HISS during normal operation. - HD2 Windows Phone 7 Q&A, Help & Troubleshooting an

I have searched the thread for other similar issues but mine seems to be unique?
Occasionally if I put the rear speaker to my ear I can hear a hissing sound, and more often than not when it's doing that I get no audio notifications for incoming texts or email.
Others have reported hissing when listening with headphones that lasts for one or two seconds after a system sound, but with my handset it last for a couple of minutes and prevents other sounds from coming to the surface!
Anyone else having this problem?
Any known cause/solution?

no one getting the same issue then?

Strange static noise

I have noticed that when using the supplied earphones I can hear static background noise when I scroll through menus and buttons while music is playing. This only happens when music is activated and I can hear a low annoying fuzzy static that gets louder the more I scroll for example.
I can barely hear it when I put on headphones but can with earphones, seems quite strange wonder if anyone else experiences the same thing?
No one? Just try it, turn the volume down while listening to music then go to home screen and scroll left constantly or right and the hissing noise will get louder.
Audio chip or whatever must be quite crappy.
Restarted phone and can't seem to hear it now. Strange.
I'm glad that by talking to your self you've managed to fix this problem.
I spoke to myself to soon! Its back and I suspect it has something to do with the wifi sharing. As I activated kies air, uploaded a song, listened to song and hissing is back! argh.

Try force stopping it? I've frozen most Samsung apps but even before then I had no problems at all with something like this tbh...although I don't use the stock music player.
I have annoying static background noise while using earphones, it can be better heard whilr using the phone when no music is playing.
This is a general issue or isolated cause?
I have this!!! I seem to get possibly some kind of audible distortion just before i play a song, and then when i pause the song and touch the screen it makes the weird static noise (and possibly when the song is playing as well, but its less identifiable). For me this noise only lasts for about 5 seconds after i have paused it and then stops. And yes, it also seems to be louder in earphones than headphones.
HAVE YOU FOUND A FIX? Firmware upgrades? Sent it back and got a replacement? what did you guys do? Let me know, thanks.
Could it be evp?

I installed the Backslash Kernel and THEN noticed this, rebooted and it went.
It came back a while after. I also unplugged the headphones with the music app running and the phone rebooted.
Re-flashed the CF-Root KG1 Kernel and it went away, not had any 'noise' or reboots since :/
I got a replacement from orange as this issue was too distracting. My replacement has just come, but exactly the same 'static noise while and after listening to music' issue is still here!!! Is this really what its like for everyone but people don't bother saying?

KERNAL VERSION: [email protected] #2
On my last phone i tried flashing to generic KE7 AND KF3 (using odin). Both seemed to make the sound last for not as long after i pause the music, but did not solve the issue. Will rooting the phone, using different kernals and whatnot fix this? Could it be a dodgy batch of phones from orange? (I have no knowledge of what rooting and kernals actually is, let alone what ones i should use)
I have also experienced this. It seems the screen is the problem since the noise is gone when the screen is off.
What headphones are you using?
I have used the supplied headphones, but i have also tried other headphones as well. All seem to give the same sound but possibly at varying levels of volume. Do you still have the problem?
I use the Sennheiser CX300 II and I do not experience it any longer.
It depends on the impedance of the headphones. If the impedance is 16 ohm I cannot hear it but on 12 ohm headphones it is pretty obvious (but they are able to play louder).
I have not tried the supplied ones myself because they ALWAYS sound awful but if you had a specific name for a proper headphone you have tried, you can easily find their impedance on the internet.
Hmm well i have tried my creative EP-630 headphones which have impedance of 16 Ohm and i can still hear the noise. I have used many terrible headphones on terrible 'mp3 players' over the years and i have never experienced this, so i don't see why i should now go out and buy some new headphones. Although if you are really saying that the Sennheiser CX300 II headphones completely cured your problem then it might be worth it? Was your problem exactly the same as the one i described? Cheers.
It's obviously a problem of the audio amp picking up electrical noise from the other components of the device. I'm skeptic that anything can be done to solve it.
I also can hear some faint background noise on mine when scroling the screen and using memory, but anyway it's very faint... not enough to bother even in quiet environments.
I have to agree, it's bad shielding in the design. Something we will all have to live with.
I notice it most between songs when listening to music. Each songs starts with a little blast of noise.
Hmmm well i've heard that with certain kernals it is not there. Also for me, simply changing to different stock firmware reduced the time that the static sound lasts after i pause a song, so surely that can mean it can be stopped altogether. Im not prepared to give up on this (yet).
I would be grateful for other information and reports from other people about this issue, even simply if you don't have it. :/
...anyone?

but i have found that it does with some earphones... i guess its a matter of shielding, as posted before.

Headphones Distortion / Background Noise

Hi - just wondering if anyone else noticed some background noise / distortion when using headphones on the tab 7.7.
Happens when playing any sound and continues for 2-3 seconds after it stops. Tested with the stock buds and some replacement buds I picked up a few days ago. With my over the ear headphones I can't hear it though. Easiest way to test is just by playing a movie and pausing it.... there is a hissing noise for a few seconds afterwards.
Maybe related: even with headphones plugged in, notification sounds come out of the speakers - this is my first Android device so I'm not sure if that's normal or not.
Just wondering if anyone else is experiencing this or if it might be hardware related. Thanks!

Yeah I get that too. Doesn't really bother me though. I mean, it's not like I can still hear it while playing music or anything...
Mine's pretty noticable, even when playing music/videos. Weird that it's totally quiet with my over-the-ear headphones

Personally, I only really notice it if there's a trailing silence from music or videos, but while there's actually sound, I can't detect it.

Pop noise when receiving a Notification

I just got my moto x Pure a few days ago and i noticed when i receive a text message i get this pop noise after the notification sound stops playing. I went in the settings to change the notification sound and as im switching between them they all have a pop noise always after there done playing or sometimes before playing. If i try to change the ring tone it doesn't happen, they start and end fine with no pop noise. I remember having a similuar issue with my nexus 4 and to remedy the situation i would disable touch sounds and vibration but it doesnt seem to help with this phone.
Someone on reddit said he had the same issue. Anyone else experience this ?
Yep. Happens on my too. It's the speaker going online and standby. Happens on all phones, but in Moto X Pure is loud and noticeable. Cheap speaker? Don't know. Also on my, when playing the tone "Zeta" I get bad speaker crackling noise. Specially when volume is high.

i adjusted the bass in the audio equalizer and it seems to help with ring tones like the zeta, at least i think it did.
I dont get the pop noise when i play a youtube video or listen to google music, so its weird to me.

Thank you for posting this. Now I know I'm not the only one with the problem. I was worrying I'd have to do an RMA, but maybe this'll be fixable with a software update.
Didn't even notice the crackling until I specifically listened for it. Now I can't unhear it. Ughh! This is going to drive me nuts. Similar issue with my N6. Playing music or videos there is no problem. Just notifications and ringtones.

Pretty sure they are. I have both though. I notice the pop very easily at night. I have a few apps set to priority, so they'll ring even when I'm sleeping. Last night I got a couple notifications and definitely heard an audible pop about a second after the tone stopped playing. It seems like it happens when power is being cut to the speaker.
My Nexus 6 had similar QC issues. The phone stopped detecting SIM cards about a month after I bought it. Moto sent me a replacement which I sold because it was NIB. Beginning to worry that Lenovo is cheaping out a bit too much on their flagships.
I don't have my phone in hand yet so...has anyone tried some third party ringtones or notifications? The reason I ask is because I imagine it's possible that the default recorded sounds may have some type of silent space after the "music" or the sound stops causing this. Maybe somebody can try a few home made ones to see if it still happens.
Yes i tried third party notification sounds. Same thing happens
Anyone else affected by this bug
Getting the pop noise as well. It's very noticeable. I'll hold off for awhile and see what Moto does about the issue.
I've got it as described above. Sounds like power coming on and then cutting off. Reminds me of powering on and off an old boombox from the 80's.

I have no POP noise at all. As I said before I think it has to do with the earliest batches that were delivered. Even though I ordered on the second day of pre-order I received mine several days after many others. Maybe I got mine from a second, or later batch?? No speaker distortion either even at full volume!
Decided to return it and get another one. Maybe I just got one of the bad batches. I also had a small scratch on it right out of the box. Would've ignored the scratch if everything else was good... but I can't unhear the speaker crackles and pop.
waiting now for return authorization for this problem, which is a little hairy because I'm not the original owner. I do have the receipt though--shouldn't the warranty transfer?
That pop noise very noticable when using viber...
Also try to press keyboard keys and put the speaker closer to the ear... Its like speakers are turn on/off ...
yeah, it's the amplifier shutting off. happens on crappy laptop soundcards too usually. pretty much all of them have it.

Maybe with custom kernel it could be fixed?
perhaps, but who knows anymore. lol

Headphone pop at high volumes

Does anyone else have an issue with the audio cutting out when the volume is up high when using headphones? For example, during a phone call, if things get loud, the audio will start popping.
Something's telling me that I may have to RMA, but other than that, I have no other issues. Screen is perfect and I don't want to lose that.
I have the same issue

I have the same issue, I purchased my Nexus 6P yesterday and this exact issues is being experienced. I can only have the audio up 3/4 before the earbuds headphpnes start to pop and cut out. I have tested this on myltiple earbuds headphones and the same issue occurs every time. Any one have any ideas before I take it back under warranty.

Buzzing Sound

Hi!
A couple of months after I bought zuk z1, the sound just disappeared for notifications and when music was played through speaker, the speaker would make buzzing noise and it would fluctuate. Also, the sound level would fluctuate without even me touching the volume buttons. Sometimes, when I decreased the volume and increased it, it wouldn't increase and if I decrease it to zero, then even when I would increase it to full I wouldn't hear anything.
Flashing nuclearom fixed everything except the buzzing sound. To get rid of buzzing, I installed Viper4Android but instead of fixing it has brought back all the problems that existed earlier.
Also, the problem is only with phone speaker. The headphones and everything work fine.
Please help me!! I don't think it is a hardware issue because all these problems turn up on their own and they get fixed on their own for a time being.

I said it's not a hardware fault because sometimes when I would clear data and cache of Audio FX and force stop it, everything would come back to normal. However it worked most of the times but not always.

And without audio fx? Did you wipe system, data every time you install other roms?
When I would force stop audio fx the sound would become normal. Yes. I follow the normal procedure before flashing roms which includes wiping everything.
I forgot to mention one more thing. The ringtones would work when there was no notification sound. And after I unlocked the bootloader, the notification sound problem was gone but the buzzing remained. I know it sounds freaky.
And if it's hardware or speaker problem the buzzing shouldn't be there at low volume. But in my phone, it's always there. In my experience, I feel like it's a software bug. When i listen to some song and it buzzes, I can notice that the volume increases and decreases on it's own as if the system is trying to create a balance.
