Noise (Baseband?) problem

Hello,
I have a huge problem with my new LG 2x. I installed CM7 and everything went fine and I was quite happy about my new phone. Then I called someone and he complained about my terrible voice quality. Acutally it's not the voice qualitity, he can hear me clear but there's this static "signal checking" noise in the background - like when a phone is getting a call and lying next to your speakers. (I don't know if there is an English word for?).
I testet all basebands with it's corresponding RILs, the problem occured with all of them. Then I noticed that he can hear me perfectly when I put my speaker on while calling.
Now I went back to Stock with NVFlash on 10b - and updated via the LG update software to 10c (it game together with baseband 0405) - still there was this noise. I tried all basebands again - it seems to be better on 0503 ONLY. Still no great audio quality but at least not this noise.
Do you have any idea what I can do now? Is my device broken? It's really unuseable this way.. and I heard that most people are able to use CM7 with the newer basebands (0503, 0622) - am I the only one who is not?
I'm on O2 Germany on 2G (can't get more than EDGE here) if that matters.
I really hope you can help me
I love this device but I need to make calls with a goddamn phone...
Thanks in advance,
tony
Edit: I didn't test the "0622 Gingerbread only" Baseband because I read somewhere that this shouldn't be used.

noone here at xda? oO

Your phone probably have a defect microphone. You should get it repaired.

i have exactly the same problem (eplus-base)
but the microphone can't be defect, cause i have the problem only at home
everywhere else it's fine..
i think it's the low signal strength..
(cm7 standard ril and baseband 1802)

I live in Finland, operator is Saunalahti. I have exact same, problem. Only baseband is 502, which won't give "electronic noise" to people who i am calling...
I don't have any idea, why it is so. I have tried, basebands 622, 614, 606. Always same "electronic noice".

I also have the same problem and I think that there is allot more people with the same problem. In my case it gets really bad with any Gingerbread based rom.

It's not a hardware fault as it sounds perfect in froyo ROMs

I have the same problem after installing cyanogen mod. Did you find a solution ?

[Q] Captivate - Hissing/Static Issue

I just got myself a Captivate for $120 from cowboom.com. Great phone, just a smaller version of Infuse, which I also happen to have. I really like the fact that charger port is at the top.
Anyways, when making calls, I hear mild but noticeable static which bothers me a bit. When I plug in an earpiece, I only hear it from left ear piece and sound through right ear piece is just fine. Can we tell if this is because previous owner flashed incompatible ROMs/Kernels/Modems, or just a bad hardware? I don't want to return this phone because it has a perfect GPS, but I will have to if the static problem is hardware related.
On a different note, I never knew that GPS on Captivate could be this good. It is a lot better than my Infuse. I had a Captivate about a year ago and GPS on that was a colossal mess. I feel like I need a PhD to understand the inconsistency of GPS chips in Captivates and Infuses.
Thanks in advance.

Here's some more info:
Baseband Version: I897UCKB1
Kernel: 2.6.32.9
Build: FROYO.UCKB1
Modem - I don't know how to find out....
I just rooted it and tried some sound mono conversion apps from the market which didn't help. Thought process was that if I can just mute 'left' and get all my sound through 'right' - that would solve the problem, but none of the apps allow me to change the left-right balance discussed above.

Baseband version IS the modem. Everything running is compatible.
You might want to try flashing a different modem. Top of the development section is a sticky.
Make sure its a I897 modem and not I9000.

If you're rooted then you might want to try flashing a voodoo kernel- that will get you nice sound boost and some clarity.

you can try flashing a different rom/kernel/modem...but if that doesn't fix it then i'm pretty sure that's a hardware problem...

Others can't hear me well during phone call

Greetings!
This is my first post in this forums. They've been very useful to flash, check updates, etc and I've never had the necessity of posting anything since I've cleared mostly any doubt I've ever had about my Android devices. This time, after searching all over the forums and in several other sites over the net I haven't been able to find any solution to my problem. Let me expose it:
Few months ago after having flashed my device to different ROM's, my friends started to tell me that they couldn't hear me well during phonecalls. The sound was not clear enough. They could hear, the volume was ok, but the phonecall the sound call they would recieve was not well.
I thought that this would be related to the hardware, maybe the mic was broken, because once I was thrown into a swimmingpool and I saved my phone by putting it into a jar with rice and letting it rest for few days. However, I have used other programs such as Skype and done the test phonecall so I could hear myself and it went verywell compared to call recorder app tests or regular call, the sound was much better. So I guess that the microphone is still okay and the problem is related to a setting issue that haven't been changed with flashing to different ROMS.
I've been running several ROMS, most of them based in CM7 and I'm now back to the latest stock ROM for America (2.3.5) and the problem is the same.
Any advice will be very apprecciated!

Thanks for the answer.
Actually, nothing of the posted above has worked out. If its a software problems how changing hardware would work?

if its still there is a problem after flashing stock one...than its probably your mic need replacement..!

I just cant figure how the mic works well with skype and not with phonecall and how changing de mic would fix it

[Q] Severe phone calls problem

Hey there,
I know it has been discussed partly, but with I think different aspects and details than I have. To cut it short: in about 50% of my phone calls, be it with good or bad reception, people cannot hear me speak on the phone.
The fun thing is, this cannot be connected to the internal microphone since I have it both on the normal mic as well as my bluetooth headset. No matter whether I call them or they call me. Sometimes (!) it helps to mute and re-enable the microphone on-screen, but this is not always effective. I thought this may be related to a bad combination of firmware and radio, but I recently switched to InsertCoin GE und updated both FW and radio, to no avail as regards to that matter. Furthermore, sometimes phonecalls just drop in the middle of a conversation, with no change in signal quality as far as I recognize.
Does this sound like some software thingy (and one might have a solution) or would you believe this is hardware related?
All the best in advance

Nobody having an idea?

Hi can you tell us what exact combination of Firmware ROM Kernel etc you are using currently?

Hey there,
of course, I picked InsertCoin GoogleEdition with the corresponding 3.06.1700.10 firmware that's offered as a complementary download for the ROM. No hands on the kernel, left the one coming with the ROM. Does that help ?

can you do a nandroid backup and try with another ROM? You could also ask in the thread of the ROM if someone got a similar problem.
I would also downgrade the firmware to the latest for HTC One (non GE). this should not be the problem but just to be sure

Yeah, I think I can. But I came from a 4.2.2 ROM with the latest radio, TrickDroid 8.0 and I had the very same problems. Does it more sound like a hardware than a software issue?

if it happens with other ROMs too it is most propably a hardware issue

Issue with my I9000's microphone during calls

During some phone calls, I have to "scream" in the mic so the other person can understand me, but on some calls, the mic is working fine and even if I whisper, the person can hear me. I have kitkat on my phone, have tried CM, CyanAOSP, Mackay, SlimKat. On all of them this problem appears sometimes. I have experienced this on 2g and 3g having the signal bar showing full signal. Also my Baseband/Radio/Modem is JVT (came when I flashed CM). Could it be the Modem or the Mic is the problem and it works fine or bad when it wants and I have to change it?

Quickest way to trace the problem is by deduction, If you did not have this problem in jelly Bean or gingerbread, than its more to do with Kit kat, meaning your mic would not be the issue, so try change modem . try ICS modem from [Toolkit][A.I.O Rescue & Recovery] My Android Collection. or the previous modem you had in gingerbread
But if you had this issue all the time , immaterial of ROM, than its time you take a look inside your phone
Check this out! Links to useful Guides and " Banned " Documentaries ​

The problem appeared some time ago, can't pinpoint the date or what changed, but I will try a different modem and if that fails, will go back to test JellyBean or change the mic
