I’m using Droidian on a Vollaphone 22. After flashing the phone, normal audio calls work out of the box. But after a day or a few, I can’t hear anything while making a phone call, and the person on the other end likewise. The same goes if I receive a call. Only a faintly low frequent buzzing is noticeable on both ends. What I tried / checked to get it working again:
- Sound works in general. I can test the sound, and I hear the phone ringing when Feedback settings for Calls and Profile is on Full
- If the other person hangs up I hear three beep, beep, beep
- VoIP accounts are affected too
- Doesn’t matter if output is to earpiece or speaker, both don’t show any effect
- pactl settings checked, and changed quite a few, but with no effect at all
- Rebooted the modem:
sudo mmcli -m any -rwith no effect - Rebooted the phone
- Turned the phone off and removed battery to be sure the modem doesn’t hang
- Set modem specifically to 2G, 3G
- Tried droidian version 101 and 102
Nothing had any effect. I’m always ending up flashing my phone again after a few days. Then I can make calls again. It’s frustrating, because I know in general it’s working, but the error here is none obvious.
Does anyone had similar issues? Or maybe just some ideas what could go possibly wrong? Sounds to me like a problem with pipewire routing, but that’s just a guess.
