[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.

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.

Best way to repurpose G1

I switched to a Droid X for almost 6 months now, and my G1 just sits on my shelf. What's the best way to repurpose my old G1? I have considered donating it to a good dev so they can make good use of it, but what are other options?

Some of them just use it as the backup phone. Other pass it down to their familiy members (ie: kids, etc...) I got mine from my brother as a pass me down.
Some of the others users here using it to test the new ROM for G1. (bascially becoming the tester for the ROM).

Turn it into a car music player. You'd need
-USB host drivers for the G1 (works on Android 2.2)
-mini-USB splitter/headphone adapter (it'd need a USB and headphone jack)
-AUX jack on the car radio
-3.5mm cable (goes from headphone adapter to AUX)
-mini-USB to USB cable
-powered USB hub and car adapter
-portable hard drive
Kind of a lot but you could get one heck of a music collection on a portable hard drive.

I second this
Its the best use for this thing if you dont use it, mines has been sitting on the shelf with my other old phones and hasnt been touched in months.

Hm, I not sure if both the audio adapter and the USB host drivers can work at the same time. Lots of people have done HDD mounting but nobody has tried using output at the same time.
Crap, what a time not to have my USB adapter. Maybe I can pick one up at the flea market.
Well if it does work, why stop there? Plug it into a home audio system. Find an app that allows you to control the music on the G1 from your other phone. Tada! Remote controlled 1TB stereo system. If the G1 wasn't such a weak phone you could turn it into an HTPC.

I used one of my old G1 to use as a walkie talkie. I can use the push to talk app to talk to my kids while there home on Wi-Fi.

[GUIDE] USB Gaming on Nexus S

Greetings,
The purpose of this post/thread is to describe how to use a USB gaming controller on the Nexus S, which is now possible thanks to the work of fellow XDA member sztupy. Before proceeding, I highly recommend that you read his Galaxy S thread, especially the first few posts (http://forum.xda-developers.com/showthread.php?t=1450298).
First, some demonstrations:
Using USB Host Controller app and Super Mario 64
Batman: Arkham City
Metro 2033
Dirt 3
DISCLAIMER: I take no responsibility for any damage you do to your phone.
1.) FLASH KERNEL AND DOWNLOAD APP
First things first, you will need ICS and to flash a kernel that has USB OTG support in it. At the time of this posting, some kernels with USB OTG are:
-steve.garon’s kernel (http://forum.xda-developers.com/showthread.php?t=1427352)
-mathkid95’s Matr1x kernel (http://forum.xda-developers.com/showthread.php?t=1361477)
-Ezekeel's GLaDoS kernel (http://forum.xda-developers.com/showthread.php?t=1336529)
If you do not know how to flash a kernel, please Google it. You will also need to download sztupy’s app “USB Host Controller” (https://market.android.com/details?id=hu.sztupy.android.usbhostcontroller).
2.) ACQUIRE USB CONTROLLER
Next, you will need a supported USB controller. The following should work:
-wired Xbox 360 controller
-Logitech DualAction controller
-Logitech WingMan RumblePad
-wireless Xbox 360 controller WITH wireless receiver
-wired Sony Playstation 3 controller (not yet tested)
...probably many others
3.) OTG SET UP
Thirdly, you’ll need a working USB OTG set up. Sztupy’s thread shows you a few ways of accomplishing this. Below is a (crappy) diagram of MY current working set up.
http://dl.dropbox.com/u/15806590/diagram2.png
I think this is the best set up because you don't have to buy any fancy OTG cables or USB hubs. But that's just my opinion.
In terms of the order for connecting things, I find it works best if you connect the phone LAST.
4.) FINAL STEPS
Once everything is connected, open up the “USB Host Controller” app, select the “Settings” pane, and set the Operation Mode to “Auto-host” (if you are using a set up that involves an OTG connector/cable, then you'll likely need to select OTG mode instead). If everything went right, the app will close automatically and you should be able to navigate your phone with the controller. You are now ready to game!
Just a note with the 360 controller. The middle button will always flash on and off, and will not stay lit on one quarter of the circle as on an actual Xbox. AFAIK there's no way to fix this (unless you use tape heh).

Games/Apps TESTED & WORKING: (This list is not meant to be comprehensive, and will be occasionally updated)
Note: Pretty much any app/game that supports button remapping (such as emulators) should work
Emulators
-nes.emu
-SNES 9X EX
-N64oid (the right analog stick is not functional)
-Mame4droid
-FrodoC64USB
-Mupen64Plus AE
-FPse
Native/Regular Android Games
-Shadowgun
-Grand Theft Auto 3
-Samurai II: Vengeance
-Riptide GP
-Meganoid
-Reckless Getaway
-Cordy
-EVAC HD
-Radiant HD
-Muffin Knight
Some (not all) of the Xperia Play compatible games will work too. See here for a comprehensive list of Xperia Play titles: http://forum.xda-developers.com/showthread.php?t=1217060
Other
-OnLive (!!! This means you can play the majority of onlive games that are game pad compatible)

thanks man i was thinking of a way to do this.

This is amazing !

I tested the Logitech Dual Action controller yesterday, it works also fine.

Hi! May I use your first diagram in my post too?

Sure! Be my guest.

Cool! 10 chars

nice. any idea if this works with the controllers for the original Xbox? I have a modded Duke I use on the computer, just replaced the Xbox!usb male with a regular usb male, and would love to be able to use it on my Cappy. I know it works perfectly on the mainline Linux kernel, but I'm having no luck finding how the drivers were implemented in ICS. I can't test myself just yet, still waiting for the otg cable and download mode jig to come in.

I can't say for certain, but I think it should work. I found another thread here: http://www.acertabletforum.com/forum/acer-iconia-tab-accessories/1014-what-game-controllers-work.html for the Acer Iconia tablet, and one user claims their original xbox controller works.
I suppose the only way to know for sure is to try it out yourself. Once you get your OTG set up and running, let us know how that works out for you.

Nice thread, very useful for me, I sold my wired 360 controller, and i thought i will buy a new one when i asked at sztupy's thread if the 360 controller would work with this method, he mentioned me about this thread, and i saw on the 1st page that a wireless controller would work with the receiver...luckily i have one of those but on the op says only it was not tested...so could anyone give me some info about that?

Well the reason I suspect that it will work is because I saw this video www.youtube.com/watch?v=TrTmsZIb0a8&feature=related. Since we now have OTG it is reasonable to assume this would work for us as well.
I tried looking around for a wireless receiver to test but unfortunately all stores near my area only seem to sell it with the controller.

hm...i'm gonna try it, so, i didn't understand the diagram show in the OP (from the dropbox link, i'm not too good in this), but would it work, if i use a USB Hub, connect the hub to the phone, a usb charger to the hub, and also the receiver?

Read sztupy's post here for some ways you can connect a hub: http://forum.xda-developers.com/showpost.php?p=21503413&postcount=2. As you can see, it is indeed possible to power the controller/receiver from the hub if you have things connected properly.
When you're setting up USB OTG/host for the first time, use a simple device like a USB flash/thumb drive to verify that your connections and everything else are working properly. Then you can try hooking up other peripherals like the 360 wireless receiver.
To be honest, I haven't had much luck getting USB OTG/host to work with a hub, which is why I went and created my own 'Y' cable. It really isn't that difficult to make, and it's cheaper than using a hub, provided that you have soldering equipment already.

Word of caution, the 360 controller wireless adapter draws a lot of power, i recall there being high incidences of it dropping out when plugged into PCs, so be sure to power it adequately.

woah...i really don't know anything about this electronic thing how should i do?

Just look at your charger and check the output rating. It should say something like: 5.0 V, 0.75 A. Ideally you'll want the second number to be higher (like 1 A for example).
As a point of reference, my wired 360 controller works fine on 0.7 A. But as tiuk pointed out, the wireless receiver may be more demanding.
But really I think you should be okay if you stick with the standard Samsung Nexus S charger. If you need more current for your peripheral, you can simply disable the current draw of your phone with the USB Host Controller app. This way, all of the current from the charger will be directed to the device instead of being split between the device and your phone.

[Q] Another Car Install: Questions

Hello all,
I'm sort of new to a lot of this stuff. Especially car audio.
With that said, I'm planning on mounting a nexus 7 in my truck soon, preferably this weekend. I've done a lot of research and read a lot of threads all across the internet. This is where I've decided to ask the questions that remain...
So to start off I've got a 05 Silverado 2500 with a double din stock radio.
Theoretically the nexus 7 should fit, as I've seen it in a video; in a GM vehicle with the same dash and what not.
Next, the main problem/question for me is with regards to powering it. The simplest answer I've found is
saying
Yes, ignition->relay-> 12v 3A usb converter-> usb hub -> Nexus 7/DAC/USB Storage/Joycon Steering wheel controller
Click to expand...
Click to collapse
I need to know if it truly is that simple.
I've already located what wires I want to use for the power source(a sunroof wire that's live for 10 seconds after the ignition is turned off, even though I don't have a sunroof it is still there) and I've figured out how to deal with the relay... But from there will the usb hub on work right? Initially all I plan on powering is the nexus 7 with a DAC(I've read USB is best?) and a flash drive. I don't have an amp, do I need one for a DAC to work right, it seems like everyone else has one? Again, I don't know car audio and's new ground for me.
Any help is appreciated.
Thanks guys,

Music in car through usb

Does anyone know how I would be able to play music in my car through usb? I am currently using tune link which uses Bluetooth and 3.5 jack. The issue I have, is that I have to change the song using my phone rather than the control buttons on my steering wheel. Sounds dumb, but I hate having to pick up my phone and navigate to screen to change the song.

The music out via USB was removed on the s5...was present on the s4.

Not true. There is a lot of misinformation promulgated on the subject. Music out on USB works fine on my S5 just as it did on the S4, S3, S2 and S1..
But that isn't to say that Samsung, Google or (especially) the automotive audio equipment cartel make much effort towards standardized interoperability. It's frankly a mess, a hodge podge of half ass implementations and proprietary protocols that usually don't play nicely together. It can be made to work with carefully chosen components or creative approaches. But randomly connecting components from two different vendors typically fails.
While Samsung and Google could be characterized as only having made a minimal effort to provide standardized USB support.. that is still leagues ahead of what most automotive audio vendors have done. Not to mention that it's routine to find inaccurate details, if not outright lies of what automotive component X will supposedly interconnect with. I sometimes wonder if their marketing departments even bother to collate real facts on the subject before they write their copy.
It's not too hard to find decent DACs and headphone amps that will accept USB audio out from the S5, but I frankly gave up trying to figure out what would or wouldn't work on the automotive end. I ended up going with a brute force approach and installed a SBC (miniature PC) in my car. Having a full PC as a middleman, means that there is a vast array of powerful software (and hardware) that can slice, dice and format the control stream to whatever is needed by the auto head unit. But it's hardly a simple or off the shelf solution.
The OP can probably find a working solution if he searches hard enough. The S5 has USB audio out, although making it work with some car decks requires a combination of root, custom kernels (proper USB host support) and audio apps. An app like USB Audio Player, in conjunction with a kernel that has proper USB host support will satisfy many auto decks.
Hopefully Android L will give us better USB support. But it also depends on how sane your automotive equipment vendor was when they designed your car deck too.

The problem is that since 4.1.2,USB Mass Storage was removed.
Most, if not all, radios, media players, etc don't support the MTP protocol. They require a mass storage device, and do not support a media device.
Sent from my SM-N9005 using Tapatalk 2

MTP is a newer and much more capable protocol. The problem in your example is that radio, etc vendors are stuck in the past and not adopting newer standards.
MSC (mass storage) has many serious drawbacks that are overcome by the newer transactional protocol. MTP was standardized six years ago, which is just short of forever in consumer electronics. So one has to wonder why the radio vendors continue to drag their heels and can't get with the program.
It's like blaming Android for having moved to flash memory.. and refusing to go along. Expecting everyone to continue using cassette tapes instead. Yes that would be one way to maintain compatibity. But it doesn't make a lot of objective sense.

Guys, but what about using USB analog audio input? I remember I did something like that with Galaxy S II - from 5 mini USB pins one was used to sense what phone is connecting to - for ex if it is a car dock, desk dock or... should it enable analog audio output on USB data pins.
Unfortunately I no longer have dock I made back then, anyone knows if that might work with S5?
