Fairphone 5 – problem with calls – no sound / no microphone

I moved from CalyxOS to IodeOS on my Fairphone 5. The manual installation worked fine. So far everything else worked fine.

The eSIM in the FP5 was connected to 5G right after the installation. All permissions are granted. I can make calls and receive calls. I also get the connection sound for outgoing calls. But the voice part does not work, so I don‘t hear the other side and the microphone doesn’t work either. Trying an alternative phone app resulted in the same behavior.

Further observations:

  • The microphone works in the recorder app

  • Calls with Signal and Threema work in one direction only (microphone does not work)

  • BigBlueButton conferences don‘t work as well – both directions

  • Sound playback via browser and radio app works

I searched for the problem but didn’t find any helpful results. Would be great to get some feedback how to solve or debug the problem.

Good news!

I just received and installed the update to iodeOS 7.2. Now the issues are solved. :slightly_smiling_face:
