Intermittent problem with sound during phonecalls. Please help! :(

The symptoms: SOMETIMES during incoming phonecalls Raphael rings (plays sound) but when I pick up the call, suddenly the phone sort of "mutes itself". I can't hear the person talking, nor can they hear me, even if I hang up and try later. The only thing that helps is a soft reset.
It's difficult to count the occurence, but I'd say like once a day at least.
I have already tried Hard reset, the phone is acting funny with only Advanced Config 3.1 and PHM RegEdit installed and a few tweaks applied (just Boost TFL3D performance tweaks and SMS conversation disabled)
I'm running stock 1.90.401.1 WWE FW, I have flashed a new radio version (1.02.25.31 Cingular) though.
Any advice/suggestion is appreciated.

Unless the new radio is giving you 3G, I'd go back to the stock ROM/radio combination and see if that works. I'm currently using the Cingular ROM/radio as well and I've never run into these problems, but that may be due to different hardware.

Thank you very much for a quick reply.
I'll try flashing the stock radio and will report back...

So, I flashed the original radio and it seemed for a while that the problem was gone.
Sadly, I must report that the problem is persistant as I had to restart my phone right now. When the "sound mute" thing happens I don't hear anything while answering phone calls (even though the phone rings normally!) and also when I try calling any number from my contacts including the operator hotline.
I really don't want to return the phone because I like it very much but having a phone which has problems with phone calls is kind of silly.
I'm at my wit's end.
Will anyone help me please?

I have a small update - today I was so desperate, that I tried flashing a custom ROM (namely DCS-TouchPro-v1.0 Hybrid) and the phone went bonkers right at the first incoming call. However, something IS different - now the phone is not silent but starts "buzzing" - making a long uninterruptible sound that lasts until reset.
Do you think I could have a HW problem?

I HAVE EXACTLY THE SAME PROBLEM!!!
I already posted a message in the "Issues" post of the Raphael Forum, but apparently no one had the same issue so far.
I did many hard resets (and installing gradually less things), it still bugs.
Currently the only tweak installed is the scorpion one to have 4 rows of icons in a menu.
My Raphael is behaving like this since 1 week. The bug occurs once or twice a day as well.
Anybody with some good IT experience has got an idea of what could be wrong with it?
Do you think it is more software related or hardware related?
Today it also crashed badly (grey doted screen and noway to make it work again by turning off. Had to soft reset).
PLEASE DO HELP US, because I'm using the phone for professional reasons and I'll really have to send it back if it keeps on bugging this badely!!!

I just sent a message to HTC Support.
Let's see what they say.
I'll post their response so those who have the same problem will know what to do.

Oh boy, I must say I'm glad not to be the only one with this problem, even though I never wish bad things to anyone.
While googling the problem, I found a few Diamond users with exactly the same symptoms, however most of them solved this by exchanging the device for a new one, so this won't help us much...

Me too, I was wondering if it was because I did something wrong with the phone...
But if I'm not the only it means that there is a problem with the phone itself.
Anyway I'll wait for the official answer from HTC...
I'll post their answer as soon as I receive it.

I'm actually quite curious what their answer will be.
But I wouldn't hold my breath for any miracle, so I'm preparing to send my phone to the service center to have them look at it...

Well.. that makes 3 of us then
at first i thought my symptoms are different, but Flippy confirmed they're identical.

I have to correct myself - I wrote that when the thing happens, the phone still rings, which is not true. It rings just the first time before the problem occurs, but then it's dead silent.
So it seems our symptoms really are exactly the same.

Told ya AntiProxy!
So we are indeed only 3. It is still ok, it means that there is only a very small proportion of of Touch Pro that have this problem.
Now let's only wait HTC's answer...

spoke to HTC support today.
not that i expected them to figure it out or have a solution at hand, but i figured what the heck.. give it a shot.
their solution?
hard reset.. the guy would swear by his daughter that a hard reset will solve it.
i just thanked him and hung up.. *sigh*
don't you just hate it when techsupport's solution to everything is a reboot or reformat.. when you know that's not the solution anyway!

Well, I tried already doing the "Clear Storage" through the settings -> system panel, but it still has got the same problem.
I'll give them a call aswell to see if by any chance I can get on the phone 1 person who will be able to provide us a better technical advice

Hard reset won't help, I've already done it like dozen times and it makes no difference...
I tried flashing the phone to the stock 1.90.405.1 ROM and so far (a day and half) I have NOT encountered the problem. It is too early to start hoping, but I wanted to let you know - if you don't mind flashing your phone, give it a try.

Zillator, can you keep us posted for like 1 week?
If in 1 week the phone doesn't present again that problem I'll flash it as well (I didn't want to flash it because I wasn't sure if it could void the warranty). If during 1 week you don't have the problem again it'll mean that out initial ROM was defective...
Thank you Zillator and please let us know. (by the way when I'll call them tomorrow I'll ask them if flashing the ROM to a newer stock version voids the warranty).

AntiProxy, it might be a bug in the ROM we have in our machines. That's why maybe flash it could be the solution. Nevertheless I'll ask about the warranty tomorrow when I call them and let's see how it goes to Zillator.
If his phone doesn't bug for 1 week, there might be a big probability that the problem came indeed from our ROMs.

Guys, don't worry, I WILL keep you updated. I know how much the problem bothers me, so if there's anything I can do to help you, I will definitely do it.
In the end, that's why we are here - to help each other...
AntiProxy: is your stock ROM 1.90.405.1 WWE? Because mine was different (1.90.401.1 WWE) and I had the problem. Maybe Flippy_TK is right and the problem only exists in the 401 ROM.
I'll continue testing and we'll see...

terrible echo during calls

Hi,
I got the XDA Diamond Pro (Touch Pro O2 germany) yesterday.
During a call,the phone generates a terrible, slightly timeshifted echo of the own voice. The voice of the other person is normal and the other person doesnt hear an echo. I have tried it several times with different persons and networks (mobile + landline)...always the same phenomenon...sometimes more or less.
Is this normal with the Touch Pro? Do you also have this echo while making a call?
regards
10mabo
(sorry, my english is probably not the best)

Nobody with the same problem? Are your Touch Pros without echos?

No prob for me. Never heard something similar. What about your signal strength? Do you have good reception?

No problem here aswell.
tried a hard-reset already? I noticed that my TP worked better after I did a hard-reset (more stable and quicker), dunno why though.

Thank you for the replys!
So it seems that my device is not working properly :-(
It´s already on the way back to the provider.
regards

Holy crap! I just got another exchanged fuze and it's having the same issue. I'll try flashing to a new rom and see if that works.

When I first got the phone I noticed that my voice would echo but it stopped happening on its own. I think it was occurring because of bad reception. At that time my phone was having major problems with the data connection also and I figured it had something to do with ATT's towers.

I have experienced this echo, too, but considered it to come from reception problems as it does not happen on a regular basis. I.e. some calls are experiencing this echo, some do not.
CU,
Cactus World

I assume you mean flashing another radio rom, right? I have this issue on my Fuze as well. I flashed to NATF's rom, but am still running the stock radio rom that came with my phone: 1.02.25.32.
Did a different radio rom help you??

I changed my radio to 1.08.25.20, but I still have the echo. Do you think this is a hardware or software issue? Thanks!

I had the same problem I think with mine. It went away after a while when I was using NATF v2.2 but then when I flashed to v2.3 it came back. This was because the incall volume went down. So increase the volume when you're in a call and that should fix it.

I'm not sure if this is the same problem, but the same thing has happened to me with both the Fuze and the Tilt. What I think the issue was though was that there was a slight lag between the time I said something and the time the sound came out of the earpiece on the other phone. The other phone's mic would pickup the sound of my voice and send it back to me. Very annoying. The problem was always solved when the person I was talking to switched to headset.

Same issue
I am experiencing the same issue, but it does seem to come and go depending on the in-call volume settings.
Obviously, no problems on speakerphone, which I use frequently.

Stock Radio, Stock Rom, no bloat

I just switched away from NATF v2.3 to aruppenthal's ver2 final ROM and the echo has cleared up! Thought I'd share in case others want to try...

need help. Cannot hear on other end when making a call!

i just recently flashed NATF's v4 rom on my htc with no problems.
Now, whenever i make a call i cannot hear on the other end normally unless i put it on speaker!!

I'm guessing you flashed v4.4? I had a similar problem on 4.4, but it went away on 4.5 for me. To make the volume louder during calls (and overall too), I installed the Audio_Lighter_Boost.cab from aruppenthal's rom thread here: http://forum.xda-developers.com/showthread.php?t=467592#6
Just install the cab and soft reset. If it is still not loud enough for you, follow the directions for the AudioPara3.

no, i have 4.5 and sometimes when i make a call, i cant hear the person on the other end.
and i tried the method that you suggested and it didnt work =/

Sapphire Radio Noises

Anyone else having an issue when on the Sapphire Radio where the person receiving a phone call hear's loud scratching/echoing/"tin" sounds?

Hmm no... Although with 5.0.1H I could hear my own voice echoing back all the time... Moved to 5.0.1G as you can see in my sig.

I have the same issue.

Since I flashed to 5.0.1H (now on 5.0.2H) I got a lot of complaints like that. Whoever is on the other end also gets really aggravated at noises such as closing a door or something, which never annoyed anyone before. It's really weird, I keep thinking of leaving myself a voicemail to hear it but I haven't done it yet.

I seem to have the issue on all builds (RC33, 5.0.1G and 5.0.2H) but only with the sapphire radio driver. If I use the RC33 radio, no noises, but the battery life sucks... hmm....

yes, hepened to me with any 5.01g, 5.02h with old radio, upgraded to latest saphire radio and all ok now.

[Q] NS i9020 weird call issue

Hello,
I've been a user of the xda ROMs for quite some time and i appreaciate all the work that's been put into the community.
Sadly, i have stumbled onto an issue i cannot solve myself, so i am seeking your help.
Description: When receiving a call and answering it (phone vibrates and rings), i cannot hear the other person, but they can hear me. (Speaker on/off doesn't do a thing, volume rocker up/down either). If the person calls back within a few minutes, i can almost always hear them and have a normal conversation. This does not happen in 100% of the cases, but in more than 50%. I have switched ROMs, kernels and radios (ATM i have CM7.1 RC, mar1x bfs v4,5, and XXKB3)
Is there any hope?

same issue on i9020t
I been having the same issue, but not quite as frequent, on my I9020T. I've experienced it with Cyanogenmod 7.1RC1 and NSCOLLAB (also based on CM71). I think I had it with CM7.0.2 and CM7.0.3, but can't remember for sure. The problem does not occur when I revert back to stock 2.3.4 rooted.
A somewhat related post in this forum, http://forum.xda-developers.com/showthread.php?t=1188264, got me thinking. The OP had a similar problem on an I9023 when bluetooth was enabled. I've noticed on NSCOLLAB that DSPManager is running a "Headset" service. I do not have DSPManager installed on my stock install.
Can someone more knowledgeable tell if its possible this service could be related to the problem with callers not being able to hear me. FYI, my bluetooth is normally off and I don't use a headset. I'm back to running NSCOLLAB 1.3.8, but I've disabled the Headset service. If the problem doesn't occur for a couple days, I think I may have something.
dinuvali, is the Headset service running on your build?

Removed DSPManager earlier. Just answered a call where they hear me but I can't hear them. They called me back, all normal.
Oh well, rolling back to stock for now.
Sent from my Nexus S using XDA App

Thank you for the reply,
Yes my CM 7.1 is running the DSPManager service.
Also, my neighbour who has the exact device as me, but stock unrooted, has never experienced this problem.
Along with this problem of not hearing the other person on the first call, i also get the dropped call once in a while (not only after 3 mins of talking, but also while the phone is ringing and they still haven't picked up yet)
From all the posts i've read concerning this issue, i think it's mainly a hardware issue, but maybe it can be bypassed with some sort of tweak.

Major breakthrough imo
Pressing Hold (left upper corner) and then unholding will render me able to hear the other person!

Great find! Come to think of it, I never had it happen when I answered someone and immediately hit speakerphone, something I do alot when in my car mount.
I think I'll reload NSCollab, new version just came out today. When it happens again (unless they fixed it) I'll try this out. Thanks!
