[Q] Audio over USB with Android 5.0 - Nexus 4 Q&A, Help & Troubleshooting

I know there have been threads in the past about the Nexus 4 not being able to support outputting audio over USB, but now that stock Android 5.0 supports it, can the Nexus 4 do it?
I'm using the factory 5.0 images and I have an external DAC/amp that I want to use (Fiio e18) that's made for Android, but nothing seems to happen when I hook it up. I've read posts that the Nexus 4 physically can't output power over it's USB, which is fine because the DAC has it's own battery source... but can it at least output the audio?
I started with the stock kernel, but also tried the latest Franco kernel (r214) with no luck. Also, I verified the DAC itself works by using it with my laptop. I'm hoping there's just some hidden setting or patch I need to apply to get it to work... Has anyone else tried this yet?

pls report your findings if you can make it happened!!
i can not help you with your problem but it is something that interest me too. i only can suggest to use a more feature enabled kernel like unleashed or hells core
pls report your findings if you make it work mate!

That's a good idea... unfortunately no dice with the latest unleashed kernel either (98u). It claims it supports USB OTG, so I was hoping that would be enough, but maybe there's more that needs to be done.

one thing that you might not know. nexus 4 does support usb otg BUT cannot provide electricity via usb. you must use a y cable and provide external power so you it might not be possible to use your DAC!

Thanks, I did know that, but I figured that since my DAC is self-powered (it has its own battery) that I wouldn't need to do the y-cable trick.
Worth a try though, I'm going to order one and see if I can at least get regular USB OTG to work. Maybe once that's working it'll be easier to troubleshoot the audio.

Just wanted to update, I got the Y OTG cable so I could have external power at the same time... but still doesn't work. This is with stock 5.0.1 and unleashed 98u kernel. I went into Synapse and enabled the OTG setting as well. DAC doesn't get recognized, and I tried a few free apps that are supposed to do OTG checks, but they all came back that nothing is attached.

Usb otg is one thing and uab audio out is another. USB otg means that you can connect an USB stick or external hdd to your phone ( with or without external power) USB AUDIO OUT need special circuits from your internal Dac to the USB. If those are not implemented you will never have USB audio out. This is something witch depends on the manufacturer ( S4 mini with snapdragon 400 don't work with USB otg or USB audio out, htc mini 2 M8 works perfectly with fiio E18 as a audio surce for external DAC). So if you really need USB audio out please next time do your homework and read before buying a phone. P.S. Htc mini 2 M8 has the best audio ever and really you don't need an external dac. If you need more power just use your fiio as an amplifier with your phone.
Maybe you could find for your phone a apecial kernel modified for better audio experience. Flash that and use your headphones.
Good luck!

Thanks, yeah I don't need usb audio out... I've had the phone for over 2 years and I still really like it, so no plans on getting a new one just for this.
I believe it's physically possible to do audio out on the N4... I've seen random posts about people getting it to work, but they've all been on custom ROM's based on 4.4.x stuff. I'd really rather not try to reproduce that since 5.0 is running so much better on my phone, and I was just hoping with the new native Android support it might work out of the box. But alas, it looks like google locked down 5.0 on the N4 - even USB OTG storage doesn't work unless you put a custom kernel like unleashed on.
In the meantime, I've just been using it as a headphone amp like you suggest and it's a big improvement.

[Q] OTG USB Audio possible without reboot?

Does anyone know of a kernel allowing users to "hot plug" a USB DAC to get audio out?
Poitee and Trinity seems to support at least USB audio after a reboot, but so far I have had no luck identifying something that will simply allow me to place my Nexus 7 in my dock (with OTG USB DAC connected) and have the audio automatically routed through the external USB DAC.
Therefore, does anyone know of a rom/kernel allowing this (since my Samsung Galaxy S3 can do this)?
No one out there who knows? :crying:
I'll second this. I am installing my Nexus 7 semi-permanent in my Car, and i'd like to take it out and use internal sound without rebooting it every single time.
// Per.
Yeah, I was keen on making a car install too, but this is for a dock I am building.
I can tell you it involves B&O design and pure awesomeness, guess I cannot post images or give links until I reach 10 posts though.
Hotplug USB audio is indeed possible on the Nexus 7, it seems that a few of us all have similar plans for our Nexus's

using external mic and an app like garageband (as on iphone)

Hi, I can't see any way to plug an external condensor mic into my new nexus 4, pretty bummed if that is the case.
I would like to use my phone as a portable recorder that can record sounds in at least cd quality and use some sort of mic I will have to buy.
Much like everyone is doing with their iphones and garageband, maybe the nexus isn't able to do it, there is no hardware problem, my 1st ibook with a 512 mb memory could do this without a single issue, I imagine this device can do it but maybe it isn't made with any thought of getting external audio into it ?
Makes me thing I need an iphone after all.

USB OTG (On the go) is not supported in this phone by stock. None of the developers have been able to figure it out as of now but it may be possible. Another limitation is the voltage the USB hardware is able to provide which we do not know for sure yet. If it is lower than usb spec (and hence USB OTG is not supported stock) then you won't be able to power your mic with the phone.
TL;DR No this phone won't accept your usb microphone, maybe in the future with further research by devs.

That really sucks, lol.. and it did say this phone has "OTG" usb on the google page for the specs for the phone, no ?
Now i see why i need an iphone, i can't even find a note taking program i can manually sync between mac and android (like I did with my blackberry for 10 years) without using cloud storage and stuff, I don't want my stuff on a cloud.
Yes the original marketing material referred to the device having USB OTG. It was removed sometime near release and the rumor we have is that the device can't provide the full 5V required by USB specifications.
As far as no cloud solutions, I'm not really sure what your apprehensions are. Apple is going to sync your notes the same way Google/Evernote would. The days of using a cable to sync your device have passed.
he's trolling...he knows this phone doesnt have OTG
Closing thread.....

[Q] Is there is a ROM or kernel with FULL USB Audio Support?

I would love to use USB Audio on the Nexus 10 such that I can use it when it is playing music from google play music, or locally through the stock music player, NOT through USB Audio Recorder Pro.
I have a Nexus 10 and a Verizon Note 2, both stock unrooted, and it's frustrating because the only way I can enjoy USB Audio on those is with USB Audio Recorder Pro.
Since my Verizon Note 2 is from work, that leaves my Nexus 10 which I could root, unlock, and load a recovery and a ROM (well I have a touchpad with 4.2.2 rom, but I can't even get the device to recognize that a USB audio device is plugged in, but I really want this on my Nexus 10). Is there a ROM right now (or a kernel that I use with the stock ROM) that has full support of USB Audio so any DAC I plug in via USB (With USB OTG cable, of course) will work for any audio coming from the Nexus 10, not just using that USB Audio Recorder Pro app?
Thanks!
I remember this coming up all the time on the Galaxy nexus as well. A couple kernels added full support on their end for all the modules required to use a USB DAC, however the ROM side of things also needs to have special parts included to make it work and I dont think anyone really figured out how to do that or every ROM dev simply didnt want to. So most likely you will always be stuck using whatever app you use to make it work.

USB Audio Note 4

Had Iphone 6 USB on my 2011 Buick Regal USB Audio worked flawless, my wife's phone LG G4 works great.
Got tired of apple & decided to go with Samsung Note 4 now I cant get it to work, tried multiple cables, update to Lollipop 5.0 & 5.1 & none of these worked.
Called Buick they said I should use AUX cable instead, obviously I did not like that response.
DoI need to root? or is this a lost cause.

I would post a link to a website with pictures and information about what you are talking about as I have no idea what that is.
Once I understand what exactly it is I might be able help.
Just guessing but are you talking about some kind of headphone cable that uses USB to connect instead of jack?

Link attached is the USB port in car, you plug in any IOS device or LG apparently & it picks up the audio being played.
The Bluetooth feature doesn't support audio, was relying on the USB port to play music in car over Google Play.
Before getting android I tried a Samsung S4 Active & it would appear it registered it but would immediately disconnect on both sides.
I figured it was hardware side as my wifes LG G4 worked perfect decided to switch my iPhone for a Note 4 & when I plug it in the USB nothing happens.

OK link is useless as I cannot click it.
Have you checked if the company you got the USB from makes any kind of app or driver to use on some android phones?
I can assure you Bluetooth audio works very well as I use it often with my Bluetooth speakers. I also used it to stream music to my Sony car stereo via Bluetooth.
I have never used the USB to stream music but I know that there is an app that does some thing to make phone simulate a USB stick so if you where to connect the phone via USB to a stereo deck it would play the music on the deck from the phone.
Sadly I cannot remember what it was called.

copy link & replace (Dot) with a . , 2011 Buick does not support Bluetooth audio.
I've heard of this app but it required root, I'd be willing to root the phone but the amount of Firmware & versions seems like asking for trouble.

Well I can't copy as I use tapatalk.
www.google.com
Easy to make a clickeble link.
OK so that buick thing is not the USB cable so I assume it's some kind of speaker system.
Regarding the root. Custom roms are much better then bloated stock roms in my opinion so it's well worth it and specially now that Note 5 ports are out.
Plus even if you wish to keep stock rom just rooting it will give you full ownership over your phone but nonrooted users can't really say the own there phones as both Samsung and phone company have more control over your phone then you ?
Anyways I strongly suggest you at least root the phone. No need to change firmware if you don't want to but the rooting process alone will give you unlimited freedom with the phone beyond the possibility of icrap can offer with jailbreak.

Do you stream through USB or using MTP & treat your Phone as a USB Storage?
EDIT:
I found this thread & I hope it will help you.
USB Flash Drive use in Audio System
There's a possibility that your Note 4 microSD card was formatted using exFAT & the "old" Buick USB system can't recognize it.
Try to use FAT32 (with its inferiority towards exFAT).
Another solution is using AUX (Draining Note 4 battery)
Last resort is using USB flash drive
NOTE:
Some system can only recognize limited size of USB storage.
Some are limited only to 4 GB, some can only read 32GB & won't read anything with larger capacity.

Sorry for asking this, but do you know what streaming means? (no offense )
If you are streaming the music, it means you are playing the music from your Mobile Phone & direct the sound out of it through either USB, Bluetooth or AUX.
So Streaming will drain your Phone battery.
Usually, car USB system doesn't do this.
Car USB system usually access any device connected through USB as a USB Mass Storage Device & then play the content using its own built in Audio System.
Have you checked the link I gave you?

My car USB does have this feature can play audio of a youtube vid, google play radio, pandora, ect over USB on selected devices it seems.
As stated above it works fine with an LG & IOS phones but has yet to work on Samsung.
Thought there could be a quick fix out there, but that doesnt seem to be the case.
More likely going to swap my phone out for an LG if I can find someone willing.
Worst case scenario I have a iphone 4 which I will use via hotspot in the car.

Do you mean that you play your media on your Car System?
If you do, then check your microSD.
May be your LG use FAT32 for its microSD & Note 4 use exFAT for its microSD.
Some 2011 car systems can't recognize exFAT filesystem.

Thanks for suggestion but it did not work, for the meantime using an Iphone 4 via hotspot for my normal commute I just use FM radio.
Was thinking maybe I can have hotspot automatically turn on when I'm in my car but that might be too much to ask for with current technology.
You win some, you lose some this one I lost no one interested in changing Note 4 for LG G4 in my area.

[Q] Charging in USB-C OTG-host mode

Hi guys,
I am using a pass through-powered USB-C hub through which I am using external USB devices (keyboard and mouse), as well as a larger monitor for screen mirroring. This works reasonably well. However, the USB-C hub, while powering the external devices, does not charge the phone while it is in OTG host mode (which is needs to be in order for the external devices to work). This leads to the problem that the phone is slowly draining when external devices are used to play games, work on spreadsheets, or whatever. So, I was wondering why this is and found that OTG host mode charging seems to be restricted by the kernel. Very annoying!
Looking around I found that there are custom kernels for other phones that tackle this problem (examples here (OnePlus One) or here (for Xperia Z5 compact)). Which leads me tot he question: is there any known solution for this problem for the OnePlus5? Is there a custom kernel supporting charging in OTG host mode? Is there any other work-around that would allow me to power my device while using OTG?
Thanks!
PS: My device is rooted but is otherwise running on stock kernel and ROM.

Nope and it won't, I have a thread in the themes and apps section about targus display docks as after much research I found that it is the only way to reliably mirror your screen in real time with no latency issues, with that being said there is no charging whilst this is in use, I wish there was but there isn't.
It's possible I suppose that power could flow both ways but after all the time that I've spent looking, I'm yet to find it.
I've tried over 10 docks, splitters, dual output cables. Devices with power input, none have charged the device.
I think the nature of the way display link works it just doesn't allow it.

Yeah, it is definitely possible (see the threads I've linked). But it depends the kernel allowing it, from what I understand. Anyways, if nobody has come up with a kernel allowing for it, then it won't happen I guess.

With displaylink technology it's not possible.. with previous hardware ie the HTC 10 it was but only with standard usb to hdmi converters, displaylink doesn't allow it.
In regards to usb OTG cables, I've never tried.

Oh.. so then there is a second limitation based on DisplayLink. Aside of the kernel.
Well. Luckily the OP5 has great battery life. A few hours of activity is no problem. Especially since I run everything through a USB-hub with its own power source anyway.

From my tests I've found the hub being powered makes no difference to the drain of the battery on the phone..
The OnePlus has got amazing battery life, definitely something I need in my life for my next device..
In regards to charging whilst using a displaylink honestly my comment is based on the testing of around 20 different devices and none of them allow charging, if it exists I personally haven't come across it.
A shame but not the end of the world..
Lava - Simulcharge
For what it's worth, I had a difficult time finding a device which supports simultaneous host charging as well. As it turns out, there is a device called the Simulcharge from Lava Computer that works quite well on Samsung tablets. I'm not sure if it will work with other Android devices: (unable to post link - search amazon).
It's a bit expensive but it works great!
Is there a cheap displaylink that works with the OP5 that also has a USB port for peripherals?
Sorry to revive this thread from the dead, but I'm also looking for a way to connect both charger + USB-OTG at the same time. I have a USB C hub that's capable of that, it works perfectly fine on my Oneplus 7. However on the OP5 it's either OTG or charging.
Did you ever found a way?

Hi ! I have a custom app specifically developped for OP6 and have the issue you have on OP5 : otg OR charching. I have seen Krieg Kernel enables it on OP5. Have you tried it ?
