USB audio enabled? - Nexus 4 Q&A, Help & Troubleshooting

Anyone yet tested the audio out capabilities? Shame that to date the Galaxy S III seems to be the only phone able to send unprocessed audio out to an external DAC.

[Q]Music App straight to DAC

Good afternoon,
I'm trying to work out if an app is feasible. I can hear the difference between a few music apps such as winamp and poweramp but wondered with the galaxy s3 and 4 having dedicated high quality audio DACs is it possible to bypass any processing and send data directly to the DAC. On Windows if you have an external USB DAC you can use kernel level hooking to bypass any Windows drivers that may get in n the way of to the the audio signal to the USB DAC. Is that type of thing possible on android to improve on the Sonics, or could someone advise on a must do in the coding to make the app playback audio as best it can?
Thank you

[Q] Galaxy S-IV (S4) confirmation for AptX audio

Hello,
As the title says , is there anyone who can please guide me for the following queries :
1. Does international Samsung Galaxy S-IV supports AptX audio compression for bluetooth audio streaming. I am a bit confused, although it is listed on the AptX website as a complaint device smartphone, some other places list only Galaxy S-IV Active as the complaint device. Would be nice to know which model variants of S4 support the aptx.
2. Would be nice to know about how to confirm that it supports Bluetooth audio aptX (any terminal or ADB command ? ), will this command even output the presence of aptX , even if the mobile is not paired to an aptX complaint device and actively streaming the audio. I am asking since I dont have an AptX enables bluetooth headphone or speaker at the moment, although I am researching prior to buying one.
3. If connected to an aptX complaint device , do we have to use the stock android ROM Music or Media player to get the benefit of aptX audio streaming. Or we can use any media player of our choice (like MX Player, Wondershare or even the ported Sony Walkman App) while running the stock ROM. I am running the stock WanamLite ROM 4.2.2 and prefer the ported sony walkman app for listening to music.
Would really appreciate the feedback and opinions for the queries, which are not only for me, but would help the community at large.
Thanks for your support.
So many views and not a single guru to advise and answer....surprising at the least....
Keeping the fingers crossed....
Pending my decision to buy aptx enabled Bluetooth headphones...till the queries are answered....hope these may help a lot of others like me.

Same doubt
I hace the same doubt in my case I do hace an aptx enabled headphones but I dont know if the feature is being used
I used S4 with an car adapter from htc and if i remember well the color from the led was different for the aptx/nonaptx. From what i know/remeber S4 has aptx.

Anyone using their tablet with an external DAC?

Hello,
I have the Samsung Galaxy Tab A T580, I bought the dragonfly USB DAC that I connected to the tablet.
The issue is the notification sounds are not routed through the DAC, they come out the tablet speakers very distorted when I plug the DAC in.
Music and Voice go through the USB DAC with no problem, it's just the notifications sounds that are not routed through the DAC.
Anyone else has experienced this issue?
I use the BEHRINGER DAC with a Samsung Galaxy Tab S 8.4"
Are your notifications sound routed to your DAC without any issues?

The U11 Audio Thread, Standard adapter and third part USB Amp/DAC

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.

Galaxy A5 - Logitech USB headset works for media audio, but not for call audio

I have a Logitech H340 USB headset, which works fine on my laptop and, with a Type-C to Type-A adapter, works fine on my personal LG G5.
But on my new work Samsung Galaxy A5 (2017), call audio doesn't use it and I can't find any way fix this. Media audio and system sounds do go to the headset.
If I receive a call, the ring tone sounds in the headset - and then the call audio reverts to the phone! The UI only has buttons to switch to speaker (which switches only to the builtin speaker) or to Bluetooth. This is crazy.
Any suggestions / answers?
Bonus question - Skype and Skype Business have audio test features. Does anyone know a (UK) call audio test number / service?
