[Q] Audio Through USB

I'm currently aching to be able to play my own music through my car speakers, weird place for this yes.. if it's the wrong section to post this please let me know.
But, I was wondering if it's at all possible to feed the phone's audio through the USB.
For example, I have a USB port on my stero in my car, and when I plug it in..i'm able to feed off my SD card to play the music thats on it. But.. I'd like to be able to play pandora as well..which I'm currently unable to do.
Was wondering if this is possible. If i've confused you feel free to ask more questions

Since it isn't possible.. what about an app that allows me to control the music played? I can stream music from the sd, but its got to mount to read therefore I don't have access to the stock music app. Only way to control what's played is the buttons on the stero and its pain staking..

I don't believe this is possible. As far as I know, when you use the usb the deck itself is decoding the mp3's (or whatever music files you're using) directly. It doesn't support playing music through the usb, it just uses the usb to get the files. I hope that makes sense...

So is that why I ca never plat music on my xbox whenever I have a phone hookedup to charge? I thought my xbox just didn't play nice with phones

So your car stereo has a USB input but no auxiliary? If so, your best bet would probably be to get an FM transmitter. Like the poster above said, your car's stereo is merely mounting your phone as a mass storage device and reading the mp3 files off the SD card and decoding and playing them locally.

It sees it as you do on the computer, just a drive. The only way to get what you want is to use a source from the phone that plays audio. Head phone jack or Blue Tooth. Your stereo... if it has USB should also have an AUX input or BT. Havn't come across to many that have USB and not an AUX or BT. Its nice though... having Pandora in the car.
If you tell me the Model of the Stereo I can help you out. I have seen a BT to FM Mod. Those are kinda cool. If your in a pinch with a stock stereo.

Makes sense. My stero does have an auxiliary port on it, but due to recent events I'm really short on cash lol, was wondering if there was a work around so I'm not limited to my sd for music.
Since it isn't possible.. what about an app that allows me to control the music played? I can stream music from the sd, but its got to mount to read therefore I don't have access to the stock music app. Only way to control what's played is the buttons on the stero and its pain staking..

Nope... The phone isn't even connecting to your stereo. When you put it into USB mode so it can read the SD, it unmounted from the phone. Its as if you pulled the SD out and slid it into a card reader. When you pull the plug... It will remount to the phone. You'll notice it scanning for media at the top.
Now when you go BT... You can control it via the stereo or phone, using the Aux you can control it by the phone. "They" could make the phone controllable via USB like an Iphone but they would have to built that into the stereo like they do the Iphones/Ipods. Not likely to happen unless the Galaxy S takes off like IPOD did.

In theory, a rooted Epic with proper kernel support and hacked cable (since they don't exist commercially) can repurpose the data pins on its USB port for left and right analog audio thanks to the Fairchild FSA9480 USB switching chip inside the phone (the same chip enables the USB pins to be repurposed as a serial port with nonstandard voltage levels, enables the normally-unused fifth pin to be used as mic input, enables it to be used with a special "JIG" interface for JTAG reflashing without having to hand-solder anything to the microscopic internal pads, and apparently can also work its magic in conjunction with a chip by Silicon Imaging to use 5 pins to output a signal that can be transformed by a companion chip (embedded in the cable's connector shell) into valid HDCP-compliant HDMI. I'm pretty sure the 9480 can also repurpose the two data pins for external I2C, but don't quote me on it.
Check out the I9000 boards... they're about 2 months ahead of us. If you google for FSA9480, you can find a brief (but revealing) dialogue between a Samsung engineer and the Kernel.org folks regarding a kernel addition to support the chip. He had a few issues, because on one hand he's apparently not allowed to say much about how the chip works or what it does, but the kernel folks managed to wring much of it out of him one juicy detail at a time. If you check Fairchild's site, they don't even acknowledge that the chip EXISTS, but it's been photographed inside all the Galaxy S phones in various teardowns.
In English -- yes, the hardware exists today to connect your phone to a stereo's analog inputs via a cable that repurposes the USB port... but the official software to make it work from Samsung and Sprint doesn't exist, and the information needed to make it work ourselves on a rooted Epic with AOSP isn't quite available yet.
I'm personally quite happy about the uart, because that means we DO have an easy, low-ceremony way to do i/o between something like a gamepad built into a hardcase a-la-iphone-GameBone that doesn't require Bluetooth (note that if something IS using the USB port for UART purposes, the USB port is still active, but the phone sees it as having nothing connected because the signals from the D+ and D- pins are physically re-routed by the 9480 to the CPU's UART pins. Think of the 9480 as being like an old-fashioned telephone panel with cables that can be moved around to connect the USB port's 5 physical pins to different pins inside the phone.
I'm now pretty sure that this is why there are exactly 7 contacts on the microUSB connector inside the phone -- 5 are used to get the pre-HDMI signals out of the phone, and the other 2 (3, if you count the ground/anchor tabs and assume they carry a signal as well in addition to mechanically anchoring it in place) are used to supply +5v and ground, and possibly one wire for half-duplex signaling purposes.

Wow that was a lot of info... lol. I didn't know that about the usb tho. That's good to know. I was thinking of taking it apart to see.
But... I think he's wanting a UI via the USB like the way some players will do for the IPODs, not analog. To go throught all that when the Head Phone jack will do the same... I could only see that if it was broken or if you really really want only one cord to the phone.

I've got an Alpine unit, I hook my USB up - turn on the TUNER. Mount the Drive and once the phone is done - swap back over to USB and i can get all my MP3S. sadly I get all of my ringtones too - odd when the radio is full blast and a track changes - none the less works well for me. Try it.

I purchased this Kensington LiquidAUX Bluetooth Car Kit for my phone a few days ago. It works perfectly on my sister's iPod touch (no AVRCP [silly apple]) and an old WinMo 6.1 phone.
I just got my Epic in the mail today so I'll be testing it out soon.

WTF. AVRCP (bluetooth remote control) is really buggy with this phone. I used the LiquidAUX with an old Omnia for a week with no problems. The Epic connects and plays audio just fine. I can also pause and play music but the forward and back buttons don't work. When I first pair the phone with the device everything is fine, but after disconnecting and reconnecting the remote control stops working. I got it to work after un-paring and re-pairing but it only worked once.
The Moment I had before this had really choppy audio.
EDIT: I had the phone opened up in DDMS and the phone is receiving signals from the remote. But it only reacts to them when the media player is on the screen. Weird.

[Q] How to connect to car audio system via USB?

I wanted to know how to connect via USB to my cars audio system.
I used this tutorial: http://www.mobiletechworld.com/2010/11/18/use-your-windows-phone-7-device-as-a-portable-usb-drive/
I can now store and retrieve picture files from the phone but I still cannot play music files on my cars audio system. It seems as if the phone turns off this feature when my cars head unit tries to communicate with it via USB.
I also cannot connect via bluetooth.
I have read that some folks have been successful in implementing this feat. I really dont want to use the headphone jack because I cannot control the phones audio via my head unit. I guess I am looking to set it up legacy style like my previous phones eg iphone, nexus one, milestone etc.
Any advice would be greatly appreciated.

The portable USB 'trick' doesn't make the device a USB Mass Storage device. It's a client-side registry modification that only makes the device viewable in windows explorer (legacy mode). It's still running its communications over the proprietary MTPz zune-sync protocol. This is why after running the registry modification, you can't just plug your WP7 into another computer and have it pop up, and also why it requires the Zune software to be installed, and to sync up first for it to work.
This is also why it won't/can't work with your USB capable audio system. It has absolutely no ability to do Zune protocol sync (as far as I'm aware, Kenwood made a head unit that could, but I don't know if it works with WP7. I'd doubt it), and despite the misreporting of various sites, your WP7 is not magically now a mass storage device.
Bluetooth may or may not work. I don't know about A2DP support on either your car's head unit, or WP7, and it may be specific to the device/manufacturer as to whether this is present (I have no idea). If bluetooth doesn't work, you're pretty much **** out of luck.
Headphone jack is your best (only) option. I can't recall if the supplied headphone cable has inline media controls. If so, you could probably macguyver that into a line-in cable for your stereo and use the media controls on that. Ghetto, but workable.

wow, that really sucks.. I am liking this phone less and less...

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

Car Install - Mitsi EVO 9

Hi Guys,
Recently put the finishing touches to my Nexus 7 install so thought i'd share some pics.
Im running 5.0.2 lollipop and Timur Kernel, with the following attached;

Audio Volume is controlled with this - http://www.amazon.co.uk/gp/product/B00RM75NL0?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00
Power supply is from a 2amp (5v) cigarette usb socket, which is wired up behind the dash and not using the original cigarette socket in centre console.
I installed the amp under the passenger seat and run all the cabling under the carpet and out, where needed, behind the facia panel, the dac is also situated there and i ran the usb hub into the glovebox. You literally cannot see any wiring bar in the glovebox as i wanted to maintain a stock look throughout the car as best i could, everything is also revertable back to stock if the need ever arises, the only thing i had to do was screw the amp into the carpet under the seat, but the small holes left would never be seen anyway.
The facia panel was designed and made by a lad named reece who runs http://www.rtafabrication.com/ - top bloke and did an amazing job and the finish and quality of the panel is top notch. I went for a wired dash panel but he can also do wireless panels too!!! - if your thinking of a car install contact him to see if he can design a facia panel for your vehicle.
android apps i use
poweramp,
sat nav is navfree
video is archos Kodi.
As you can see, also for fun have a megadrive emulator with ps4 pad to play games lol. Also can use either torque pro or OBDlink II for my OBD Link LX bluetooth OBD port reader. (http://www.amazon.co.uk/gp/product/B00H9S71LW?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00)
Had an alpine before which was a great piece of kit, but nothing compared to this.

In terms of Timur ROM reliability, its great and had no issues worth mentioning so far

Im thinking of buying his rom when i can afford it. But i have it in my car without a usb otg. So the rom is not fully functional to what it can do once i get around to get a usb otg.

I have never used Elemental X but my understanding of using Timur over any other Kernel was that it uses his own Powerevent Manager app which can do things like wake up when power is applied and deep sleep when power is removed, something i believe Tasker can do. Also not sure if Elexmental X allows simultanious USB hosting and charging + Fast Charging. Supports certain Rear Camera's. Automount of upto 4 FAT32 drives, custom boot animation and shutdown video's, block wakeup alarms. People using other kernel may tell me otherwise but this is what i came up with when researching which to go for.

Just a question to be sure I understood everything.
Without USB Hub, you plug the OTG cable to the tablet and USB DAC to the USB port. Then the USB DAC is connected to the amp using RCA correct?
Currently my setup is not using a DAC (rca to jack directly connected to the amp) and I have interferences because of that so I'm thinking about using a DAC. Is it natively managed by Android?
Thanks,

Yep that is pretty much it, OTG cable then USB DAC straight into USB port, and connect it to your amp / stereo via Red & White RCA jacks, or as i did - - - - - Nexus 7 - OTG cable - USB Hub (4 port) - USB DAC - AMP
I believe Lollipop handles USB audio natively, anything before needs a kernel to implement it - again if anyone knows different then please let me know

Is audio taken from usb? I didn't think any Android can send audio from the usb? Or is that why I need the OTG-cable?

That looks amazing, stock even, imagine having Andoid auto on there.
Any pics of the evo?

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.

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.
