Hi Paolo. Same problem here with Bluetooth. More data:

- I have experienced this problem with both beta5 and beta6 and Radio 3.70. I don't know if with previous beta version since last time I used bt link for music I was running CM12.1

- This only happens with music. Not with handsfree device.

- I have tested with three different devices: logitech, amp and a chinese "enjoy" device. All with the same problem.

- Tested from Spotify and YouTube apps.

When listening music songs are choppy. Link is established but its impossible to hear a constant song for more than a second.

I will test with previous basebands.

Confirmed. It is a baseband issue. With 3.60 no problem
I will check all until find newer one without this issue!!

So, is there a database of baseband zips anywhere? I'm searching and can't really find any. Does anyone have 3.60 or 3.62? They're the newest ones that appear to be stable.

Look at first post. In baseband link, Paolo has a full recopilation at Mega.
I can confirm that 3.65 also works. I will test this afternoon 3.68 and 3.69 to find where ZTE broke Bluetooth. ;-)

Hi everybody.

Regarding Bluetooth audio problem, definitively it's a Baseband bug.

Baseband from 3.60 to 3.67 do NOT have any problem with Bluetooth audio.

Baseband from 3.68 to 3.70 do HAVE this problem.

So, if Bluetooth audio is a must for you (for example in my case) do not use Baseband newer than 3.67.

Hope ZTE solve this issue in next Baseband releases.

Paolo, perhaps could be a good idea warn about this at first post. Feel free to transfer this knowledge to Italian forum, of course. ;-)

I knew it was somewhere but I guess I'm going either old or blind. Thanks :D

Hello, Paolo, beta6 seems to be a problem After the restart,the 4G network will become the 2G network, you need to manually change the manual into the network priority options.

More info:

- I was able to reproduce this issue with baseband 3.67 and 3.62. After several minutes working well audio output started choppy again.
- Same behaviour that in 3.68 and later baseband.

I think this is not only baseband related. There must be something else at ROM level, I'm afraid...

@inigoml thanks for the report and tests :)
I have reported your conclusions in the Italian forum here

for those looking for the baseband zip: all baseband zip

maybe I fixed the problem (kernel related)
now I have the baseband 3.70 and bluetooth seems to work well
I do more testing :)
