Sound completely gone

Hi all,

since this morning i have no longer sound on my Fairphone 6.

e/os: 4.3-a16-20260917677552-official-fp6

What i tried so far:

  • connect bluetooth speaker
  • try sound in different apps (browser, music player, netflix)
  • restart in safe mode
  • restart multiple times / shutdown + start

what else can i try? there was no update i’m aware of, it just stopped working today. I also did not install a new app or something.

Also when i try to phone i can’t hear anything and also the other can’t hear me. After 5s the connection aborts.

Also disconnect the battery for a few minutes, didn’t help.

Microphone also does not work (started a recording, but playing it on pc does not play sound)

update:
adb logcat shows these errors multiple times:

E gsl: Graph open failed:1
E AGM: Failed to open the graph with error -131
E PAL: pcm open not ready
E PAL: stream start failed. status -131
E AHAL: failed to start stream. ret=-131
E AHAL: write error -22

update2: i did a factory reset - still no sound. Will send it to fairphone.
