No audio during phone calls

[fab_m]

Hello Community,

I can’t hear anything on a phone call.
My correspondent hears me but on my side, I do not hear him.
if I put on the speaker the audio comes through
if I plug in a headphone (just TRS) the audio comes through the earbud.

I can’t find any solution on this forum neither on the teracube discourse
(I can see that several thread asking help about the same problem).
I have a teracube 2e SN 2021 with /e/os 2.5 s emerald.

I already try all these steps:

Goto Settings > Apps & notifications > Search for “Phone” > Clear Storage
Soft reset
Backup and factory reset

But the problem persist.
I’d like to able to make phone call with my phone, any help is very much appreciate.

Thank you very much

Hi @fab_m welcome to the /e/ forum.

You might use the app Checkup, community.fairphone.checkup, it should work on most devices. This will allow you to check both Ear and Rear speakers in case it is a hardware problem.

Just one, likely stupid thought: sometimes phone auto-connects to bluetooth headphones nearby and then I wonder, why I am mot getting audio output. Disabling bluetooth while testing would rule out this factor…

Unfortunately, that’s not the issue. I and other people here in the forums have had the same problem, as well as a couple of XDAforums and Reddit users (which I won’t link here, but they can be easily found by searching).

No audio from earspeaker during calls (since approx. e-1.8)

Way back when I installed an OTA upgrade (to 1.8-q, I think), on the Sony XZ1 Compact, sound stopped being conducted through the earspeaker during calls. Since that upgrade, to hear anything during a call, I now have to either enable the loudspeaker or use headphones. All other audio functions (music, etc.) do transmit sound through the earspeaker. The person called from or calling to my phone cannot hear me. [EDIT: Oops… my bad. They hear me, but I don’t hear them.] I had this problem once bef…

Sony xz2 compact: No sound in call since 1.8.1

Dear e/os’ers Device: Sony XZ2 compact Very fond of this project, and have been using it for a year without any problems. However since the latest 1.8 update (1.8.1) I lost the ability to have sound in calls (phone/whatassp/signal) sound/audio in calls works if I use speaker microphone works (record sound item and play works) What did I try? full reset of app preferences in 1.8.1 full format and clean install of 1.9 Any ideas? This really seems like a software issue. Regain your privac…

No Audio from Ear Speaker (#6827) · Issues · e / Backlog · GitLab

For me, two different fixes seemed to work, but only for a short while:

1. Making an XMPP and/or SIP call restored normal functionality, but later the problem returned.
2. More recently, reinstalling the same build brought back the audio, but that didn’t last, either.

Call audio is still not working on my Sony.

EDIT: I should note that I’m using a different ROM now (not /e/OS), and although the audio was restored when I switched to the new ROM, the problem eventually returned.

Hi @aibd,

thank you for your answer.
I forgot one detail, in my description.
Most of the time, I can’t hear my correspondent but sometimes for no reason (no reboot, no change on anything) the audio works and I can use my phone normally.
That’s why I don’t think of an hardware issue (but I can be wrong about this).
I will check with the app Checkup just to be sure.
Thanks for the advice.

Thank you for your answer @xof.e.

I already check that possibility, unfortunately this is not resolving my problem.

[fab_m]

Thank you for your answer @Taurus.

I have already read the threads you share and many others (and you were present on many of them).
I’m sorry to read that you still have the problem (you seem to have spent some time looking for a solution, it’s not really reassuring).
Do you think it could be a hardware issue?
Which would appear from time to time

No. The earspeaker works just fine when using other applications.

Maybe the problem occurs when using Bluetooth/BT.

Possible fix: Developer options, switch off “Bluetooth A2DP hardware offload”.

On my OP6 when using BT to play music, I have to disable BT before a call and even than only sound on Speaker.

Or first switch off Bluetooth and restart. Don’t use BT at all.

(The same bug as in LineageOS21 for OP6)

In iPhone there is an option for calls to have sound through the phone speaker as default.

Calling via whatsapp is working.
