Strange volume behaviour based on choosen language.

Today I switched from German to U.S. English inside "Language & input" and while staying at U.S. English the volume while listening to Spotify or for example Shuttle+ (music player app) is far higher compared to when using German language.
I need to restart the music app after changing language, changing the language on the fly while listening to music has no effect and it only works when using headphones.
I allways found the Mi A2 lite too low on volume when using headphones, but now it's far too loud at max.
Edit: I did some tests with different EU and non-EU languages and everytime I'm using an EU language my volume gets lower. Could anyone please double check it? Thanks.

Could someone please verify the above? Thanks in advance.

I did it and obviously there is a huge difference
Don't know why,but I think all problems will be solved with android pie

Thanks for testing. I hope it will get fixed with Pie, but I'm afraid Xiaomi turned down the volume for E.U. language users because of some stupid E.U. laws regarding maximum volume levels.

I don't think so, but this version now has many bugs like white balance, radio fm,double tap to wake,charging sounds... And I expect that these will be taken in consideration with the update

While there's life, there's hope.

Yes, true

Weird. It's the same here when using Spotify. Changed from Swedish to U.S English language. The volume out is way to low on the A2 Lite compared to my old Oneplus 3. Especially when pairing it with a BT-device such as my car or portable speaker. Also, there is a kind of "dampening" to the sound happening when using the equializer in the Spotify app. It starts at a high volume level and then drops, which in turn lowers the sound output even more. It's noticable when changing the prefered language- but improved over the Swedish language settings.
Can anyone else confirm low sound output while using Bluetooth? And using the EQ in Spotify, which in turn "dampens" the sound, both with wired headphones and paired to BT-devices.

While using my bluetooth speaker or receiver I don't see any changes in volume levels when switching languages and no "dampen" effect, but I know this effect from my cable-headphones. Sometimes even short passages of a song with probably a higher peak level get dampened but only when using an E.U. languge. But I've to admit I tested with Viper4Android and not the default equalizer.

I found (sort of) a fix for the issues I've been having with the audio levels being to low. Downloaded Equalizer FX (Pro) from Google Play. Increasing the "Loudness enhancer" in the Effects-tab seems to have done the trick. Audio still varies very briefly when you start to play a song, but it's no longer dampened or muffled. The downloaded equalizer does interfere with the built in one, a notification shows up in which you can choose to deactivate the built in one though.
Using my prefered language and location (Sweden) works with this method too. A little bit annoying that the soundlevel varies at first, but at least audio out now has some more punch. Will test it in my car with the bluetooth hooked up too; hoping it works there as well.

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?

Low Volume Bluetooth Wireless Earbuds Problem

Hello there fellow Xiaomi users, I have a problem with my Bluetooth earbuds and it's driving me insane! I hope you can help me out. When I connected my newly purchased bluetooth sony earbuds (the model is WF-XB700) I noticed that the volume was really low, maybe 50% less than it should've been. I was perplexed, but had a couple of quick ways to determine the problem. I connected the earplugs to a Iphone 8 and they worked just fine, 100% of their capacity. Then I connected my Xiaomi Mi 2A lite to some other bluetooth headphones (model Pioneer se-ms7bt) and they also worked as they should've. Then I connected the earbuds to a Xiaomi Mi A3 and to my surprise, I could also detect the Low Volume Issue there too! So, it must be something Android/Xiaomi related.
Then I went on a really energy draining odyssey on google to find a solution. What I did find was, firsty, that it was a known issue and secondly, that the myriad of solutions presented did not help me at all. This is a list of the things I tried, some of which spawned problems too :
1) Disabling absolute volume in developer settings.
2) Tinkering with all the options in the develper option - even the following (I will copy paste in from an other thread , which according to many people has worked :
Enable Developer Options (options -> system -> about phone -> click build number 7 times)
Press back
Go to settings, and search AVRCP.
Click on Bluetooth AVRCP Version and ensure it is on 1.6.
Next, search for Absolute
Select Disable Absolute Volume and turn this toggle on, if it isn't already.
Unpair all Bluetooth devices. Restart your device. Pair the devices again. To the right of each Paired Bluetooth device in the Bluetooth settings page is a gear icon, go into each device and turn off the Phone Calls toggle, leaving only Media audio enabled.
Exit settings, connect to the Bluetooth device, start playing something. Increase the volume using the volume up button and rejoice as the volume goes as loud as you need!!!
3) Putting the volume up in the Sony Headphones app. - So, officially the app doesn't support the WF-XB700. There are two options for detection. The first is a list of the supported devices (mine is not there) and the other is a ,,detect via bluetooth''. Tried the second option but it doesn't work
4) Increasing the volume on the physical buttons on the device. Mine are earbuds and have only one button for on/off
5) Ensuring the eartips are tightly fit in my ear.
6) Making sure the earbud isn't blocked by anything.
7) Resetting the phone
8) Changing the Region - This I actually did not succeed in doing. It turns out that the option to change the region has been removed. If there is a way to do it, please inform me.
9) Trying all the volume booster apps in the store.
10) Restart or enable and disable airplane mode
11) Forgeting and pairing the device again
Could the bluetooth version difference be the problem. Mine is 4.2 and the buds are 5.0. According to google there should't be a difference regarding the sound volume/quality, only range and connection strenght. Please help me, I have wasted more than five hours already and I ran out of options to try. Thanks in advance !

Xiaomi removes Bluetooth codecs intentionally from this phone (and seems like from Mi A3 too). Because Xiaomi dont want to pay 1$ fee for codec. Thats why it works as expected on iPhone. It's all about greediness.
Same codec issue is proper on Miui roms too. This means Redmi 6 Pro has an Bluetooth codec issue too. We can probably say same thing (according to ur first post) for Mi A3 and for its Miui version Xiaomi Mi CC9e.
- Redmi 6 Pro
- Xiaomi Mi A2 Lite
- Xiaomi Mi A3
- Xiaomi Mi CC9e
All of them probably has same issue. I didnt use any flagship of Xiaomi or any other Android phone since Jelly Bean so cant say anything about other brands except Apple. I used an iPhone between those times. iPhones has proper bluetooth codecs. You cant fix it via resetting ur phone or something like that.
SBC is the default codec and none of others will work.
Qualcomm is the owner of these aptX, aptX LL, aptX HD, aptX Adaptive audio codecs. We have an qualcomm chipset on our phone too but xiaomi didnt want to pay for these to earn more money from us. So thats why we are stuck on SBC. Dont buy any android device just by looking its specs from websites. Check out everything in the shop (bluetooth, camera,..etc.) before buy.

Sound Problems with Huawei Freebuds Pro

Greetings everybody!
Recently my older Melomania 1 Bluetooth In-Ears got damaged while working (left one) and I bought a pair of Huawei Freebuds Pro because of the very positive feedback online.
Now I ran into a problem. While listening to DnB or german stuff (257ers ) there is no problem at all (or I don´t recognize the problem due to the lack of drum-set) BUT when I get into real stuff like metal and rock, I notice a very uncomfortable noise when the crash of the drum-set is played. I don´t run into this problem with my Xiaomi Redmi 9A, so the Freebuds are ok. Farther my Melomania 1 didn´t run into this problem either. Unfortunately I am not able to explain the noise exactly...sounds like the random sound an old TV makes, but much higher pitched.
Settings are all on Standard in the dev options. I played around a bit, but it didn´t get better. A full reset did´nt work either. I disabled the dts-option while plugging in a wired in-ear...nothing
Hope you can help, thanks
Edit: Nubia RM5G Stock Global 7.15

facing same issue, did you got any solution ??

Oneplus 7t open beta 4 Bluetooth audio issues.

So I'm not sure if this is open beta 4 issue or anything like that, but I've recently started using Bluetooth headset and Bluetooth streaming in my car.
The audio quality is terrible, so I started poking around, downloaded equalizer app as EU version doesn't have it in the system, so I managed to improve it a bit.
Then started checking developer options and no matter which of the devices I connected to had HD audio greyed out and only SBC was available and quality wise all other settings there only had lowest values avaliable.
I know what you're probably going to say, that my devices don't support those, but they do.
First test I did was car bluetooth streaming, I borrowed my brothers poco f1 which sounded way better, but I didn't check the settings.
Now I grabbed my old Nokia 8 and started going into the settings and all the options were available when each of the devices were connected to it and sound quality was way better.
So this is not a matter of end devices not supporting the codec, but my OP 7t not allowing it.
Is there any fix or workaround for this issue?
I did try disabling developer options and re-enable them to enable HD audio, but it made no difference and if phone was restarted and reconnected to any device, it was back to off.
