We/I need the driver from 4.2. In 4.3, the alarms, notifications and ringtones go through internal speaker. My internal speaker will NOT wake me up in the morning, that's why I have bluetooth speakers, but in 4.3 all i can use them for is music and video soundtracks - even so, the audio over BT on 4.3 is awful and not as loud as in 4.2. (tested on both 4.2 and 4.3)
So we want the fancy 4.3 but with the decent 4.2 driver. Can anyone manage that?

[Q] Bluetooth Headset Call Issue

Hi!
I have problem with Bluetooth Headset when doing a call running CM11 based rom. When I started a call I cannot hear the one I'm taking to also she cannot hear me speaking. I have a Samsung Stereo Headset and it is working on Stock TW Rom. Is this a common problem for cm11 rom?
The Music and system sounds are working and I can hear it except the talking part during call. Any solution if there was one?
Many Thanks!

increase BT Headset mic volume for outgoing call possible?

Hello,
i have the Xperia Z3compact for over One Year.
I'm on the road every day, so I use the Sennheiser Presence Bluetooth Headset for any call.
My only Problem is when calling; other's hear me to low! They have to increase their speakers to maximum and had problem to hear me. The Sound Quality is very good but they here me too low.
I have tested every Rom from (original) Android 4.4.4 over 5 Lollipop Versions (stock and rooted Rom's) and now on the newest Sony Android 6.0.1
-all with same bad results
When I'm calling with the Phone (without Headset) all here me perfect and loud.
But not with the BT Headset!
Then i have tested Cyanogenmod Cm12.x and wow the Problem with Bluetooth headset is completely gone
All here me loud and perfect!
But on CM the camera Quality is gone and I have the fisheye problem.
Now the big question:
why is the BT Headset outgoing mic volume louder than on any other Rom's?
And is there any option to increase the Bluetooth outgoing mic volume with a rooted (stock) Rom?
I know about the mixer_paths.xml file.. but no one ever, write here; How to tune the Bluetooth outgoing Mic volume!?!
All only tune the z3c inside mic's and speakers..
CM Mod is nice but buggy there is no stable Version and the cam quality is crap.
So please, if any one have a idea what I can try? to increase Bluetooth Mic Volume!
Help me!
Information:
The Problem is not my Hardware...
I have tested the Bluetooth Headset with other Smartphone without problems!
I have tested the Headset with another new Z3compact -same result other here me to low on BT Headset Calls.
So there is no Hardware defect.
PS: Sorry for my bad English.
Hope someone can help me

Stereo Sound Recording

In previous version of Android(9 Pie), I was able to record the audio in stereo mode. After android 10 only able to record mono sound. Is it Device issue or Recorder App issue?

Solved: Audio Crackling when trying to record on apps like RapFame, Smule or Voloco ☹️

Hello people.
I just bought this Asus Rog Phone 3 Tencent Edition with Global Rom installed, and it has the new Firmware Version WW-17.0823.2009.99.
I noticed that audio on speakers and headphones work fine when listening music or making calls... but...
When i try to Record something on Audio apps like "RapFame, Smule, Voloco, etc", sound on speakers or headphones is always crackling.
When recording voice in the Recorder App that comes with the phone, it works just fine.
I don't understand why audio is crackling on other apps.
I also noted that if i try recording on those apps without headphones, turning Outdoor Mode On "making Audio Assistant turn off", the recording works fine, with headphones Audio Assistant gets back...and the crackling comes back also.
So... Maybe the problem is the Audio Assistant in this latest firmware update?
Please help me, as one of the reasons i bought this phone was because of its great Audio, but now i'm sad that i can't even Record something in it because it's always crackling ☹.
Best Regards,
Bruno
Problem is fixed in the latest firmware update Version WW-17.0823.2012.122 available since this 23 December , now everything is good with the phone hehe .
