HTC One, in call microphone faint/muffled

Post by amckinley on Thu Aug 29, 2013 12:33 pm

Hi,

I am having an issue which has recently started with my HTC One and trying to see if SoundAbout can help.

During calls the person on the other end complains that I am very faint but they can hear me normally with the speakerphone mic.

Using the voice recorder app, the sound seems to be completely fine and I am pretty sure it's using the bottom mic based on my tapping on each mic during a recording.

Could SoundAbout help?

I would have imagined this is a hardware issue, but the fact that the voice recorder app records perfectly makes me question this.

Thanks!

The phone call uses the regular microphone. When you switch to speakerphone, another mic is used on most phones. I'm not sure which mic the voice recorder app uses (by bottom mic, do you mean the one used by phone calls?).

The mics kick in based on the phone's situation. If I try to turn mics on/off, the phone tends to go haywire. The OS wants to control the mic based on whether the speakerphone is on or not.

This means the app can't make the app work better.

That being said, I have read a lot about certain cases muffling the mic and also that some people somehow were able to clean the mic hole and it made a big difference.

Thanks for the quick reply!

I just have an inkling this is a software issue. If I use the voice recorder app as I previously mentioned, the recording and play back is perfect.

I haven't actually listened to what I sound like yet but other people say I am distant and quiet.

It is almost like a gain control is stuck on low or something.

Does anyone know a safe way to clean out the mic?

You know what....it could be a phone call privacy or "enhancing" setting. Look to see if the phone's settings has a setting like this and turn it off, then reboot the phone.

Thanks for taking the time to reply to this.

I couldn't find any settings related to phone call privacy.

However, I used a diag test menu to run a microphone test which worked perfectly with both mics.

I also discovered a few people complaining about exactly the same issue on reddit.com/r/htcone.

Sometimes the phones will have a couple mics. They will use two to figure out what is background noise and cancel it out "Noise cancellation". These are the type of settings that sometimes cause the issue that you are experiencing.

I would try turning off Beats Audio to rule that out as well.

If not using Near Field Communication (NFC), disable that as well.

Thanks again for answering this.

Turning off Beats didn't work unfortunately.

However, there are a couple of threads in the HTC One Q&A on XDA about the same problem and two people claimed to have fixed it by reflashing a new ROM.

I wonder could this mean it really is a SW issue?

It sounds like it. If you are using the same mic for other things and it works fine, then it sounds like a new kernel or ROM may help.
