USB Audio Out? - Nexus 7 (2013) Q&A

Does the stock kernel support USB audio out?

Bump
I would also like to know if USB audio out works, wanting to do a 2013 Nexus 7 car install

No, it does not. One of the first things I did was to connect my DAC through a OTG cable and it does not work. DAC works perfect with my HTC One.

Thank you, guess we will have to wait for kernel support

Thank you for confirming this. I want to do a car install with it in the future as well. I guess the Sero Pro is an option as well.

Any people already try the 2013 Nexus 7 can use the usb audio???

Connecting USB Key or USB HDD to One X

Hi Guys.
Loving the ability to hook the HTC one x via MHL > HDMI to the bigscreen.
Does anyone know any news on the ability to hook either a USB key or a USB HDD to the one x.
I understand that the one x hardware supports host mode, but no softare does at this point. From reading a few other posts around the web, there was some scepticism as to whether it ever would.
I personally would love to be able to take the one X and hook up extra storage for movies etc
Any change cyanogen or miui will support this ??
Doesn't work, tried it with mine (also others confirm it doesn't presently work). Even if HTC never enable it I'm sure custom ROMs will eventually.

I could Be Wrong But Does Leedroid's One X Rom Support it in his latest update?
Might be worth a look?
Thanks

I'll get my USB OTG cable tomorrow if I'm lucky. Will report back
Try something like USB Mass Storage Watcher (market: OTG version or non-OTG (I use this on my Toshiba Thrive, which has a full size USB port ).
It does have this warning:
USB Mass Storage Watcher OTG Market Page said:
---- ATTENTION ----
This will only work on rooted devices and requires a kernel that has the ums enabled. An OTG cable is required for using usb keys. It also requires a kernel with ums enabled and modules for ntfs/hfs/hfs+ etc.

Really? It doesn't works on the unrooted stock ROM? I saw Note 2 doing it in stock ROM even with a cheap cable...

You are replying to a thread 7 months old... It works on stock JB now.
what about use usb device + mhl (hdmi) output?
is it possible in official JB rom, use mouse+keyboard and hdmi output simultaneously?
Which cable do I need to do this? I have now stock JB... A cheep one, please!

Confirmed that HOX with stock JB Rom directly connect with USB storage perfectly by any OTG USB cable.
and no one can't check it?

Probably not possible. I've never seen an MHL cable that also has usb slot.

MHL to HDMI cable has USB for external power supply.

[Q] USB DAC support

I recently purchased a USB DAC/amplifier combo to use with my high end IEMs on the go, as well as my sennheiser HD650s at home. They sound/work great with my nexus 7 (cyanogen mod 4.3) with just the stock kernel (faux's kernel works also)
However, i cannot find a kernel for my trust old Gnex (gonna use as a mobile digital audio soruce, the amp dac/amp is tiiiiiinnny but the tablet is so big its just not portable, and my Moto X doesnt support USB audio and has no custom kernels, for the first time I am wishing i had gotten an s4 as even the stock kernel supports USB audio.
So far i have tried: Faux123,
Franco.Kernel,
Glados 2.3 (downgraded to 4.2.2 just to try, and even after loading the modules, nothing..)
and finally stock CM.
None of these even came close to seeming it was registering at the least, much less delivering auditory bliss.
If i need to compile my own kernel and just add in USB audio support, I would love to learn,
ideally though, I would just love to find a kernel that meets my need, rather than having to create one.
Thanks in advance,
J.P.
First off, HD650s rock. Nice choice. Also what DAC/amp?
Anyways.
I somehow recall something about how the kernel version the GNex is on (as opposed to the 3.4 kernels a Nexus 7 totes) does not have any USB audio support. I might be wrong.
Android just rarely caters to the audiophiles, sadly.

I add my question!
Me too try to use my Gnex with the Fiio E18, an USB DAC/AMP that seems to work with many Android device.
When I try to connect the DAC, it seems to be recognized (a red led becomes pink, wich means that the DAC is "connected" somehow), but no sound comes out.
So the question is: the problem is software or is also from the Gnex hardware?
On a thread on head-fi, James (a Fiio employee) says that is a hardware limitation...
But I know that the Gnex can work with pendrive and an OTG cable (I've got mine and it works!), so on the hardware side is this not enough?
And new Android KK 4.4: how it is regarding USB Audio?

4.4.2 enables USB audio out!

Well I am extremely happy right now.
It turns out that with an OTG cable, my 4.4.2 RAZR M can suddenly output audio via USB to my Fiio E17 amplifier. I can finally ditch the 2G iPod touch I have been clinging to for years.
Awesome. Will test with a Droid 3 dock as well

I am just starting to explore the possibilities of using my M for high quality audio. Does the above work without root, custom rom, etc.? I am not rooted and am bootloader locked and need to remain that way.
Are there any decent guides available on the net on this topic? I have been doing a lot of googling and trying to piece things together but haven't found a good consolidated source for information.
Thanks much.

Worked before I even rooted, all stock. Just used and OTG cable and connected it to my DAC/AMP.
Is there a USB sound standard I should be looking for to find devices that work? Or does it work with any USB sound device?

It's called 'class compliant' USB audio device.
If it works on Windows, Macintosh etc. without the need to install a device specific driver, it's probably class compliant.
Btw., the support for OTG connected class compliant USB DACs has been present in CM builds for Razr M/HD family since September 2013.

That is true, but seeing as I need Bluetooth in all its glory and some other things that never seemed to work right in CM11, I am glad to see it in a stock build

:good: Was able to pick up for a whopping $1.04 shipped, a USB audio dongle from eBay which works great, but needs external power.
Now if only I could get PodMode to work, I'd have a perfect 1-plug replacement for an old iPod.

[Q] Find 7 via OTG into USB DAC. Will it work?

Looking to output signal out of the phone into my USB DAC. It works with my current phone, quite well.
If I'm to buy this Find 7 I need to know that it will work first. Anybody have any experience with this?
If I remember correctly find7 doesn't support USB OTG at all. Someone can correct me if I remember wrong

The Find 7 supports OTG, but if it's supports a DAC, I don't know, I've only used for usb storage, keyboard and mouse.

My mistake. It was MHL then that was missing
I'll let you know if it works with my DAC, soon, as my phone is slated for delivery today.
MHL, what is that? Hi-rez video out to an external device?

Yup. Standard that allows HDMI output from usb port. I use it a lot with my tablet.

USB Audio doesn't work?

I just bought a Fiio K1 USB dac/amp to use with my laptop, but I also read that it works with some smartphones via an OTG cable. So I hooked it up to my S6 with my OTG cable and it didn't work. Sometimes I would hear a weird static noise, but otherwise my music wouldn't come through any output while the K1 was plugged in. I then tried my same OTG cable and K1 with a friend's Verizon S6 and it worked flawlessly. Both of our phones are running Android 5.1.1. What's going on? Did Sprint butcher USB audio on the S6 with their custom ROM? I'm really disappointed.
If anyone has gotten USB dacs to work with their Sprint S6, was there anything special you had to do first?
first it was hml now this. I'll try it later tonight

thank you for the usb audio idea. I tried it on my phone, my usb dac works fine on the sprint s6. im using hacker kernel, perhaps that makes the difference?
BTW, I had to update the firmware of my usb dac so that it can work with android phones.

I would assume it works for you because you are running a different kernel. I can't know for sure though until someone other people can chime in. Thanks. I would go a custom kernel route but I got out of the rooting/modding scene a while ago.
After upgrading to Marshmallow, this still doesn't work.
Have you used OTG Troubleshooter to see if your OTG is working correctly? Also try using Onkyo HF player and USB Audio Player Pro. A lot of phones that don't natively support USB audio will work through those apps.
Getting the same here... A bit of occasional "digital static" (like old cell phones near a speaker) when I start a track, but that's about it. Often the progress indicator won't even start on a track. However, "Neutron Audio" does show that there's specifically a Fiio K1 connected, and Android (7.1.1 CM14.1 based on hsbadr's Note4 builds) did prompt me to allow Neutron access to this audio device.
