playing a video (there is some static noise), compared to playing music.

And do you guys hear some popping/clicking sound from the speakers every time the speakers go off (after a notification for example) ?
[One (M7) Q&A, Help & Troubleshooting] Jme369:
Yeah, thats part of the issue. I think its a common problem to all the devices though, possibly owing to how loud the speakers are in comparison to other phones but mostly because of beats, I think.
[One (M7) Q&A, Help & Troubleshooting] Matt:
My hearing is fine :p it doesn't hiss.
[One (M7) Q&A, Help & Troubleshooting] hmillhouse:
How likely is there to be a software fix I wonder? I see similar threads for the One X, but without much conclusion.

I'm debating returning an otherwise perfect One & sticking with S3.The pops and clicks annoy me, especially for notifications when the phone is already on silent... Why's the speaker being activated?
[One (M7) Q&A, Help & Troubleshooting] Aziki:
I guess you are extremely lucky then as pretty much every other person that has posted in this thread does have hissing coming from the speakers and when using headphones.

I really hope it is a software issue and can be fixed by an update but if it was you would have thought HTC would have at least acknowledged the problem instead of saying there is no known problems with the audio.

I just find it really odd that no review has mentioned this problem and they all rave about the audio quality on the One, oh well :/.

-Aziki
[One (M7) Q&A, Help & Troubleshooting] Fensy:
I was thinking just the same, I have just received the phone today and have no build issues at all and love the phone, however I do listen to music quietly on headphones and the first thing I noticed was the hissing and popping sound :(
[One (M7) Q&A, Help & Troubleshooting] omersak:
Tried playing audio over the headphone out at all volume levels below 50%, did not notice any hiss whatsoever. It might be because the impedance of my IEM is 55 ohms.

[One (M7) Q&A, Help & Troubleshooting] johnboywilson:
Add me to the list of hissing popping sound.

If I send my phone back do I get new one?

I also have an issue with Bluetooth sound. It sounds like a CD jumping when playing through my Bluetooth car radio.
[One (M7) Q&A, Help & Troubleshooting] h.han:
Yes, my black One received yesterday has the hissing noise especially when beats audio is enabled, same as my wife's silver One bought late March. I would think this is a software issue cos bests is software and it amplifies basically the noise.
[One (M7) Q&A, Help & Troubleshooting] tuscolavol:
What doesn't make sense to me is none of the reviews mentioned anything about hissing or popping. I'm holding off until I get answers. Too many folks complaining for me.

[One (M7) Q&A, Help & Troubleshooting] Paleryder:
I notice the hissing when in call and the other person speaks, I'm on my second phone and same thing. I hope they will bhave a fix for it. I really like the phone otherwise. My phone is right and no gaps our bad edges,you have any pics?
[One (M7) Q&A, Help & Troubleshooting] h.han:
I do hear the hissing noise when in phone call, but only for the first about 3 seconds, then I hear a noticeable pause for about 1/3 of a second, after it, all sound loud and clear no hissing.

This heappens regardless of beats turning on or off.
[One (M7) Q&A, Help & Troubleshooting] Aziki:
I received my second HTC One (Black) on the 19th of April and unfortunately it has exactly the same problem as the first, it is from a much more recent batch as well (April).

I get a loud hissing sound while watching youtube videos and playing games (generally any time the phone produces audio although it doesn't seem to be as noticeable when listening to music using the music player but it is still there), while watching the new superman trailer on youtube you can hear the hissing from across the room, you also get pops in the audio when watching youtube videos, these things ruin the phone for me.

I never actually got to test call quality on my first HTC One since I hadn't been sent my new sim card but I have tested it on my current One and I get hissing when ever someone talks / there is noise.

I notice their are a few people saying audio is perfect and they can't hear any hissing a tall but they seem to be in the minority. Unfortunately my current HTC One has multiple dead pixels and along with the audio problems I think I'm about ready to give up which is a shame because this is an amazing phone.

[One (M7) Q&A, Help & Troubleshooting] HiddenSanctum:
I just tested that Superman Trailer with my HTC One and compared it to my Samsung Galaxy Nexus.

I do hear the hissing but only when Beats is turned on. When I turn Beats off it sound exactly the same my Galaxy Nexus.

Also with Beats turned on, play my own audio files there is no hissing.

This leads me to two theories. One, its a software issue. Two, the issue is not the phone but the audio quality of the file itself. From what I've heard Beats seems to amplify everything in the sound itself, thus possibly amplifying the noise that was there already but we couldn't hear it.

Can anyone confirm this with me with the Superman trailer?
[One (M7) Q&A, Help & Troubleshooting] Aziki:
I tested the Superman trailer on a GS3 just to see if it was a problem with the actual file and I couldn't really hear the hissing a tall.

I could understand getting the hissing if you put your ear right to the speaker but I can hear it with the phone across the room in certain situations. I must admit Beats audio does make it worse but as far as I'm aware HTC haven't actually acknowledged the problem so who knows whether it's a software problem they will fix in an update or if it is a hardware problem that can't be fixed without hardware a revision.

-Aziki
[One (M7) Q&A, Help & Troubleshooting] HiddenSanctum:
Do you hear it even if Beats is off on your HTC One though?
[One (M7) Q&A, Help & Troubleshooting] Aziki:
I can still hear it with Beats turned off but it's definitely not as noticeable. Once the trailer gets to a point with more background noise it's even less noticeable still but is still there in the background.

I would probably live with it if I knew for certain they would fix it with a software update in the future but unfortunately even when someone spoke to a manager at HTC they seemed to indicate there was no known software problems. Once I notice something it's really hard for me to ignore it and I know it will bug the hell out of my in the future.

-Aziki
[One (M7) Q&A, Help & Troubleshooting] HiddenSanctum:
I hear you on that one, bit OCD myself. I don't seem to hear it with beats off though. It sounds the same as my galaxy nexus. Fairly certain its a software issue but only time will tell on this one. Phone is definitely one of the best I've owned though. Since you have to swap it for dead pixels maybe try again? Good luck!
[One (M7) Q&A, Help & Troubleshooting] Aziki:
I just watched the trailer on my Galaxy S and if you put your ear right next to the speaker there is a slight hiss in the background but when using the phone normally you can't hear it so I'm guessing it is something to do with the volume / Beats on the One and the front facing speakers. I'm not entirely sure if they would be able to fix it with a software update or not but I'm guessing they could make it less noticeable.

If it was only a minor hissing I could probably get used to it but it can be quite distracting sometimes and unfortunately when watching youtube videos there is cracks / pops in the audio which don't actually seem to be part of the video as it isn't present on other phones, I'm guessing this will be fixed by an update though.

This problem also affects phone calls for me as well, every time the person on the other end talks you get a hiss in the background which is quite annoying. All in all the phone is great and would be a huge upgrade from my Galaxy S but I'm not really sure if I want to wait around for the problems to be fixed when the Galaxy S4 is out soon :/.

[One (M7) Q&A, Help & Troubleshooting] HiddenSanctum:
I see, I was testing through headphones actually. Will need to test the speakers in the morning. Personally I was not impressed and quite disappointed by the S4 when I heard the conference. Seemed more of a S3+. Just my 2 cents.
[One (M7) Q&A, Help & Troubleshooting] Aziki:
It is present when using both the headphones / speakers but it's definitely more noticeable when using the speakers (at least to me).

I agree that the S4 isn't really that impressive, well at least when it comes to design, the HTC One blows it out the water but unfortunately it's not all about design and I know the sound problem will annoy me more and more and I will regret keeping the phone eventually.

It's a software problem and HTC are aware of it, the power transference to the amp may be too high. HTC Taiwan is looking into it.
[One (M7) Q&A, Help & Troubleshooting] Aziki:
Hi,

Was just wondering where you heard this from as in the past HTC haven't acknowledged any problems with the software. (Previously in this thread someone posted they had spoken to a manager at HTC about it).

If this is definitely true and it's going to be fixed in the near future I would definitely consider keeping my HTC One (well, getting it replaced since it has multiple dead pixels ;p).

-Aziki
[One (M7) Q&A, Help & Troubleshooting] Fensy:
I would also like to know where you heard this from as I am just about to send my phone back. If there is a chance that my replacement will also have this issue and if it is indeed a software problem that HTC are working on fixing then I may just hang on to it.
[One (M7) Q&A, Help & Troubleshooting] ste1164:
I was in contact with HTC as my device had that & popping issues.
[One (M7) Q&A, Help & Troubleshooting] Aziki:

I think initially it was beats audio and noise cancelling technology. It is puzzling that some people can hear it and others cannot.

It seems their more recent batch has bit more issues than older...

Thanks, in that case I think i will hold on to it for now and see what the next software update brings.
[One (M7) Q&A, Help & Troubleshooting] indup:
since yesterday my phone has developed a just about audible popping sound whenever i touch the screen. its a very feint pop sound that happens about 2 seconds after touching the screen. i dont have it when playing audio just on scren selections. if i turn system sounds off in settings i dont have it.

is this likely to be a software or hardwear issue? if hardwear then an handset exchange maybe called for.
[One (M7) Q&A, Help & Troubleshooting] slind:
Happening when the speaker is activated. It's a general problem. It's a "plop" when then speaker is shut down. I contacted HTC about it and they say they were not aware of the issue and I had to send in the unit. But as it happened on all of the twelve ONEs I came across, this seems to be a wide spread/general problem.
[One (M7) Q&A, Help & Troubleshooting] yvibes:
I have these popping and hissing issues as well. My phone is rooted and bootloader unlocked so I'm on the latest custom roms that have the 1.29xxx.12 firmware and the changelog from htc included that beats audio has been improved, hissing problems have been improved, sound quality in general is improved. They are still fixing the sound further with the next leaked firmware as well so its probably a software issue and htc are aware of it and are trying to fix it.
[One (M7) Q&A, Help & Troubleshooting] Aziki:
I was just about to come onto this thread and ask if anyone had applied the latest update and if it had fixed the problem.

I'm glad it's at least made a difference and they are still working on the problem to completely fix it. I was planning to send my phone back and possibly get a Galaxy S4 but I think I will just exchange it (I have a few dead pixels as well as the poor audio / hissing problem).

Just out of interest did you have hissing in the background when making calls? (ie when someone speaks on the other end) and has the update fixed / helped reduce this problem as well?

Thanks,

[One (M7) Q&A, Help & Troubleshooting] yvibes:
I don't think I had the hissing when someone speaks but I did have hissing in music playback and popping with external speakers while watching YouTube and can say, for me, it's been improved. Not as bad as it was before and I'm certain in the next few updates it will be gone
[One (M7) Q&A, Help & Troubleshooting] Aziki:
I see, maybe the hissing during calls was a different problem entirely as it seems most people either have hissing from music / videos / games etc or hissing from calls, not both (Guess I was unlucky ;p).

Hopefully they release the new update soon to the UK as I don't want to be stuck with the phone if it still really annoys me even after I've updated it :p.
[One (M7) Q&A, Help & Troubleshooting] lilfurbal:
I have been noticing this issue also. It's sort of like a continuous faint popping / ticking that sometimes fades out, and comes back. However also I have noticed that the issue isn't an issue once you turn the screen off or are on the lock screen. So playing music, then locking it lets you have clean audio through the headphones. Isn't until I turn the screen on and unlock the device that the weird popping sound comes back. So using the headphones for anything with the screen on is a bit annoying... and turning beats audio off just reduces the volume of the popping sound but doesn't get rid of it.

Fortunately I don't really do much with headphones on the phone except for listening to music with the screen off, however if I could discover a fix for it to act good all the time that would just be fantastic. Particularly while web browsing.
[One (M7) Q&A, Help & Troubleshooting] grneyez:
I have a question to ask those who are experiencing audio issues. Are you running a custom rom or using the stock rom when you experience these issues? I was running a custom rom Orio One genuine 2.0.0 and was experiencing the same issues you all had. I did a nandroid backup to the stock rom and played the same You Tube video;s and the audio is crystal clear. No popping, hiss, distortion whatsoever. The audio is crystal clear.

Can others please confirm this by returning back to stock roms, I think there may be issues with the roms and the developers are not aware of? Just an idea.
