Muffled Microphone on call + OTA

I have seen several other topics about HTC One owners experiencing extremely low or muffled volume from the microphone for the other person on the line during the call. However, switching to speaker phone solves this issue immediately. Based on my research there is no known fix for this? If some one has a solution I am all ears.
I called HTC to see about getting a replacement or if there is a known fix but they told me that they are expecting an OTA update to fix this issue. Sounds like a load of BS to me but felt I would share my experience to see if any one else has a fix for this.
I am running Android Revolution HD 4.1 Google Edition with Faux 008 Kernel but have tried other roms and have the same problem

Atrix HD audio problem

I have been using Atrix HD MB886 -unlocked- in India for nearly an year now
But Since CM11 M7 build - i have been facing wierd battery drain and problems with Audio(earpiece,speaker and headset)
I then flashed factory image
MB886_att-user-4.1.1-9.8.0Q-97_MB886
and also got updated to
98.4.20.MB886.ATT.en.US (latest OTA)
But the audio problem is still there
Ever since, the speaker sound and all the system sounds, including ringtones, call volume, etc go off by themselves randomly, so I can't hear anything when the phone rings, If by chance I pick up a call while in this state, I can't hear a word the person on the other side utters, but that person does hear me clearly.
Restarting the phone,the sound works perfectly, until for some unknown reason it goes off, and I have to repeat the whole process.
Reading through forums on the web, some people who have had the same problems report improvements and some very few even report having obtained solution to this persisting issue after installing the app "SoundAbout" from google play store. But no use for me.
I have tried nearly all ROMS for Atrix by now - but no relief.
Any fixes., ????!!!!!

im having the exact same problem with my atrix. Tried multiple roms incuding flashing back to stock. I assumed it was a hardware issue but restarting the phone fixes it. Iv also noticed sometimes the sound comes back by itself after a while, even without a reboot. I played songs with the audio muted for a continuous 8hrs and the sound was fine all the while. Anyone else have the same issue or possible reasons what might be causing this..???

HW problem
Hi, this is most likely a hardware issue.
I had same problem sometimes. When I hit the phone, at the top (not furiously), it started working again.
Most likely loose connection with speaker terminals.
you can open it and pull the speaker connectors.

BUG: No volume during calls after 5.0.1?

Hi
Basically there is no sound during calls. You can't hear anything from the other person not even the dialing sound and they can't hear you either. The only fix is to restart your phone but the issue comes back after sometime.
This happened on two Nexus 6s so far that have completely different sets of apps . The only thing in common is that both run stock 5.0.1 with stock google apps.

Can't hear nor can other person hear during call?

So I'm on my 11th day of using the Nexus 6. I have 14 days to exchange the phone through T-Mobile if there's any issues. So far, no real hardware issues with the phone.
Here's my issue though. It's so random I can't figure it out. When I'm trying to call someone, the dialer dials the number, reaches the contact, but I can't hear the ringer and I can't hear anyone talking on the other line. The person on the other side of the line said when they answered the phone, there was no sound or voice from me - it was just dead.
The ONLY way I seemed to fix it before it does it again is to reboot the phone and calls will be normal. My question is, should I exchange the phone? It shouldn't be hardware, right? It sounds to me like a Lollipop issue but I don't see anyone else with this issue. Please help as I want to make up my mind whether or not I should swap for a new Nexus 6.
I'm running stock unrooted and locked bootloader. Thanks.
EDIT: I'm on T-Mobile too.

in for update please

same thing would happen to my wife's nexus 6 too. happens sporadically. don't know what causes it. doesn't happen often. hasn't happened with my nexus 6 yet. i have the blue 64gb and she has the cloud white 64gb.
notice the same thing happening with my father's nexus 4 a couple times too. only way to fix both phones is with a reboot.
thinking that it is a software issue and hopefully will be fixed with the next release of Android 5.1 since that is supposed to mainly be bug fixes.

Are you on T-Mobile? I ask because I think my issue was more an issue on T-Mobile's side. My friend has an iPhone 6 and he had the same issue - it was T-Mobile's cell tower. I'm not 100% sure this was the reason because I still had to swap out my Nexus 6 when I originally posted this because of hardware issues.

Same problem here, answer an incoming call I can't hear them, they can't hear me. Rebooting the phone fixes the problem but only for a few days , then same again.

I'm on AT&T and had this problem yesterday, got a VM from my daughter's school saying there was a 2 hour delay and couldn't hear it (ended up seeing it in my e-mail instead). Then I tried multiple times to make/receive calls same thing. Rebooting the phone fixed it. I wasn't sure if it was a bug since I rooted or not. I've only had my phone for 6 days.

This has been driving up the bloody wall. I hope they fix it soon! Anyone got any ideas?

Guys, if you have to reboot the phone to fix the issue, I would RMA or exchange the phone. It could be hardware since it's happening on different carriers in different areas of the world. I'm on my third Nexus 6 and everything seems to function fine now.

I actually fixed mine by blocking the noise cancellation speakers at the back of the phone below the camera. If the nexus 6p is in a case all you need to do is cover the noise cancellation hole in the case and you will be fine and if not in a case just cover it with a tiny sticker

Having similar issue on Nexus 5!
Problem: When I call or receive calls - I cannot hear anything --- unless I switch to loudspeaker or use a headset.
Furthermore when dialing I cannot hear the connection sounds --- unless I switch to loudspeaker or us a headset.
The others can hear me! So - the microphone works.
I can record and play audio & video - no problem! So the microphone and the speaker do work, somehow not always! Vibration works too.
----------FIXED
P.S: I just got it fixed: It turned out the earpiece speaker contacts were bend and the sticky tape did not hold the part down. After bending the contacts and taping the earpiece down (alternative a small piece of paper to force / hold it down did the job!)
The earpiece contacts only presses upward against the board contacts of the Nexus5 (and 6 likely)!
Currently: Nexus 5 / Nougat 7.1.1 / Nitrogen OS / rooted on TWRP 3.0.3.0 recovery

Caller's suddenly can't hear me

Super weird....
All of a sudden, I'll be sitting having a conversation and the person on the other line will not be able to hear me. I can hear them just fine. I don't hear any beeps, clicks...Nothing that would suggest that I'm doing something wrong. Switching to speaker doesn't help, neither does switching to my bluetooth headset. I am rooted, but other than that completely stock. It's been happening for a while, but now it seems to be happening more frequently on calls that last more than a few minutes.
I am running the latest version of Android with the latest update. I rooted using the NRT and have never had any issues with doing that. Before I wipe completely, just wondering if I shouldn't waste my time before just getting a replacement. I am using Google Fi.

i had that problem. had to reboot and call back. think a clean wipe fixed it. good luck
