->[Q] Tablet with digital audio out [tablet->optical(toslink or coax)cable->DAC]
Hello,
I've tried the search and couldn't find anything relating to my issue.
I need a portable device/music player that has the ability to stream digital audio to my DAC (digital to analog converter).
I would like to listen to my music in my car using this tablet/music player. I have a DAC/Signal prosessor which has both optical coax and toslink inputs to recieve the signal so either one is fine.
Here is the signal path explained once again:
tablet -> optical toslink or coax cable -> DAC -> any given audio system (In my case also car audio system)
Please help me choose a tablet or help me find a way to do this. I know that some tablets have hdmi out, but it gets a little too tricky to seperate the digital audio signal from hdmi port to spdif, am I right?
Any help is greatly appreciated,
-Tersi

Guys, I don't mean to be impatient but I thought this was the place to get some answers to my problem.
Is there a way to send digital audio via usb port? I think there are ways to convert digital audio from usb to spdif..
Or could there maybe be a docking station, that has a digital audio output?
Please share your knowlage of the tablet world!

I am also looking for this too! I want to use a tablet as a car pc and run the audio out of it digitally to prevent all noise and ground loop headaches.

Did anyone ever get anywhere with this. I'm looking to do the exact same thing and the HDMI converter kit I bought is useless so I'm looking for another go around.

ainol novo basic
I just received an ainol novo basic w/ ICS (mcbub.com from LA). It uses a MIPS processor so not all apps are 100% compatible, however I am able to use it as intended (music player). If you tether you can use pandora, slacker, etc.
I take the HDMI out into a monoprice 5557 (sorry no url)
HDMI converter which outputs toslink, analog, RCA.
I use this in a home application (110v), however they are low power and you can use it in a car.
Be careful you need the Ainol Basic because it has the HDMI output. The paladin (which I also have) does not.
I'm sure there are others but for $130 I doubt you will do better, especially because it's running ICS also.
I use RCA optical into my Fiio DAC (sounds better). Toslink works too.
Monoprice switch uses ~3W on 5V, the Ainol is powered by miniusb.
I'm sure you have an onboard DAC (Fiio is excellent tho), but if you dont I recommend it. It has issues w/ 5.1 audio tho, so only pass it stereo.
I haven't tested 5.1 sound on it, although the specs say it will pass it. Your DAC will probably be the issue.
HTH.

Is this the only tablet that can do that? I was also considering this. Doing digital to the back of the car and then running it to a powerful car audio system.

I am also looking for this tablet or solution to this problem. Anybody knows?

usb dac optical out
I know rhis thread is old but for anyone looking for optical out via usb samsung note2 3 8 pro line s line nexus 7 both. Nexus 10. All of these tested w a behringer uca 202 dac w optical out. And I love it. Almost any newer andoid tablet that supports usb host will work.

Yep !!ok!!But the problem is (for car install) the charging (in the same time):crying::crying:
Even the older samsung tablets with the multi-pin connectors have the ability to conect and charge .
This make me mad...

What kind of tablet do you have there are otg and charging kernels for most of the popular tablets and a few tricks for any samsung that supports otg...and if ur tablet doesn't support it u can wire a relay to a moded cable that will charge when the car is off and otg when car is on.. if u need details let me know.

[Q] galaxy tab plus P6200 otg + RCA cable work?

Hi Gurus,
1 Question, I have seen many post on HDMI cables to plus & it works but I have a question on RCA cables.
I understand that those ebay & amazon selling Galaxy tab P1000 RCA cable will not work, so I have thought about this & in case someone have tried,
If i get a Samsung Galaxy Tab USB Adapter
(SAMSUNG TO FEMALE USB ADAPTER CONNECTOR GALAXY TAB ) & connect to
3-RCA to USB ADAPTER which amounts is <$10 USD
Can this work on the TV if connected.
I 'll be cool if it works, we can play movies & stuffs...
thanks!

150 viewers & 0 takers? well, i have ordered the RCA cable..once arrived..we can tell...

No it absolutely won't work. RCA is analog SD video. USB is digital data. The cables are designed for very peculiar equipment that has the ability to output video that way, not generic USB equipment. Heck, not even normal USB video cards work on Android, and this isn't even that.

have got the RCA cable for galaxy P1000...it did not work for plus..but i can open up the connector & resolder the wiring based on the 30 pin schematic..
anyone know for RCA connection..what should the pin connection be for audio & video...if it works out..then we can have RCA cable which is cheaper & hdmi still have to get a cable for hdmi itself...& frame lag ...

audio works
I have a p1000 cable with RCA video audio out and USB connection the audio and charge works great but no video.tested on 10.1, 8.9, and 7+

It's still an analog cable. Unless you can get the tablet to push an analog video signal, this won't work.

but comparing tab plus & tab 7.0, tab 7 P1000 can work with RCA cable & schematically, they look the same...so is it the software which defers the plus from working? I have ordered the hdmi dock as well, but it be glad for everyone if we can make this happens...
if the P1000 can work RCA...
P6200 should too...
I understand that in P1000 there is this TV out settings,
can this "app" be exported to tab plus...?

Just an update to the above for anyone want to know about getting the tv connection to work:
bought the desktop dock from ebay/amazon (OEM) about 25 bucks & a cheap min hdmi cable to work.
1 thing to notice though, charging cable to tab plus must be plug in to work or no signal will generate.
Also when running tv shows from plus, streaming Tv will be slower than usual when connected to TV somehow...
When disconnected, streaming is normal, when connected, streaming is slower but will still get to show on TV connection.
Also, when running certain program in portait mode, tv still show landscape even though auto-rotating is enabled (or disable), tried both ways,
so it shows that it only support landscape mode.
not sure on HDTV adapater though...only experienced with desktop dock of galaxy tab 7.0 (this work for my plus 7.0)

[Q] Is it possible to connect USB-Stick and HDMI at the same time? (eg. dock)

Hi,
often I want to sort my videos recorded by the PVR with my Tablet (ed.: Easier seek and rename)
and watch it also on my big TV via HDMI (less complicated atm then to stream it).
So I need the USB-Stick connected to it and the HDMI, too.
Is there some kind of adapter providing this with the SGN10.1 ?
Regards
Splotz

Not possible ?
ed.:
I found the pinout of the SGT10.1.
edit: Its SGT 7", but maybe the same pinout
http://forum.xda-developers.com/showthread.php?p=14612129
Looks like it could be possible to use "all" things..
Hope there will come a dock or keyboard dock to use it like a full port netbook.

Or is there already a multimedia dock available ?

Don't think so.

Something like that for the Note 10.1... wanna have...

The only thing I really liked about asus TF300 was the ability to easily connect usb hdd (even ntfs) to the dock while it was connected to TV through micro-hdmi. I set up a bluetooth keyboard and mouse and managing the tablet on the tv was a peace of cake. But I returned it because the performance sucks on TF300. I really wish there were some similar dock for the note tab too.

I think the Note can connect to the allshare cast dongle with is wireless mirroring. To basically the same thing. Or if you have a newer Samsung tv it connects wirelessly. to it as well.
Not sure if you can connect a usb hdd to the Note though through the usb connector.

Thx, thats true.
But I am looking for hardware connectors for HDMI, USB, Charging and Audio at the same time. Like a "real" Multimedia Docking Station / Cable.
Usable everywhere with HDMI TVs, etc...
(Maybe the SGN10.1 has also analog TV+Audio out as I saw some adapters for Galaxy Tab with these connectors)

Soo, it's half a year later... I'm looking for the same solution as the OP... I want to be able to connect my Note to a HDMI monitor, then have at least 2 usb ports (mouse and keyboard, third one would be nice) and be able to charge it at the same time. I'm looking online for a cable that would allow that but it seems impossible. Is there any hope for Note to be an interactive center?
There is one solution though... I could buy the wireless hdmi dongle, then bluetooth mouse and keyboard (does Note support 2 devices through BT at the same time?) and thus leave the charging port free but that's not so good option considering that I wouldn't be able to plug even USB stick through such setting. Still, that would cost a lot more than I'm willing to pay for it since I don't have BT keyboard nor mouse and the wifi gadget is too expensive if you ask me.

hdmi and usb at same time?
the diagam posted under 'build your own cables' shows all the connections on the 30 pin connector, but doesnt yet show which wires hook to an hdmi cable, or how to hook up hdmi.
further confusing is the fact that none of the labels for the pins on the samsung connector match any of the signals listed in the hdmi Wiki page.
would someone who has opened an hdmi adapter or dock please post wiring info for an hdmi hookup?
please? or perhaps high res photos of both sides of a dock connector board?

hdmi tv-out cable

wondering if anyone has used a miniusb to hdmi cable for their touchpad to play on their tv.
I'm asking because I did this on my toshiba thrive and I'm hooked now :S and want to do same with touchpad if possible
I can find some cable/adapter fairly cheap online so if it works, i'd get one
something like this http://www.amazon.com/HDMI-Female-Mini-Male-Adapter/dp/B000TYL27M since I already have a hdmi cable so no need to buy another if an adapter would work
edit: i'm also wondering because a quick search said it wasn't possible but i also see this page that lists product as working with touchpad :S http://www.uzid.com/wholesale-hp-touchpad-hdmi-micro-to-hdmi-lcd-3ft-adapter-cable-cord-link-1.html

What you are looking for is USB MHL since the Touchpad has no HDMI port only micro USB, but the Touchpad does not support this feature.

hm ok thanks , maybe i'll look into those hmdi android dongles i see in marketplace then.

The USB port on the HP Touchpad is barely USB OTG host compliant to connect USB devices, like keyboard, mouse, flash memory, etc. It is not USB HML capable, meaning there is no circuitry available to route video out the DATA+ / DATA- wires of the USB port.
There is no USB Dongle, or cable, that can do what you want. HP Touchpad does not support USB to HDMI.

I think he means to get an android tv dongle. They are little android devices with HDMI out and usb input, usually one of those 1Ghz A10 processors and 1Gb RAM. Neat little things, but my phone has MHL.

the mk802 is what you're talking about. there are a bunch of new versions comming out all the time. http://rikomagic.co.uk/forum, and http://miniand.com/forum are good places to get support and talk about these new devices.

Too bad we can't have HDMI out, Touchpad would do well as replacement for my media player

SlimPort [USB to HDMI, DVI, VGA and DisplayPort]

The exciting features of the Nexus 4 just keep on coming. It seems it will support a technology called SlimPort which allows you to use the micro USB to connect the phone to a second display via HDMI, DVI, VGA and DisplayPort.
The only connector available at present is for HDMI, which also charges the device while connected. Other connectors are to be released in the future.
Info from Engadget.
EDIT: New review from AnandTech. See below:
In my Nexus 4 review, I noted that the device was the first shipping handset to include support for SlimPort via an Analogix ANX7808 SlimPort transmitter. When I wrote that review it wasn't immediately clear what advantages SlimPort offered over MHL, which has become relatively ubiquitous in the year or so since its introduction. Since then I've acquired the SlimPort microUSB to HDMI 1.4 SP1002 and VGA (D-SUB) SP2002 adapters from Analogix for testing out SlimPort on the Nexus 4.
SlimPort is a new video output standard which works over microUSB, and is effectively an MHL alternative based on the DisplayPort standard administered by VESA. SlimPort is offered both license and royalty free, and supports up to 1080p60 or 1080p30 with 3D content over HDMI 1.4 (up to 5.4 Gbps of bandwidth), in addition to support for DVI, VGA (up to 1366x768 and 720p at 60 Hz), and DisplayPort. What's different about SlimPort from a user-facing perspective is that external microUSB power is not required for the adapter to work and is instead only required for optional charging. At the same time, the adapters draw no power from the source to operate.
I've spent some time playing around with the SP1002 HDMI adapter, which I believe is based on ANX7730, and the SP2002 VGA adapter, which is likely based on ANX9832. As of this writing, the Analogix SP1002 adapter is available on Amazon for around $30 USD. I haven't seen the SP2002 available online anywhere yet, however.
When connected to the Nexus 4, the HDMI adapter rotates the UI into landscape and mirrors the display just as expected. Resolution is scaled to 1080p60 on the Nexus 4 up from the panel resolution of 1280x768, which results in some letterboxing. As expected there's no requirement to have microUSB power connected to the adapter, I tested it with and without external microUSB power, all this does is just enable charging.
I posted a video review (shot on the Samsung Galaxy Camera) demonstrating the Nexus 4 doing mirroring with the SlimPort SP1002 adapter and received a query about whether the combo enables multichannel audio over HDMI as well. I tested VLC for Android with some .MKVs I had laying around with 5.1 AAC tracks and found that VLC will decode the multichannel audio and ship it over as 5.1 PCM to my A/V Receiver, so this does work, surprisingly enough. There's no bitstreaming support as far as I can tell, however. As an aside I was able to playback a number of 720p MKVs with hardware decoding checked in VLC for Android and 5.1 audio out with no dropped frames. The Nexus 4 seems to be a passable platform if you're looking to play the occasional 720p video over HDMI — provided you have the free storage for it.
I also tested out the SP2002 microUSB SlimPort to VGA adapter, which has a longer cable and correspondingly beefier module for accommodating the D-SUB connector on the end. I tried with a Dell G2410 LCD display and XGA resolution DLP projector and saw an output resolution of VGA (640x480 at 60 Hz), which wasn't quite what I expected. The SP2002 should work just fine with 720p60 over VGA, and I know both monitors expose the proper EDID, it seems as though the Nexus 4 just defaults to this mode. Just like the HDMI adapter there's a microUSB port on the back for optional charging, though the dongle doesn't require external power to operate.
Thus far I'm fairly impressed with SlimPort. I enjoyed discrete microHDMI connections on devices when that was the norm, though finding a microHDMI to HDMI cable was always the challenge. Later MHL seemed a step in the right direction, but requiring three cables to do display mirroring seemed like a bit much. With SlimPort I think we've finally arrived at something close to ideal with the standard not requiring external power to function. It will be interesting to see how SlimPort, MHL, and Miracast adoption fare in the coming year as mirroring to a larger display is in the cards as a convergence trend for smartphones and tablets.

Charges the device while it's connected? That's awesome!

I questioned that at first as well. If you follow the link to the adapter and look at the pics you'll notice that it has a USB input. I assume this has to be connected to charge the phone. As far as I'm aware HDMI doesn't carry power.

Only TVs with built in MHL HDMI Ports provide power.
Sent from my Desire HD using xda premium

I read that the adapter has to have a power source to work... I assume then that this additional micro USB input is to enable use with TV's that dont support MHL.

Nothing like this exists now? Intriguing concept.

Will this work without having the charger connected? It seems nearly identical to Samsung MHL adapters.

I bought one. It seems like the packaging said something about the micro usb port being optional if you want it to charge, but I threw that stuff away and don't have an N4 to test with.
I think the "HDTV Cable" on the SlimPort site is going to be a cable that's micro usb (SlimPort) on one side, and HDMI on the other without any power input.

I ordered one as well
Cant wait to try it

As funny as that sounds, that would actually be nice. I know it's not SlimPort, but I use a Monoprice MHL-HDMI adapter currently. It requires power to work. Unfortunately, it can't negotiate high current and the phone shows USB charge mode. But with the screen active, it ends up losing 10-100ma. I haven't researched the actual micro-usb pinout to see if video uses the usb data pins or what. If somehow it doesn't, I might be able to short them out and have it go into AC charge mode.
Or maybe the better MHL adapters actually do negotiation and do charge?
Either way, hopefully the initial feedback on the N4 is good enough that I can overlook the fixed battery and storage.

My MHL adapter charged my GS3 charged when watching the Avengers movie Samsung gave T-Mobile GS3 customers. It was a pretty slow charge, but prevented my battery from dying like it should have.

I think this would be a lot more appealing in dock form.
The cable+block adapters are always a bit awkward to connect up and actually use in my opinion.

Will an MHL adapter work? I was using one on my GS2 and want to know if I will be able to use it on my N4

the video on this page specifically says that no external power source is needed.

Just ordered one of these Slimport adapters from Amazon since my Google order has just shipped. Reasonably priced and power is optional unlike MHL.

Mine arrived from Amazon yesterday but I can't get a picture on the TV, when I plug everything in the screen on the N4 rotates to landscape and the phone loses sound, all good so far. But when I select HDMI source on the TV I just get a black screen.
This is annoying because the S3 worked perfectly with the Samsung adaptor.

Is your TV set to the correct HDMI port?
Nexus4, Tapatalk

There are apparently 3 dongles out there being marketed with a male microusb and female hdmi output:
Can someone please provide clarity on which ones will work with the nexus 4? Specifically looking for someone to post results for example 1
1. Generic MicroUSB MHL dongle cable : these are sold on ebay and optionally have an extra female microusb on them for OTG or power. This one will NOT work on Galaxy S3 bc of pin change. Can someone report if this type works on Nexus 4? It would be the most affordable solution if so
http://www.ebay.com/itm/MHL-Micro-U...748540?pt=PDA_Accessories&hash=item1e74de5c3c
2. Samsung SGS3 MHL dongle cable: bc of samsung pin change, this cable was specifically required for SGS3. - Reported not working on Nexus 4
http://www.engadget.com/2012/06/09/galaxy-s-iii-incompatible-with-previous-mhl-dongles/
3. Slimport microUSB cable - Reported working on Nexus 4, but pricey
