Does the bluetooth audio also have a crippled sound level? Android phones sound like garbage connected to my car's AUX line because of the extremely low max level, I have to crank the volume to hissing speaker blowing levels just to hear it while driving and trying to listen to a podcast with the windows down is basically impossible, Apple devices sound perfect and I dont have to crank the volume at all so I know its not the radio's problem. Thinking of buying a Belkin bluetooth car adapter and using that if the bluetooth audio isnt lowered.
I'm running Timur's USBROM on my Nexus 7 with a Behringer UCA202 feeding through the auxiliary input in my car.
I'm finding the the volume level is lower than the other audio sources (CD player, radio). Is there a way to increase the strength of the signal or is my only option a line driver between the DAC and amplifier?
Thanks
Did you turn up the volume dial on the DAC? It's on the side
I just plugged in a cheap pair of headphones and wow, the sound is amazing using the hifi dac. I don't know much about it but I have a much better pair of Sony bluetooth headphones, is there any work around to use the hifi with bluetooth?
I don't believe so. I could be wrong but I very much doubt it.

This is a post from reddit user /u/codefyre explaining why the DAC can't be used over bluetooth (this was related to the v10, but applies to the v20 as well):
Not possible. Nutshell explanation:
All audio, the audio you hear with your actual ear, is analog. Sound is an analog vibration through the air.
The audio recordings in your phone are digital. MP3, MP4, whatever. Unless you're listening to an old record or cassette recording, you're playback source is digital.
The DAC is a Digital Analog Converter. A high quality DAC converts high quality digital audio into high quality analog audio. A higher quality DAC generates a better reconstruction of the original analog signal. Because wired headphones are analog, they simply transform the analog electrical signal into analog speaker vibrations.
If you think about this for a moment, you should understand why it can't be used with Bluetooth. BT is a digital protocol, so the connection between your phone and your Bluetooth receiver is digital. Bluetooth receivers typically perform an on-chip conversion of the digital signal to an analog output during playback. Some high quality BT speakers have onboard 24 bit and 32 bit DAC's to improve the fidelity of their audio output.
So, if the V10 allowed the DAC to be used with Bluetooth, your signal would be Digital Source - > Analog 32 bit HiFi DAC -> Digital Bluetooth -> Analog Output. Because your audio quality is limited by the lowest fidelity step in the reproduction chain, your final output quality is never going to exceed the fidelity of the conversion in your Bluetooth device. And because the analog -> digital conversion actually lowers audio quality, the highest quality Bluetooth playback can be achieved by keeping the signal digital until it reaches the output device. Running the signal through the HiFi DAC would actually result in lower quality Bluetooth audio.
If you want to match the quality of the HiFi DAC using Bluetooth, you'll need to buy a Bluetooth receiver with a high quality onboard DAC of its own.

Couldn't have got a better answer, thank you.
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.
I've tried couple of play test's
Bluetooth
Headphone
Build in speaker
And 3.5mm aux speaker connection
In all modes Dobly Atmos seems to work except connecting speaker via 3.5mm directly to speaker. The only thing which is active thru that mode is dac hifi mode but not dolbys equalizer.
So my question is for dolby atmos to work via aux do u need to connect via usb?
Im playing around so i get most of bass.
I connected 2 speakers thru 3.5mm splitter but dolby atmos doesnt work.

It works, no idea why it doesn't work in your case lol
You probably need V4A to 'get the most bass' though
