I am currently using Cyanogen Domination but if you want to stream music via bluetooth beware. I don't use the car port but I am using bluetoth headphones and I have to unpair/pair every time I want to use them. There are other ROMs that don't have this problem LeeDroid and Bindroid for example. So my advice with any Cyanogen rom is to find if there are any bluetooth streaming issues

[Q] Further increasing the GN2's Audio Quality?

Hey guys,
I'm running Skynote 8.3 at the moment with the Perseus Kernel.
I primarily use Poweramp as my audio player of choice. On top of that, I use 320kbps MP3's and FLACs.
I've tweaked the DAC through STweaks to the best my ears can appreciate. The same goes for Poweramp.
Now, is there any other method of further increasing audio quality with these two running simultaneously? I'm looking to increase the dynamic range of my music a bit. I primarily use ATH-M50's or Super.Fi 5EB's.
I'm not quite looking for things like Ac!d audio, Beats, etc. I'd rather not have 50,000 audio processors running simultaneously either. Ac!d always messed up for me anyway..lol.
Any ideas? I'd like to install things that are easily removable rather than a slew of software included in a single package.
Thanks!

Install Sony's xload and clear sound audio enhancements
You can get the zip from pimp my ROM in the play store

XLoud I tried once, it was too loud lol.
I think I'll give the other enhancements a try though, thanks!

[Q] does paranoid android have usb audio out natively

im currently using cyanogenmod on a samsung galaxy s3 and where as it does supposrt usb audio out it is not native to the whole device. for example i cant use any music player and have it play via the usb, i have to use a custom specific player

Sounds like something you need to ask in your device thread since that's not an officially supported device.

[APK] USB Audio Player Pro, is a standout & uses our DAC to 192k!

USB Audio Player Pro.
Plays DSD, and FLAC files up to 192000 bit rate on our standard DAC, no USB Hw used.
FLACs get can be played through UAPP at their full glory from non OTG memory.
SACD rips are converted to PCM at 192K from OTG only, which forces you to pick files individuality. If played through UAPP they get downgraded to 44K.
I have tried out every notable player and none sounded like this. I have always preferred vinyl but when Super Audio CDs started growing, I was thrilled. Now I can play my hard drive stash on my phone! Too bad the app does not see OTG.
Playing from OTG is a bit convoluted ( more than a bit ? Depends if you have audiophile ears).
I use File Commander to get UAP to play/find the .dsf or .flac.
Then once playing you can create a playlist as you go. Never having to pick it again with FC.

It isn't easy messing with Mother Android!
File Commander is the only app I can find that does this service well enough. It can be slow on hard drives greater than 200 GB. It is not much good for housekeeping chores.
Update, there are others: File Manager + unlike FC, does a download (efing slow) , X-plore and B1 File too but do not recognize DSD. ES is useless for OTG. Filers are in a sad state for MM on our phone.
I use Solid (not classic) for deleting/ copying.
Note this app does not limit any low or high frequency junk. Vinyl transcriptions that I thought to be OK are not listenable due to pops and clicks.
Be sure to choose Android bit rate as Variable (pic 2).
See pic 1: using FC to load a .DSF (DSD) to UAPP from OTG drive. Pic 4 - 6 settings I used to get 192k.
Pic 7: .dsf (DSD) file residing on internal memory (or sdcard) showing 44k PCM.
Pic 8: the plugin EQ tweeked for my Apple earbuds.

How is the DAC capable of such? Does it even sound good for a mid range phone or even compared to a dedicated DAC?

As I compare the DSD (.dsf) output from a file residing on OTG (192 k PCM) vs the same from SDcard or internal memory (44k PCM) it is stunning as to stereo imaging and placement of instruments beyond the space in my head. Highs are much smoother as well.
I was considering buying a 40 dollar ESS DAC (micro usb) on Amazon and an adapter. Now ....

I think that ESS DAC would allow DSD direct!

Also at volume near 100% I notice no clipping of our Amplifier.

This is different when using only the phone and no DAC. Neutron may try to render at higher rates but it never blew me away. Nor is there any acknowledgment of it's output.
In UAPP, I did not have to check the Android output shown on the player screen. It was like night and day.

Uuap would not have sounded better if I had not checked the android bitrate to be variable.
Standard settings of it and, I think, other players result in 44k output through the phone without any DAC present

Will it work with music on the SD card too? Or does it have to be loaded from OTG?

It does work! My S7 is dead to me! This phone is great. My FiiO Q1 might collect dust.

I just made a request for support with a big name player that browses OTG and plays DSD too. Can you guess who?

So I am considering getting this app, however want to make sure it will do what I want it to, LOL.
So I dont have any external USB DAC right now, and normally stream music to my car using Bluetooth to my AudioEngine B1. It sounds good, but looking for the Android DAC to help improve once I start playing my local DSD files and high quality recordings. With this setup, will this improve the sound considerably?

You may want to wait as UAPP will not browse OTG and said to me, no plans to do it.
Yet PowerAmp does browse now and they say they are tring to support all phone DACs
Go my post in Q & A. Register and submit.
You may not get 192k over BT

You can play OTG from a Playlist, it is the only way to get 192k PCM from a dsf too.

I am still on Marshmallow and unrooted. Nougat users, does USB Audio player play high resolution?
Does File Commander browse OTG and pass audio files to the player?
Thanks

Any Nougat stock no root working equalizer software for MZP need advices what to use.

General Issues with USB Dongles and external USB DACs

There is another problem with the Pixel 6 (6 and 6 pro) devices. External USB DACs and dongles do not work properly. USB Host API or the DAC offloading and hand-over are bugged. Apps like Tidal, Neutron, USB audio Player Pro crash or can't play music in high res. The problem has already been reported by some users. There has been no statement from Google yet.
A work around for me to get music playing and stop apps freezing was switching off the toggle for "allow all apps use mic" in system/privacy settings.
But this does not solve the issue, as the apps still can not access the USB Dongles or external DACs directly and by pass android system limitations and software processing.
Google skips the 3.5 port and users are forced to use dongles, etc., which do not even work properly.

Google is going the Apple way by certifying hardware that is compatible with the P6P and P6. Their response will be to buy a certified DAC or wait for a software patch

Maybe they're still using some old Android API and need to start using a newer one. Hopefully, they update it for Android 12.

Try their website https://www.extreamsd.com/ or their support email address [email protected] and let them know. If they're not already actively working on a solution, hopefully they will after you talk to them. Good luck!

They are all aware. I've talked to Davy (USB audio Player Pro). They removed the app for pixel 6 and pixel 6 pro from playstore because of the mentioned issues. The problems have nothing to do with their app. E.g. neutron and tidal are also not working properly or freezing. Google needs to fix their USB DAC hand over.

Wow, that sucks. I hope they fix that pronto! Otherwise, I smell a class-action lawsuit (not from me).

Is it app specific and/or USB DAC specific? Because my FiiO BTR3K works fine.

Which app are you using?
Some apps can play music, but most can not bypass Android Software processing.
If you e.g. use tidal in MQA the app connects directly to the DAC and plays in high res.
Same does USB audio Player Pro. Then you see at the bottom "DAC" + bit...
Actually if I get it to play music at all, it's just direct mode, which means nothing.
Some dongles and DACs seem to be working, but just in low/software-processed quality.
So the problem is playing REAL high res, instead of android software compressed/processed audio.
Therefore the USB API seems to be broken. So as soon as the app tries to get direct access to the DAC it freezes or crashes.

Yeah, maybe you can play some processed, low quality music through your high res DAC. So the DAC is pretty useless, you could use a standard dongle with bull**** chip, as it doesn't matter.
I know a little bit what I'm talking about.
I did some audio ports and worked with UltraM8 and the other dudes on the Ainur Audio mods.

Yeah I don't even use it wired anyway. I just wanted a very good Bluetooth DAC. For me it's the best of both, using my wired headphones yet not tethered to the device it's connected to.

No issues playing the Hi-Res/Ultra HD music files on Amazon Music through the official Google dongle. Sounds pretty good, can't really tell the difference between it and the V60 that I've had prior.

As far as I know, Amazon app is still limited to phones native sampling rate and does not bypass Android limitations (android mixer). So it does not make use of the external DAC directly. Different story again. But please correct me, if I'm wrong.
But at least it's one DAC that plays some music.

Here the link to the Google support conversation.
What to do about USB-C audio outputs (adaptor + USB DAC) with pixel 6? - Google Pixel Community

I had a OnePlus 6 with Jack 3.5 and I bought a DAC for the Pixel 6 and I find this problem, I hope they will solve it soon. I can play music but with worse quality

I just read through the conversation and it just baffles me. So the "official" Pixel support forum is run by volunteers who basically tell you "if you have a problem, don't bother us, we just give you pre-prepared text-blocks - if they can't help you, we're out" - if you want "real" support, go and use "feedback form" - meaning you write a wall of text to an known person, won't get any sort of answer or input and have to pray that Google will care?
Uff.
I mean, as a Pixel user you can always try the
-> Settings
-> Tips & Support
-> Contact us
form, that way you can at least write to a person/talk to a human, even though they will most likely also just form a "feedback form" after your conversation, since they are powerless Tier I tech people.
I hope that Google can fix those problems here, so you guys can have fun with your device. Google certainly doesn't deserve the "our phone just works" - status, if they forget to add basic compatibility to common third party hardware.
