[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...

USB Mic and Bluetooth Mic

Hey guys, new to the Rooting community, but I would first off like to thank each and every person that has put time into these projects. The possibilities that have been unlocked on different devices has been enormous and its all thanks to the dev community.
I do however have a question, I recently took my NC and installed Ginger Bread and then Ice Cream Sandwich onto it with no troubles. However upon reading everything that has to do with Bluetooth Audio Input and USB Hosting, theres something that doesn't quite add up.
I can successfully connect to my Bluetooth headset with both the built in Bluetooth and a Rocket Fish dongle that I used through USB Hosting. However I get no audio input, I know that this is a known problem and it has to do with a possible lack of audio codecs and some other ideas that I have seen thrown around.
What doesn't add up though, is that when I connect my Logitech USB Microphone using USB Hosting it works perfect and gets picked up by every app. So my question is, what is the difference between the USB built in drivers and the Bluetooth driver that was unlocked?
From my understanding the Audio input file, driver or whatever it may be sits as a separate file. So with that in mind wouldn't that mean that the file exists, because the USB Microphone is using, so why exactly doesnt the Bluetooth connection pick up the Bluetooth ear piece as a microphone and refer it to the same audio input file?
Once again this is basically me spit balling and asking some questions. I was looking through the source code for the Nook Tablet (Trying to find its internal mic driver) and noticed that there was an audio C file and was wondering if that is what is being used by the USB devices to recognize Audio Input.
Anyways, any response would be great, one of the last tweaks that I would love to help get worked out as I planned on making myself a lovely Voice Control app to run on my Nook Color, and a Huge USB headset is rather illogical.

Since you're apparently asking a question about a Nook Tablet, not a Nook Color, you should probably redirect it to that forum.

Audio on Linux and therefore Android is a huge can of worms that even most developers can't figure out. Bluetooth is yet another very difficult library and has its own way of dealing with audio in and out. A2DP media audio out protocol has no audio in capability. As far as I know, no one has ever sorted out or enabled hands-free protocol for the NC, which is what it would take to do a headset with mic.

[Q] Use Nexus Q as an external amplifier?

My Nexus Q is slowly collecting dust on my entertainment center. It looks pretty, but being limited to Google Play or YouTube content only just bites. I've already got an iOS device and a receiver that supports Airplay (which quite frankly works much more reliably), so I don't have a reason to leave it plugged in beyond the novelty of it.
What I'd love to do, however, is use for the "audiophile quality" amp it supposedly has in another room with some vintage Bose 301 speakers I have and my desktop PC. Is there any way to get audio in on this thing? It's got optical audio out, would installing CM10 allow me to change that port to optical input instead? Or how about USB, would any hack or rom allow me to plug it into my PC and use it as a USB-Audio device?

The only thing I could think of would be an app that makes it a Bluetooth audio reciever. But it doesn't appear to have one. Last I tried cm10.1 the amp didn't work. Just HDMI. You could sell it

UG007 ii - rooted, running great

I got a UG007 ii from Amazon for $50. I ordered the original version UG007 but got the one with two microUSB ports, research shows it is the UG007 ii. Very lucky to get a free upgrade, but after reading some other forums also very lucky to not get a *clone*. After reading about clones, and ordering problems, I can report complete success and happiness.
Not many thorough guides and lots of random stabs at getting rooted. Some of the downloads set off my Avira anti virus which was bad, so anything not totally clean was deleted and not used.
DRIVERS: Getting the drivers to work on Window 7 x64bit took some searching and work. I was surprised that both microUSB ports will supply power to the UG007, but only the microUSB next to the microSD slot will work for adb. Also, there is an extra USB section in the settings that allows your device to communicate (at all) with the PC. Wrapping my head around the fact the UG007 ii device defaults to supporting multiple USB host ports, it makes sense there is a switch to reverse the defaults for connecting to a PC. Twisted brain stuff. LOL.
ROOT: Many various methods exist. I found only one root method that worked, and all others I tested failed. After the drivers are working, it is very easy to root using TPSarky-VonDroid-Root.zip. I really like this method installs SuperSU, and I updated it via the market afterwards. I verified root successfully, loaded busybox and terminal emulator via the marketplace.
RECOVERY: I update.zip installed a CWM recovery successfully. The xda member fun_ has this great post for RK3066 devices. Follow the links to CWM-based Recovery images for RK3066 devices and download the UG007_CWM.zip for Ugoos UG007. Aterwards just rename to update.zip and push to /sdcard and install.
During this whole process I used a USB keyboard with small touch pad for *mouse*. The CWM recovery only works with keyboard, but I could have used only a USB mouse on drivers and root setup, because the device has an onscreen keyboard.
Overall the device works great. There are some cons:
First: There appears to be no microphone nor record ability with the stock ROM. I tried lots of bluetooth headsets which play music and movies fine but the microphones failed. I ordered and will try an external USB soundcard dongle later.
Second: There is a security problem because the screen never locks nor sleeps, with one random exception (clicking on items in notifications). The workaround for security is a wonderful application "Smart Lock Free" and its widget to lock/unlock all with one click.
Nothing else really bothers me, so I must say this device is an exciting Android Stick Computer.
Model: rk30sdk
Android version: 4.1.1
Kernel version: 3.0.8+ [email protected] #169 SMP PREEMPT Thu Dec 20 18:07:08 CST 2012
Build number: RK30_ANDROID4.1.1-SDK-v1.00.1015 rk30sdk-eng4.1.1 JRO03H eng.ant.20121220.180742 test-keys
UPDATE ONE: The device is available on Amazon and others. Search for "UG007 ii", verify 2 microUSB ports, verify Android 4.1.1, verify looks same as below:
Afunta(tm) Bluetooth Ug007 Mini Pc Android 4.1 Google Tv Dongle Dual Core Cortex A9 Wifi 1080p RAM 1gb+rom 8gb+3d (2 Micro USB Slots)
Price $56.99 USD from afunta-mall
or
New Version Bluetooth Ug007 II Mini PC Android 4.1.1 Google TV Dongle Dual Core Rockchip 3066 Cortex A9 Wifi 1080p RAM 1GB+ROM 8GB
Price $62.48 USD from geekbuying.com
The above are just two vendor examples, looks exactly like mine. There are many other good vendors. The geekbuying.com guys are interesting because on their website they released a 4.2.2 ROM for this stick. There are also many bad vendors and clones which look different and are not UG007 ii. Your mileage may vary. Good luck.
UPDATE TWO: I have now tested three USB sound cards. The only working USB soundcard, that survives a reboot still working, is the Syba SD-CM-UAUD USB Stereo Audio Adapter, C-Media Chipset, RoHS. With this USB soundcard the audio input (microphone) and output (speakers) work with the UG007 ii. See further information in next post.

I added the USB sound card. Now I am able to use a microphone on the UG007 ii. Great.
The (semi) working device is Syba SD-CM-UAUD USB Stereo Audio Adapter, C-Media Chipset, RoHS The microphone input works, audio output not.
UPDATE: Finally got audio input and output working with this device. Basically, plug and play is not always a reliable method. Instead reboot with device connected and audio in & out works.
I also got another fancy USB sound card from Syba that does not work for input nor output. This one finally worked. This one did **not** work for me. I did little troubleshooting.
UPDATE: After further testing I found this device also works, but sometimes crashes on plug and play. When I reboot with device connected the audio in & out works, and subsequent plug and play works. Typical problems are caused by plug and play device with recorder application open or music player open, or switching devices with plug and play without rebooting.
So, with a microphone connected on the first, I decided to try VOIP programs again. After installing Groove IP, same as before it crashed when launched. However, Talkatone works. It is complicated to get it working. Here is what I did:
Installed Talkatone, In the settings it gives under the *Phone* tab, I selected Call Settings. I changed Start Call on "normal". It was set to "BlueTooth (when available)", but I could never get the microphone working, listening with bluetooth headset and microphone input to the USB sound card. Bluetooth was wierd because I was able to hear on the headset with setting "Bluetooth (when available)" but neither the bluetooth nor USB sound card microphone input worked. Bluetooth devices never show in the Android Sound settings.
Under Android Settings, Sound, Sound Devices Manager. With the above USB sound card connected the options are:
Talkatone working configuration:
Sound input devices: USB PnP Sound Device (***selected)
Sound output devices:
ROCKCHIP HDMI (***selected)
USB PnP Sound Device (not selected)
Note: I switched my audio OUT setting to HDMI and connected a speaker to the back of my HDMI monitor. You, like me, are probably now saying WTF. Yes? While the microphone is working on USB PnP Sound Device it seems the audio output does not work on either of my USB sound cards. However, with Talkatone setup Start Call on normal, the HDMI audio output works with the microphone input on USB PnP Sound Device. LOL
UPDATE: If you reboot with USB sound card connected you can use USB PnP Sound Device output. But, plug-n-play may kill your output until reboot with connected.
I run tests using Music player for audio output, and the Sound Recorder for input. The Sound Recorder application can be *found* on the stick computer in the /system/app folder. It is bundled with the device but I was unable to find a launch icon. Information on Sound Recorder is Version 4.1.1-eng.ant.20121212.085830 Once run, I can subsequently find & run again using search on "SoundRecorder". Also, in the Play market the Sound Recorder Shortcut by Kayan Nurav gives an icon as a fix to launch Sound Recorder.
Using these configurations I can successfully make Talkatone voice calls with the UG007 ii. My voice quality depends on microphone sensitivity. The sound out via HDMI to speakers sounds perfect.
There are still some annoyances. After reboot or re-plugging the USB sound card: if you want Rockchip HDMI output the Android settings need to be fixed (as shown above). I frequently test sound output using the music player and test input with sound recorder because of frequent sound input and/or output failures requiring me to reboot. Definitely a work in progress, yet interesting.
UPDATE: Finally got audio input and output working with these devices. Basically, plug and play is not a good method. Instead reboot with device connected and audio in & out works. I tested a third USB sound card where audio input/microphone does *not* ever work. If you find some, please post further examples of working USB soundcards in this thread.

quick question
i want to use the stick computer as web/ftp server so i only need it on and there is no need to a TV except for the first time i use+configure
does the stick turn on and boot just by plugging the power ??

No, it does nothing with power plugged only. I must first plug HDMI and then power to get boot.

No. It does not power up when connected only to cable. But, if you turn off monitor and connect cable it does boot.
There is an old hack of putting resisters on DB15 video connectors and plugging into laptop external video ports. What this did was enable new screen resolutions on 1st generation netbook computers. It was something if done wrong could also ruin your video card. LOL
Thinking along the same lines there us surely some way to fake the HDMI monitor connection by hacking an HDMI plug.

Cant Wait
I just got the exact same unit you did I was expecting the UG007 cant wait to hook it up in the AM Thanks for all your postings it will be a great guideline for me.
Thanks Again

Thx, OP, for this thread~! It came in really handy after I purchased the UG007II and I was looking for a way to root and install CWM. I got this for mom for Mother's Day and she really loves it for watching Netflix shows & movies.

CWM for Official UGOOS 4.2.2 firmware
Has anyone else upgraded to the latest official 4.2.2 firmware? I have and it's very good. Smoother, faster, and everything still works, of course. I also got it rooted using the original method for the original Android 4.1.1 firmware.
But I'm having issues with CWM. I installed the original UG007 CWM through the Rockchip flash tool (as opposed to the update.zip method b/c it doesn't work with 4.2.2 anymore) but I can't actually create any Nandroids inside CWM. Things aren't being mounted & recognized correctly.
Does anyone know of any updated CWM recovery for 4.2.2?

i try everithing and cant connect to my pc de UG007 II
