[Q] No sound during a phone call

I'm having an issue with my Xperia Play. During a phone call, I usually don't get sound unless I switch to speaker mode or I plug in earphones.
Sometimes it works, sometimes it only works after I switch back and forth the speakermode.
I wonder if it's a hardware or software issue. Anyone could help ?
edit: I think I had this issue after rooting and unlocking the bootloader but I can't be sure because I didn't spend a lot of time with the phone locked down.
edit2: I rooted by flashing Bin4ry's package. I read a bit about that and it seems it can have a negative effect on the baseband version not being the right one for my 2.3.3 firmware ?
Here are my version numbers:
Build: 4.0.A.2.368
Kernel: Doomlord #3
Baseband: 8x55A-AAABQMAZM-20302204-36

Bumping just in case. Someoe knowledgeable could see it.

I upgraded with flashtool to 2.3.4 and the issue is still there.

No sound during a phone call
Hello I have this issue too, I hope someone will recognize my post
While I dial a phone and press call (then earphone turns on) I hear a GSM signal sound (same as if you hear your phone signal in a PC speakers) instead of voice.
In service menu if I press Earphone test i hear this high frequency sounds too.
I HAVE already REPLACED BOTH CABLES WHICH CONNECT EARPHONE AND MOTHERBOARD (1.flex and 2. the one with front camera and earphone included).
So cable replacement DID NOT SOLVE it.
I thought it is SW stuff, but I FLASHED .62 ROM but it is STILL SAME.
New .80 BASEBAND DIDN'T HELPED to me.
Last time my GSM signal was crashing sometimes, If I tried to connect manually it told me that my sim card is not allowed to connect to my operator... something like that
my phone R800i and I don't remember when it started, I think in the morning after party last month
Any ideas what to do guyz? :crying: :crying:
Really want to solve this :cyclops:

Probably if you return to the Stock Version. Also make you have not by accidentally damaged the earpiece with water, even if you were sweating from you ear or something because it might not always be the cables that are wrong but some other HW problem.

Hello, I wrote it all in a previous post, my earpiece is new and .62 is stock ROM, In my opinion there is some HW problem in gsm signal modulation. I was in a smartphone-repair shop and they told me it will cost too much. I think this is the weakest point of XPLAY, because my friend has XPLAY too and while he dial a number and start calling, phone screen turns black and no hardware keys can wake up the screen..
Then I discovered only power button works here after checking ''Power button ends call'' in Accessibility settings. But it is still annoying.
But my problem is not solved, I have to phone with headphones connected or with rear speakers as audio output :/

hi please help
i have this problem No sound during a phone call please help

News?
Any news about this issue? There is load of threads about an ear speaker, I can still hear only GSM signal beep in it

Call Sound Quality

Hello,
the sound quality is very bad. The strange thing is, the problem occurs only using the phone app. I am using the stock phone app.
Any idea? I need help. All other things are working but I can't use the phone to make calls. It sounds like distortion ... . Already the sound during ringing has the problem.
The problem only occurs with the internal front speaker. No problem if I use the rear loudspeaker or headphones.
Is there a wait to solve the problem?

Call Sample
Hello,
here is an call sample. I know the quality is not perfekt beacause of the notebook fan. I call another phone and after ringing the mailbox of the called person starts. Especially at the end were the mailbox voice occurs the problem is very clear. It is nearly impossible to understand what is said.
Is this the normal sound of the internal speaker (front)?

of course not.

Hello,
thanks for the answer. Found the following thread.

Strange thing I am also using this phone in Europe. I am quite sure the problem is not a hardware problem. Because if I use the phone with VoIP service app, the speaker just works ok.

I would try a clean flash of a custom rom, factory reset maybe (was it always bad?..)? I also had problems with the internal speaker, if I have set the volume higher than half, it made crackle sounds. But it was a hardware issue, (in skype, fring,viber also had this problem). I had to send it back to the usa, cause I live in europe and literally no one could fix it here because of the lack of hardware. I had to live without my phone for a month.. annoying thing, but now it's ok

First of the time after buying I didn't use the phone for calling. With Skype I will try again. Also the VOIP test. How did you manage the repair? With ATT or Samsung?
Its not only because of the time. Also because of the money for transport and repair.
Thanks for answering and help!

Microphone Problem on HTC One V CDMA

I havent been able to figure this problem out, I think my phones mic is bad.
VERY low volume. When I call people, they can barely hear me, but I can hear them perfectly. I have confirmed this by calling my other phone, I can barely hear my voice coming from the one V
I have tried rooting, rom'ing, and different kernels. What actually controls the mic? Should I try a radio update?
If there isn't an obvious answer, I think I'll try sending it in. Its only 7 months old, and HTC just fixed another One V i have that was bricked. I have also tested the same software on my other one V and the mic works perfectly...
really weird, because its just very quiet even though it technically works...
edit- the one v thats not working has a radio of 1.00.00.0521_2
and the one v i have that works fine is radio 1.00.00.0928
otherwise, everything else about the two phones is the same. hboot 1.53.0000
edit- before everyone posts like crazy trying to help me (har har), i am rru'ing back to stock, then doing an ota update to try to push to the new radio. i will see if that fixes the mic, and if not, im sending it back to htc!

ugh! partial success! :/
So after the rru, the phone took 3 different OTA updates. Then I tried calls again. I use groove ip, and on default settings my other One V works great. Again, the mic on this phone ive been working on is too quiet! BUT I do notice a slight increase in the volume.
So I went into settings for groove ip and maxed out the mic gain- and it worked pretty well! Its not quite as loud as my other one v with default settings, but it does work seemingly good enough.
So weird! I already tried cleaning the mic with contact cleaner, and even taking the rubber block out. What sucks is now, do I send this to htc anyway? I have a feeling they will tell me it works so they won't know what to do...
Ill update if anything changes...

Fixed.
Sent the phone into HTC. Not sure what they did, it didn't seem like much. But the mic works properly.
I go to install a custom rom, and mic is f'd up again! Restored the backup I made, and the mic works properly again. My other OneV doesnt have this happen with the same custom rom installed :/ The mic actually works, but what I think it is- it's stuck in speaker phone mode. It doesnt matter if your right on the mic or across the room, it sounds the same. Not very loud with lots of background noise.
So, basically, I have to leave this phone with the stock rom I suppose. If I can overclock it I'll be happy. Just so weird why my other phone doesn't have this issue after flashing to custom roms...

Callee: very bad audio when calling

Recently I have been getting very bad sound when calling someone.
I can hear the callee perfectly but they can barely hear me, I sound like a 'fish in the water' or with a very big 'echo'.
This has been the case after updating to Lollipop.

I Am Assuming you are using Stock Lollipop FW from Sony
Head to Settings>Call
Enable Microphone Noise Suppression, Set the Equalizer to Bright and enable the Speaker Voice Enhancement
Also make sure you are on Max Volume when In-calls

Nope, I only tried the solution suggested above, I have yet to encounter the problem again.

I just tried same thing with equalizer. I will see if this will work. @Devenda, any news since 2 days ago?

Nope, still stable, I tested it but the audio was clear.
Problem is that this issue comes and go's randomly, so all I can do at this moment is wait...

None of the suggestions described worked for me. This bugged me so much I was forced to run to RR rom.. Problem solved but I miss Sony's great battery life ??

I have the same problem.
Only the equaliser was different (normal), I've changed it to bright and will see.
Don't you think it is a problem with radio reception ? I'm not sure but I think I have not the same number of bars than before. I haven't got an other 4G phone to compare.

Equaliser doesn't work for me.
I have changed prefered network, it was 4g prefered. I've changed to 3g. It seems to be working.
Can somebody try ?

I solved my problem during the calls when i unchecked the improvement of voice

If you have tried all the other options and still not working but you have v4a sound mod installed, this might help - http://forum.xda-developers.com/sony-xperia-z1-compact/help/viper4android-deactivates-mic-t3124764

I had same problem after update to lollipop and try everything mentioned before and nothing helped. Then I low down speaker volume ( volume key down) while call is active and that worked for me. I suppose that lollipop have some problem with duplexer. Level of sound in speaker is litle low but at least caller can understand me normally.

Greetings, I hope you are fine.
I'll just let you know my experience with that, I had a similar one to yours. Instead my voice was stuttering and ghostly, like something came out of Paranormal activities. xD
The only solution I found to this was that it was a problem with the hardware itself, IE. the mic of your phone. Maybe you wanna give your phone to the warranty company and see what they say about it. In my case, they fixed it and it's working fine now.
I hope I helped
Yours.

Main Microphone not working on phone calls! HELP

When i call, people hear me really distant and distorted, if i tap with my finger they can hear the sound. When i use a voice recorder app and set secondary microphone it records fine the audio, and with main microphone if i scream near the lowergrill it records low volume voice. Already tried reinstalling OS, from CM12 to lollipop stock firmware, Problem persists.
What else can i do? i used to have CM12 with no microphone issues for many months and suddenly it happened.
Please help me, a phone where i can't talk is not a phone. I CANT FIND any fix in the web for this, and in my country we have useless techs. so it's up to me and the web...

He's already said he's put stock firmware back on.
Try to go into the service menu and do the microphone test.
(To get into the service get your phone dialpad up and type in *#*#7378423#*#* and select the appropriate text)
p.s. *#*#7378423#*#* corresponds to *#*#SERVICE#*#*

I was just wondering this yesterday, thanks for the extra data.
And yes, already tried that. Secondary microphone records fine but the main doesn't.
Weird that if i use Whatsapp Voice send it does Ok. phone calls are the real issue and the most important though..
there should be a work around for making secondary work for phone calls;
anyways... SIM card is possible to be damaged so that only phone calls are bad? GSM, LTE, g3/g4.. I'm up for any clues about this.

And no more replies... Guess it's over. :\

hi. did you solve the problem. i have the same problem, and i dont know how to solve it

I sent my phone to a technician and they changed the microphone; or so they said. it works now. But another drop made my camera to fail and they said even changing it won't work.
Is this true? :\
