poor audio quality via Bluetooth : audible distorsion - Huawei P9 Lite Questions & Answers

Hello everyone !
I recently bought a P9 lite VNS-L31 and I noticed that audio quality is not very good through a bluetooth headset or a bluetooth speaker when I listen to music. There is some distorsion and it's audible and uncomfortable. I tried to connect various bluetooth audio devices to my P9 lite and the problem is the same. I also tried the P9 lite of a friend, there is the same problem. But there is no problem when I connect my bluetooth headset to my previous phone or to my computer...
Does anyone know this issue ?
Thanks a lot

Never try headset, but BT speaker is working well ,no distorsion ( for me ) maybe you can try an equalizer or somethink like that. I use bass booster ,you can set / adjust your sound. You can get it from play store, no root needed.

Hello !
Thank you for your answer I just tried bass booster but it didn't solve the issue Actually the distortion can't be heard with all musics... For example with this classical song, the distorsion is very present : https://www.youtube.com/watch?v=GRxofEmo3HA
Do you see the problem with this music ?
Thank you in advance

not possible yet, I'll try asap

I have a Plantronics BackBeat (a bluetooth headset) ans I have no music distorsion at all. Did you changes something ? Like activated sws or something ?

Hello everyone !
Thanks for your answers !
I didn't change anything in my settings. SWS is not available with bluetooth...
Maybe you can try the 2 songs attached to this message. With my P9 lite through bluetooth, the distorsion is clear, and more audible when I turn the volume up a bit. It's like a saturation, or an audio interference in the song.
Does anyone see the problem ?
Thanks in advance !

No distortion for me. I've played your files through bluetooth on my hi-fi system and sound is good.

Hi,
I have this exact problem too! When I use my old phone (LG G3) in my car throigh bluetooth ghe sound is crystal clear with good bass. When I connect my P9 lite the quality is awfual, distprtion, loud crackling bass, the treble fluctuates and I have not yet found a solution to get it to the same quality level as my G3.
It ses like there is some sort of preset interal equaliser, but I can't find a way to access it.
Any ideas?

In my opinion, if you are using your phone as your primary source for music playback there is absolutely no way around Viper sound mod. Of course this requires root and permissive SELinux access.
The audio on this device was indeed not good with stock settings. But with the right settings and IRS in Viper it is a blast.

Hi Jt94 !
I am reassured to see that I am not alone in this situation Do you hear a little "tchhhh" like an audio saturation while listening the 2 songs I uploaded yesterday for example ?
Does someone else have the same problem ?
Thanks !

I've try your youtube link, and some others songs from my play list, with my bluetooth speaker, using Poweramp and no problem report. I use BT adapter in my car with stock player, I've got some trouble sometime but ithink it's coming from my tuner.

I using spotify. At first I thought something went wrong with my Sony MDR-XB650BT headset. And tried from PC, and everithing is okay.
So I hear this "noise" continuously too. I hope to the manufacturer will fix it. It is very irritating.

I sent an email last week to [email protected] but I still have no reply...

I have the same issue , I tried a wipe data cache and a factory reset but non of this works. Anybody have new information about this issue and how to fix it?

Do a full factory reset. Try it maybe it will solve your problem.

I'm using my Bluetooth Headset everyday and i also have zero problems. perfect sound for me. (cheap mixcder ShareMe 7 BT 4.1 headphones, but good sound for the price ;D - and long battery life). maybe your device is faulty?

Hi,
I have a VNS-L31 with the same problem.
I think it's related to A2DP codecs on Bluetooth: the SBC codec is a poor quality compression that must be available on all devices while AAC, MP3 and aptX are not always present.
However I don't know how to force the use of high quality codecs.

A2DP working at Trinity

I prepare to buy Trinity very soon and knowing it should support A2DP bluetooth music listening in good quality.
May anyone of you give me idea if the A2DP works fine. I hear someone says the A2DP is at mono sound in playing song. Is this true? Pls advise.

I didnt try it ... but i read that you can switch to stereo with a registry setting.
I know that registry, using UseJointStereo=0
Just want to know if this works eventually.
work perfect
Hi everybody,
This is my first message in this very interesting forum.
Just to say that on my TnTy this does not work...
I MUST instead set to 1...otherwise I have the bad and noise sound effects described in another thread...
even changing BitPool from 30 to 48 or 58 do not have so much difference in improving the sound in my iTech Blootooth Headset...
But the final result is that the Stereo sound is VERY GOOD anyway

Can anyone try A2DP?

I was wondering if the audio quality and sound stuttering has improved by using BT stereo headphones with Blackstone...
I have a trinity and i still haven't found a setting nor a rom nor a BT stack which handles my samsung headphones with a decent quality and no stuttering...
My cheap nokia 6234 has a solid connection and a good quality sound compared to the trinity... Plus, the A2DP connection slows my device down so much you have to pause if you want to do anything with it...
So if anyone could report about using bluetooth headphones with Blackstone, I would be very grateful as that would help me decide whether to buy or not
Thanks a lot

Great
I have the Touch HD for a few days now with the BH S100 HTC bluetooth headset. I have to say that the sound quality is great. It is even better than my conventional mp3 player.
Stable, never lost connection, etc.
Hope this helps.
I tried it today, with my Sony-headset.
It seems to stutter, though, for the five minutes I tested.
I have the Blackstone from seven day and the A2DP is OK with my Sony_Ericsson HBH-DS200.
The sound is very good and the pairing with the phone is immediatly in about 1 second.
Regards
reasonably OK with my Jabra BT620s. However, quality in BT A2DP is not really comparable with wired headsets, and i got some losses when passing nearby EM sources like wifi, etc.etc.
I needed to enhance the quality with Schaps Advanced Config Tool.
Alpine radio
I have an Alpine radio with bluetooth capabilities in my car, and for the first time I have a great connection with my HD. My Touch Diamond stuttered.
Thanks a lot everyone!
I guess it depends by the headset model and interferences then...
I'm still looking for a shop which would make me play with it for a little while...
i have a pioneer deh 700bt and the headunit set up was easier than the nokia n95
streaming music was a bit weird, the quality was very weird, kinda like very low bit rate streaming on mp3s at times, then fine again.
my n95 music used to pause when i took the key out of the ingnition and the stereo turn off
however the HD just keeps playing, but not through the speaker phone....just see it still playing
bit disappointed, and looking for a fix
I've only played for 10 mins, so i'll let you know if i find some more.
I have an Audi A3 from 2005 with a original BT carkit.
Can I use my HD to play some music ?
I can make phonecalls without a problem, if I adjust the volume of my carradio the volume from the HD is also adjusted.
But is there a possibility to play some music ?
Has anyone tried the Plantronics 855 Voyager stereo headset yet?
Also, I'm currently using the Jawbone 1 and noticed horrible interference/noise in the ear piece when the wifi is on, anyone else experience this?
I've never had any problems with the diamond and now with the hd. Like the senior man said, you need to increase the bluetooth bitpool values either in the registry or by using schaps tool. The difference in quality is immense - low values will make high bitrate music sound 64 kbps so you need to change this. Of course, the higher the bitpool the more chance of dropouts but I run at 60 and rarely, if ever have any dropouts.
Sennheiser MM200
Now if tested for almost one day my HD with my new Sennheiser MM 200. Amazing!!! The use of the MP3-Player switched with the use of the remote control to a new level. During sport display can be switched off(no need for touch display-less power consumption (try to give a more compareable info in future)), full control of play/pause/fwd/rwd/volume function. There is no delay of the HD in using the remote nor any transmission interruptings. Now the HD is with armwrest a perfect sport companion. The sound of the earphones - haven't had any better sound (and i've tried a lot of earplugs). Neckstrap fits perfect, mic in perfect position, clear speech and due to perfect noise reduction of the plugs even in noisy areas perfect understanding.
The Sennheiser was just charged the first time - i'll report the stamina.
So far -
I am using the i.Tech S35 bluetooth clip also on my HD now, and sound is very good, with WiFi on. Advantage of the clip is that one can use any headphones with it.

HTC HD2 + Jabra BT3030 (bluetooth stereo) = too loud

Hello,
Today I paired my HTC HD2 with Jabra BT3030 bluetooth stereo headset. Everything seems to work fine except a little issue - even with minimum volume settings a sound comming out of headset is faaaaar too loud.
Maybe you know if there's any fix for that? Of course setting volume on the phone does not bring any results. At this point listening to music with BT3030 kills my ears.
Regards.
i'm also thinking about buying this headset... any1 else have this problem?

Same issue, it's too loud :-/
only solution till now - use a SW-Equalizer...
hi I have the jabra headset you have and the volume is just about perfect. maybe it could be to do with the ROM you are running and the region you got the phone from! I got my hd2 in Hong Kong and it came with 1.48 ROM preloaded. I do remember seeing a different thread with other people with the same problem as you on this forum. I also sure I sas some other threads on this board where people were looking for the registry weeks the raise the volume limit, but everything that is tried does not work. I hope you can sort your problem soon as the jabra headset is pretty good and the sound quality is very good.
I have the same equipement and I love it.
You can´t adjust the loudness via phone. You need to manage it via the bt receiver itself.

Right. There is a +/- which is for volume.
I reduce it every time because my In-Ears are very loud either.

yes same here. there is only one issue with the volume buttons on the device itself. everything else is great...
I have the same problem with my HD2 and Jabra BT3030.
Sound is too loud from earphone can't adjust in "HTC sense media player"
I tried Coreplayer and media player without this problem.
Today HTC informed me that maybe the devies are not compliant and I should take a look at www.htc.com for accessories. Amazing!!!
That's pretty sad that there is no registry tweak to fix that.
P.S.
I have 1.48 WWE

I think I know enough... HD2 can't handle bluetooth headsets like the BT3030, I will return this product, and ask my money back
Strange... hard reset + BT3030 replacement (because one button was malfunctioning) = no problem. The minimum volume is in my scale "normal volume". It's not very silent, but fine for working and tripping.
The problem is known and seems to exist only in htc music player

I guess HTC Sense Music Player is not compatiable with some BT headset.

Hi
I use SRS WOW for equalizing and I have no problems with bluetooth?!?
Using SRS WOW you can set the output gain level, so it's not too loud anymore! Till now the only solution I know...
I've different problem with BT3030
i've found that when recieve any phone call, sound too low so every time to call or recieve must press volumn up every time like Sound Volum Level can't remember by HD2, never found this problem on htc3470.

Hi!
Today i got my BT3030 and works fine with my HD2.
No problems with the volume. The mediabuttons(play,fwd,prev) are not working with CorePlayer and HTCmediaplayer, only with Windows Mediaplayer are all features of the BT3030 available.

AD2P Audio

Any of you using the Desire HD with a BT Stereo Radio and/or stereo headset. The sound quality sounds really bad to me. I had the same thing on my HD2 @ default settings, but fixed that by changing the linespeed in registry. (bitpool on older WM phones)
Have been googling and can't find anything of the sort for Android. Is there a way to fix the audio quality?
My brother has the SE Xperia X10 and it has way better AD2P audio quality, even though it's still android 1.6. So it's not an Android bug, but rather a driver/setting somewhere.
Also the range the BT has is really small, I have a Logitech Pure-Fi Mobile speaker, which connects through BT AD2P, the quality is lower then on my HD2 (after tweaking) and the range is only 5-7m, while the HD2 managed to have skipless playback and higher quality at over 15-20m...
Apart from this I'm really loving the phone . And my car radio has full support for the other BT features. Like skipping tracks (in Spotify) and dialing numbers via the address book on my car radio instead of on my phone. And see who's calling on my radio's display.

Hi there, I'm really interested in that too. Would you say it's just a slight problem of the sound quality or is it merely unusable?
If you use Bluetooth headset you can forgive about good music quality. that's all
if you need good quality audio in bluetooth, buy this:

You can compare the quality with 96Kbps MP3 which is really bad imho, but still usable. It's about the same on many phones though, allmost all are set to max 31 bitpool... But with windows mobile it was an easy fix.
As the source code is out, I hope the ROM builders can soon find a way to fix this.
Hi
I use a pair of plantronics 590e headphones over A2DP and the quality is brilliant! I have not changed a thing in the setup.
I wont play anything lower than 192kbs (most of my mp3 are 320kps) as i am a real fussy git when i comes to audio.
I have used the standard music player and tunewiki and both are perfect!
Are you atchaly using the A2DP or standard mic and mono sound protcal for calls?

My MM200 Sennheiser work flawless. Music is rich and crisp!
You won't know the difference if you haven't heard the difference between bitpool 31 and bitpool 58, it's like night and day to me. Even 256kbps MP3 sounds bad to me tho.
Tried different audio files and it's not spotify causing it. As my brother is also plaything through spotify at HQ settings (which is 160Kbps OGG, comparable with 320+ Kbps MP3) ...
Eagerly waiting for an AD2P fix for android.
When I have my HD playing music through my Car's Bluetooth the quality is also pretty poor.
For some reason I can't choose any of the EQ settings? If I could just try and add some treble I think I could put up with it!
Just tried playing music via bluetooth to my sony head unit in the car and it became so choppy it was painful to even try to listen to it.
Great phone but really disappointed that there is a problem like this as one of the main uses of my phone is for audio in the car.
I use a Sony Ericsson mw600 and the quality is not good. The same headset with my sisters itouch and it sounds great. Is this a hardware or a software issue?
Sent from my Desire HD using Tapatalk
You must be careful with the mw600 that it connects in the correct mode. As headphones NOT headset for music. If you get it wrong it will sound awful. You can check by tapping the Mic during playback, if you can hear it through the headphones you have it set up wrong

i had exact earphone, but it's just awful. first of all; htc doesn't make me choose any sound enhancements, other thing is, my 320kbps musics aren't different from 96 at all.
ps. i am an audiophile.
Imanaged to find my old iTech BlueBand headset yesterday and gave that a go. Sound quality was loud and clear and well balanced.
Shame about the delay though - it's worse than I'm used to. Video is pointless as the lag on the audio is far too much to be bearable.

Bluetooth problem

I have this problem too. I looked up this issue and found that it is a music file compression issue. This is not specific zenfone MP1, but could the case for any budget smartphones. i still haven't found a 100% solution to this, but I have rooted the phone, installed Viper4android and enabled FET compressor. It helps.
If anyone here on XDA can help with the issue, it will be much appreciated.
Agree happens with my innova crysta when I connect via Bluetooth and this issue is also found when I cast to my android TV.
