I've been using GrapheneOS for a while now - mostly without problems. However there's one issue that I can't find a solution for:
I'm using an application called Calimoto for planning and recording motorcycle rides and there's the functionality of navigation by voice.
However, this doesn't work on GrapheneOS (on another Android phone it does). There's a "test" button for the voice output in the app which also doesn't play any audio when pressed.
I have given the app any possible permission and reinstalled the OS, the app with Aurora and even the mirrored Playstore but to no avail.
A friend told me that he had the same issue with Kurviger (which is an alternative app) on GrapheneOS that he was unable to solve.
Do you have any idea how I could solve this problem? Please let me know if you need further informations related to this issue.
Thanks ahead!
