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?
Hello people,
i'll be getting an OP5T soon and even though OxygenOS has a favorable reputation i'll certainly end up flashing a custom ROM anyway. however, there's a nagging question, as hinted at in the title, that doesn't seem to have been addressed anywhere, or at least i couldn't find anything searching the forums and it's never mentioned in respective ROM threads. the OP5T running stock Oreo OOS supports both aptX HD and LDAC, if i'm not mistaken, but do custom ROMs generally support those codecs as well?
my current phone is a Z1 Compact running one of the last official CM nightlies released back then and those didn't support aptX, which the stock ROM did, afaik. i don't really have experience in Android customization but from what i've read in various threads, just unlocking the bootloader can inevitably trash various things like DRM keys and camera functionality. the advanced BT audio codecs are important to me, so i need to know what i can and can't do in order to preserve them.
any input on this?
I think any Android 8 based rom support these codecs
I have a Xperia z3c with carbon rom (Android 8.1) and it support these codecs

first things first, thanks for the input.
that does sound promising. i mean, if the codecs didn't work on a custom ROM no matter what, because BL unlocking erases/invalidates the libs or something, surely the dev would've removed them from the selection.
i've read about the matter with Oreo, its native support for all BT audio codecs (whatever that actually means) and Sony's LDAC donation to AOSP. though apparently there was some confusion, as all codecs appeared in the settings selection even though they didn't actually work due to lacking libraries. and while LDAC is part of AOSP and technically free to use by any OEM, it still requires a device certification from Sony.
so... there seems to be a difference between "supported" and "functional". you don't happen to have a pair of compatible BT headphones at hand for testing, do you? your Z3C should at least give you regular aptX, as that's what it shipped with, and perhaps LDAC

thanks for the screenshot, that was a nice confidence booster. i went ahead and flashed Zoe ROM, can confirm that both aptX HD and LDAC still work. so unlocking the bootloader doesn't touch the libraries, which i guess are located in a partition that you don't usually wipe, and every ROM based on 8.0 or later should support the codec selection
Hey,
I'm currently looking for a smartphone with long battery life and support of HQ sound (LDAC preferred).
I found some ROMs with Android 8.0 and I heard that this version of OS supports LDAC. Does it mean that when I install one of these ROMs, I will be able to use LDAC?

LDAC is included in AOSP since Oreo so you should be able to use it on every 8+ ROM until someone will remove it from his ROM. It is visible in my codec selection menu on LOS15.1 but I can't test it for you since I'm not in possession of any wireless headphones. I believe that you should look for information and how it works on other phones threads too, not only here. There is possibility that Lineage doesn't support this codec itself since stock haven't supported it but I'm not sure about that since LDAC is part of AOSP unlike AptX for example where your phone needs to be certified to allow developers to include this codec in official builds.
Basically you can add any existing bluetooth audio codec to your phone's ROM. There's not any hardware requirements besides bluetooth so I believe that you should be able to use it.
Tested on the lousy zenfone 3 zoom (stock 3.5mm audio sucks inspite of DAC chip because of the poor engine optimization) and it worked like a champ but i believe other devices with SN 625 may benefit from it and they are A LOT, (use 709 build ONLY) other builds won't work as good, i tested them all.
Please do make a feedback on which other device this worked.
Snapdragon 845 devices (e.g. Sony XZ2) – improved Hi-Res Output detection
Sony XZ/XZ1 – improved Hi-Res Output detection
Lenovo X3 – reenabled 24bits
OnePlus (1st edition) – disabled DVC for Hi-Res output due to forced speaker playback
added new per-output option – No Duck – for cases when notification causes issues. Activated by default for Hi-Res output for some Snapdragon 625 devices (Asus Zenfone 3)
HTCs @ 7.0 – improved Hi-Res Output stability
Nexus 6P – fixed notification coloring
Enjoy Hi-Res music all.
Direct download, use poweramp unlocker to activate it.

Did you toggle the 'Wired headset/AUX" ? and was your test with headphones or via the loud speaker? and what your headphones are?
This release 709 worked for me gloriously! the only problem that it's not free and needs some work that you can find on youtube or i would post a fellow up about the odds of activating it but i just needed a conformation that it at least made a difference by utilizing the DAC chip on board!!

I've downloaded the apk you uploaded and followed the screenshots. It made zero difference to the sound quality. Poweramp DVC is great on other devices, but on my zenfone it sucks, the audio is distorted, the only way to tolerate the audio quality is by disabling it. Best player I could find so far for my zenfone is Phonograph.

The zenfone 3 zoom have an amazing sound quality and believe me the bass is insane via a good headphones, you just need to find a solution to make use of it's potentials, if you want to go throw troubleshooting provide some more information like the exact model and what software build you are currently running... you are right about the distortion i was very upset with the sound quality at the beginning but poweramp made the DAC work properly.

I wouldn't say that the sound quality on the zenfone 3 zoom is amazing. This DTS audio thing is terrible and makes sound awful. I've installed an even older version of poweramp and tried your solution, and it made a difference with my JBL T210 (not the best one around, surely). However, using Poweramp with DVC on an old Galaxy S6 that I have laying around is still miles better. Sound quality is my only complaint about this phone, that's why I was hoping for a custom rom for this thing.

Yeah you're absolutely right that DTS is a marketing thing and it sucks, you just keep trying on that poweramp 709 build only and try downloading it from APKPURE or somewhere else because the one that i provided was patched with lucky patcher and i hoped it would work with a non-rooted device to skip the activation process but apparently that is not the case, after i reflashed the phone and got rid of the root access i had to install poweramp unlocker and i have to reinstall the the main app every 2 days because without the root i can't seem to be able to activate it, keep digging, i know what a good DAC sounds like, it's not an HTC native level but it's miles ahead of the stock drivers and even better than viper4android module on magisk.

Ok, audio via phone Bluetooth connection question.
I recently exchanged my Samsung Galaxy S9 for a OnePlus 7T, and I notice that with the new phone, I have to play music on my car radio (Kia Forte) at a higher level of sound. Sound quality is good though. Has anyone had a similar experience, be it an Android or an iOS phone? Thanks!
I've been trying to work this out myself.
I moved from a Galaxy S8 to a OnePlus 7t and I stream my music via Bluetooth to my JBL Charge 4; I have been feeling like volume has been a lot lower and bass is just not there like it was on the S8. But then I had been flicking between Spotify and Deezer on my S8 so that could have contributed to the confusion as the volumes levels differ a bit on there too.
I'm on 10.0.9 (Stable - EU) and believe it to be quieter and lacking in comparison to Samsung :/
Try dolby atmos equalizer and you can feel the difference of volume boost and audio quality had same problem on my car with sony BT stereo but with that app it's a lot better, give it a try.. You can find it under "oneplus 7t themes apps and mods"

My T-Mobile 7T has the Dolby Atmos equalizer option, and it does help with sound quality, but not overall loudness.
Also, I tried this on my OP, and it more or less helps with a bit louder sound, but not as loud as the Samsung.

Yes the apk.. to get it working properly you need to disable the in-built one, either via adb or disable application app (root)
