usb-dac vs 3.5mm or usb and equalizer - Nexus 7 (2013) Q&A

I was reading and saw most use the Behringer UCA202 USB DAC. Can I use the 3.5mm port that is part of the tablet and run that to the equalizer. I also saw that soundstream makes a usb port into one of there equalizers so I was thinking about using that for my install. What are your thoughts? Will I have any trouble with timur's kernel? Sorry if my spelling is bad.

[Q] 3.5mm to standard USB for car stereo music? [RESOLVED - IT'S NOT POSSIBLE]

Anyone know if I can take a 3.5mm to USB cable. Plug the 3.5mm end into my headphone jack on the phone. Then plug the USB end into the USB port on my car stereo, and listen to music that way?
I know there are other ways of listening to music, but I need the answer to this particular question for something more complicated that I'm researching.
No, can't be done.
And the only way to connect to car is with SGS3 Easy UMS.
Our phone's 3.5mm headphone jack is TRS (headphone) or TRRS (headphone and mic) only. Devices that use the 3.5mm port as a USB port specifically state that and only support charging and USB data (to put music on the device). You would need a separate device to convert the analog audio out of the 3.5mm to digital and stream it over USB and even then your car's headunit would have to support streaming digital audio over USB. Our phones do support streaming digital audio (USB audio host capability) out the micro USB cable though.
Bummer, okay thanks guys.
I think I posted in the wrong forum also. Sorry about that.

[Q] Need Help for USB Dock Audio

Hello,
I have FiiO E11 portable amp which I can use with E4GT through 3.5mm jack. By doing this, the audio is converted and amplified by internal amplifier of the phone. I just want to bypass audio through micro usb port, so sound will be bypassed through phone's internal amplifier and go directly from Phone -> FiiO E11 via micro usb to 3.5mm cable which will be more pleasant to hear.
Question is - Does Cable like below work for this purpose?
www.amazon.com/Generic-Charger-Cable-Galaxy-I9100/dp/B00B5T4ELQ/
I also found that JB 4.2 Dock audio is not working well. I am currently on CM10.1 JB 4.2.2.
All suggestions and inputs are appreciated.
Thanks,

[Q] USB Audio..

Hello guys!
I've just bought a Nexus 7 to integrate in my car dashboard. Actually I didnt had so much knowledge about it before I bought it, (I only wanted the best and I hate apple so) but I didnt thought it was junk. And that's the only thing I wanted, a non junk tablet that could play music and works as a navigator without hardware-buttons.
My old stupid Iphone 4s worked perfectly for playing and streaming sound from spotify trough a regular usb cable to my headunit, so I didnt even reflect that googles new flagship wouldnt be able to do this simple task. But it seems like it doesnt work..
I've searched for answeres but the only thing I can find is to buy a usb DAC that converts the digital audio to analog audio but then I lose the whole damn point. I want digital audio in to my headunit. And my stupid old Iphone do it great, why the **** can't google flagship do it? Feels like I have bought a extra thin rock from the stone-age.
Please tell me I'm wrong and this is possible somehow. Otherwise I gotta throw this stupid f***** sh*t tablet in the garbage as fast as ******* possibly..
Sorry for my rage.. I just feel so fooled.. I've just bought a 400$ angry birds game. :silly:
You have a couple of options:
1. Use headphone output jack from your Nexus. Hopefully your car audio headunit has an auxiliary input.
2. Bluetooth! This is what I use in my car. If your car audio headunit has bluetooth built-in, then you don't need any cables at all. Just pair your car audio to your Nexus and start playing music! If your car stereo does not have bluetooth, then you need to purchase a bluetooth car kit. These connect to an auxiliary input on your car stereo (just like #1 above). There are bluetooth kits that also stream through an FM modulator, but that should be used as a last resort as sound quality suffers materially.
I installed an Alpine bluetooth car kit and integrated it with my factory car stereo system in a 2005 Honda Accord. Since I did not get the factory CD Changer option, I had that one input open to use with the Alpine Bluetooth. I'd post a link to my YouTube video showing this, but I'm now allowed to post links yet since I'm new to this forum.
The two options listed above are the only ones I'm aware of. I'd love to hear from others if there are other options. The only drawback to both options is that you use the DAC built in the Nexus, you don't get to pass through to a better quality external DAC. The only way around that is a Slimport adapter which uses HDMI. I don't know of any car audio units that have HDMI inputs.
What you want is achievable. Nexus 7 2012 works best with Timur Kernel however Nexus 7 2013 with an AOSP build or stock with Elemental X kernel can have a USB DAC with an OTG Y cable that will simultaneously charge.
If you have Cyanogenmod you may need glitch kernel which does the same thing.
I have a HiFiMeDIY DAC and OTG Y cable (at home) but no reason I couldn't run the same thing in my car with a car charger.

I use a fiio e7 on USB and it works perfectly on cm or carbon, no extra apps or kernel required. By the way, otg works fine with Franco kernel on either Rom and hotswapping is supported. I have not yet found another rom that supports it, but I have been using just carbon for quite a while now.

Some car head decks support android USB then it would charge and do audio. Just make sure it's android compatible.
Good, then we shall fight in the shade!

Well i can tell u most of those android compatible r meant can be connect n read as a mass storage,but not as ios.
Unless someone can make a custom rom like the one for 2012 model.
Has anyone tried USB audio on 4.4 yet? I recall reading they were making some changes to USB devices (may of just been mounting drives though).

Still no USB-OTG in kitkat

When u guys saying otg works dor aosp or some kernel ,does that mean it works with an otg y cable aswell? Like reading files from flash n keep it charge while with flash drive on?
Sorry for the thread jack op.
U and i r on the same boat,i am doing a car mount too.
I am doing a 4g lte one.
I don't have a car, I have a scooter.
Problem fixed !
So it sounds like if I have the stock rom, with the elemental X, I can do USB audio? Do I need some kind of audio manager to specify where to send the output, or would the USB dac automatically disable the on-board headphone jack?
tried PAC rom 4.3 with elemental X 1.8
no go for the DAC audio.
sound is mute no matter what i do.

I bought the HifiMeDIY DAC and am using stock 4.4.2 w/ Elemental X Kernal. I don't get any sound out of the dac. What did you have to do to enable the USB sound instead of built-in speakers?
The Nexus 7 is way better than you described it.
You have lots of options for car audio, and they all have downsides, but just to name a few:
Bluetooth (if your car has a bluetooth receiver)
Auxiliary input (if your car has one)
Slimport (you'd need an hdmi-audio converter, but it would sound great)
Wi-Fi direct (not very common for cars, though)

Bluetooth (if your car has a bluetooth receiver) - I need the bluethooth to connect to other things, like an odb adapter and so on. Edit: The bluethooth connection doesnt always connect automatic whit the cars headunit either so that's another problem.
Auxiliary input (if your car has one) - The aux output aint that great, not good enough for my 3500$ audio system in my car.
Slimport (you'd need an hdmi-audio converter, but it would sound great) - Yes the problem is that I need to convert the audio to analoge. It needs a converter and it still doesnt give my headunit digital audio.
Wi-Fi direct (not very common for cars, though)- I use wifi to get my cars 4g connection to the Nexus 7
So in my case. This is just a really expensive angry birds game (Without sound)!

Compatible USB DAC/Amp?

Hi, I've found that the headphone output of this phone, while good for some headphones, has too much noise for sensitive IEMs and not enough power for some less efficient headphones, so I'm looking into a portable DAC/Amp. I tried this one with a USB-C adapter:
https://smile.amazon.com/gp/product/B00FJSEAZ4
But it didn't work. I know the USB-C adapter works, as I've used it with a thumb drive, and I know the DAC works on other Android devices, but apparently compatibility isn't universal. So has anyone successfully tried a portable DAC with this phone?
My Fiio Q1 works fine with the phone.

Thanks, that's good to hear. I was considering one of Fiio's products
I tried this one: http://hifimediy.com/android-dac
Works very well together with an USB B to C converter that supports USB OTG and drove even my good old 600 Ohm AKG K 141 loud enough!
It has a Sabre DAC. Bought it out of concern that the sound of the phone might not be good enough. But it is - at least with low impedance headphones like my Ultimate Ears UE 10 TF I don't find a difference to the 180 $ sony walkman of my GF.
(Small remark: Used a Samsung USB B to C converter first. This one, while doing very well on the PC and with ADB and also with the charger did not work as OTG adaptor.)

Weird, that's the exact one I tried that didn't work. Maybe I needed a different USB-C OTG adapter

For sure. It works for me without problems - plug and play.
I use this adaptor: http://www.delock.com/produkte/G_65678/merkmale.html
Side note: While I could use the Samsung adaptor for charging (but not for OTG devices) this one works well for OTG - but not for charging.
Edit: The price for te DAC on the amazon side is way higher than if you buy directly from the Hifimediy website.
And you should also note, that this DAC while it's pretty good for higher impedance phones did not work well with my low (32 ohm) impedance IEM's. But for those I found no need to use the DAC.
I ended up with a Fiio E18, I like the fact that it has playback control, plus B&H has it on sale right now. It doesn't seem to work with Poweramp, but it works perfectly with USB Audio Player PRO.

Will USB Audio Player read OTG storage?
Most file explorers do not see mnt/media_rw/0EB0-0FF. Do any players?
Quick, and hopefully not too stupid, question, do I need to root the phone to get the DAC working with Google Play Music?

Anybody know if I could use the OTG function to get a stereo 3.5mm mic port on the G3, or on android at all for that matter?
I don't think anyone will know, but you know.. Maybe some of you have an idea. I know about USB audio recorder, but that is for audio interfaces not specifically a USB OTG to 3.5mm stereo mic in port.
