USB sound card works on A500 but poorly so far

I ran Usb Audio Tester root (free) from the Play Store on my Ionian A500 running Civato’s Flexreaper extreme and v6 bootloader . Plugged in my Logitech G35 usb headset and after fiddling with the controls managed to get sound and mike working on the headset. Alas the sound was very poor and the mike was always on . Also the speakers and mike on the tablet were active also. maybe a different usb sound card would work better with this program. At least it shows the tablet is capable of outputing USB sound.
I will keep digging for program or controls to make this work

Yeah me too

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

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

can you please do me a favor (im asking because not connecting to tv avoids extra electricity costs, since android can be controlled trough airdroid)
connecting the HDMI cable only to ug007ii and leave the other side hanging loose without connecting to TV
does it 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

Dragonfly Black USB DAC

Since updating to Android 7.0 my USB DAC no longer works. It was working fine on 6.0.1.
Looking inside /system/etc audio_policy.conf no longer exists and there are two new files, audio_policy_configuration.xml and usb_audio_policy_configuration.xml
Has anyone got their DAC working on Nougat via USB-OTG?
Working now.
Got a test version of the app which wasn't working and it's all good now. USB Audio Player Pro support is top notch

Hi, Does the Dragonfly work without USB Audio Player Pro with things like Google music and other third party apps? If it does is the volume severely limited like it is on Marshmellow?
Edit: In Marshmellow native support worked only when UAPP was disabled. Otherwise the app would launch and it's drivers would initialize the device blocking it from other apps.

A wonderful device
Pros: Compactness, sound quality, no need to charge
Cons: Could not found any
This is really a must buy for an iPhone owner who likes to listen high quality music on iPhone. I am using it with my iPhone 7 Plus and the sound quality it improves will surely blow your mind. I know it is not that good like Chord Mojo and I am also owner of Mojo too but on the go it is very hard to manage it when DF Black will give you full flexibility because of it's compactness and it is really very pocket friendly in terms of pricing. Go for it.
I also uploaded a small unboxing video on youtube. You can watch it by searching my channel name on youtube: DreamTravellerIndia
Thanks...

USB-C audio in 9.0 update

Hello y'all,
I recently discovered by accident that when I tried plugging in my PS4 controller through the USB-C port the phone was showing headphones icon in the status bar. And sure enough, the audio wasn't coming from the phone. So can anyone test this out since I don't have any USB-C headphones, but I always wanted them.
Thanks to anyone participating in this test.
Write your results here.

Audio through USB-C works at least since Android 8.1. I've USB-C mini DAC (Hidizs Sonata HD) and works perfectly. Also I tested Nobsound NS-10g USB input via USB host adapter and also works. So, isn't a new feature of 9.0 update, if you are thinking so.

I've been using fulla schiit 2, usb audio works on 8.1

Actually yes, I was thinking it's new because when I tried my friends USB C headphones it didn't respond.
But thank you for clarifying me! Your response is appreciated.

Does your Hidizs Sonata work also with Android Pie? I've just got Sonata II and it works only if I connect it within one minute after reboot. After that the phone ignores it and acts like nothing has been connected (but the phone is powering the dongle as I see increased draw in logcat and hear a very faint click in the headphones). So if I want to listen via Sonata, I must connect it first and reboot the phone, then it works perfectly. I tried all the available firmwares for Sonata, it does the same with all of them. With the PC or Huawei phone it works whenever I connect the dongle, so it most probably isn't faulty USB DAC, but rather something in the phone. Also I'm missing the option "Audio source" in the USB options in the phone's settings completely, if it makes any difference/sense.

Yes, my unit works perfectly with Android Pie, stock and custom ROM. What build are you using? Maybe something is corrupt

I'm no stock Android Pie, tried the adapter with February patch. Unfortunately adapter just stopped working with all of my devices (got really hot and then died completely), so can't verify with March update.
I'm going to visit an Apple store and try their USB-C - 3.5mm adapter, it is being said to be of a very high quality and is just 10USD/EUR and available locally, so I don't have to wait more than a month for delivery of another Hidizs from China.

Apple dongle behaves the same. Working when connected within ~1 minute after reboot, won't work on later (re)connection. I tried a different kernel to no avail. Would love to know why is it happening.
Edit: it happens that I'm forgetful, see explanation below

Oh my.. I'm stupid guys, I totally forgot that I configured recommended workaround "disable USB host" for 70000.USB wakelock couple of months ago. It was running one minute after boot via Tasker, no wonders I was experiencing this. Dongle works completely fine now (except of volume buttons on the Apple DAC). Sorry for stupid confusion.

Will USB DAC work plug and play on Android Q ?

I just bought a USB DAC and i spent last few days to find a workaround for it to work on android Pie, because the "Audio source" option is gone for god knows why. I was going to downgrade to Oreo but all of the link for the Oreo Custom Rom is already disabled by devs.
Luckily i found a way to make it work but only with my music player, it still doesn't make a sound on other app. And it have some serious problem with the volume too, so I'm stil trying to look for alternative.
Does anyone tried using a USB DAC on android Q ? Does it work plug and play ? 'cos I've confirmed the "Audio source" option is still missing in android Q. I just want to use this darn thing man.
