bluetooth phone call very noisy

[NeoTheThird]

I've no problem to play music via bluetooth on my car. However, i cannot get a decent phone call through bluetooth.

• I cannot hear decently the other person, his voice is highly disturbed an noisy.
• My voice seemed to be far but normal.

Same for legacy device Meizu Pro 5, it never actually worked properly. It would be awesome if someone could fix this annoying issue. On Android (e.g. Radio Meizu China Open 36) it works flawlessly, not any issue, but on Ubuntu it's a nightmare. Canonical said that it is a very complex issue, but I believe you could manage to fix this. Good luck.

I hope this bug will be correct, it's the only thing that missed me to use my PRO5 with ubuntu...

I broke my BT headset =( otherwise I could test on N5 and E5 as well...

It would be interesting if we post the bluetooth version of the devices that we are trying to connect to. I can confirm that my Meizu Pro 5 has the same issue with a bluetooth 2.0 headset but no issue with a bluetooth 3.0 headset. Couldn't this issue be then relayed to the bluetooth version?

I'm having this issue with Meizu EP51 headphones , It's version is Bluetooth4.0+EDR. by thier web site specifications : http://meizusale.com/meizu/EP51.html.

Just to add to the pool of the problematic bluetooth version

[mihaelmilea]

Oh, I see, then maybe it is not related with the bluetooth version...

One more thing in the hope that it will help identify the problem: my bluetooth 2.0 headset connects to the phone but when I play music that is still routed to the phone speaker and not to the headset. When I try a call that is routed to the headset but I hear only noise.

I did read on the xda forum website that to fix this they would have to update the android driver. I also did read that someone on the site fixed their pro5.

[Stefano0101]

I will try to modify the system.img with a new version Android drivers.

Let us know if you have any success...

I have cheap 4.0 bluetooth handsfree, model BL-V6. Same problem, very noisy and mumbled sound from caller..
Phone is Nexus 5.

I tested that same bluetooth handsfree with Nexus 4 (stable) and call sound quality is good. No noise and mumbling..

For me the same. The bluetooth headset WF-1000XM3 connects to the phone and the call is routed to the headset, i can hardly understand the voice, the noise is predominant. The music is not played on the A2D2 high fidelity or the phone port audio, only on the phone speaker.

With "pactl list" I could see the different sinks and you could change it with "pactl" somehow, i think.

The BT connections says it is still connected, even the headset is connected to another device already.
