[Q] Note 8.0 MHL Audio problem

So I sold my Nexus 7, for the 8.0, for the MHL capability because I have the AppRadio2 and want to output the video onto the screen and audio to the car speakers. The only problem is that it doesn't seem like the 8.0 outputs audio through the mhl cable. I've tried multiple cables multiple external displays... The works. But can't seem to get audio to an external device. I've also tried an audio output app and that didn't work either. Any information is helpful. Thanks in advance guys

Wait...So are you getting video only, and no audio, or nothing at all???
Did you check the Android settings under "Accessories" for audio output options when docked or when other accessories are attached?
BTW, are you using the ARliberator App?
First of all, I don't think that the Note 8.0 is on Pioneer's list of approved/confirmed devices for use on the AppRadio2.
Also, the MHL/HDMI adapter that is sold in Pioneer's "Android Connection Kit" is the older 5-pin micro-USB connector.
You tried it with Samsung's newer 11-pin microUSB/MHL-to-HDMI adapter that is made for the SGS3 and Note2, right??? And you are plugging in the adapter to a microUSB charger, right? It will not work without this.
Pioneer's and Samsung's adapter for the SGS2 and original Note 5.3" will not work because it is the older 5-pin microUSB/MHL connector. You can buy the Samsung 5-pin to 11-pin MHL adapter for about $10 that should allow the older MHL/HDMI adapter to work:

I don't know why you'd want to use the smaller and lower Res AppRadio2's screen over the Note 8.0's anyway?!? I guess you lose AM/FM tuner and the Backup Camera if you have one.
You can bypass the AppRadio2 and just use your Tablet to get RCA line level preouts and Digital Optical (Toslink) audio from the Note 8.0 if you use the MHL adapter with this $40 device:

Oh, but I forgot to mention that you would need separate car audio amplifiers to power your speakers for this setup to work. :/
I just returned my AppRadio2 and am using my SGN2 with this adapter in my car audio system to get digital audio output sent from my Note 2 to the digital optical input of my RF 3Sixty.3 DSP, then to my amplifiers and then speakers.
I'm using my Note 2 because I wanted to use just one audio source/device, that also has cell phone capability. The AppRadio2's built-in Dialer/Phone app borked/hid my Note 2's Keypad when it forces the display into landscape mode. :/ I guess that I could have used Tasker to switch back to portrait when the dialer/phone app opened, but then it is tiny on the AppRadio2's display. The International GT-N7100 SGN2 also has a hardware FM Tuner, or I use TuneIn Radio to stream almost any AM/FM station worldwide.
My car also came with a handsfree Bluetooth setup that worked much better than the AppRadio2.
I'm also using the Samsung SGS2 SmartDock in combination with the USB JoyCon EXR plugged into the SmartDock to keep my OEM Steering Wheel Controls and add extra functions to my SWC by long-pressing the buttons, etc. You have to program the JoyCon EXR with your PC before installing it, but it works great to control your Android's audio player functions with your SWC.
If you do get it working, you'll probably want to use the "Screen Standby #root" app to turn off the Note 8.0's screen backlight without putting it to sleep so it charges up faster. You must be rooted to use this app, however.

I am using ARLiberator, and in terms of compatibility its not an issue considering I'm using the MHL and not the Pioneer "Android Kit". I think it is an issue with the device itself because I tried other cables and other displays and it just doesnt seem to be able to output audio through the MHL

So you ARE getting video out, just no audio?
Hmmm...weird. You are using the 11-pin MHL adapter though, right? The "Android Connection Kit" uses a "MHL" adapter, too, and it is actually better than the Samsung original, but it is 5-pin, and won't work with newer devices. So I just wanted to be sure you are using the 11-pin MHL adapter made for the Galaxy S3/4 and Note 2?
Also, maybe check that the audio output settings are set to "Stereo" (2 Channel), and not to "5.1 Surround"? IDK?
Have you done the new firmware updates on the Note 8.0 yet? There is a thread here about it.

This is probably a dumb question, but you have checked the volume level on the note once connected, right?
I just setup an HDMI connection on my unit and didn't get audio at first. Turns out that it doesn't send line level audio over HDMI. It creates a new mixer item that is muted by default on the note side.
Once I adjusted that, everything worked fine. Best of luck.

I couldnt figure it out, so after all was said and done, I just factory reset it, and now it works. Although it was kind of a pain, it turned out ok in the end

Bummer you had to resort to a factory reset, but glad it's working for you now! Rock on.

I'm not sure if this is a HDCP issue or a implementation issue but that's likely the way it is.
On my Galaxy S3, last time I tried it, I think you could have audio over Bluetooth or jack while doing HDMI/MHL video out. But it's been quite a while since I've had the cable. (It's perfectly fine on the SII X/Hercules as I had my fiancee try it before I got myself the wireless adapter.)
Under the Miracast (AllShare Cast) stuff, you are only able to direct audio through the dongle and thus need an adaptor that can split off the audio from the HDMI somehow, assuming those support the necessary HDCP crap.

USB audio

(How) Is it possible to get audio from USB on GIO?
Using CM7.2 based rom.

Any update by anyone? I too have an USB headset with microphone. I plugged my OTG USB to my Galaxy Note2 and plugged my headset. Tried played an audio and no sound coming in headset. Any idea how to get this running?

There is no OTG support on Gio i think.
Also the needed drivers needs to be implemented in Rom and Kernel

[Q] USB Audio..

Hello guys!
I've just bought a Nexus 7 to integrate in my car dashboard. Actually I didnt had so much knowledge about it before I bought it, (I only wanted the best and I hate apple so) but I didnt thought it was junk. And that's the only thing I wanted, a non junk tablet that could play music and works as a navigator without hardware-buttons.
My old stupid Iphone 4s worked perfectly for playing and streaming sound from spotify trough a regular usb cable to my headunit, so I didnt even reflect that googles new flagship wouldnt be able to do this simple task. But it seems like it doesnt work..
I've searched for answeres but the only thing I can find is to buy a usb DAC that converts the digital audio to analog audio but then I lose the whole damn point. I want digital audio in to my headunit. And my stupid old Iphone do it great, why the **** can't google flagship do it? Feels like I have bought a extra thin rock from the stone-age.
Please tell me I'm wrong and this is possible somehow. Otherwise I gotta throw this stupid f***** sh*t tablet in the garbage as fast as ******* possibly..
Sorry for my rage.. I just feel so fooled.. I've just bought a 400$ angry birds game. :silly:

You have a couple of options:
1. Use headphone output jack from your Nexus. Hopefully your car audio headunit has an auxiliary input.
2. Bluetooth! This is what I use in my car. If your car audio headunit has bluetooth built-in, then you don't need any cables at all. Just pair your car audio to your Nexus and start playing music! If your car stereo does not have bluetooth, then you need to purchase a bluetooth car kit. These connect to an auxiliary input on your car stereo (just like #1 above). There are bluetooth kits that also stream through an FM modulator, but that should be used as a last resort as sound quality suffers materially.
I installed an Alpine bluetooth car kit and integrated it with my factory car stereo system in a 2005 Honda Accord. Since I did not get the factory CD Changer option, I had that one input open to use with the Alpine Bluetooth. I'd post a link to my YouTube video showing this, but I'm now allowed to post links yet since I'm new to this forum.
The two options listed above are the only ones I'm aware of. I'd love to hear from others if there are other options. The only drawback to both options is that you use the DAC built in the Nexus, you don't get to pass through to a better quality external DAC. The only way around that is a Slimport adapter which uses HDMI. I don't know of any car audio units that have HDMI inputs.

What you want is achievable. Nexus 7 2012 works best with Timur Kernel however Nexus 7 2013 with an AOSP build or stock with Elemental X kernel can have a USB DAC with an OTG Y cable that will simultaneously charge.
If you have Cyanogenmod you may need glitch kernel which does the same thing.
I have a HiFiMeDIY DAC and OTG Y cable (at home) but no reason I couldn't run the same thing in my car with a car charger.

I use a fiio e7 on USB and it works perfectly on cm or carbon, no extra apps or kernel required. By the way, otg works fine with Franco kernel on either Rom and hotswapping is supported. I have not yet found another rom that supports it, but I have been using just carbon for quite a while now.

Some car head decks support android USB then it would charge and do audio. Just make sure it's android compatible.
Good, then we shall fight in the shade!

Well i can tell u most of those android compatible r meant can be connect n read as a mass storage,but not as ios.
Unless someone can make a custom rom like the one for 2012 model.

Has anyone tried USB audio on 4.4 yet? I recall reading they were making some changes to USB devices (may of just been mounting drives though).
I

Still no USB-OTG in kitkat

When u guys saying otg works dor aosp or some kernel ,does that mean it works with an otg y cable aswell? Like reading files from flash n keep it charge while with flash drive on?
Sorry for the thread jack op.
U and i r on the same boat,i am doing a car mount too.
I am doing a 4g lte one.

I don't have a car, I have a scooter.
Problem fixed !

So it sounds like if I have the stock rom, with the elemental X, I can do USB audio? Do I need some kind of audio manager to specify where to send the output, or would the USB dac automatically disable the on-board headphone jack?

tried PAC rom 4.3 with elemental X 1.8
no go for the DAC audio.
sound is mute no matter what i do.

I bought the HifiMeDIY DAC and am using stock 4.4.2 w/ Elemental X Kernal. I don't get any sound out of the dac. What did you have to do to enable the USB sound instead of built-in speakers?

The Nexus 7 is way better than you described it.
You have lots of options for car audio, and they all have downsides, but just to name a few:
Bluetooth (if your car has a bluetooth receiver)
Auxiliary input (if your car has one)
Slimport (you'd need an hdmi-audio converter, but it would sound great)
Wi-Fi direct (not very common for cars, though)

Bluetooth (if your car has a bluetooth receiver) - I need the bluethooth to connect to other things, like an odb adapter and so on. Edit: The bluethooth connection doesnt always connect automatic whit the cars headunit either so that's another problem.
Auxiliary input (if your car has one) - The aux output aint that great, not good enough for my 3500$ audio system in my car.
Slimport (you'd need an hdmi-audio converter, but it would sound great) - Yes the problem is that I need to convert the audio to analoge. It needs a converter and it still doesnt give my headunit digital audio.
Wi-Fi direct (not very common for cars, though)- I use wifi to get my cars 4g connection to the Nexus 7
So in my case. This is just a really expensive angry birds game (Without sound)!

[Q] USB Audio Out?

Can anyone who owns the G3 confirm that USB Audio Out (over an OTG cable) works through a DAC? I can't seem to find any information that confirms or discounts that this works.
Thanks!

It does work with my Fiio E17. Just tried it today after almost buying an app that was supposed to do so. My only complaint is that the DAC seems to be charging while connected to the G3.

Thanks, Jesadac! That's great news... I was hoping this was the case, as I believe the G2 also supported it.
I assume you're referring to the USB Audio Player Pro app? It truly doesn't replace the native ability to have a clean digital audio out signal for all sounds out of the phone.

I have the Fiio E18 and a friend has the VZW G3. We just tested the combo and it seems to work fine.

Just bought the new Cayin C5 DAC/Amp. My TMo LG G3 does not put audio out though the amp when connected via OTG. It registers it's connected I'm guessing because all audio is no longer played through the phone. Plugged into my friends Note 4 and it worked right away. Is this is G3 problem? We're both on Lollipop.

I know this is an old thread... but do I still need USB Audio Player Pro to get USB DAC to work? I thought Android 5.0+ brings USB audio, and right now my Beyerdynamic A100 doesn't work by "simply" plugging it in... however I do get about half second of audio and quits.

I go on LG G3 with app USB Audio Player PRO and HibyMusic app, my DAC is Hegel HD2 and DragonFly RED. Logitech USB headphones works too. with China OTG cable.

I can confirm Spotify and youtube doesn't play audio through usb (android 5.1.1), and it still mutes integrated speaker when connected:silly:. Must have usb-player i guess.

Using a USB dac with the Samsung A70

Has anyone managed to get a USB dac working without using UAP pro?
I have a Hidizs S3 that works perfectly through UAP pro, unfortunately my current music streaming service (Amazon music HD) isn't supported by UAP.
If I use the dac without going through UAP it is just used as a dumb extension cable and the dac isn't used.
Many thanks for any suggestions.

I tried, but sound quality is just not good without UAP.
I am rooted with Viper4Android

Thanks, stupidly I upgraded to this phone thinking it would be a step up in sound quality. It wasn't. So I bought a USB dac. That doesn't work properly ?
