Dear GrapheneOS community,

I recently switched to GrapheneOS with my new Pixel 9a. All in all it works well, but there's still one or two things I just cannot get to work.

Whenever I start GPS navigation, I can hear a voice saying a single sentence and then just stopping and silence for the rest of the drive.

I tried the following apps:

• Osmand
• Organic Maps
• CoMaps

I have installed RHVoice as TTS software.

When starting navigation, Osmand tells me how long my journey will take and how much distance I have to drive and that's the last thing I ever hear from Osmand voice navigation.

Organic Maps navigation tells me the first thing I need to do on the drive (e.g. "turn right in 400m") and then not a single word for the rest of the drive.

CoMaps seems to be the same.

If I enable Osmand Development Plugin in Osmand, I can then test voice output, which works perfectly. It just does not work when I need it and I have no idea why.

Does anyone know what I'm doing wrong?

[EDIT]

If anyone comes here from google or somewhere to find help, I sadly have no solution to present. I just gave up and uninstalled all navigation / TTS apps.

I tried different navigation apps, so it isn't a navigation app problem. I tried different TTS engines, so it's not an TTS engine problem either.
