USB Audio out?

So does our SGSII line up have this feature? the only thing i can find close to this is a mod. http://forum.xda-developers.com/showthread.php?t=1321491
I see in the settings there's a Dock setting but Ive also read that we don't have this feature.. Im abit confused. Could someone clear this up for me?

I don't think so, I sure wish it did. That is one of the things I liked about my iPhone was that in my 2011 Chevy Truck I could plug my phone into the USB port and listen to anything playing i.e. Pandora, iTunes, etc. I tried this with my EPGT and just got an error on my truck stereo.

I looked into this a lil while back...the only way I read some peoples' phones outputting sound to their stereos was by actually mounting the device (like with a computer). Unfortunately the mounting option doesn't pop up when I plug it into my pioneer avh-p5200bt...so I just have to use my iPod...sorry
Only option is through aux as far as I can see. I hope the sga3 can solve this somehow lol

Did you put it in disk mode and use it like a thumb drive?
In my camaro, if i plug my phone into the USB port and select disk drive, it uses it just like a thumb drive.

I did not, let me try that next time I am out and about. I also thought about turning on the audio through the dock, maybe that will do something also. Thanks for the reply about it.

(Q)USB audio Out is it possible?

I recently bought a new stereo for my car that has USB,Aux inputs.. i can use the aux but the sound is not as good as the USB. i can use the USB however i will be limited to the stereo controls and it,s pain in the a$$.
can i play music over USB cable so i will have full control of what i wanna play. ?
to make it easy when u mount your sd card on your computer you cant access their content from the phone same think with the stereo
it,s a long shot but you never know there might be a mod that i messed

Hmmm i don't think you can, you're stereo is probably "iPhone ready" where you can use the iPhone physically i think... But with Androids it'll see it as a storage device.
If i were you... Go Bluetooth, i find the clarity better than aux too. That's if you can return the stereo and invest a little more for Bluetooth.

I don't know if you can use a USB cord or not but I know you can use an auxiliary cable. That's what I do

You can, it depends on what your system can handle.
At work I plug into Home theaters via USB
Even though their crappy for audio fidelity, samsungs stuff is the most compatible.
But flac wont be found on any HTIB on screen menu I have tested

It may benefit you to know that your phone has preset volumes when you hook up different devices. I'd say try to use the AUX cable if you haven't invested in a Bluetooth device (which is the better option). Just turn the volume up in the media settings and you should be good to go.

Car Stereos with USB

Does anyone have a car stereo with a USB port? If so can you elaborate on what that is like to use? I am purchasing a new unit and that feature is one I do not truly understand. A few questions I have are listed below, but feel free to add anything else you think might be useful in making this decision.
1: Does the phone charge while connected to a USB port on a stereo?
2: Can you use the file system and player controls through your stereo or do you have to control the music and other audio through the phone itself?
3: Does the audio work from all sources with a USB connection(for example phone calls or turn by turn), or will it only play music player audio?
4: If you do have access to the file system from your stereo, will it display song titles and artist info etc? How cumbersome is it do control this way?

It would be helpful to know what actual head unit you're getting. But I will try to answer most of the questions as best I can since I have a fairly new Pioneer HU.
1. Yes, but it only charges on "USB" mode, not "AC".
2. Yes and no. The Pioneer HU that I have does NOT support MTP mode (which is what Jelly Bean, and I believe ICS) uses. Basically MTP is the protocol for storage on the Galaxy Nexus. If you can find a ROM or Kernel or any way to change the mode to "Mass Storage", then you'll be able to browse the file system.
3. Only music (or whatever else is inside your MP3 file). When you connect to your HU through USB, your phone basically turns into a flash drive. From there you have to navigate to your "Music" folder and tell it what to play. The only way to do calls, navigation and music at the same time is to use Bluetooth or a 3.5mm cable with an inline mic.
4. It displays what is inside your ID3 tag inside the MP3 file. So basically, if you have all the info filled in, then yes, it will display it. As far as how cumbersome it is, it takes some getting used to, but not to bad (on Pioneer, I have no idea on any other brand).
Short answer: Unless your stereo support MTP or you can find a way to force "Mass Storage" (which I'm not familiar with a way how), your stereo will only charge your phone. It sucks, but that's the way it is.

Pioneer has the app radio which will control your phone and also allows you to use Pandora on the actual H/U. That said I have never used it nor do I plan on it as its a dual din and I am just happy using bluetooth.

I have a JVC unit that works great with my nexus running linaro aokp jelly bean. The unit is x50bt. It will not play through USB only charge. However it is Bluetooth enabled so it can play anything including you phone calls through your car stereo. I have it setup so that my phone auto connects and plays Pandora automatically. The head unit displays song title and artist and also allows u to thumb up or down using the remote conyrol. I also have playlists set up in power amp for my MP3s. The built in equalizer in power amp along with the equalizer in the head unit work well together. I have the USB cable in the rear USB port so it is hidden in my CRZ. The tiny Bluetooth adapter is in the front and does not look out of place.

Per your suggestion, I purchased the X50BT. I am not disappointed. As you said, it does not support MTP, however I have a tiny 32gb Flash Drive(about the size of the Bluetooth Dongle) inserted in the front and the audio quality is simply breathtaking. I have my phone set to auto-connect via Bluetooth, which it does seamlessly. It even connects for audio however the BT audio stream sounds terrible when compared to the USB audio from the flash drive. I don't know if that's a limitation of my phone, the technology or the unit but it hardly matters since I can fit all of my music on the USB drive anyway. I just have to use Bluetooth or the 3.5mm jack for Pandora. Thanks for the suggestion, I really love this head unit!

If you're rooted, you have to tweak the Bluetooth sound profile using voodoo or DSP manager for example (which one your kernel allows).
You could add some "gain" amp or reduce the "Mids" and raise the "Bass"..
I have a different sound presets for the:
-Phone speaker (added some mids)
-Headphones (optimized for my Sony headset)
-Blueooth (lots of bass and "Rock" setting, sound is pretty good)

I just wanted to point out that even if you found a way to force USB Mass Storage, it is unlikely that your radio would be able to read the filesystem. Most radios will only read FAT file systems, while the Nexus uses EXT3 (I think, could be 4). So Bluetooth/AUX are really your only options.

I just installed an Alpine HU, It is also does not support MTP. I really like using the Bluetooth but have found that I have to reboot my Gnex and or restart my car to get the Bluetooth to sync correctly. USB does charge but it is slow. One thing to look for is Bluetooth Parrot.

I am finding that it is more of how my HU looks at my blue tooth. Thus restart car. I am wondering if it has something to do with Android BT. My gnex has worked this way with multiple roms and BT enabled HU.

I bought a cheap stereo from Wal-Mart a Dual stereo with Bluetooth, takes a SD card, front and back inputs and satellite compatible. It has the USB plug that charges but like the others, doesn't read the memory on the phone. I stream through Bluetooth all of the time with Spotify. My son's Galaxy SIII can connect too if I turn mine off without changing anything. It was a great investment. It is a convertible and the microphone works great at 70mph with the top down. For $118 I am very happy.

I don't believe the Galaxy Nexus will work with the USB of many head units since the Nexus uses MTP instead of UMS.
Hopefully someone can come up with a UMS for the Nexus.

I think the better way would for HU to be able to connect like they do to Apple products and have MTP support.

HU
I know that JVC / Ken-wood have apps for android. Looked more like a HU controller rather then playing from android. Never tested.

I think I figured why my USB isn't connecting from the AVH 4000 NEX to my galaxy note 3 SM-N900. It's possibly due to the MTP mode. I believe if the was a mass storage mode that will work, kinda like a USB stick. I don't think the firmware in my HU is properly picking up MTP, all it does is charge the phone. You need a kennel that has UMS enable for mass storage however the international note 3 SM-N900 currently does not have such kernels. There is only 3.... To my surprise. Maybe the last time I ever go with international models again. If anyone finds away around this let me know thanks.

My car does not have USB or card reader, but aux line!.
So I decided to go cheap and buy a Vieta FM Car Transmitter and BT Handsfree unit, and I does a decent job.
Perhaps in a future I'll go for a Parrot...

[Q] USB / Bluetooth Keyboard ends up as Player 1

Hey All,
I've contacted OUYA support (and have a dialog going with them) about this, but thought I'd throw a line out here as well.
I've got a bluetooth Microsoft Entertainment Keyboard 7000 as well as a USB Logitech K400 keyboard.
Both work pretty well with the OUYA (though I don't use both simultaneously for obvious reasons).
One thing I've noticed, however, is that no matter what order I pair the OUYA controllers and keyboard (or connect the USB keyboard) in, the keyboard ends up being player 1 after a period of time.
Example:
Pair OUYA controller 1
Pair OUYA controller 2
Connect USB keyboard
After a day or so, and possibly a full power cycle of the device, the keyboard ends up being Player 1.
This doesn't pose an issue for the most part (the OUYA controllers display that they are players 2 and 3), but some games specifically rely on the device that is identified as Player 1 to actually be an OUYA controller in the game, and therefore I have to go through a whole rigamarole of unpairing all controllers / keyboards, disconnecting the USB keyboard, and doing a full shutdown of the device, then powering it back on and waiting for the pairing wizard to pop up so I can re-pair my controllers.
The real question here is, has anyone else experienced this, and if so have you found a viable workaround?
I'd prefer that the keyboard (whether USB or bluetooth) doesn't get detected as a controller period, but simply acts as an auxiliary means of input for fields where I need to type something in, move a mouse, etc.
Thanks!
pitcherj

Yes, I have exactly the same issue with a Logitech K400 as well. Very annoying, I haven't found a workaround yet.
I have an Ouya controller, a PS3 controller and the K400 in that order and after a while the K400 takes over controller position 1.
There needs to be some way of locking controller 1, or at least a way to quickly change controller positions from within the interface without needing to repair everything.

I had the exact same problem, after looking around for several days trying to find a way to get my controllers paired to slot 1&2. Installed the Blue Board app from the OUYA market.
I've been installed it on my phone, got to to to pair, and used it a couple of times. After that I noticed that my controllers properly paired to slot 1 & 2, and if I hook up my keyboard it properly goes into a different slot.
Blasted from my Samsung Galaxy SIII (CM10.1 Masta Mix).

Over here it is the same problem.
I use a Rapoo E2700 Keyboard with touchpad. It is connected via a seperate USB wireless-dongle.
[A little o.t. but i want to tell everybody thant the keyboard is working great! The Touchpad is super smooth and (unlike the Ouya Controller Touchpad) realy good to navigate a mouse cursor]
It would be nice if there was a menue where you could assign wich Device takes wich controller-slot. Working without a keypboard is a little annoying to me.

Same for all my keyboards, i think it might be intentional.

Everytime I plug in my keyboard dongle it causes the system to lock up and i have to restart, but if I boot with the keyboard hooked up its player 1. They need to get this fixed
Edit: It seems that removing my hub and pluging straight into the ouya works... but now I've no way to use xbox controllers...

After reading through this thread, I'm beginning to wonder if it has something to do with using keyboards meant for PC. The reason I say this is I have had my Motorola Bluetooth Keyboard made for the Xoom paired since the day i got it and it never took over any controller port, but 1 full power cycle with my Logitech USB keyboard and it took over 1st controller.
Does anyone else have a android BT keyboard they can try?

Xbox wireless dongle as well as a el'cheapo GE USB keyboard do the exact same thing... very very annoying

I think this is tied to USB taking priority over Bluetooth. Every USB HID I plug in ends up becoming player one.

Are you using a powered USB hub? My non powered USB hub does the same thing.
If a powered hub doesn't do it, it might have something to do with the power draw on that single port.

I think its more just because The USB connects on boot, while the bluetooth controllers and keyboards have to be turned on. Since the USB where already there they get the first spot and the rest get whats there when they connect.

USB Audio Streaming

Hey everyone,
Has anyone here tried to do any kind of USB Audio Streaming with the Razer Phone? By this I mean using a USB-C to USB-A cable to play music (and other audio) from the phone to another device. Specifically, I have a GROM box in my car (2004 Acura TL) that previously allowed my Nexus 6p to play music to my factory stereo while still keeping the steering wheel controls working as well as showing track information on the factory head unit. Using the same GROM with Razer Phone however has not worked. The car and the GROM box do not recognize that the Razer is plugged in. But it will always recognizes the Nexus. So now I'm wondering if the Razer even supports USB Audio Streaming or if the only way to get sound off the phone is to use the dongle to connect to a headphone jack. Any help would be greatly appreciated.
Thanks,
Steve
