I have a similar problem on Meizu Pro 5 Ubuntu edition (Factory installed). OS - Ubuntu 15.04 (OTA-10.2) I have a "Ford B-MAX" (built in 2013) with factory built-in "SYNC" hands-free. Phone properly paired, properly synchronize phonebook. I can dial a phone number and I can answer on call using the car's control panel buttons. But it is impossible to talk using the built-in car hands-free system, because of the terrible hissing and speaker's voice can not be understood when the car is in motion or absolutely silent when the car is stopped.
Addition problem - Ubuntu phone does not support SMS writing-reading and SMS text to speech playing in my car. This functionality is fully supported when I use phone by Android version 4 and higher. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1546310 Title: In CAR bluetooth not working Status in Canonical System Image: Fix Released Status in bluez package in Ubuntu: Invalid Status in pulseaudio package in Ubuntu: Fix Committed Bug description: I have paired my phone with my car as always (connection did work in the past).
