Hello Guys,

I did some tests about bluetooth and I would to share some results for help in solving this annoying bug.
I have a Meizu pro 5 with 15.04r3and as I said before with Bluetooth Music Player is working fine but calls sound is disturbed.
I realized that:

1. Music Player comunincates with bluetooth headphone trough a2dp_sink (ACL) protocol;
2. SCO (HSP/HFP) protocol is not working.

I did some modification to the file:

/etc/pulse/touch.pa

I commented out the load of the two module-null-sink and I modified the module-bluez5-discover
in the following way:

load-module module-bluez5-discover headset=both

With this modification I tryied to reproduce some wav tracks with the tools paplay in this way:

pactl set-card-profile <bluetooth card number> a2sp_sink
paplay -v -d bluez_sink<my bluetooth card macaddres> tracks.wav

Sound it's ok, and with hciconfig I saw ACL TX packtes growing, in this way:

pactl set-card-profile <bluetooth card number> headsset_head_unit
paplay -v -d bluez_sink<my bluetooth card macaddres> tracks.wav

paplay hangs and with hciconfig not packtes are sent. So I apply this patch to broadcom bluetooth chip:

https://freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Bluetooth/

hcitool cmd 0x3F 0x01C 0x01 0x02 0x00 0x01 0x01

And I try again to reproduce the track with this command:
pactl set-card-profile <bluetooth card number> headsset_head_unit
paplay -v -d bluez_sink<my bluetooth card macaddres> tracks.wav

Finally it works and with hciconfig I saw TX SCO packets growing.
Then I try to start a Call with telephony-service but not sound!
Can you say me which is the default sink for telephony-service??

Conclusion: I think that the sound it's disturbed because OFONO packets are sent to "bluetooth haedset" with ACL protocol and not SCO protocol as it should.

I hope that this can help you. I continue to debug the problem and I hope to find a solution.

Best Regards

Hi,
i've a meizu pro 5, bluetooth is working fine with my music app but no with phone app, I hear a lot of noise and I notice that bluetooth speaker controller doesn't come up when I try to adjust volume with the physical buttons during a call. Is it possible that phone app doesn't use the right audio device during bluetooth connection?
thanks

Hi,
thanks for ubuntu touch, I had same problems with a meizu pro 5 with flyme 6.0.0G firmware installed. I solved installing previous flyme firmware from here:

http://dl-res.flymeos.com/Firmware/Flyme/PRO_5/5.1.11.0G/intl_stable/20161028020453/22a9e4dc/update.zip

then I installed beta firmware from xda developer site and I unloked the bootloader.
