I know this is an unorthodox question, but I have too many family overseas that use WhatsApp and I would like to be able to stay in touch with. On the Pixel 4a I own, I can use WhatsApp for the most part with GrapheneOS, but they cannot hear my sound on voice and video calls. I tried calling my wife with WhatsApp and this seems to be a consistent behavior: she cannot hear my voice. Video transmission is normal. I tried muting myself and unmuting again on the app, I checked WhatsApp's permissions and confirmed that it can access video and microphone with no avail. I would appreciate any help for troubleshooting!
