[Q] No Earpiece Sounds on Calls, Ideas?

Hi all, as of a couple of days ago I'm getting no sound in my earpiece when I make or receive calls. There is also what seems to be a crossed-out waveform icon on the dialer screen as shown in the screenshot below. I never use headphones, and I've cleaned out the headphone socket. My music player plays through the speaker fine, and when I fished out some headphones the music plays through them fine, and back to the speaker when the headphones are unplugged. I've powered down the phone, removed the battery and rebooted.
Any ideas what else I can try, or does someone recognise the circled icon on the screenshot and know how to remove it?
Many thanks in advance, Warren

Hello, i think the icon is not the problem, if i recall right its a noise reduction or volume boost for calls not a bug or anything like that.. try to clean reflash your ROM and see if the problem is still there.. Make a backup first so in case nothing change you can revert easely

Its a Hardware Problem Buddy And that Sign is For turning the Noise reduction On and Off...

[Q] Possibility to porting/ developing any dialer app for 3g video calling

ok as we know that zenfone series doesnt have 3g calling option (not skype or tango, i mean 3g native video call)
My carrier priced same cost voice calling and video calling
is there any possibility to porting samsung's dialer app or something similar that can make carrier supported video calls? (3g native video calls)
may be there are no one to develop something but in the theory is it possible?
i think zenfone totally disapointment for who before using samsung phones
- bad lcd quality (compare to amoleds)
- non replace battery
- poor plastic back cover, sometimes not fit well with the case
- extremly battery draining,
- charger socket and stock usb cable has bad quality
- in my country it sold with the same price note 3, and a bit lower price like lg g4 note 4 etc.
- good news it has a fm radio, make me happy to using it on the bus going to my work. listening news, live morning shows etc... :laugh:

Can anyone with knowledge of the USB sound functionality help me with this DAC?

So I have a OnePlus 3 and a USB Dragonfly Red DAC.
Common problem with these DAC's is that Android reads the "default" volume as the "max" volume.
So when I plug in the DAC the DAC tells the phone that the default volume is 22 out of 64 volume steps. But the phone hears that as the max volume steps is 22 which makes the DAC really quiet.
Dragonfly Red manufacturers tried to fix this with a firmware patch last week but it didn't work with the OP3.
Does anyone have a nifty way of getting the phone to set the max volume to the correct 64 steps instead of 22? Maybe some config file somewhere?
Long shot but I thought I'd ask.
Thanks in advance if anyone has a fix.

Hi I have the red dac, the firmware was for mqa not androids dodgy volume, basically you need root and an app called alsa mixer from the store first off then you have to type a command in terminal emulator to fix the DFR at a higher volume, i will provide the command ill just find it, I can help further I had this problem and hated it and then I found a fix
https://www.head-fi.org/f/threads/new-dragonfly-black-and-red-discussion.805832/page-185
post number 2769 has the instructions
the app alsamixer is available on apk mirror it is a free app that was on the playstore but has since been removed

The update was actually supposed to fix the volume issues but they kept it pretty quiet at the time. It fixed it for my friend who is on the HTC 10 but unfortunately it didn't work for all models.
Thanks for the info though I'll try that later today. Much appreciated

[Bluetooth Headset] Hands-free not working in Windows 10

Hi all,
I recently bought the new Huawei Freebuds 3i. They are really nice and work pretty good with Android.
In Windows the problems start to happen. As far as I understood every headset with a microphone has a Stereo device and a Hands-Free device. The first is for multimedia such as YouTube, music and so on. The second one is for voice calls, or apps like Discord/TS. While the stereo works fine, the hands-free doesn't. In Microsoft Teams, and all the other apps, I configured audio IN/OUT to use the Hands-Free device, like this:

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
What happens is:
Insert earphones;
Start the call;
For the first 2 minutes the call is perfect. I can both hear and speak;
After these 2 minutes the IN audio doesn't work anymore. The mic will still continue working and the other people will continue hearing me, but I can't hear them.
When I go on the sound panel I see that the sound is playing, but I can't hear it through my earphones!
It's like something goes in conflict in the earphones and they stop speaking. I have tried lots of setting but none of them worked. By now the only way to use the earphones is to use them with an external microphone (like my gaming headset's ones) and it will work. But obviously I would like to use them with the integrated ones.
Has somebody had this issue and solved it?
Thanks in advance folks.
EDIT: I have now just tried disabling all the other audio sources, keeping only the Hands-Free device. It still gives the problem. After some minutes the sound just stops, although the audio seems going on. And obviously, having only this device as output, I cannot hear any sound from the PC, neither YT or Windows sounds.

Sound distortion noticed it on calls when using the loud speaker.

Hello. When talking the loudspeaker (not every time) there is such a strange clicking sound and a little crackling, and passes after a while. Today I observed, but it is related to the update to Android 10. The problem does not occur when listening to music. It is only in the process of talking in speaker mode, so this is probably not the fault of the equipment. When I bought the phone there was no problem. Then a dozen updates jumped in and during conversations on the speaker some crackling, gurgling, snapping. When the speaker mode is turned off, the call quality is OK (no glitches). When listening to music, it is also OK. I read on the web and a lot of people noted a similar problem. I would like advice.

MIUI Global 11.0.3
Stable 11.0.3.0(QGGEUXM)
Android 10 QP1A. 190711.020

same issue, and also i'm on the same build. my workaround is when the speaker is on (while on a call) just turn it off and then on (just double tap it) and the problem disappears, at least in my case.

I use hands free, speaker mode 95% of the time and i have had no problems at all and the audio is clear, though i am in a quiet location most of the time or i would not use the speaker.

have you had this problem from the beginning of having a telephone? I had a problem after the update. That's why I hope that some update will fix it.
