Hello! I would like to ask, is that possible (at least theoretically) to get working steaming audio to wireless and wired headphones simultaneously [Android 4]? It doesn't matter, if you steam the whole system sound or just sound of single program (for example music player). The idea is to get audio output on 2 devices at the same time. If that is not possible, can anyone confirm possibility to steam audio using A2DP to 2 separate headsets? I've met some old devices (for example samsung cell phones on their own OS) which allowed to select multiple bluetooth devices as clients and steam music from the player simultaneously to multiple headsets. Thanks for your opinion and interest!
No chances to get this working?
Still no solution for this?
Currently I am on 7.0 Nougat but it was available on 6.x.x too. When sound through speakers is at very low volume, i.e. first or second setting and with Dolby Atmos on (on most players or apps supporting it), I can hear this hissing sound especially on speech (movies) or let's say at the start of a song when there is a single sound only rather than a background/mixture of it. It is bound to the sound playing and is not just permanent noise coming from the speakers or headphones.
Before 7.0 I heard this "hissing" via the speakers only, now it's to be heard also via headphones so I believe it to be software related rather than hardware. When Dolby Atmos is off, the hissing/clicking-like sometimes noise is gone. Probably it still exists but is barely audible at all.
Anyone else having similar observations? I'm not a DTS/surround sound specialist but wonder if the issue relates to how different channels/frequencies are set to work coming from the phone's (two only) stereo speakers/headphones or has something to do with the included amplifiers. I mostly use the custom DA profiles where sliders are above 50%. If pretty down or with some of the extra settings off (normalizer etc), the effect is less audible but still exists. Once I get the volume up via the phone's hardware buttons, "hissing" kind of disappears but this is more to do with the mixture of sounds where speech/isolated single sounds are no longer audible alone.
For the above reason I've been avoiding having Dolby Atmos on in almost any movie, Kodi or even games, still I love it for the way it changes the entire spacial environment, so if I knew what's causing it I'd gladly go for a fix. My Axon is A2017G.
Hello,
An update of the music player i am using (AIMP for android, free) just release an update (v 2.60) with the ability to choose between opensl and audiotrack for the sound engine. In audiotrack, i'm pretty sure it is driving the akm dac 4490 inside my axon 7 (mine 2017G B06) : when i switch between super and normal in audio settings there's a blank and i hear clearly the difference.
I ve search for other players that can drive the axon 7 dac and i found :
- stock player
- neutron
- google play music
is it right ?
Have a good day.

Hi, neutron player false positive I think.
Switching super HiFi and changing sound in player does not mean that it fully utilitize akm DAC. You will get better Sound on YouTube on any stream.
I will check aimp new features, thank you for the tip.
Try n7 player is my suggestion.
Use this if your bootloader is unlocked and the whole system can use the AKM DAC. Works on system or Magisk. https://forum.xda-developers.com/apps/magisk/module-universal-deepbuffer-remover-t3577067/page11

Excuse me, but can you explain why this enables the akm dac on any music player?
I don't quite understand.
Can you post a screenshot showing it works with your preferred player for example?

I've been using it on custom ROMs and my assumption is that it basically wires everything to the AKM DAC. That's because a) even in Youtube, Netflix and games the sound was clearly from the AKM DAC, and b) I'm on stock, was using Youtube without the patch and eventually felt so let down by the crappy shoebox sound that I downloaded it and flashed it.
Try it for yourself: download the flashable zip, put some music on YouTube (on stock it can't use the AKM DAC even by toggling the switch, that's why you should use youtube), then flash the zip and try again after it boots. There's no way around it, it's not placebo. It might sound worse for you if you have different cans or you want a different sound though

It allows the system sound effects like equaliser to affect all audio like how it was in KitKat. It's an option in ARISE and maybe default in Ainur (I forget, needs testing). This is just the function alone, it works well with the mod author's other audio FX installs.
I love Viper for tuning headphones for their individual Frequency Response with it's excellent graphic equaliser in V4A 2.3.4.0. Lowering output gain with it's advanced options seems to help lower Google Play Music so I can hear my game sounds higher, need to test this more to confirm. I find combining it's Speaker Optimisation with Dolby's surround with flat EQ produces the best speaker audio. Having tried most audio mods and effects on my old Z3C, keeping things simple with just these produces the best results. I'm yet to test a couple of mods that were incompatible with the Z3C and retest others on the Ax7. But as an audio purist and from experience, I don't believe any audio effects will improve audio rather than just modify the sound, unless they prove to retune the chip processing at a low level.
As Username suggested, have something like YouTube playing in the background and toggle the Hi-Fi to confirm a difference. It can be uninstalled by reflashing for system-based, or respectively via Magisk Manager, but TWRP backup in case. Audio isn't really something you can screenshot haha, it has to be on your device locally to be heard. This mod should be common knowledge by now for getting the most and expected out of an audio beast such as the Axon7 on stock.

Thanks guys.
And what about PowerAmp on a stock rom?
Still seems troublesome on 704 alpha. Mine seemed ok but then started getting a fail error for hi res.
I just use Jet Audio as my default player with 32 bit enabled and AM3D plugin used. Sounds great.
By the way I discovered a conflict scenario when using the deep_buffer remover to allow the AKM DAC globally.
Whenever a non equaliser effect supported app (not GPlay Music or Neutron) plays any audio simultaneously over the top of another app's audio playing. The hi-fi toggle will no longer switch until audio is paused. This isn't typically a problem as Super mode is preferred and will continue to function when on headphones.
However it means if an audio track is playing on speakers and any non EQ supported app plays any audio causing the conflict, then plugging in headphones they'll be stuck on the Snapdragon DAC. The reason being that speakers use the Snapd DAC and plugging in without audio stopped continues the locked conflict where hi-fi won't switch to the set preference.
A simple workaround is to just pause/stop all audio and the hi-fi preference precedence will automatically function on resume. This can be done before or after plugging, it doesn't matter. To confirm this the hi-fi switch will then function immediately when changed.
This took me several reboots and testing various audio to pin the cause. The easiest way to tell the difference between the DACs is to turn up volume to a level that feels comfortably loud on Super, then whenever the SnapD DAC is in use instead the volume is noticeably not loud.
I haven't tested if a notification or ringer sound will cause the same conflict issue. Safer to just pause/stop all audio when starting headphone use in case of any previous audio having already caused the conflict.

Hey guys,
I have recently switched from Oneplus 6 to Mate 20 Pro and the only feature I am missing so far is the lack of option to switch media output between devices (e.g.: from bluetooth headphones to speaker for example, without turning off bluetooth).
Is there any way this can be done? I have tried also with 3rd party apps such as Lesser AudioSwitch but I couldn't make it work...
Thanks!
I was wondering if there's any quick switch way to stop playing audio through Bluetooth and start playing it through the device speakers.
It often happens that I leave my car and audio will still be pumping out through Bluetooth instead of switching automatically to the speakers. I used to be able to switch this very quickly on my Galaxy S8 but I'm not sure if there's any way to do it here.
