The U11 Audio Thread, Standard adapter and third part USB Amp/DAC - HTC U11 Guides, News, & Discussion

This thread is to discuss the audio quality on the HTC U11 with the standard 3.5mm adapter or in use with a third party Amp/DAC.
Please post your findings and solutions with the gear you have used and Apps.

Okay did some extensive testing and research on third party Amp/dac with several devices.
All has to do with Android and their generic USB host audio drivers. As mentioned in a lot of headfi threads.
Apps like Deezer and Spotify or "normal" music players will use those Generic Android USB host audio drivers. Also with external third party dac.
In the Neutron Audio player you can see which driver it will use when sending out Audio. On the LG G4 3.5mm output its (audiotrack) JNI and also on the U11 with the HTC adapter.
On the G4 with Neutron it has the sound signature as with normal players with 3.5mm output.
On the U11 playing with Neutron it has also the same sound signature when streaming with Deezer or Spotify.
In Neutron you can select Audio USB device, and in my case the Dragonfly Black. If you select this in the settings Audio Gain is much higher and headphones comes to live. So it benefits the Dragonfly DAC. Also you can see in the output screen its playing through Dragonfly. Bypassing the Generic Host Driver.
On Deezer/Spotify or other player you will slightly here some difference (with third party DAC )in sound quality but its barely noticable. Because Android uses the JNI Audio. And audio output volume is the same .
So conclussion: if you have music stored locally on your U11 and you play it through Neutron, Onkyo HF player or the great USB Audio Player.
Yes you will benefit from an external Third party DAC.
Otherwise you will barely not...
These are my findings with the U11 (without root) and Dragonfly. Maybe for the Fiio K1 its different but suppose not.

I'll share my findings here when I'll get my hifime sabre 9018 type C dac, should be here in two weeks.

I have the Dragonfly Black and thinking of getting the Fiio k1. I'm assuming I need a USB A to USB-C cable. I plan to mainly use my Sony MDR-7506s. They didn't sound bad using the included adapter, but I think I can get a little better sound.

Yes you will need a USB C OTG USB A adapter. And you are ready to go.
My advice first try out your Dragonfly. If you are satisfied with the sound.
Where do you want it for? Which apps?
I think Soundwise it's a downgrade from Dragonfly to Fiio. But hey if it supports Spotify or Deezer? Thats my main goal.

Would these settings also be in PowerAmp by any chance. Looking to buy the DragonFly, Anker USB-C3.1 to USB 3.0 A Cable and Ivanky Aux Cable. Or should I be using the Neutron Player?
Honestly the supplied DAC hooked to a no-name brand 3.5mm to 3.5mm cable to my jeep sounds great as is. Volume on phone set at maybe 75% and Jeep volume maybe 75% as well and it is pretty loud and clear, Bass is booming and good highs. If many of you say an external DAc will greatly improve the audio, im all in. Summer is around the corner and sitting in traffic everyday needs windows down music up high.

I have tested Poweramp but does also uses the normal USB Host Drivers.
You will have to switch to indeed Neutron Onkyo HF player or USB Audio Player. Which is the nicest IMO.
And yes if you will use those Apps with local music content (or Qobuz Tidal, Spotify and deezer are not supported in that app) its way better than standard adapter.

Ok sounds good, lol. Amazon says my goodies will be 115.00, not too bad for none bulky equipment.

So far I notice no difference between using the K1 on a high end PC and using it on my U11, as in I don't think the K1 cares which host driver is being used. Audio quality sounds the same on whatever device I pair the K1 with.
Just installed Neutron, comparing standard JNI driver and K1 driver, if there is any change, my ears cannot hear it. There is a subtle difference and I do me subtle difference between neutron and Spotify but I feel that is due to all of Neutron correction features etc. Either way, I can't tell which sounds better and there is no way I am trying to source 4000 songs just to play on Neutron for an inconceivable difference

This is weird. I installed USB audio player pro and as a result, I could get no audio through headphones using power amp or neutron. I had to uninstall usb audio player and then I got sound back. Any ideas? I restarted, but that didn't help. Usb audio player looked pretty good, but I couldn't figure out how to display album art.

Just bought USB Audio Player Pro today. No issue and works good. Gain and eq is nice. Played music from stock DAC cable to Jeep the whole 1 1/2 hour ride home, no issues(music from sdcard). Just tried with stock earphones and music plays fine in PowerAmp.

Thanks. I'll give it another try. I might have changed a setting that affected the other players.

Just using HTCs cheaper headphones I bought a couple months back. They sound pretty decent to me, but I can definitely hear the volume difference between 11 and 10. I'm hoping that HTC could add back the option to have custom profiles for different headphones/audio setups.

That could be a good sign that it's ignoring the universal USB host drivers for audio.
My K1 should arrive today. Let's hope it will work out.

Guys, don't you think we should talk about this in main thread as I wrote my thoughts about it? It would be tough to follow two threads which I'm sure gonna forget after a while. Also Hamdir confirms that we should be in main thread too.

And it would be good to talk about tricks and mods for the HTC adapter not only third party DAC :fingers-crossed:

It's getting crazier day by day. Received a usb c to micro usb cable without OTG.
Now the blue led from the K1 doesn't come on.
Tomorrow to a shop to try some cables...

Well just recieved the DragonFly Black v1.5 along with an Anker USB-C OTC Host data cable. Attached to phone and old HTC 3.5mm jack earphones and played a few songs through USB Audio Player Pro. The hardware volume is set at 50% and App volume is amazingly around 10% and its loud! Sounds is awesome too, will check tomorrow attached to Jeep Aux.

I'll have to grab a dragon fly black eventually. Just wondering what battery drain will be like. Hasn't been too much using the K1 but I know the Dragonfly can really pump out the volts

Great that it work out for you. Sound quality is indeed a lot better with a dedicated player like UAPP.

Android 5.1 head unit >>> USB Audio (DAC) output

Hi, I installed a MTCD Android head unit with Android 5.1.1 in my car two weeks ago. (I could'nt start this thread in the MTCD section because I'm new here)
My car audio setup goes as follow: Android Head Unit >>> USB Cable >>> PCM2704 USB to SPDIF adapter >>> SPDIF coax cable >>> MiniDSP 6x8 >>> 3 Amps >>> Speakers + sub.
So far I've been able to get SPDIF sound output with Neutron (Direct USB mode), Onkyo HF Player, USB Audio Player Pro, HibyMusic Player.
Sound is amazing btw.
If I understand correctly, all these apps are working with the USB DAC because they use their own app's USB Driver.
Important to know: All song in 44khz are playing fine, songs in 48khz makes every app freeze. I got a way around this by setting Neutron to resample every song in 44khz, so all songs are working now.
Now, if I play a song in Google Play Music, Spotify, Kodi, etc no sound comes out ... same thing for my HU video app, phone calls etc.
Is there a way around this ? What modifications can be made so every sound outputs to the USB Audio ? IE. kernel update, system files modifications etc ??
Thanks for any input.
Nobody use a USB DAC with his head unit ?
I have found this thread: http://forum.xda-developers.com/showpost.php?p=66707293&postcount=47
But I dont think it applies to Android 5.1, sound management is different.
i dont use any DAC on this head unit. But I do have a Dragonfly USB DAC on my computer. the Dragonfly Red says it works with Android. Not sure if that is just marketing, or if it doesn't something specific.

you would need to be using pre-outs, using a 3.5mm to rca cable into an external amp.
---------- Post added at 09:03 AM ---------- Previous post was at 08:57 AM ----------
interesting that you've tried this. This forces you to completely by-pass the HUs sound processing.
I have the same DSP, but I'm using direct pre-outs. I like this idea though bc it gets around the low pre-out voltage, and allows you to ignore the poorly implemented sound processing in the HU.
Unfortunately, you probably need to modify the filesystem to get this to work, as your link shows. Why do you feel the need to use a DAC in addition to the DSP?

my sub is tapped into my speaker wires, so I dont use the RCA preouts. So I probably can't try this.
However, I think my audio is pretty great with the Joying

Yes simply use headphones
We just need to know if audio is outputing from the DAC.
I would appreciate, thanks !

The DAC is a really clean source signal VS the head unit, I have a 2000$+ sound system in my car and sound quality is very important to me.
Also, DAC is digital signal VS analog RCA outputs on the head unit.

I agree. I feel like right now my HU is the "weak point" of my system. I am about the same as you, roughly $2000 in equipment (probably a little more).
focal KRX3 3-way active system w/ a cheap kicker sub + 3 amps. I have the C-DSP along w/ a line driver to manage the low pre-out voltage. Would love to take the line driver out of the signal chain if I could. All these components are taking up a lot of valuable space.
I hope you figure this out. I don't have a MTCD, I have a non-joying 4.4 HU. Would love to use the SPDIF inputs on the C-DSP as opposed to the ****ty pre-outs from the HU.

Nice ! I have 3 way peerless (tweets + 3.5 mids + 7in woofer) 1 pioneer amp 4ch for tweets + mids and 1 pioneer amp 2ch for the woofers, another JBL amp in the trunk with a 15in Alpine Type-R. I have the C-DSP 6X8 MiniDSp as well
SPDIF to C-DSP SPDIF Input would give you 4V at the MiniDSP RCA outputs

well you have convinced me to give this a shot. The USB DAC + 25 ft coax cable only set me back $35 on amazon. So even if this doesn't work I won't be mad.
The potential for 4V of CLEAN pre-out voltage is too enticing to pass up. The line driver works, but like I said it's another box that needs power/space/etc. The USB DAC also allows me to take the HU sound processor fully out of my signal chain.
I am unfortunately using android 4.4, so dont think I can help you much, but I will let you know if this works nonetheless.

If it dont work natively, I'm 99% sure it will work with the Neutron music player. Install it and then go to hardware settings and enable Direct USB Driver. :good:

well I tested this today and I am very pleased with the results. I really do notice a difference in SQ. It sounds "cleaner" and fuller.
Only major thing I notice is the overall volume seems really high over SPDIF. Only place I can adjust the volume now is with the DSP, but even then, I find I need to turn the gain down on the SPDIF inputs to get an acceptable volume. This is even with gain all the way down on my amps. This leads to a bit of clipping on the highs.
Did you make any adjustments in neutron player or the DSP to get an acceptable volume? Or do you get by with just adjusting the DSP master volume?
Now I just need to see if I can get all my sound to route through. I like to listen to streaming music too but I don't think I can go back to using analog pre-outs.

Great ! Now you're in the same boat as me lol
(Except for the clipping, I have no problem with that)
What is the model of your amps ? I have my gain to around 1/3 in the amps (They're up to 6.5V input sensitivity) and spdif input gain is at 0.
For your sound routing, you can sum the rca inputs and the spdif input together in the DSP And then you use your input levels to match the loudness. That way, you'll be able to listen excellent SQ music from Neutron and still hear BT phone calls, Youtube, navigation etc trough the analog inputs.

Yes! This is exactly what I have done. I spoke too soon also. The clipping was more a tuning issue than anything (changed cross-over on tweeters & lowered their output a bit). I was able to set the gain on SPDIF back to 0.
Man it sounds really good now. I haven't any real tuning yet outside of setting gains and cross-overs. I think once I tune the system it'll take it over the top.
I have a mosconi as100.4 on the tweeters and mids, and a alpine mrv-m500 on the sub. (i have one other amp I am replacing to power mid woofer, should arrive tomorrow). It's a total overkill system, but I find great deals on used gear on diymobileaudio classifieds so I keep upgrading lol.
So now I will use neutron for majority of listening, and by mixing channels together on the analogs I already had connected, I get acceptable SQ for phone calls and streaming music. I have no desire to mod my system files the way it was shown in that thread you linked. Looks too risky. I am okay with this new arrangement since 90+% of my listening is my personal music collection.
Really appreciate you making this thread. I always knew my system was capable of sounding better and this did the trick. I will let you know if I figure anything else out that could be useful.

For frontstage 3way I got a 4ch Pioneer Premier PRS-X340 running 2x NE25-VTS04 Peerless tweets and 2x NE95W-04 3in Peerless mids, another Pioneer old scholl amp pushing 2x175w for 7in Wavecor woofers. In the trunk is a JBL GTO14001, 1500Wrms @2ohm pushing a 15In Alpine Type-R sub in 3.5cuft tuned @21hz
All my amps are very good condition used gear found on classifieds too, you can dig some real treasors for very little money sometimes !
I've been looking all around the web since last week for how to route every sounds of the HU to a USB DAC, translating and reading about 500 pages worth of XDA/Russian Android forums, spent last nights editing config files all around my HU System folder, I tried the how-to link I posted in OP for MTCB units, nothing to do.. I really think the Kernel must be enabled for USB Audio for it to work, my DAC shows up in USB devices info but not in the audio output devices.
Well, I'm still happy because my FLAC music collection plays incredibly well i dont car that much for FM Radio SQ, I only wish I'd be able to listen to Spotify or Kodi on the DAC.
Im r eally glad if I could be any help to you and will keep this thread updated if I find something !

Any update on this thread ?
I made some sort of experiance, on Joying HU , the 2GB Rockchip Sofia version (10.1" screen) :
Using info from https: // source.android.com/devices/audio/usb.html - i looked into the "audio_policy.conf" file on the Joying, and for sure , there was no reference to any USB audio interface.
I am no android expert .. but i edited this file , with the info gathered from the link above , and after a reboot - the HU did indeed send the audio to the USB port.
Audio from all the apps i tred , was routed to the USB interface (Radio , DAB player,Kodi etc..)
The bad thing (?) - there was no volume control , all audio is at max level.
An external volume control could possibly remedy this.. i will look into it

Poor music quality using USB-C to USB connector in audi a4 2017...overloaded sound

Hi all-
I'm using this usb type C to usb connector inside my audi for playing music off of the Nexus 6p through the car's Android Auto:
https://www.amazon.com/gp/product/B010VFFSL4/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
I specifically got this one since it meets USB-C spec as many cables out there that boast high transfer rates can ruin your equipment. I'm using the latest WETA ROM and have tried a myriad of combinations by turning off/on Viper mod, configuring its settings, also tuning the eq in my car, etc.
What's weird is that music over bluetooth sounds like much better quality than wired with this USB type C connection. I got an awesome aftermarket sub and amp installed in the car but it seems to bring out the deeper issue. It's when music (mainly rock) has all instrumentals blending that the sound becomes distorted and overloaded. Because our phones already have poor max volume output, I'm having to max out the volume in the car. Also with android auto, you can't use the volume rockers on the phone it seems...seems to override the sound volume.
Anyone have any idea? In this car I can't seem to play music with aux cable (maybe an iPhone would work) and USB stick doesn't mount songs. Don't know if it's the cable I bought, the ROM (has the A.R.I.S.E. mod built in), or the DAC in the AUDI?
Thanks

An Audiophiles Thread

Hello,
I am trying out this phone due to it's built-in DAC. I have had other phones that I connected to an external DAC via an OTG USB cable. I have used USB Audio Pro and the Onkyo HF players successful to with good results. It would be nice to have a phone and a quality DAC/Amp/Player all-in-one device.
I noticed that with the Sprint variant of the V20, it only comes with the Google Music Player application. I don't really like the program very much as it is very limited in functionality. It seems to play all of my PCM and DSD files. I did notice, however, that my DSD files don't sound quite right. I believe that the Google Music Player application is doing a conversion to PCM first. Can anybody authenticate or rule this out?
I tried using USB Audio Pro and they claim that they are unable to play DSD files via the Android operating system. As a result, their application does a pcm conversion when an external DAC is NOT attached to the phone, but plays native DSD to a USB attached DAC.
The Onkyo HF player app seems to do the same thing.
Am I missing some settings?
Is Google play converting to PCM prior to output?
Is there a setting in the Onkyo HF Player app that needs to be toggled/adjusted?
Where can I get DETAILED specifications and instructions for use of the DAC in the V20?

Hello,
I am trying out this phone due to it's built-in DAC. I have had other phones that I connected to an external DAC via an OTG USB cable. I have used USB Audio Pro and the Onkyo HF players successful to with good results. It would be nice to have a phone and a quality DAC/Amp/Player all-in-one device.
I noticed that with the Sprint variant of the V20, it only comes with the Google Music Player application. I don't really like the program very much as it is very limited in functionality.

Whoa. Sounds like you are a connoisseur of good music, high fidelity audio files, and equipment that gives great sound quality. You've opened a new door for me to venture through. Curious to hear what others will reply to this thread...

Have you tried the stock music app?

Have you tried Poweramp? I'm pretty sure it will play hi res music files as is..

The stock music app for the Sprint variant is Google Play Music

Thanks for the suggestion but you are incorrect. It will only play PCM files and not beyond 48khz.
Someone uploaded the image of the stock music player - if you can't find it let me know and I'll try and pull it myself.
I use this app to enable the DAC for GPM (https://play.google.com/store/apps/details?id=com.phascinate.lgv10.dacfix&hl=en). You can really hear a difference flipping the on/off switch. I'm considering completely dropping GPM just because the quality is so much lower for no reason. Even on my G2 the same MP3s would sound better on the default player.
TIDAL also works natively with the DAC, almost as well as the stock launcher. The built-in DAC is far better than my Audioquest Dragonfly USB DAC I've been using

I am going to cancel my GPM too now that I have the 20 and just use tidal for streaming way better. Hoping they were going to have a better dac in the pixel and upgrade the music on GPM but didn't happen.
I don't have a subscription to the google play music service. I just have the app on the phone and it is the ONLY music player that comes with the phone. It is horrible for playing local music files.
Neutron. Try neutron first and see what happens. And maybe mx player pro though mx is more for video than audio but the type of audio you're using is something that might be embedded in a video file. Worth a shot.
Anyone have issues with gapless playback?
I've tried it with PowerAmp and Black Player and neither work.
Only time it seems to work is if I intentionally skip to the last few seconds of a song to test it.
My music is on my SD card but that really shouldn't be an issue.
Unfortunately, my suspicions were confirmed about the implementation of the ES9218 DAC:
The following is from the developer of the NeutronMP player:
According your logs (Thank you for making them!) OS declares only one
(!!!) frequency - 48000 kHz. You can see it in logs:
[13:08:16] I <SFX>| enum: device 0
[13:08:16] I <SFX>| enum: id = 1
[13:08:16] I <SFX>| enum: type = 1
[13:08:16] I <SFX>| enum: name = LG-LS997
[13:08:16] I <SFX>| enum: is sink = 1
[13:08:16] I <SFX>| enum: is source = 0
[13:08:16] I <SFX>| enum: channels [1]:
[13:08:16] I <SFX>| - 1
[13:08:16] I <SFX>| enum: sample rates [1]:
[13:08:16] I <SFX>| - 48000
[13:08:16] I <SFX>| enum: sample types [1]:
[13:08:16] I <SFX>| - 2
It means firmware does not expose Hi-Fi DAC via this new API. Why LG can not make it and expose DAC and solve the problem with using full potential of the device - puzzle. Neutron would use it automatically if DAC is exposed by the firmware.
Hi guys, and thanks for your information. Can someone point us toward how to use an equalizer effectively? I believe many times folks who put down simply don't understand how to maximize the benefits. In terms of real cans I have HE400s. In terms of ear buds I have the BOs and a set of HE600 ear buds. How do I understand how to maximize my sound and how do I use an equalizer (with Nuetron or other apps).
Thanks Guys
Do some research. Look at the frequency response of the source you're using and the frequency response of the cans you're using. Go from there. Unless you're a tech head st this and have proper equipment it is a little testing and tweaking. Like if you're mids are low on the source and cans you want up the frequencies in the mid range to get it back. But if you doing it blindly then it's a lot testing and tweaking.

Best Music Player for regular flac files, not high res?

What do people think is the best music player for the V20 for regular flac files, not high res? And do you use special settings?
PowerAmp

Any particular settings you prefer on PowerAmp? Like DVC, resampler etc?
So I compared Poweramp (With SoX resampler enabled) with the LG Music App, playing Dire Straits "The man's too strong" and the music sounded clearer and fuller with the LG App (44 KHz 1469 KBPS). I ended up enabling Direct Volume Control on PowerAmp and that improved it.
I do have DVC selected for headphone and BT. Crossfade @ 3000ms and gapless. The equalizer and preamp settings work great. I also save preset equalizer settings for use depending on what vehicle I am driving. I only use wired connections as I can't stand the sound quality of ANY audio player using BT.
If your download and store your music locally from Amazon it will find it(No player can access cloud to my knowledge.). It does not work with downloaded Google Play music in my experience due to the unconventional file naming Google uses(I havent tried lately though.)
I've been using the paid version of PowerAmp since my HTC Evo. Its worth every penny. I have yet to find a better app for music.
Neutron is good it processes the music at 64 bit if you enable it.
Also if you have the v10 dac fix on Google play the dac will work with all apps not just lg

I just thought I'd mention it but I personally like the layout of PlayerPro a little better than PowerAmp, I bought them both years ago and I think it's well worth having both of them but I'm not an audiophile by any stretch though either.
I have a question about the v10 dac fix if you wouldn't mind because I'm still confused about it, I was under the impression that if you have a higher end set of headphones or earphones it should kick in the dac no matter what music player you use, so I guess that's incorrect then? Also are there any visual clues that the dac is working? And what exactly is causing the volume controls to switch where it says "HI-FI"? I thought that meant dac was enabled and if so that happens whenever I plug in my headphones no matter what music player I'm using even though I've never installed the v10 dac fix?

[Q] VIPER4ANDROID With USB DAC? Audiophile's Im Calling you!

Hi I have always loved VIPER4ANDROID (the main reson to root for me) It has worked great with my sony MDR-XB90EX headphones so far(im a bit of a basshead). However recently i picked up a DAC PORT Slim from Centrance. All though it will play sound out of the headphones with pluged into the Usb-C port to much higher levels then the headphone jack ever would, VIPER says unsuppoted and will not work. I remember fixing somehting simillar with getting VIPER to work with Pandora, YouTube, Spotify, Etc.
When it is plugged android only recconizes it as a powered device (witch is good it does need power) but is there a config file I just need to add? Has Anyone gotten VIPER to work with any USB DAC?
-Thanks again

not working for me with dragonfly black V1.5.
audio is playing without any affect by V4A, when i connect the DAC driver status changes from "enabled" to "abnormal"
couldn't get it to work
I too have this problem.V4A was the only thing I rooted for, I'm on a pixel XL and USB out to Fiio Q1 amp DAC, it has a bass boost on it but that's it. Audio still works but the equalizer (or anything else ) has no effect on audio. Is there a fix for USB audio?
