Audio lag fix [solved] - Lenovo P2 Questions & Answers

Finally found a way to end audio lag in apps such as YouTube. After installing Viper4Android and thereby installing their audio driver, audio lag completely disappears. Just make sure to toggle the Master Switch to ON under each listening device tab you intend on using i.e. headset/ phone speaker.
Obviously you need to be rooted to use this method.

Wow! I was in doubt of buying this phone because of the audio problems. If the problem is as simple as proper audio driver, my choice will be easy!
Can someone confirm this?

Problem is that you have to be rooted to use it...

Lmao, P2 doesn't​ have any audio problems. It's just a small software issue that Lenovo are too lazy to fix! I recommend the phone with both hands.

Is the audio volume low during call? Or static noise during music playback from headphone jack.
Does viper fix all these issues? If yes in would buy this device...

My old Note 2, want to turn it into a media device for my car

Hi all. I have a spare Note 2 that I would like to turn into a dedicated media player for my car. Meaning, I don't care about any other apps really, just Spotify and my media player on the device itself.
Technically there really isn't probably much of a reason to root the device that I know of. Admittedly, I don't know anything about rooting a device, so I don't know all the benefits.
Having said that, there is one problem I'm hoping rooting will allow me to bypass. When I turn my note 2 volume all the way up, the connect to my car, when a song begins to play, the volume will sound loud for about 1 second, then all of a sudden drops several DBs. This seems to happen on both of my Note phones, Note 2 and Note 4. I'm hoping that rooting my phone will allow me to bypass what ever is happening on the phone.
I started to go through the process of rooting, one of the first things the instructions say to do is to backup the phone. I followed this h t t p : / / beginnerguides.net/android/how-to-backup-every-mobile-device
However, after starting the process, the backup software said it was unable to connect to my phone. Which I'm not sure why, Windows 10 sees the phone just fine in Explorer.
If I don't care about anything that's on my phone, is there any real need to perform the backup??? Can I just skip this step and move onto rooting?
Did you try to just use another media player? like Shuffle+ for example.
For car use, I recommend AutoMate Car Dashboard app, is really cool :silly:

i've tried an iPhone and a Windows Surface. Neither of those devices had the volume issue.

Try another music app like Shuttle+.
If this doesn't fix your issue, root and install agni kernel with boeffla sound control.
With boeffla you can bypass the android audio compressor and reach whatever volume you want.
ps: the volume drop you listen, is just a protection, the track is just loud.

Not sure shuttle will be what I want. I use Spotify, so 90% of all the music I play is through their player.
I will look into agni and boeffla.
Will these work on my Samsung SGH-I317?
Ok suppose a better question is, If I install the AGNI kernel, will I still be able to run Spotify?

I supposed you connecting your devices via Bluetooth. It is possible your phones to recognize faulty your connection with car as Bluetooth headset and lowering the volume for protection for your ears. There is a setting "Limited Headphone Volume". You can disable this at some roms at settings or at media player settings.

I was reminded last night why I even bothered upgrading from my Note 2 to the Note 4… The headphone jack is messed up on it. So, at this point, it does not even matter at this point unless I get that fixed.
As I was digging around last night, I read here at XDA that the AT&T Note 4 is unrootable.

Bluetooth Audio not working over Bluetooth headphones or speakers

Hello people...
I own a Bluedio T2S headphone which works with Bluetooth.
Upon connecting it to my OP3 it shows up as media and phone connected.
But whenever I play a track in any music player it doesn't plays any audio
I cannot play any track..!
I tried turning off all sound mods but still no luck the only thing that brought back the Bluetooth audio was a clean flash of the ROM itself.
My setup
OnePlus 3 on CB 3.5.3
ARISE sound mod.
Systemless root.

Bluetooth Headphones Issue

I have an issue with a new pair of bluetooth headphones i have just purchased. Specifically media playback sound quality. It is utterly woeful, with distortion, hiss, and cackles/pops continually over any media player or videos. Sound quality on calls is fine. I know that the headphones work, as i have used them on other devices and they function fine. My S9 is currently up to date.
I initially though that it was something to do with volume limiter as the weird thing is occasionally when they immediately connect and i play some music they work fine, then the quality drops as soon as the limiter notice pops up. I have checked though and the limiter is actually turned off. Turning it back on doesn't solve the issue either. I've gone so far as to wipe the whole cache partition and nuke all the caches, but that hasn't helped either.
Is there a known issue that I am unaware of ? Hopefully with a resolution, or other obvious steps i could try that people could recommend, as I am out of ideas now.

i flip back and forth between a few different BT headsets and never have this issue and have also used the same headsets on several devices in my bag-o-tricks. The phone does use a DAC for music where its pretty raw for the phone convo, which could explain why calls are ok, but music isnt. Is this your only pair of BT headphones? Do you know anyone who will help you test them on another phone?

I do actually have another pair of bluetooth headphones i use for my PC, i will try them with the phone tonight, though I am sure that the headphones themselves are fine. They work with my watch without any issues.

I have experimented a bit more, and think that this is a codec issue. If I enable the developer menu, and switch to another codec (not the SDC if defaults to) them restart the headset they work fine. Problem is that it always defaults back to SDC whenever the headphones are disconnected for a period of time. I can't see how to force the use of another codec, both AAC and LDAC for example work absolutely fine with the headset. Though this is quite a long process just to get the headphones to work each and every time i want to use them.

if im not mistaken, the default codec is controlled by the stack overflow. what version of android are you using?

I last updated 02nd August 2019. I have just checked again, and apparently running the latest version available OTA.
I couldn't tell you when the bluetooth sound issue started, as this is the first time in a long time i have connected any bluetooth headphones to my phone. I think previously connected the other headphones i have yet to check again, but am not certain.

gotcha. i also understand youre probably at work like many of us poor schmucks such as myself, which would make it kinda hard to test things out right this moment. But do any of your coworkers have a BT speaker you can connect to to try to replicate the issue there as well? Im mainly trying to eliminate variables at this point. You might try flashing the most current Odin files with the "HOME_CSC" as to not erase your user data. Itll over-write the code for the OS and so forth and nuke any software issues that might be causing this
I've now tested another set of bluetooth headphones and they work absolutely fine, they default into the aptX codec. Is that determined by what the device primarily works with ?

yes, the codec is changed by the DAC within the phone to be the best suited to whatever device its connecting to. What kind of headphones are you using that get the garbage sound? I have a pair of Tozo T10's, which are the off-brand individual ear buds from amazon for $50 and they sound very good. I also have a pair of maxsonic bluetooth buds which cost $17 that are connected to each other by a wire and they sound equally as good.

Bluetooth audio quality question

Hello. I change phones alot and have noticed that some phones(all android) have better bluetooth playback than others.
I had a oneplus 7 pro before this phone and the bluetooth quality to my truck was great and had no issues but with this phone the highs sounds scratchy or like if the speaker is bad. But if i connect it with a wire connection it sounds great. Everything with the 2 phones is the same. On both i was using the galaxy watch and pretty much the same apps. On a previous phone the note 8 i had the same issue but it was a different car. Seems like its the way samsung handles bluetooth.
Has anyone had this issue? If so was there a fix?
Thanks

What do you mean?
The only two things I think about is the codec used that may be different across devices, and the Bluetooth settings that sync the phones volume with the headset (the differences are noticeable).
Since no DAC is used in Bluetooth, I don't think it can comes from them, for a same headset.
On Samsung phones you should run the adapt sound process. Try this.
I tried with the sync volume off too and no improvement.
I looked for the adapt sound and my phone doesn't have that setting. Or is it something different?
It's in Sounds and Vibration 》 Advanced Sound settings 》Sound Quality and effects 》 Adapt sound
You have to do this in a quiet place and ensure to answer honestly. If you can't hear the beeping press no.
After doing this the sound quality is night and day difference.
Ok found it. Ill play with it a bit. Thanks
I've had issues sometimes with audio being piped through the "Calls" Bluetooth channel versus the "Audio" channel so worth checking as the quality is obviously night and day.
I also like enabling Dolby Atmos on my Note 10+ for music so worth playing with too. Additionally, I recently found Samsung's Sound Assistant app which let's you customize a bunch of sound settings so worth checking out as well:

Is there an easy way to tell if the audio is going through the call channel?

Easiest is probably just uncheck calls in your phones BT settings for your truck (and make sure audio is enabled). If the sound is still not great then this isn't the issue.
Sorry to respond to an old thread, but I was wondering if any of this fixed the OP's problem. I followed all the recommendations here and on other threads but have not been able to solve my recent Bluetooth audio problem. The sound has been terrible lately.
Same issue here on my s10+. When playing any audio in my car via BT i hear the distortion/hissing noise especially when the song has a higher treble frequency.
I have just about tried all fixes i could find on Google, and no luck.
When connecting to my ear buds (Jabra Elite 65t) it disappears and checked in developer mode that it supports to AAC for BT Codecs.
But when connecting to the car it reverts to SBC.
The issue clearly lies on Samsungs side, as my brother has a Huawei p30 Pro, also has bluetooth 5 and plays amazingly well in all aspects (Bass-Mids-Treble).
I know I'm posting this almost a year later, but i am desperately looking for a fix.
SN. I have recently updated my phone to Android 10, despite all the complaints to Samsung from many users... Sadly this issue has not being fixed on my side.
From what i see online, people have given up on Samsung and opted for Rooting their Samsungs and installing Viper4Andriod.
Has any one done this and can confirm that it fixed the issue?

Bluetooth CRACKING/POPPING noises!

Hello everyone.
Since 2 months I know have this "strange" phenomenon that when I connect my Realme 6 Pro to my Bluetooth sound device of my choice, for the first few times connecting there are only popping/cracking noise sounds coming out. No music or anything relatable. After connecting around 5-10 times, it finally will play music (also it suddenly goes back to the cracking state when clicking around in youtube).
Bonus: most of the time (even if connected right and playing music) the microphone wont work in calls.
I cant fix this sh*t and it really bothers me a lot lately.
Hopefully someone can help, or else I´m going to throw this phone into the trash can... xD
Greetings.
My BT works fine for the most part, but sometimes it breaks up. I am really hoping it's just a software issue
Me too, for about 2 or 3 months now. Wasn't a problem before. Thinking I'll try factory reset soon, see if that fixes it.
Hey! I also have this problem and what i found is, if your Bluetooth audio support Aptx codec, it will enable option "Use High Quality Audio" in your audio bluetooth settings. Try to disable (it will use SBC Codec) and my problem disappear.
But, it really annoying. I already try my bluetooth audio with another phone and it worked fine with Aptx, so i know my bluetooth audio is not my problem. My workaround so far are disable high quality audio, then enable Aptx manually in developer options with AVCRP 1.6
Not sure if my device actually using SBC codec or Aptx after change it manually on developer options
Hi All! I solved problems with Bluetooth by switch off Dolby Atmos!
