Hi,
2 Days ago there was no problem with my phone mic. But suddenly, mic isn't work anymore. I can't record voice or talk with someone on phone. Can you please help me about this problem. İs it hardware or software problem?
Thank you very much.
Hi @okolay,
I'm sorry to hear this. 
I recommend that you test you microphone in your devices built in diagnostics tool to see how it behaves there. You can do so if you go to: Settings > About phone > Diagnostics > Test > Microphone. Is it showing the same behavior in this test?
I would also recommend that you restart your device to safe mode to see if this behavior is caused by one of your downloaded apps as these will be temporarily disabled in this mode.
If there still is no change I'd recommend that you perform a software repair using Xperia Companion. Note! This will completely reset your device and it is highly recommended that you create a backup prior to resetting your device.
Keep me posted how it goes or let me know if anything I've written is unclear. 
Hello Emil,
I bought Xperia xa1 ultra few months ago. I am facing the same problem with microphone. At first, the problem was sporadic. However, recently after updating it to Android 8.0 the problem has become persistent.
The microphone works if I use it (i) with loudspeaker, (ii) connecting the headphone or if (iii) I charge the phone.
I have followed all the steps you have mentioned but no good result. I am really frustrated with it now.
after the new update i can record my voice with wassup or i can give a voice comend but still there is no voice the person's phone i talk with. I mean i mic is working as a recorder but cant use while i talk with phone....
Hey okolay,
are you sure, the microfone issue isn't a hardware problem?
I had exactly the same situation with my old XPERIA T3 STILE and it was a hardware problem.
That could be the reason why u can call someone but your talk partner isn't hearing anything.
Hi, what did you do to solve this problem? I have the same problem with the microphone, at 3 weeks after buying the equipment. Q disappointment. I have 2 months that I have the equipment and sometimes it works and sometimes it does not. Only with headphones or in a loud voice. I took it with the provider but it worked at that time for my bad luck. How can I fix it, Thanks
Hola q hicieron para solucionar este problema. Tengo el mismo problema con el micrófono, a la 3 semana después de comprar el equipo. Q decepción. Tengo 2 meses q tengo el equipo y a veces funciona y se veces no. Sólo con audífonos o en alta voz. Lo llevé con el proveedor pero funciono en ése momento para mi mala suerte . Como puedo arreglarlo, Gracias

Does the mic stop working while on a call? recording video? or using a third party app?
