[MX4] Sound output (try to use it as hands free set)

[Krzysztof Tataradziński]

Hello,

On android, in car, I'm connecting phone to car audio by mini jack.
When someone calling, I use hands free mode - audio output is coming from car audio and mic input is better. On Ubuntu, when I don't click hands free, audio output is coming from car audio (that's good), but mic works poor (like in normal phoning). When I click hands free button, mic input is very good, but audio output is coming only from phone speakers (and it I think it should like in android - from car audio).
