Bluetooth audio problem - Xperia Z1 Q&A, Help & Troubleshooting

Hey guyz i need to share my problem with you guyz.first of all i would like to say 136 firmware is the best till now but only there is one problem i am facing since i upgraded. Whenever i am playing the audio in my car audio system which have bluetooth functionality the audio gets broken sometime and it came again after few seconds but the thing is there is no problem when i am listening to the headphones or loud speaker, this problem only occurs while playing audio through bluetooth.
Plx guyz let me know if there is a solution for this issue

If you don't have problem with other devices that mean is the Car Audio causing the problem, not the phone.

Dude i am not saying that i checked with other bluetooth devices. I jus said i checked with load speakers and headphone jack not with any bluetooth device except car sterio. And by the way it was working very good with 4.2.2 m using since 4 months

Flash the "Baseband" only from 4.2.2 on 4.3 with Flashtool.

Are you sure 4.2.2 baseband is related to this problem? And baseband will work in 4.3?

If I am not wrong Baseband is a package with all the radio frequency needed for the phone to work properly. BTW, you can flash back the baseband for 4.3 in the same way.

Downloade the right 4.2.2 FTF, the one where bluetooth was working, and via Flashtool exclude everything except Baseband and flash it on 4.3. It will work, this was confirmed by users with weak radio signals.

Thanks ill try it tomorrow again

Hi,
Did you have any issues with connecting your phone to the car audio and making handsfree calls on .290 and .136? Because when I got my phone (running 4.2.2 and .257) it worked ok. I was able to make and recieve calls through the bluetooth using the handsfree of my car audio. When I upgraded to .290 (and also .136) the car would pair with the audio but the handsfree facility did not work! I "downgraded" back to 4.2.2 (.257) and it now works again.. I was wondering if I could use the method that you used - i.e. flash .136 and then flash the baseband of .257.
Regards,
Alan

Why you asking this again, I already told you in other thread to flash the baseband, why you downgraded the whole System? If we confirming you it's working the question is useless.

I havnt tried using phone with my car sterio because i dun like to receive calls in ma car audio system..
But im sure it will work aftwr flashing old basebands

Hi eclyptos,
I just thought that I would ask the original poster.. As his issue was different to mine..as in his was a problem with streaming music.. Not a problem with the handsfree making phone calls via the car audio system
Sorry if I duplicated my question..

Alan

edit the build prop?
Code:

I think if you calibrate the sensors this can help. Type *#*#7378423#*#* on keyboard and calibrate all of them.

I cannot find the values in build.prop
I checked with the its not calibrating the sensor and showing me the -99 error

[Q] microphone only work with camera

hi
Its my first post here and i will try to explain my problem.
I have a note n7000 wich have an out of order sim support. Its not a problem for me because i use it as little tablet.
I tested some kernels and rom from xda and i actually use crash rom v10 with 240 dpi mod and speedmod kernel v13.
Since a couple of day i try to use s voice and others but it seems that no sound is recognize. It try soundhound and same problem.
Vocal memo included in the rom doesn t record any sound too.
So i thought my micro was out but it works perfectly in camera mode.....
Does any one have an idea ?
Have you tried microphone operation with a headset? Best to rule out where the problem lies.

With headset microphone all seems to work normaly.
Without headset skype and video are working well.
With the microphone headset, in soundmeter apk the initial sound level is about -8 -9db and it move normaly to 50 or 70 db when talking or whatelse.
Without the headset initial value is at -50db and doesn't move....
Using camera with headset get no sound in movie.
I don't understand anything.

The fact that it's working fine without headset on Skype suggests its not hardware related. What rom are you on?

That's the reason why I stay on cm10 last nightly. Kowalsky kernel adds the last bit of fluidity to the Rom. Perfect

Sound is great but Bluetooth audio and call do not work. I tested with my SBH50 and MW1.
Works almost perfect except for one major flaw. Bluetooth call handling doesn't work on my ZR. When a call is made or received, there is no audio. I can't hear what the other party is saying. Please fix this. I'm using stock jb 4.2.2, and the Bluetooth headset I am using is Sony smart wireless headset pro.
Otherwise the mod is great.

The dev of this mod wont fix this bug because he does not own any bluetooth headset This is PureXAudio mod for Xperia Z and it also works on ZR.

Weird fact, i've Just try with the 3 modes (auto, manual 720p &1080p) no more audio recording lag... Maybe a random issue because this happen a few times. But at this moment it work I don't know why. I'll come back if this persist or if someone have the same issue =)

I don't know how baseband can improve the quality recording, are you sure about that? I know the baseband is the Radio Package for Z1 like Bluetooth, Network and WiFi.
Give it a try if there was no problem in older version then may be its the same issue with the baseband

[Q] Sound Bug After KitKat Update

Hello, i recently updated my Sony Xperia Z1 Model No: C6902 with the latest kitkat update but after the update their is disturbances heard in the message notification tone....what shall i do? is there a problem with the update itself?
Maybe, to early to say if it is a bug, some users have to report it as well too. Try Factory Reset first, it will wipe your data but it will clean up after update.

Do you have any mods installed that may have restored with titanium when you reinstalled the rom?
Could be that something is not playing nice with the new base.
Attempt a clean install with no restores and test the audio, then restore and if it comes back after the restore you'll know if it's a rogue app / mod or not.

I as well am having the same issue. The notification "skips" if you will at the beginning first 1-2 seconds of any notification. I have not noticed if this issue is present in a phone ring yet, only in notifications.

Shahzaib.khan I don't believe your referencing the same bug we are discussing. If I'm not mistaken your discussing the sound through the internal earpiece instead of the loudspeaker. We are referring to a notification tone which skips when being played during an actual notification

Same annoying problem here. Stuttering notification sound and sometimes the ringtone gets really low (10%).
Only a reboot fixes the problem. But after after a few hours it's back again :crying:
Guys i guess i was right at the first place
I comeback to 4.4 from the start
I flashed xperia ultra firmware which is modified by nut then i put 156 of xperia z1 then i root it and flash recovery on it and then formated every thing except external card, i formated internal memory also. And yes till now received 5 calls there is no problem...
Try it every one

Hi,
Is this problem solved now for you after the update to .757?
It hasn't for me. I still get the annoying broken/disturbed notification tone many times even after a clean install of the FW .757.
I am on stock ROM, non rooted. I really do want to know which app is playing rogue, if it is an app. I thought after the few updates to the walkman app, it may solve the issue, but it didn't.
