I would like to install GrapheneOS but not before knowing for certain that it supports ASHA (Audio Streaming for Hearing Aids). The android documentation is found here: https://source.android.com/docs/core/connect/bluetooth/asha
I believe it's part of AOSP and so should be part of Graphene, but I'd like to hear from someone who has tested it and confirmed that it's working because it's not advertised anywhere.
