a pulsing noise - Nexus 7 (2013) Q&A

Hi guys does anyone know what is going on here. Sometimes when I am trying to activate Skype or some sound with my Bluetooth or headset I get this pulsing noise, every 0.7 seconds or so, and it's not loud at all it's just there no matter what volume I set and only way to get rid of it I have to restart whole system. Now I am thinking about it same noise sometimes on my Galaxy S 4. Can it be because of my particular headset ? Anyone have anything on this issue ?

There is no sound from speaker

Hi guys. Untill today i was using my BA without no problem. I use WM 6.5-R5 when someone call me the phone ringing and i can hear the sound coming from the speaker, but when i answer it there is no sound from the speaker. when i try to play an mp3 there is no sound too. when i call someone there is no sound i can not hear the dial tone or the persons voice. the speaker works only when receiving a call and there is only ringing sound. it happens suddenly. it was working very normal untill today. i just flash the rom and there is no change still no sound. what is the problem? does anybody know?
1. check the system volume in the task bar, maybe the right bar is up and the left one is down, that would cause that the only sound you can hear is your ringtone, and nothing else
2. if that is the case try putting the left one up, if that works and there is still no sound, check again, maybe it lowered itself, in that case, re-flash your device (occured to me once)
3. if both points aren't applicable, look up the settings for sounds & notifications (very unlikely)
i personally believe it is no. 2, as i had that issue myself just a few weeks ago.
i checked everything about sound but nothing changed, then suddenly it come back to normal :S now there is no problem thanks anyway

LG KS20 strange sound during call (boosted microphone?)

Hi, I didn't found any similar problems, so I start new thread.
I have LG KS20 and changed some ROMs on it, but the problem remains the same.
When I call somebody or somebody calls me, he hears strange sounds similar to if I'd be near some big speakers, not echo, but you know, when you put the phone near audio speaker, you hear these sounds. After about 10 seconds it becomes silent and almost gone. I think it has something to do with inner microphone and speaker, I should say the microphone is overboosted, so when I get in call, it after 10 seconds automatically controls itself quiet, but when a new call, it starts over again. However I didn't find in registry anything related with mic gain control, I should try to minimize it's boost at first.
Do you have any thoughts how to fix that strange sound?
I have the same problem,
Does someone know a solution
And I have that problem, did anyone tried with handsfree is it same or is it better?
I should try that soon, also I will maybe try to clean mic somehow...
Anyone help?

A couple of problems with my g-nex

Okay, i love this phone, but a few things are happening that kind of freak me out i was wondering if anyone else is experiencing these things.
1.) If you have UI sounds enabled.. ie...click noises for anything you select on your phone screen. Something wierd happens, i was wondering if anyone can test this and tell me if their getting the same thing.
Please be somewhere dead silent. Click anything and listen for the UI sound... now wait a couple seconds, probably 3 seconds and then you will hear a feint "pop" after not doing anything in that time. The "pop" sound almost sounds like that noise when you have your stereo hooked up to something and you unplug it while its on..that hot "pop"??? i dont know how to describe, was just wondering if anyone could test and see if their gnex does that too.
2.) I dont know if this is related to #1, but if im listening to my gnex through headphones, the UI click noises will all be followed by a feint hiss. Also when i unplug the 3.5 mm jack, i can hear a different type of hiss through the speakerphone like 2 seconds later.
3.) This has happend to me 2 times now. I will not use my phone for an extended period of time..probably 2 hours ish... When i turn my phone back on my touch screen isnt working, i cant swipe to unlock or anything. But i can still hold the power button and get the power-off menu, or press the volume rocker keys and lower the volume / raise the volume. I have to pull battery to get it working again.
4.) My gps voice sounds terrible, it sounds distorted at no matter what volume i have my phone at
5.) Kind of minor, but lets say im in my car and running audio through my g-nex, when i unplug my 3.5 mm cable from the gnex, the gnex will make a hissing noise about 2 seconds after unplugging through the phones speakerphone.
i really dont want to have to return this phone, but i mean all these annoyances are really hard to live with. I hope someone can give me some insight maybe even tell me their gnex has a problem, so that im not the only one having these problems.
Dont know

I have long suffered the same issue that the OP is talking about. It is a seemingly random pop/crackle noise that happens AFTER touching the screen or after a vibration. It is very strange, almost like static buildup that is then played through the speaker. It doesn't matter if haptic feedback is on or off, or if the phone volumes are turned off. It also doesn't happen every time, or can happen multiple times in a row.
Someone mentioned at one time that it might be NFC related, but when having the problem I can toggle the NFC on and off and it doesn't fix it.
However, it has magically disappeared over time on certain roms, and I have managed to keep the same "data" backup that I reflash after a fresh rom install. A fresh install of nearly any CM-based rom has the problem. It leads me to believe that some setting stored in the data partition causes/fixes the problem. I would really like to figure out what it is so that I can actually do a fresh install without carrying over junk files from ancient rom installs. Does anybody have any ideas?

The crackling and pop sound is when you hear the DAC being muted after its not in use, This is totally normal, to reduce this effect try disabling any equalizers you may have or anything else that would modify sound in any way.

What's wrong with the call volume???

So everything about the watch is beautiful except for one annoying fact. Whenever I place a call or receive a call, the sound of the other person is so low, that I can hardly hear them. I have the volume on my phone on high for phone calls and music plays loud on my watch, so what is the deal?
Has anyone else experienced this?? Should I go immediately to the store and get a replacement ASAP? or is this a bug that is common with the update or fixable?
Help a girl out, please!:fingers-crossed:
Have you tried adjusting the volume during a phone call on your phone? I think you have to have an active call to be able to adjust the bluetooth volume.
