Irig HD-A guitar interface not working - Galaxy Note 4 Q&A, Help & Troubleshooting

Hi all,
I was really happy to learn that low latency audio devices are now available for Android (Samsung Note4 and Edge at the moment).
But unfortunately it does not work with my Note 4. It crashes the Amplitube app or cannot initialize the USB audio driver. Or else I will see the USB audio has been connected but no input or output movement on the meters.
In SoundCamp, I get the additional toast message that "SAPA is not working". I have even factory reset my Note 4 but still can't get it going.
Does anyone one know about SAPA and how to diagnose it or repair it?
IK multimedia asked me to go to Samsung for a solution which I don't think is realistic so I'm quite a bit unhappy with this situation.
Does anyone here have a working iRig going or sh3d some light on the SAPA error message?

I know we had answered this on our forum but I thought it would be good to reiterate here:
Please note that our team did have the following input on this issue:
We have been discussing the following with Samsung for some time now:
We have recently discovered that on some Note 4 devices the Samsung Professional Audio (SAPA) library crashes if a SAPA enabled application like AmpliTube is started with any USB device connected.
If the USB device is connected AFTER the SAPA application is started, everything will work correctly.
Samsung is working to release a fix to SAPA to address this problem, so in the meantime you can bypass the problem by disconnecting the iRig HD-A, running any SAPA enabled application and connecting iRig HD-A again.
Please note that if you do not disconnect iRig HD-A before running the SAPA enabled application and receive the SAPA error the only way to return to normal operation is to restart the device.
It is probably better to perform a restart before trying the suggestion above anyway so that you start from a clean environment.
This is a problem with the underlying SAPA library (it is not an issue with IK Multimedia hardware or software).

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

Issue connecting to YoCam device (wifi issue?) with 6P, other android devices connect

So my YoCam camera arrived, and excited to receive my new kickstarter toy, I tried to connect it to my phone following the basic instructions.
Phone sees and connects to the device via wireless, but the app refuses to connect. However using other android phones will allow me to connect to the camera, using exactly the same process., so it does not appear at least at a basic level, an android or an app issue.
Just wondering if anyone has any suggestions, or can suggest some troubleshooting tools so i can get a better view of what is going on.
Thanks
Hi, Not that this helps: I have exactly the same but on a Samsung Note 3 running cyanogenmod 6.0.1. When connecting to my Samsung tab S2 with standard Android no problem.
Are you running a alternative rom on your phone or standard?
Edit: see also Faq at getyocam.com

Samsung S7 mirrorlink support Appradio 4

Hope someone could help me with this. I have been using an iPhone for the last 5 years and in such I have a Pioneer Appradio 4. I am trying to see if I could make the android jump and purchase a S7 edge.
My Appradio supports mirrorlink as well as Appradio live which is garbage.
What I have been reading is there is no Mhl / hdmi support on an s7. However mirrorlink is available on the phone. Is anyone able to confirm that the S7 will connect via mirrorlink on my Appradio? I have been looking everywhere for an answer but most of the stuff is for the older galaxy phones. Sorry if I'm a bit ignorant to searching android stuff I've been chained to iOS and CarPlay for too long.
*Side question-- with Miracast do you lose all connectivity to cell data?
Thanks for all the help in advance
If your Pioneer Carplay head unit supports also Android Auto you can use this method for connecting.
Miracast doesn't interfere with the phone running data connections (wifi or mobile).
Unfortunately it doesn't support android auto. Which is pretty lame.
I dont't know about your head unit, but generally Mirrorlink should work also with the Samsung S7 Edge.
Thanks for the info now my only question is will it work with ARunchained reloaded once this is set I'll be ordering my Galaxy and getting off this iOS nonsense

For that app to work it's required to root the Galaxy S7Edge.
Anyway, if you're not used with Galaxy rooting, Knox and related possible Samsung warranty limitations, you can find these information on the forum. Moreover, to be able to root you need to buy the Exynos version, not the Qualcomm 820.

Okay good I found it on the website it has the exynos processor. Once it's rooted and I change everything I should be able to run this app then? I messaged Area51 hopefully he will message back regarding it. Thanks again for all the info and help.

Yes it works
I can confirm you that Galaxy S7 works with mirrorlink and the AppRadio 4. The sound and video quality are simply perfect. I have been using MHL before with Sony Xperia and ARU, mirrorlink is better. The only issues are the restrictions that mirrorlink implements in the navigation, no recent apps none slide notifications, etc. Hope some friend could mod "Samsung Mirriorlink.app" to break freee these limitations but also in the current situation i recomend you to use mirrorlink with Galaxuy S7 because as I said, the stability and quality are just perfect.
appradio 4 mirror link
did u have to disable android auto?

so it will only work with rooting your s7 edge? if so how do I root my s7 edge? I to want to use mirrorlink with the sph-da120
I Just installed the SPH-120 and I can only get my Galaxy s7 to connect to blue tooth. Tried the developer mode with USB debugging, Switched to MTP configurations, and both USB ports along with multiple APPS. and I cannot get it to connect.
When I connect to the second USB port, Both the phone and radio attempt to connect but the phone screen shuts off and the radio says incompatible USB (original cable).
Hi how do you connect wich cables you use to get it working like you say?

I just created an account here so I can add a reply in case anyone struggles to get MirrorLink to work. I got an SPH-DA120 to work with my Samsung S7 Edge. I went through the same process of connecting the phone, seeing the connected message on the phone screen, and then the SPH-DA120 screen says "Incompatible USB." I thought it was an error but it was simply my failure to understand MirrorLink. You have to first get a certified MirrorLink app on your phone and then choose the home button (or whatever it is...looks like a Windows 7 start menu) and your certified MirrorLink apps will show up there. When you choose the USB/Ipod2 source the HU will always say "Incompatible USB." In my case I used RockScout, which then gives you access to everything on the phone by selecting a "Choose Source" option--that mirrors your phone's screen and provides a gateway to everything on your phone.
Maybe this process is common knowledge about MirrorLink but I spent way too much time googling this and trying random things to get the phone to connect. Something else worth noting is you need a high quality USB cable. The HU seems fine with USB extensions (even cheap ones) but it requires a high quality cable to connect to the phone. Some work, some don't. Not even all Samsung cables work.
One more thing...I actually contacted Pioneer's customer support to get assistance with this. To my surprise they replied to my initial email within an hour. That's impressive for customer support at a large company like that. Admittedly I figured out that the USB cable was the problem shortly after I sent the email but the quick response from them was nice.
Can somebody confirm if a non rooted Galaxy S7 can MirrorLink using rockscout while in motion using the 7000nex soft touch bypass? Trying to mirror every app and function while in motion using the nex. This includes YouTube, Google maps, chrome etc
Great information here. I just started driving a Jeep with appradio 4 in it . I have a galaxy s8 plus. Any advice what to do?
Still stuck with my note 8. Stock android Mirrorlink works but very limited. I tried with rockscout, button savior, LG mirrordrive app etc to screen mirror my phone but n way. The only fault is with Messenger pop-up showing nicely on my car screen. So I tried rooting my phone with magisk and hide my root but the Mirrorlink app is not working anymore. When connected to my phone it says authentification not valid... and the database is no more the same when I want to add some apps in pkgnames...
Hi,
I have problem with mirrorlink pioneer sph-da110 with galaxy s7 edge when I connet via usb I see mirrorlink in appradio. I click in mirrorlink then I see Lg Mirrordrive an I choose this after that I have dark screen and nothing else happens. Somebody can help my where is problem?

Unable to use external DAC with S8+

I have no issue getting my Chord Mojo working with the UAPP app on my S8+ but when I try to use band camp, youtube or any other apps it will not route audio to the DAC properly. Note that UAPP uses a proprietary driver for routing data to the extetnal DAC. A notification comes up when connection Mojo to S8+ via micro usb-usb c otg cable(see screenshot below)
I have tried every option in the normal settinsg and developer mode but no matter what it just reverts back to "charge connected device". I have played around with all the USB settings in Developed mode;
Prevent automatic usb routing
Setting the usb device to audio source,
/MTP
Etc
Nothing works.
I even uninstalled UAPP, attached Mojo and opened band camp, still nothing. Worse yet, often it will freeze with Mojo connected and then restart itself or get stuck on the carrier boot screen during restart.
Seems that Android system is not allowing the device to connect properly although I can't be sure. I just want to be able to send all my audio to my exceptional Chord Mojo. Bummer because everything worked fine on S7 Edge running Android 7.0 when I selected MTP under developer options. Unless there's a fix I'll only be able to use Mojo with UAPP.
You should probably post over in the correct forum
Samsung Galaxy S8+
https://forum.xda-developers.com/galaxy-s8+
You have a Galaxy S8 Plus, not a Galaxy S8. That forum is dedicated to same device you have, and while the S8/S8+ are almost identical (in software), more people will be there to help you.
Done.

MXQ PRO 4K TV BOX - No remote and No Display

Hi I need some help please , I recieved the tv box from a friend with no remote. I plug in adaptor as well as usb to pc to power it up. There is blue light on tv box but no display on hdmi or av input. Any suggestions on how to switch it on or what to do.
It may be possible to control it using a usb keyboard and mouse if you could see the picture and it has the correct drivers. The picture thing sounds like the biggest problem, I would suggest trying different HDMI cables and tv settings. This is highly unlikely, but if by any chance your friend turned on usb debugging before the picture stopped working, there is a tool called scrcpy that can be used with adb that allows you to view your screen on your computer. It’s quite possible that the thing has broken itself, there’s a lot of reviews online about Android TV boxes spontaneously breaking after only a few months of use, sometimes less than that.
