Car in-dash: USB audio to receiver USB port? - Nexus 7 Q&A, Help & Troubleshooting

Working on an in-car mount. Has anyone found any way to run the digital audio out from the N7 via USB into a receiver's USB port? The receiver has a DAC built-in, it seems like this would be the ideal audio solution. Straight digital over USB into the receiver. Clean, simple, easy... but I haven't found anyone that has gotten this to work.
It appears to me the only thing you can use the USB port on a receiver for is putting the N7 into USB storage mode which allows the stereo to read any stored music files on your device. But this doesn't allow for Pandora, TuneIn Radio, Netflix, etc. It allows puts music control in the receivers hands, and I want the N7 to be the controller. I really just want the receiver USB port to function as an AUX audio input.
I do have Timur's kernel and CM10.1 ROM running and have successfully gotten my external DAC working with OTG and charging.... so that's the route I plan to go, but I could remove the external DAC and simplify things a little if I could just go all digital over USB directly into the receiver.
Thanks in advance for any thoughts from the crowd!

[Q] HDMI + Sound output?

Hi Everyone,
I plugged my A7 through the HDMI port to my projector, it works with no issues whatsoever! But the sound jack doesn't work once the HDMI is plugged. Is there a way to force the sound to work even if HDMI is plugged in? Or even the speakers?
Thank you,
Marc
I have run into this issue with other devices, not the A7 yet though.
Once HDMI was connected the device only wanted to send audio over it and disabled all others.
My projector had RCA L/R out, but no internal speakers.
What I ended up having to do was get a RCA -> headphone jack adapter from Radio Shack and use regular PC speakers from that.
Probably not the solution you were looking for, but I hope it helps.
Possible solution
The option I'm looking at right now is an HDMI switch. It has 2 inputs for HDMI and outputs 4 HDMI and an RCA. I'm not really insterested in dishing out the 70$ for it though.

Dash install noob - Any experts willing to advise?

I have a Nexus 7 (2012) that I want to do a dash install with. I would like to retain my head unit (already relocated) for audio, and I have a few questions.
I mainly want the following features:
-USB Tether
-Bluetooth OBD
-Airstream (or otherwise) phone calls from iPhone through Nexus
-WIFI backup camera
-Bluetooth keyboard?
From what I've been reading it appears Timur's ROM is the way to start. It looks like with an OTG cable and a usb hub I can easily do usb tether.
I have a bluetooth keyboard that has its own USB dongle, I'm wondering if with that dongle I can be connected to the keyboard and the obd transmitter simultaneously
I saw an app that was available years ago to support airstream, but it seems to have disappeared. Does anyone know a way I can have the audio/mic go through my nexus for phone calls while driving? (Right now I use Bluetooth through my head unit)
I found the following parts, is there anything I need to avoid? Or anything I'm missing?
Tendak (Pack of 2) Micro USB 2.0 On-The-Go (OTG) Cord Cable Adapter with USB Power for Cell Phone Tablets
ORICO MPU-5S Auto Universal converter car inverter 12V 5 port smart charger for iphone 5 5S Car Charger Adapter By AFUNTA
Turtle Beach Audio Advantage Micro II USB Analog & Digital Audio Adapter
I'm still trying to do more research on backup cameras, and the possibility of a dash camera. If anyone has any input on any of this I would greatly appreciate it! Thanks in advance and I look forward to being a more active member of the community!

[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

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.

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.

Le Pro3 type c audio

Because this phone will be using the usb c connection to transfer audio with, will it be able to use external dac's such as the audioquest dragonfly or the chord mojo with out the need for an app like usb audio player pro?
The whole idea with usb audio is to remove DAC from the phone, enabling best audio earphones can produce. Which DACs are supported, I don't know.
With my Pro3 i just needed one of these: goo.gl/uGYUH4
My Oppo HA2 works perfectly with it.
Does the ordinary headsets with controls on wire like answer button or volume keys work with usb 3 adapter?

Micro USB to 3.5mm Audio?

Hi all,
I'm looking for a way to use my earphones with 3.5mm audio jack via the micro USB port. Ideally, without carrying around a bulky separate amp. I bought a small micro USB to 3.5mm jack cable but it doesn't do anything straight out the box.
I don't know if i just need some sort of software to get the cable I've already bought working, or if I need some other sort of hardware.
Reason for all of this - I managed to break my 3.5mm audio output (plugged it in to a cheap ebay car audio unit and have blown something). I have wireless earphones....but just don't like them as much as my original wired ones!!!!
Hopefully someone can help me out!!
Cheers
You will NEED external DAC and AMP.
Micro usb can only output digital signal.

You need a USB DAC. There a quite a few like FiiO Q1, AudioQuest Drangonfly, Oppo HA2-SE, Chord Mojo etc. Money is the limit
By itself micro USB does not transmit sound, it transmits a digital signal, you will need an additional USB DAC
Get a quality Bluetooth receiver. Here's a great one with apt-x low latency which is crucial for video.
