Anyone tried A2DP on p3300 ? It works ? Someone can suggest me some model that works on it ? I need to know for a xmas present. Thx in advance.

I have SonyEricsson HBH-DS970 working well. Also applied the ÜseJointStereo"= 1 tweak to enhance the stereo separation effect

Do you still need to apply a registry tweak to enable stereo over bluetooth.
Hi there,
I've tried searching, but to no avail... Hope this is the right forum.
Is anyone implementing / attempting to implement the Samsung Professional Audio SDK with the N7100?
My thoughts are around the latency-free audio and being able to use the new Amplitude iRig for android for Guitar FX.
Cheers,
S.

--edit my bad, didn't read your thread carefully
Guys,
Can someone explain to me how I can use and enable Viper4android to work with my (USB Dac) Fiio e17k connected to my OP3. I mean I always used Viper4android and recently I purchased the Fiio e17k Dac/amp, it works on my OP3 through the USB-type C to micro USB in to the Fiio E17k, However Viper4android is not working. Strangely enought it works when I plug my headset directly to my OP3.
Its frustrating, and I really that it could work out for me with your help.
Current ROM- Resurrection Remix 7.1.2
That's normal. Audio software modifies the sound produced by sound ship (DAC in other words). Using external DAC means you bypass your integrated audio chip completely so you also bypass your sound mods. The device has nothing to do with external DAC, it uses its own software.

In this post it tels that it can work but I dont understand how they do it step by step ( https://www.reddit.com/r/headphones/comments/74ndqf/android_with_usb_dac_and_u_viper4android/ ). Also when you open Viper4Android there is an option for usbdock, it should work but I think we need someone who can help us step by step to perform a workaround because its not really simple for everyone.

i have a Fiio Q1 DAC too and that doesn't work with V4A since i updated to Nougat and above
Earlier it used to work fine when i was using Marshmallow.
Hence, i believe Android 7 & above have some limitations with respect to audio mods

hmm intersting, so you believe that android below version nougut should make usb dac work on viper4android ? if so on what roms did it work for you ?

Not a big fan of custom roms hence i had used it on my Oneplus One running Cyanogenmod and Oneplus 3 running OOS
I think it has something to do with the sampling or bitrate of the DAC. I have an Essential PH-1 and the included USB-to-headphone adapter (has tiny DAC chip in it) works with V4A as headset, but my Fiio Q1 gen1 does not. The easiest workaround would be using analog input instead of digital, unless someone knows how to force output sampling/bitrates?
Edit - found the answer here https://amp-reddit-com.cdn.ampproje...r4android/?amp_js_v=0.1&usqp=mq331AQECAEoAQ==
That guy explains that V4A can't handle output above 48KHz
I've researched on the web for quite some time on this topic but didn't find anything definitive yet (a clear answer if it works - how to set up, etc.):
some are mentioning that only the right app would be needed to be used (well, no)
a few are mentioning that there is supposed to be an app that toggles between default dac (wcd934x) and quad dac (es9218p)
others are referring to a setting in build.prop (nope, the ROM doesn't have the mechanisms to react to that - and neither do the drivers most likely - or at least we need to make sure that this stuff is included for us)
then there are a few mentioned cases that there's support on lineageOS on board to utilize the es9218*
there's also occurences where it's mentioned that the sound stops working entirely when switching tracks (?!) - so it's still WIP
so at least the kernel needs to be set up that way - but there's probably more to it

edit:
For those who only use the quad dac for local playback (music stored on their device; NO Youtube, Streaming, etc. with Quad DAC on LineageOS/AEX/RR for now) - there is an app (for purchase) that activates & uses the quad dac (es9218p)
I've tested it and got the same specific quirk / behavior I got on LG Stock ROM with activated quad dac option.
The app is not cheap (6.99 EUR, >8 USD) - but it's totally worth it, the UI is great, the sound output is awesome (finally quad dac on non-stock !) and it uses a "custom developed USB audio driver"
extreamsd said:
This bypasses the Android audio system completely, meaning that Android's limitations regarding bit resolution and sample rate (16-bit/48kHz) are made irrelevant and high quality audio streams are fed directly to the DAC, making playback up to 32-bit at 384kHz possible (depending on the DAC capabilities) or even DSD.

Well, it's not fully "solved" - since only locally played content (no videos ! no streaming !),
but at least local content is played through the quad dac (es9218p).
So thank you very much for that hint (and everyone else who kept on mentioning it)
And: YES, the quad dac definitely is being used with USB Audio Player PRO
First I thought that the more punchy sound output could be placebo/imagination (with Xiaomi Piston V2 & the B & O Play Headphones),
but then I plugged in the Xiami Hybrid Pro (these are the only headphones that don't work with the quad dac for me - since they cause a extreme loud hissing/static on the left channel),
and after a few seconds I got the characteristic hissing on the left channel - that means that the es9218p DAC/sound card/AMP is definitely being used
That's the same behavior I got on LG Stock ROM after enabling the quad dac

In theory we would just need to write a HAL or something like that, which interacts with the kernel driver, its already there, just something needs to talk to it.
And some Overlay in the Settings to enable/disable the HAL.
The HAL would be C/++ while the Settings overlay would then be Java .... I could do the later.

I don't really have the programming skills to do either, but I'll buy you guys a beer if you figure it out. That and the vibration motor issues are the only reason I'm still on a stock ROM.

Vibration motor issues may be solved. Dev is currently trying user @Krakophyst suggestion to replace vibration motor files with those from V35. Now why that would work better than actual V30 files, don't know. But it worked for the user.

The vibration problem came up, but I think I fixed it by replacing vibration related files in /vendor and its subfolders with LG V35's files and it has been working fine for about three days now.

It works, because the V35 files have to work on AOSP (because of treble implementation on the V35), while ours depend heavily on the LG framework (which probably does its own stuff to the vibration services), and arent supposed to ever run on AOSP.

Aha. Then score one for Treble on an LG phone that has some similar features to ours. V35 may never get bootloader unlock and root, but we can cannibalize it for the V30.

IF (a big if) volte works on GSIs (which nobody tried so far from what i know, i only know 1 person with a G7, and he cant use VoLTE, thanks to the carrier), those files are highly device specific (or atleast SoC specific), its very unlikely that those would work for us.
I could try, but dont get your hopes up on that.

I grabbed the app, it had some Network options (notably for Tidal and Google Play Music) I would assume using those options from within the app would use the DAC? Can't test personally as I'm currently using Spotify but would happily switch if I could use the DAC on a streaming service, assuming at least ~80% songs I have on Spotify are available there.

Could very well be that it provides or uses hooks to interact with those and I guess it should work (if it works, if it doesn't you can nag the devs to fix it - it's a somewhat "premium" priced app after all, and support is to be expected )
I'm not using any streaming services, sorry - so can't test.
Pretty sure there must be users of Spotify here around so maybe those can give some feedback
Edit: mistyped
Anyways I started a Tidal subscription (hifi student plan). From listening to a couple songs things definitely seem clearer but can't say for sure if it's using the DAC or placebo/better quality audio is the cause.

I probably will be switching off Spotify in favor of this; only because the student plan for it exists and I do hear an audible difference with their hifi settings ($19.99/month for hifi plan without a student discount yeeesh).
even using this app on non stock rom can we still get the same high volume output from the stock rom with HIM sound mod?

just tried it with the Xiaomi Pro HD Hybrid and I get the characteristic strong hissing noise in one of the channels (left channel) - that's the only headphones I get that weird thing with when the quad dac is activated (on stock ROM).
This confirms that the es9218p ("quad dac") also works with Onkyo HF Player on non-Stock :good:
So obviously these applications HF player and USB audio pro player have some line of code that is triggering the quad DAC to be utilized. Correct?

Would you still need to use higher ohm headphones to enable the quad DAC , or will this (USB Player Pro) allow any headphones to work with it?
I've got 4 sets of IEMs that I love, and would hate to have to start all over again buying new ones.

Nope, I'm using the quad/dedicated DAC with "normal", low ohm/impedance headphones myself,
the only "difference" is that there isn't much noticeable difference compared to the default (qualcomm) audio DAC
So you'll be fine,
you can choose to get yourself higher ohm headphones in the future (after careful evaluation, of course) take your time to choose the ones that best fit your hearing preferences (sound response, etc.)
Any updates on getting the dac to work with non stock roms?
Hi everyone, I´m about to buy a new pair of earphones and was wondering if our phone is compatible with a better audio codec
thanks in advance
samsung a50 doesn't have aptx codec, it only have A2DP the default for streaming audio over Bluetooth. but if you buy aptx earphone it can be use with a50 though
There is aptx option in the developer settings!
