usb audio?

Whats the best ROM for USB audio to work flawlessly. My nexus 7 needs to be nothing but the head unit of my car hooked up to my fiio e10 USB DAC which will go to the amps of my car. Usb audio isn't working yet. Link me to the best ROM and kernel to do this please?

outputs
Is there such a thing? I thought that the nexus 7 had no outputs of any kind..

You need an otg cable. The only way it works is if I reboot the tablet with the otg hooked up to my Fiio E10 USB DAC. Ifni unplug the otg then my tablet freezes every time. It does that with my USB flash drive as well. I can't even access files on my flash drive. It sees the drive but it shows no files at all.

Bump. I need usb hot plug.

"Buzzer" sound through headphones when using OTG pendrive

Hi all,
When i plug my headphones and my OTG cable + 32Gb pendrive, a noticiable "buzzer" sound is audible through the headphones.
It happens when I connect the OTG and when I click on any of the the folders, a small "bzzzz" does sound.
If I copy any file from the pendrive to the internal Nexus 7 storage, the sound is persistent until the file is copied.
If I play a video file from the OTG, a "bzzz" sounds every few seconds.
I don't appreciate it when doing the same without headphones.
Seems like the "bzzzz" sounds when the tablet reads from the OTG-connected device and it's only audible through headphones.
This doesn't happen if I browse / play files from the internal memory.
EDIT: I'm using Nexus Media Importer, stock, no root
What do you think? Could be a kind on interference, a defect of the OTG cable, or somewhat?

same here using meenova OTG reader.
With Meenova OTG reader I found that if I pull on the headphone jack towards the usb connector, noise gets less loud.

It may have something to do with the USB port not being shielded well, or something to that effect.
I noticed that if I'm charging the tablet and hook up my headphones to listen to music, I get a lot of "static" noises, which is probably your "buzzing" noise. If I unplug it from the usb cable, it stops. This happens with any cable I use, including the original USB cable and eletrical outlet adapter that came with the table.
It happens even if it's plugged into a computer USB port, so I think it has something to do with the USB port on the motherboard and how it's wired. Seems like any power drawn on the USB port creates the buzzing noise when listening with headphones. Doesn't appear to happen when there aren't any headphones plugged into the port. Might be some kind of interference between the USB and headphone ports.

On the N7 the USB port and the jack are on the same board and use the same ribbon cable so l would assume its something to do with the voltages used in USB otg and PC connections as the ribbon is not consistently shielded that's probably where you are getting interference
Edit yes @iBolski the internal speaker comes directly off the motherboard whereas the jack output is on a separate board shared with the USB port

Anyone knows if extra shielding can be added?

No you can't add more shielding. The problem is that the same ribbon carries bothe the power and the sound signals.

[Guide] How to enable USB audio on Nexus 5X

The Nexus 5X's USB Type-C port can both input and output audio, however mine needed some setting up before it would work.
I plugged in a Blue Yeti microphone into the Nexus 5X using both the USB Mini-B to USB Type A cable (comes with the Yeti), and the USB-A female to USB-C male adapter from Google. The Yeti powered on instantly, it's red light turned on, and I could hear myself through its no latency monitoring via headphones (Blue Yeti has a 3.5mm headphone output), however the 5X would not recognize the Yeti as either an audio input nor as an audio output device.
I went into Developer Options, scrolled down to "Select USB Configuration" and changed the radio button selection to "Audio Source". I scrolled down even farther to the Media section, and there I disabled "Disable USB Audio Routing" (you might say that I enabled USB audio routing). There was no immediate effect, so I unplugged the Yeti, plugged it back in, et voila! The phone recognized the Yeti as both a microphone AND an audio playback device simultaneously.
I don't know for sure which of those two settings truly made a difference, as now that I've got USB audio to work, neither of those settings seems to make a difference anymore -- it seems as though my Yeti is permanently approved for USB audio in my 5X!
The USB audio works for listening to Google Music, and even for regular voice phone calls.
Do you have a USB microhone/headset/headphones/DAC? Get a good USB-A female to USB-C male adapter and you'll be quite pleased! And hopefully you'll be luckier than I was and it'll just work when you plug it in, but if not then toggle those USB audio Developer Options as described above.

Finally someone has posted on audio out and in via USB c! Thanks!

Just plugged the 5X into a Focusrite Scarlett 18i20. The phone recognizes the first two input channels and can record in mono or stereo (input 1 as left track and input 2 as right track).
Also it does seem as though you must keep the "Disable USB audio routing" off for it to work.

Sweet, guess I won't need the SoundAbout app anymore.

This is really nice. Able to route usb audio to a Cambridge Audio DacMagic. Much better than the on-board dac, and no longer tied to a specific app.

decided to add this on my index
[INDEX] LG NEXUS 5X Resources Compilation Roll-Up

Isn't this just a USB sound card over OTG? I plugged in a Logitech sound card with line out and mic in and it worked without any tweaks.

My 6th gen iPod nano plays usb audio perfectly fine on my crappy pioneer deh-3300ub headunit, but no matter what settings or cables I try the stereo says "N/A USB" with my N5X plugged in.

Anyone get the audio-in-via-usb to work with the built-in Google camera/camcorder app?
I am using Nexus 6P
The audio-in DOES work with this video app: https://goo.gl/Dtu14
But with the built-in camcorder, it only records audio from the phone's mic, not the usb mic.

I would think google designed it to only use built in microphone. It would take some mods or tinkering to get it to do otherwise.

Can you test and report which apps can record audio with the blue yeti? free and/or paid, if you have the time to test of course.

hi! I buy one of this adapter usb-c to 3.5 jack, beacuse my 3.5 jack has broken. I dont find how enable the output audio to work with my headphones. someone can help me? thanks!

That's because you most likely did just get a basic 3.5mm to USB-C adapter with no active circuit. I'm fairly certain that Nexus 5X do not support analog passthrough over USB-C, which means you will need something with active circuitry.

You need a portable DAC (get a cheap one like Fiio A1 for 25usd). Nexus 5X USB-C is not USB3/3.1 interface, so it won't work.

Note 4 (ENYOS) Aux LineIN problem

I have a Note 4 the Enyos octa core.
Today I tried to experiment by hooking it with a AUX cable to the computer, to see if it works and connect it in the car's radio afterwards.
For my best surprise, I am hooking it into the PC, TV, Creative surround e.g. noting works. When I plug they JBL J33s they work fine.
It's like the phone is not recognizing the aux cable, though it's a standard 3.5mm aux audio cable, there is nothing special about it.
I looks like this: http://s474818768.onlinehome.us/list/Aux Cable/002.jpg
There is enough clearance, as it clicks perfectly as the earphones do, the only thing that differ is the lack of audio.
I checked the cable with multi meter and everything is fine ground/left/right
I hooked the cable to an oscilloscope, but there is no signal present.
Do you guys have any clue why this happens ??
