Walkie-talkie background sound. Problem with the sound card? - Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl

I have an error that is most likely a hardware issue.
Everytime when sound is involved you can hear some constant background noise with some clicking and clacking sound at the end. (It sounds a lot like when you use a walkie-talkie: for example "blablabla, over and out." *chhhhrrrrr click* )
I tried...
rooting & installing custom roms
changing speaker
My sister's P600 works fine with either headphone, so I guess the problem is my specific device. It dropped a tool on the mainboard once when changing the charging port, could that caused some damage?
My primary question is: Where is the position of the sound card? (so that I can search the area for physical damage)
My secondary question would be: Any other ideas what it could be?

as this is a surely hardware problem, are there any other solutions than:
a. buy a new LCD screen (hard to find)
b. buy a new phone
thanks for the help guys
bump..........
Sorry
Since it is a hardware problem, I can't think of any other solution besides purchasing another LCD/phone. I'm sorry.
That said, I have put my defy underwater many times. The touch screen stop working when wet, but I had no issues with it once it dried. Maybe the problem was from the impact?

[Q] Heavily decreased LED-light.

Hello guys. Here I will post a semi-blurry picture of my HOX, (the black), and my girlfriends HOX, (the white).
As you maybe can see, my led light is very heavily decreased, and I don't know why.
PS: Mine is rooted, my gf's is not.
And it's not because of one single rom, because of all that I've tried, (plenty), none of them have increased my led light.
It might not be important, but it really bugs me that I can't see when I get a new text message, etc.

Same problem for me after updating to JB
Are you sure it didn't get dirty in your pocket around the same time you updated? Just in case get a can of air-duster and give the front grill a good clean, it may save you the trouble of flashing roms and fiddling around. Mine gets dusty and dim all the time.

[Q] Screen colors messed up (Ribbon?)

Hello Desire Z community.
I have met following issues with a Desire Z, and with a little bit of searching it appears that the ribbon might be broken inside the phone (The pictures are enormous):

"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
However, after opening the phone and taking a look at the ribbon, it *seems* to be fine. There is no clear tearing in the ribbon, and it seems like it is OK overall. Can someone of you confirm whether this issue is caused by the ribbon, or by some other variable (screen, bad connectors maybe)?
The screen is distorted, and opening the keyboard "changes" the distortion. Also touching the ribbon while keeping the keyboard half-opened modifies the distortion.
This is my dad's phone, and he rather uses the phone in this condition than his Galaxy S4 :highfive:
Video of the issue:
(Yes, I recorded it without too much effort, don't hate me )

Something like this with at least 3 button?
http://www.radioshack.com/auvio-headphone-cable-with-mic/3300541.html#.VOHpnmPSJ0s&tab=tab3
I have found other solutions but none of them completely safe:
1) This seems great http://www.shopandroid.com/htc-wired-remote-control-stereo-headset/11A29A5242.htm , but it works on cyanogenmod?
2) buy headphones like thes http://www.amazon.com/dp/B007C5S3AU/?tag=stackoverfl08-20 and adapt them into an extension cable ad explained in guide like this: http://www.tested.com/tech/smartphones/2292-how-to-make-any-pair-of-headphones-smart-phone-capable/ or http://www.instructables.com/id/Galaxy-Nexus-and-others-headset-remote-with-medi/ or http://www.wisebread.com/build-a-cable-to-control-your-android-phone-while-you-drive
But I do not have the proper skill to do this task
3) control phone with bluetooth from linux os with sofware like this http://nohands.sourceforge.net/config.html or http://www.mulliner.org/bluetooth/xkbdbthid.php
But I do not know how they work and if they work with playback control as skip track
someone knows help find the simplest solution?

FMTransmiterService running on the phone

Found out that there's a FMTransmitterService (com.mediatek.fmtransmitter) that is running on the phone, but couldn't find any feature on my phone to transmit via FM.
Anyone know anything about this?
With QuickShortcuts, I even managed to launch the FMTransmitterActivity.

It even have a notification, and it correctly mutes the speaker!
However, can't get anything on my FM receiver though.
Hello,
You did not tell- how you managed to get to run the FM Transmitter interface.
There are a lot of undocumented mystery goodies about this phone. The sound is top notch premium too, and they explain it no where in the specifications.
I installed this app called "QuickShortcuts", and then look for FMTransmitter, then select the FMTransmitterActivity, try it!
After I upgraded to 1.33 version of the firmware, the service is gone. :|
Hello,
Yes I see the service is gone. I think they are reserving something for business.
They read these forums I believe.
