I would appreciate feedback on DACs without using UAPP since the app brings its own driver interface to communicate with DACs. Outside the app DACs quickly loose the ability to work with various phones.

So if you have a DAC and a OPO phone, please give feedback without using UAPP and see if it works with a standard music player. Thanks!

My Yulong U100 works, but it is not a portable or widely available DAC.
[ONE Accessories] sandels:
I haven't used or installed UAPP at all. Apps I've used are Apollo, Soundcloud, Youtube, Chrome, and various games. System sounds and the like are all fine as well. As far as I'm can tell the E17 + OPO works with anything and everything.
[ONE Accessories] Reignogleph MMXI:
1. Then again, perhaps other people might like to know which DACs work with the OPO in whatever capacity -- with UARP or without. Anyone who's gracious enough to test their DAC with their setup and report their findings here has my gratitude whether or not they have to use UARP -- yourself included. (I believe the Dragonfly does require UARP, hence chazman's specific feedback, if I understood him correctly.)

No need to limit the scope of this thread to the setup you desire. Your interests will still be covered.

2. It sounds as though your Yulong U100 works without UARP, since you didn't mention using it and are interested specifically in avoiding it, correct?
[ONE Accessories] mrruin:
Generally from what I have seen almost any DAC with standard USB interface will work with UAPP. They really did a good job with that app and its driver interface, no doubt. But it is also no native support, there is an interface layer in between.

What would be perfect is that everyone who tries to use their DAC with their phone not only tries UAPP but also "normal" operation. Too often that information is missing. However if a DAC works without UAPP it will work with Ultimate Audio Player Pro as well.

So in my case the U100 works systemwide, with any audio/video app I tried. Stock and CM based roms.

perfect, thanks
[ONE Accessories] Reignogleph MMXI:
It isn't always true that any USB DAC will work with UARP. The success is very much dependent on the player and the DAC. Another factor is power, of course. If, for example, a USB DAC intended to be powered by the computer for which it was designed (cf. the Dragonfly) only worked with the OPO when an external powered hub was added, I'd want to know that as well.

Just did a search for "Ultimate Audio Player Pro" on the playstore and found nothing. Are you certain you don't mean USB Audio Recorder Pro?

Also: When people say that a DAC works with USB Audio Recorder Pro, I believe they're trying to say that it doesn't work without UARP. The convenient shorthand for them might be to add the word only:

"Schiit-on-a-Wheel Audio's Nordic Conquest DAC works with CM OS and the stock music app, but Megathrum's MeagerDAC works only with UARP and revision 340.2(c) of the ThermalCup ROM."
[ONE Accessories] mrruin:
that's the one

https://play.google.com/store/apps/details?id=com.extreamsd.usbaudioplayerpro

it is "USB" not "Ultimate" Audio Player Pro. Same developer.
[ONE Accessories] chazman1117:
I am listening to the V-Moda Vamp Verza right now using Poweramp. Works flawlessly, sounds awesome. Also works with Google Play music as well as USB Audio Player Pro.
[ONE Accessories] Reignogleph MMXI:
Got it: You meant to type USB but typed Ultimate -- perhaps because it turns out you're not alone.

I point this out not to be a vast hulking dink but because (1) there's an app called "Ultimate Audio Player," which people might mistakenly download instead, and (2) I googled the name "Ultimate Audio Recorder Pro" and found threads like this one, in which Head-fi members used the incorrect name for the app -- and one of them happens to be NZtechfreak -- a dedicated cataloger of USB DACs.

Note, too, that user phi303 had the same experience I did: S/he looked for Ultimate Audio Player Pro on the Playstore and found nothing. It's interesting that that's happened more than twice.

For the above reasons, I think it's worthwhile for people to know we're talking about USB Audio Player Pro sans the word Ultimate. Since I wasn't familiar with that UARP offshoot until you made me aware of it, I wouldn't expect every DAC user to know it either -- not automatically, at least.

Both UARP and UAPP use drivers that bypass the limitations of source software, which is why I suspected they had to be the same software with an incorrect initialism or variants of the same original software.

Update--

After extensive listening I had to return the V-Moda Vamp Versa DAC. When using the settings required by the DAC for an android phone there is audible (barely) noise. If you change the settings to apple mode - the noise goes away, but the battery drains extremely quick. No Bueno.

Another DAC

One works with

MUSE Audio X5 Mini Hifi USB DAC PCM2704 Sound Card Board

I cannot post link, but you can search for it on ebay.

This is jsut a $10 DAC and headphone amp. The sound quality is actually very good. Noticeable improvement compared to the headphone jack. A friend of mine does not like the low, thinking it is too harsh. But to my ears, it is just perfect.

The DAC does not have a volume control, and it is very LOUD! Be careful not to hurt your ears - you have been warned! I had to buy a volume control, which is more expensive than the DAC...
[ONE Accessories] gsmyth:
Which USB cable do you hook it up with?
[ONE Accessories] qing319:
The DAC comes with a USB-A to USB-B cable. So the connection is:

OPO -> micro USB to USB-A female OTG -> USB-A to USB-B (comes with DAC) -> DAC -> volume control cable -> headphone
[ONE Accessories] gsmyth:
Is the sound quality improved when listening through headphones? I'd be interested in this as its so cheap, I'd be looking to use with headphones, they're nothing high end just sennheiser 205 HD.

What happens you turn the volume down on the phone, is it still high coming out of the DAC?
[ONE Accessories] qing319:
I think it is pretty good. i can tell my m50x and HD 558 sounds better. But sound preference is very personal. My friend did not like the low. He thought it is not as deep and tight as from computer. I listen to female vocal mostly, it serves me very well. Eva Cassidy's voice sounds clear with more details.

The bottom line is it is $10. Even if it does not work for you. How much are you going to lose? :)

if you phone already has a volume control, it should be OK as long as you don't set it to max.

Hope this helps!

OnePlus 3T with Fiio Q1 mark ii works really good

I used the app "DAC Fix for LG V10" this makes it possible to use your dac system wide, tested with: Deezer, Youtube, Quboz, Tidal, ... its your system sound sow you will also get notifications sounds etc.

I'm using the DAC: Fiio Q1 mark ii

With my OnePlus 3T (Android 8.0.0, OxygenOS 5.0.1)

Using a "USB Type-c to USB 3.1 converter" and the provided MicroUSB - USB-A cable.

Headphones: Sennheiser HD598 en HD598CS, the sound better then I ever heard and have a special soundcard in desktop, but this is better!

Good thing about this DAC is that it has it own battery so doesn't drain the battery.

Only make sure if you have the auto start of the "USB Audio Player PRO" disabled if you have that one installed, they will give conflicts, this app is still the best option if you want to play highres files like Flac, DSP, ...

Hope this helps some other peoples.
[8525, TyTN, MDA Vario II, JasJam General] tadzio:
I have a strange problem with my O2 Trion: in the Connectvity bubble that pops up when when I tap on the little GPRS icon in the title bar, I get no connections listed and also no "connect" button - just a text liek "Go to network settings and add a new connection to access Internet" (rough translation from the German text).

The funny thing is that I do have network connections defined in the settings. After a hard-reset, I allowed the O2 programs in the Extended ROM to install themselves, so I have the original O2 connection settings. And PIE also connects without a problem.

So, would anybody know what makes a connection become listed in that bubble, and how to get the "connect" button back?

Thanks in advance!

Daniel

PS: I compared some values in the registry of my Trion with those of my old Magician. I found that Microsoft moved the ConnMgr from HKLM\SOFTWARE\Microsoft to HKLM\Comm and added a few keys, but I could not find a difference explaining the symptoms of my problem. Maybe someone of you would be so nice and export the ConnMgr part from their registry and send it to me, so that I can compare them? I do not think they contain any sensitive information (passwords etc), but it never hurts to look before you send anything.
[8525, TyTN, MDA Vario II, JasJam General] tadzio:
Nice work-around!

Okay, it seems this is not just my device which has that problem, but rather a design decision by Microsoft.

However, I think I found a very nice work-around for the problem. I just added a short description to the Wiki, on the page http://wiki.xda-developers.com/index.php?pagename=Hermes_Utils under the heading "Easily connect/disconnect GPRS".

Cheers

[8525, TyTN, MDA Vario II, JasJam General] harryk1372:
:)

looks like you have already found a wrokaround for this but try this if you still want to see the connect/disconnect button and the time of connection in bubble. It also allows you to toggle between gprs always on and turn off gprs when the device is not used for the amount of time of your choice. very handy.:)

[8525, TyTN, MDA Vario II, JasJam General] tadzio:
Thanks for the hint, but I had installed this little program already. It does a lot of nice things, but didn't help with the missing connect button.

In the meantime I heard from a few O2 Trion owners that they actually do have a "connect" button, so it's not a problem with WM5 per se. Although I have a work-around, I would still like to understand what really goes on there.

Cheers

Daniel
[8525, TyTN, MDA Vario II, JasJam General] harryk1372:
hmmm... so you are right. i just confirmed it myself that it only enables the disconnect button but not the connect button when it's disconnected. i have gprs always on and did not realize it until now. it might be that i only saw the connect button when i was running an older version rom on my universal that did not come with gprs always on as the default. sorry for the confusion...:(
[8525, TyTN, MDA Vario II, JasJam General] Menneisyys:
Yes, it's a (in my opinion, rather questionable - in pre-WM5 OS'es, the ability to start (/stop) connections manually and, what is more, the ability of choosing between the Internet and Work right in the bubble was a great asset) design decision. It's only the "Disconnect" button that's hackable.

screen connection problem

hi buddy,

I have the same problem and i think it's a connection issue.

In my case the screen sometimes goes off or changes color intensity or inverse color.

the solution is to knock on the lower side of the screen and it turn on correctly.

firstable it happends rarely but with the time it's comming very annoying.

now just holding the phone hardly or connecting the headphones or charger the screen goes ****ing itself and i have to knock severly or push it to resuscitate it.

i'm thinking in opening the device and look the connections to solve it.
