I'm trying to use my Meizu Pro 5 Ubuntu to connect to bluetooth car systems for making phone calls. Previously I hav a system based on Windows CE 6. When I had connected to the system and made or answered a call I always heart a lot of noise and distortion. I was just able to recognise the voice at the other side of the line, but not able to understand and words. My old HTC HD2 worked fine on that car system.
I recently got a new car with a Pioneer multimedia set in it (F960DAB). I was hoping and expecting that bluetooth would work well now. Unfortunately I still have the same problem (noise and distortion).
I also had the problem of answering a call and the car system would still ring while the phone had answered the call already.
I upgraded the Pioneer to the latest firmware/bluetooth version and still had the same sound problems. At that time I also had the disconnection problem reported in other bugs, but when I told the phone to forget the system and re-paired the connection was constant avalable again. The sound is still big noise and distortion. Our Iphone works fine on the Pioneer set.
My phone uses Ubuntu 15.04 (OTA-13).
Same issue with my Meizu Pro 5 (OTA-13).
Tried both Sony MBH10, and car handsfree as well.To both of them the phone is connects withouth an issue, the music playback works great, but phone calls are distorting not being able to understand a word from the other side.
