Will a combination of an MHL cable, and a mini displayport/HDMI adaptor enable me to use the note with an iMac at work, with audio supported as well?
I've got a pc at home which is fine, but would like to connect up the Note at work.
This mini displayport/HDMI adaptor is said to work with audio, but I'm not sure if phone audio will be supported:

Thanks in advance for the help!!
Phone audio output is not routed to the MHL port. The "Keystrokes" as you dial the number are but not the audio of the call.
When the MHL cable is attached, the internal cameras are also disabled so you cannot use a the HDMI output to display the image seen by either camera and also prevents the use of a large screen for video calls/conferencing.
I daresay this is more a limitation of Gingerbread than the phone itself. It will be interesting to see if there is more flexibility in ICS.
Nope. I've had it working with CyanogenMod 7 on my LG. It's possible in Gingerbread, perhaps it's Samsung's software that's at fault. As for sound, I have no comment, as I haven't tested it.

I'm using the livedock and connecting the device to the screen with the HDMI cable.
But I got a problem, if the HDMI cable is connected to the phone the audio is connected to the screen also.
So I can't hear anything from the 3.5mm input. Can I somehow disable the HDMI sound and hear from the 3.5mm?
please
yea this used to be my issue as well. maybe a future firmware will enable the sound be selected to out to the 3.5mm jack instead of going with HDMI.
I would like to build an Android car infotainment device to replace all my gadgets inside the car. One option would be a micro PC with USB touchscreen and a lot of devices connected via USB. The other one would be an Android gadget, either small tablet or TV box.
The biggest question I have is: what Android devices support 5.1 audio? This is a must, though I actually can use only 4 channels. What audio formats are supported for this?
The other question would be TMC - the FM kind, not online.
Are there any embedded platforms out there (except PC and Android) which support multi-channel audio?
Has anyone done this before? I might be reinventing the wheel.
No updates? Either nobody knows about Android 5.1 sound output or they are working under NDAs.
Are you planning on keeping a headunit to control volume, do you want am/fm radio, etc....
without a headunit you will need an amp where you can use the headphone to rca adapter and usually its the amp that would add front and rear to the left/right output of your android device so you would still get the 4 chan output effect. to go for the 5.1 chan you will need another device that actually controls the 5 speakers plus the subwoofer which might be tricky but I'm sure its not impossible.
the setup I was going to go with was a amp that I can mount its power controls (left right front back and volume) (or amp/eq combo) to where I can reach it and build a mount for a 7in (possibly diff size not sure depends on how it will look) and use the heaphone to rca adapter to power the audio and put the usb inside the dash possibly with a little hub if they make it (that way not only is it getting power from it, if it allows, the addition of say a thumb drive with added music/movies. some tablets/phones have fm radios built in as long as something is plugged into the headphone jack (my new phone doesn't seem to have it but thats a feature I will be looking for in a tablet)
4chan amp
eq that would allow 2 chan in and 4 chan out plus sub out (if you have a separate sub amp)
I just want to know if there are any android devices that are able to stream 5.1, I can take it from there. Same question about TMC support.
Some details:
My car is already fitted from the factory with 4 channel preamp and 12 speakers including subwoofer low-pass. It has low-level input for those channels, worst case I would buy a preamp.
FM is pretty much given on most Android devices, probably excluding some tablets, but I won't actually miss it if it's not there.
TMC would be nice since all Androids usually have a GPS sensor and sometimes compass.
Anyway, it was mostly a request for suggestions or even a rant - I'm surprised that something like this doesn't exist yet. With the exception of dedicated units going >$$$-$$$$, an alternative set-up would be a medium-range blueray player coupled with an Android tablet. Music control could be set up with DLNA, bluetooth streaming or mixing player and android audio would be a bit harder but not impossible.
hey friends
this is a nice thought and you are absolutely great.
this is wonderful thread

Hi,
Currently I'm also thinking about installing an android tablet in my car to have music, navigation, movie player, speed camera warning, etc. But the biggest problem is the sound. I want to connect tablet with car audio using jack-jack cable. Everything is fine till the AUX source is selected in car audio device, but when I switch it to Tuner or CD - the sound from tablet is cutted off, so e.g. navigation announcement are not heard.
Any suggestions for this issue?
audio rom
its a shame that there are many many roms but none fur special purposes like this.
we need a car rom

Only solution can see is to run the audio from the tablet alone. I.e. use the tablet to provide both radio tuner AND navigation. You will end up using the car system purely as an amplifier.

This would be what I would do in this situation. Or just unplug the audio cable from the tablet when using other radio options so the navigation will come through the tablet's speakers.
I want to do something similar but rather than purchase a new device I want to use my Note2. No head unit at all. The Note2 would likely be dedicated to this use and I'd get a different phone to use as, well, a phone.
For sound I was hoping I could use USB OTG to connect a USB sound card with 5.1 output but I'm not sure if this would work. I want to use the sound card instead of audio direct out of the headphone jack because that reduces my connected cables to just one (easier) and should provide at least 4 channel output which eliminates the need for another device to control volume, fader, and balance.
For radio I was going to use SDR for AM/FM (and more) via a cheap USB TV tuner.
http://sdrtouch.com/
Where I'm stuck now is that I'd like to be able to connect an iProduct (iPhone/iPod) like you can to most car radios and control/stream music from the iProduct, via the Android Note2 using USB OTG again. I cannot find how to do this but the Parrot Asteroid Smart runs Android and it seems to be able to do it so it must be possible.
http://www.parrot.com/usa/products/asteroid-range/parrot-asteroid-smart/
Any info anyone can provide regarding the sound card and iPod integration would be highly appreciated.
You can go wireless and use some AirPlay receiver for Android.
I don't know about wired solutions, the classic iPod connector has ~30 pins and some of them are used for audio and some of them are used for serial-like playlist control plus current track information.

It's just a USB to iPod cable that they use for everything else... Parrot Asteroid Smart that I linked to has it as do most modern stock head units.
Did a little more googling and it seems several companies sell android head units that support iPod.
Why don't you use a USB DAC? There are a few out there that are surround sound capable.
Out from the DAC into an eq preamp and out to your existing amplifier. The eq preamp has main volume controls as well as sub control with dedicated output.
Also there are head units out there that are just "receivers" capable of accepting a digital inputs and outputting 5.1 signal via RCA.
I installed a nexus 7 2013 in my VW, currently using Bluetooth to connect to a receiver where it the outputs to an rca input on my deck that was relocated to my glovebox. I am planning on replacing the Bluetooth adaptor with a USB DAC in order to achieve a higher quality sound.
I am currently doing a similar install in a 2010 charger, a deck will not be used however as I will be using the DAC method with an eq and output to the factory amp. I considered going the android TV box route as I have a MINIX box, but there is some work involved in getting the touchscreen to function properly as it is not set up for this out of the box.
You can purchase a double din deck from eBay (I stumbled across it a few days ago but didn't write the link down) it has a dual os system. It uses android for the car audio function and windows for the car PC function. Not sure how well it works but it got reasonable reviews.
Edit: ...and once again I answer without reading the whole thread...:silly:
Is it somehow easier to get all the various apps on the phone to output audio to a DAC than a USB sound card?

I believe when the device detects a DAC (must use an otg cable BTW) it automatically re routes all audio out the USB. You can disable automatic USB audio routing in developer settings.

That sounds easier. Thanks for the tip.
Well I can't find any information regarding the iPod integration and I've found next to nothing for DVD video and audio CD playback and radio and backup camera functionality would also take some mucking about so it looks like I'd probably be better off buying something like this:
http://www.ebay.com/itm/7-Android-4...621?pt=LH_DefaultDomain_0&hash=item2a31320af5
Which has it all sorted out already. So much for that fun idea. No idea what apps they use for all that stuff.

That unit looks slow at only dual-core. It will probably be sluggish when multi-tasking.
The main chip probably supports several I2S devices (aux in/adc, tuner/adc, DVD) and routing plus demuxing is done via linux hardware control.
The DVD player and tuner probably support the i2c or spi protocol to control seeking and other functions. This is again controllable via the linux devices.
Usually the consumer devices don't have these easily exposed and it's probably a non-trivial task to piggyback on existing hardware, assuming the needed connections are broken out on the board. As far as I can see the only Android devices with CD or DVD are the car players like above.
Another option would be to take the sound from the HDMI signal. A DVD player/tuner can be wired in parallel with an HDMI switcher. However controlling the tracks would not be easy, it would require emulating the remote with an IR transmitter.
Can someone make kernel or tell me how to do this, maybe thru some kind of converter or something like that?
1080p/24Hz is chopy for games so maybe this can be done by software or hardware fix??
There is similar kernel but for One S so I belive this can be done for note 2.
Pls help this is realy big issue for mhl/tv output and i didnt find any solution on web how to make this happen on note 2.
I'm to having same issue.
Choppy with the dock. My GNex works so smoothly compared and it's half the phone although it is rooted.
I'd be very excited to known if a custom kernel can fix this. I've posted something similar already in this thread.
Cheers guys.

I hope for the fix to, it a shame that this isnt implemented like and option in stock software. One again please devs or anybody help us with this problem :crying:
Going to try to fix this thru vga pc because in my tv manual says I can select resolution myself thru this input (RGB PC only).
Maybe you too can do something with this.
Well i cant post links so this is what I will test with my Note2:
RED Galaxy S3 SIII i9300 i9308 MHL Micro USB 11pin to HDTV HDMI
HDMI Female to Female F/F Coupler Extender Adapter Connector
Gold HDTV HDMI to VGA HD15 3 RCA Adapter Cable 5ft
When tested will report here... still hoping for kernel modification of some kind...
I have a N7100 and a smart dock this has been my experience:
HDMI -> DVI adapter plugged into a Dell U2312HM via DVI (HDCP compliant):
- Stuck at 720x480 resolution no matter what.
- When mouse and external display is connected there is a drop in frame rate. However, if the mouse OR the external display are connected seperately the FPS remains high.
HDMI cable to my 26" Westinghouse 1080P TV (HDCP compliant but constantly has handshaking issues):
- Appears to display at 1080p or at least scaled up 720p though I set my TV in 1:1 and there are no black bars so I suspect 1080p.
- When mouse and external display is connected there is a drop in frame rate. However, if the mouse OR the external display are connected seperately the FPS remains high.
It seems that there is a bug in the code that has to do with when the phone enters that "desktop mode." There also seems to be a bug when using an adapter for some reason as well. The N7100 seems to act completely differently than my PS3. My PS3 connects wonderfully using the same adapter and the same Dell monitor, no handshaking issues. Though my PS3 to get sound out of the TV's speakers I have to mute and then unmute the TV to get sound anytime the HDMI link is closed and then reopened (starting a game for example). While it seems the N7100 behaves oppositely.
Update on my Gold HDTV HDMI to VGA HD15 3 RCA Adapter Cable 5ft combination is not working the device dont check connection thru hdmi rgb input (no signal or notification of connection). So I belive only hdmi input/output works with note 2. Once again pls help us regarding this option to lock device on 720p output thru hdmi.
man i really need this force 720p playback option as well...
My N7 is being used as a car headunit. I'm having a usb audio issue with multiple devices. With an OTG y cable, I am running an easycap and a UCA 202 w/an amped mic into the inputs. Everything works fine before the easycap is powered. When I swtich intro reverse, video shows up fine. When I shift out of reverse and the easycap powers off, all audio will only play from the internal speakers and I get "Can't open microphone". I have to either reset or dis/reconnect the otg y cable to fix the problem.
I am able to preserve usb audio out if I use the "easycap viewer" app but I cannot get the mic to work at all with the easycap unpowered after the first connection. Mic and audio work fine up until the easycap is powered on for the first time. Interestingly, the Mic will only work when I am in reverse. I figured this out while parked and testing--not really reasonable to shift into reverse on the highway to make a voice command .
Is there a flashable fix? An app? Any workaround?
Appreciate the help. Thanks.

Hi,
My receiver has no hdmi, so I have audio put to it from tv. Sometimes I would like to listen to internet radio without having tv on, so direct connection to receiver would be great, even analog one. Do I need USB audio card or there are some other options? If yes, anyone uses something worth mentioning? Anyone tried USB cards on Shield?

I use an external USB dac. Works out of the box and mutes the hdmi sound output too so you will not be able to have it connected all the time for when you want the hdmi to output sound.

That's worse, but maybe I can live with it, maybe I find one with power switch, thanks
I am using a HDMI video / audio splitter. Works well.
Best part it doesn't need to be powered separately.
Does audio go through hdmi and separately? Analog audio or digital? Or maybe can you post name of the splitter?
I have mine setup to do this through bluetooth, where with a combination of apps i simply press and hold 2 on my third party remote, and my shield connects to my bluetooth a2dp reciever which in turn is connected to my stereo speakers, i simply disconnect the bluetooth connection when i want the sound to go through the tv......which i had setup through tasker to disconnect when i long press 2 again, but i think i broke this messing around with this particular task .....that reminds me, i gotta get round to fixing this
I can do this without even having to turn the tv on or even having bluetooth on, as the remote is a RF 2.4gh/IR remote
To take it a step further, i could potentially create a scenario where i press or long press my chosen button and have the shield wake up > unlock display > turn on bluetooth > connect to a2dp > open media app > emulate media play.......and have my music playing without having to turn on the tv.......the remote having media control and volume control as standard........assuming the app supports the media standards i.e. youtube app doesnt
Apps used
Xposed
Xposed additions (can map the remote/mouse/keyboard buttons to something else or have it initiate chosen tasker task i.e. long press 2 initiates "speakers on" task)
Tasker + plugins
Anyway, thats another avenue
I will buy this converter www.goo.gl/VqOvFB

that's what i've been using since my Chromecast to send audio to my speaker bar. I just swapped the hdmi when i got the Shield.
has anyone managed to get 5.1 audio out of the shield via USB soundcard? I bought one but it seems that its sampling down to a stereo sound. I have set in settings 5.1 sound for USB.
I also bought a 7.1 xonar u7 usb dac but no output on surround channel only in left and right. I aready set the USB to 5.1 surround and tried all the video applications. Maybe the shield only supports usb pass through and PSM stereo.

USB Auidio Works with class compilant devices only, but not entirely sure what that means in this case.
What apps did you try and what audio/video source files did you used for your tests?

Same problem here, any progress since September?
im currently using this: https://www.amazon.co.uk/LiNKFOR-Ex...8-1-spons&keywords=hdmi+audio+extractor&psc=1
I connect the toslink to my sound bar so i can chromecast my spotify from my google home and not have to have the tv on. the audio still passes through to the tv, there also is a 3.5mm jack you can switch to.
I use the Audioquest Dragonfly DAC and it sounds amazing. I combine it with the Jitterbug. It's a little pricey (90-100) but I'm running to studio monitors so it's easier to tell the difference in quality.
