[sound] Microphone is disabled because of calls
During calls, the microphone no longer works, likely not the fault of the "Calls" program, but the sound profile(?).
I don't do phone calls too requently, so sadly I can't pinpoint when it went wrong, but it's been like this at least since October 1st.
By default when the setting says "Play HiFi quality music", the mic works (at least the bars move when I gently knock the underside of the phone). See image
But once it gets changed to "Make a phone call", the bars no longer move, they remain a constant 2 (and a half?) bars. See image
When setting gets changed back to "Play HiFi quality music", the bars remain static and no longer change. See image
