->[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.

hi,
I'm new to android phones. I wanted to connect my copy of the Nexus 4 to JBL On Stage IV, which I used with my old iPhone. Unfortunately, after using the micro-usb adapter my phone is charging but does not transmit music to speakers. I would add that I have system :Nexus 5 Experience ROM [4.4 KK] Rooted.
Can u help me ? Can i use my JBL On Stage whit my nexus 4 ?

The USB port on that device probably does not support MTP, so it can't directly pull music off of the storage. It also was released around 2010ish (Based on a quick Google), before Android got the capability to send audio over USB so it does not support the Android standard. It will not be able to output over USB. You're going to have to use a 3.5mm cable to connect it to the headphone jack on the Nexus to get any audio output.
Ok, thx 4 help. Now i will buy 30pin to mini-jack adapter on ebay .
You can try one of those Apple 30pin <-> Bluetooth adapters. That way you can charge your phone over USB and just send the audio over Bluetooth to the dock. Something like this: http://thewirecutter.com/reviews/the-best-bluetooth-dock-adapter/
I'm hoping that with the new USB Type-C connector and Power Delivery 2.0, someone will finally make my ideal type of DAC for phone use in the car:
USB input for powering DAC from cigarette lighter adapter (2.1A)
USB input/output for connection to Type-C jack on phone - phone sends digital audio to DAC, and phone simultaneously charges at (relatively) high power thanks to Power Delivery 2.0
3.5mm audio line out - connect to car AUX input
Currently the DACs I find that come closest to meeting this are the FiiO E18 and the Creative Labs E5, but both add a lot of expense and complexity in trying to be everything to everyone (internal battery for portable use, headphone amp with volume control, etc.). Reviews also state that using them with a phone while also charging the phone can be very touchy.
Is anyone else looking for something like this, or have ideas about where it can already be found? I'm not averse to using a portable DAC in the car, but I want the phone charging to be pretty bulletproof. :good:
I use this with my Nexus 5 and a USB OTG Host cable. I have a Nexus 6P on the way, and I'm hoping it will still work with a just a micro-USB to USB-C adapter for the Nexus 6P. It works very well now, with the downside that the phone doesn't charge when used this way . I read that that was a hardware limitation in the Nexus 5. Maybe the Nexus 6P will charge while sending USB audio, I don't know.

I don't know of a product that matches what you described. I have the OPPO HA-2, but in terms of inputs and functionality, it's much the same as the SoundBlaster and FIIO DACs. I don't see how you can charge your phone at the same time you USB output the audio to one of these devices. Using the analog jacks defeats the purpose.
While I think the setup you described would be good, I think we are probably a year or two away from anything like it. I've noticed a trend in the audiophile world of slow adoption of new things such as USB Type-C. If the market proves me wrong, I'm OK with that! I just don't have high expectations for something like this anytime soon.
Also, I think a better alternative would be an aftermarket deck for your car with a USB input for simultaneous charging / USB audio connectivity straight to the sound system. Skip the external DAC and analog headphone jacks all together. Maybe something with Android Auto on it. Again, adoption of Type-C is probably going to be very slow in this product category, but that would be something I'd like to see!
Besides, audio always seems to limited by the weakest link in the chain. Factory car speakers are just terrible, although I'll admit they've gotten better in the last 4 or 5 years. Why go through the pains of setting up an extravagant DAC setup when the speakers won't make it sound any better? Unless you DO have better speakers, in which case, never mind.
May I ask why the 3.5mm analog out from the phone is not sufficient if your car already has an analog input? What is this buying you?
I have an old 2005 Acura TL with a kickass stereo (DVD-A), but no external inputs. I just installed a Grom Audio AND2 that gives me USB stick, Android and a 3.5mm Analog capability. Mine is running in Satellite Radio Emulation mode to give me Song, Album and Artist info in the display.
As newbie, I can not be helpful and add a link but you can Google Grom Audio and click the compare kits link.
The holy grail for me is automotive systems that will take USB or SD cards and actually have as much functionality as a free app on the play store! Most automotive entertainment system developers are so clueless, they should have their balls crushed in a vice and then be fired! The whole naming audio files "01-Artist-Album-Title" came about because automotive systems won't read metadata tags and support playlists.

My 05 TL is also Navy Blue with British Tan leather. Now it has a Grom Audio and I am a fairly happy camper. I used to burn DVD-A discs with about 7 CDs on each and use the "Group" feature. So the 6 disc changer gave me about 42 CDs. BTW, I used Cirlinca DVD-Solo to make and burn DVD Audio Disks.

We have the exact same car

Hi, everyone. Thanks so much for the responses, I really appreciate it. To answer some questions and hopefully clarify things:
Why do this? In my 2007 Honda Civic, I upgraded the speakers just after I bought the car (Boston Acoustics) but left the head unit alone, to get maximum sound quality bang for my buck. I currently have a Galaxy S4, and can take advantage of analog audio out via USB with a special iBolt cable (It operates very similarly to the old 30-pin iPod to analog out cables, if you can picture that).
Via experimentation, I've found that increasing order of sound quality is:
Connection from headphone output to AUX in
Connection from USB analog audio out to AUX in (via iBolt cable)
USB digital out over OTG cable to external DAC, DAC AUX out to car AUX in
Option 3 is far and away the best sound quality. It's a very noticeable difference--as good as playing a CD in the head unit. I will use this option with the Nexus 6P no matter what, but I'd like to be able to charge the phone at the same time, especially on long road trips while using navigation and playing audio. Both the USB Power Delivery specification 2.0 and Android Marshmallow make reference to being able to charge USB host devices, so the missing link is what the best DAC would be to achieve that. It may be that the phone itself will be able to decide whether to draw or output power, which would be ideal if the DAC recognizes and respects that choice.
As for the question about why not get a new head unit? This is an older car, and it's frankly not worth the expense and effort to do that at this time. I'll definitely be looking for Android Auto as a feature in any new car I consider down the road, however.

The GROM kit I bought allows me to play music from USB stick, connect the phone via USB and drive it from the car interface, and aux in. The USB3 kit allows you to add a Bluetooth. I prefer the music on the USB stick. Better connecting a $5 stick than a $500 phone.
The 6P is not USB-PD compliant in that it does not support the PD profiles. 15W (5V/3A) is not a PD spec. It is a Type C spec. Supposedly it uses the control channel in the type C cable/connector but no one knows how far it goes. Some suggest that it will allow reversing power flow. It should allow both data flow and power flow, but it is not a full implementation of USB-PD and is still only USB 2.0 compliant. It should allow charging while connected as long as the host it is plugged into will provide power. At what rate is the big question. Most assume it will drop to legacy 5V 1.5A.
Thanks, dwswager, that's good info. I have a Grom Audio unit in my wife's Mazda, which lacks an AUX in. I'm not 100% happy with it because it tends to lose the ability to get digital audio from the phone, and she needs to reload a config file from a USB stick to reenable that.
I do tend to think that all of this will get worked out in the end. I'm a bit of an edge case, I admit. I do have some good stopgaps now, at least for the non-charging case. That Turtle Beach mini DAC is quite intriguing at only $20. At that price it's worth taking a chance.
I hope we can keep this thread alive as we start to discover what works and what doesn't. November can't get here soon enough!

Assume you have spoken to GROM. Also will assume you flashed the latest firmware update to your wife's unit. The downside on the AUX input is that it uses a proprietary DIN-4 connector and the cable they supply has a male 3.5mm end. So if you want to mount a female 3.5mm jack in the dash you have to use an extra F/F adapter because the jacks are all wired with 3.5mm male ends. They also make an aux cable with both 3.5 and USB female so you can charge and output analog audio at the same time. You also get standard 5V 1.5A via the USB port in the AND2, USB3 and the ipod only number.

In terms of audio quality, the Turtle Beach DAC is a serious improvement over just using the 1/8 in. out of the phone. I will say that the Bass response is HUGE coming out of the Turtle Beach, so I usually eq the bass down a couple notches on the car stereo. That said, it really is an amazing improvement in sound quality for very little investment. (I'm a musician, so I tend to fixate on these things.)
By the way, I bought this cable to extend the reach of my OTG / Host cable,
http://www.amazon.com/gp/product/B00HAOKCE8?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00
It's interesting that the seller says USB OTG cables do not support charging.
"This cable is what is known as an OTG, or On-The-Go cable. USB On-The-Go is a specification that allows USB devices such as digital audio players or mobile phones to act as a host, allowing other USB devices like a USB flash drive, digital camera, mouse, or keyboard to be attached to them. These cables do not support charging or syncing of devices. "
bump.
Has anyone found a portable solution to charge phone and offload digital audio to a DAC?
I'm happy to say that the phone works great with my Sony UDA-1 dac/amp (both audio and charging), but it runs off of mains voltage.
I'd even be happy with any single cord solution for simultaneous charging and audio output.
Alright, lemme clear some stuff up here.
For most phones, yes a USB DAC provides better quality than what comes out of the headphone jack and also more volume (doubters can just live on in ignorant bliss :good
On my LG G2, at least, the OTG Y-cable linked earlied charged the phone (although it didn't actually seem to indicate it was charging) and worked with the DAC at the same time
The same cable, when converted from micro USB to USB C and used with the 6P, seems to only be providing charging, the DAC is not working
I will see if I can find anything in the logs or whether there's anything else I can do, maybe bypassing the Y-cable to see if the DAC works at all with the 6P.
Yeeesss yes please, if you or anyone else happens to get a DAC working with the Nexus 6P, please let us all know. I love my 6P, but I definitely miss my setup with my OnePlus One + USB DAC to car AUX...

No, not at all.
There's also noticeably less noise through the DAC compared to my old Galaxy Note 3.

also, I installed the trial version of USB Audio Player Pro , and I was able to get stereo sound (though limited to the interface of that app and only local files). So there is something really weird happening software wise . . .
Well I tried a USB C to A converter, and my DAC is working fine with the 6P with that. But no charging at the same time, of course.

With no headphone jack - and at times a need to charge and listen - it is either bluetooth headphone or getting a usb-c dongle that does both charging and headphones in one ( for nighttime - for car). I am less of a bluetooth headphones guy ( hate to have to deal charging headphones) so was looking for a simple usb-c splitter that does both headphones and charging. Trouble is there are articles and reviews stating how many of the these dual usb-c dongles do not work (they do not charge) on many different kinds of phones . Has anyone found a good one that works ( charges while listening) on the mi A2. I see this has better ratings than many others.
Can anyone also reccomend a good working faster charger for the mi A2
if you're looking to use the phone while driving car, you could always get a bluetooth module to hook on your aux input.
as for charging it, really you could just hook up the module to your car charger all day, it won't damage it. Maybe just use those lighter charger with multiple usb in it, so you can hook the bluetooth module on one port, and the other port for your phone.
I have done reviews of the Soulsound Dongle on Essential and Pixel 2 and I am impressed. Fast charging works on both those phones and sound quality is amazing.

I can confirm that the Baseus L45 Type-C Male to Type-Female + 3.5mm Female Adapter works flawlessly on Mi A2, running stock Pie 10.0.2.0. I can do voice calls (both phone calls and games, tested with PUBG Mobile) and charge at the same time. Mic works. I use a Xiaomi IEH Pro HD, headset remote volume control works, middle button works to bring up Google Assistant. The adapter costs me $5 in Indonesia.
Product page: http://www.baseus.com/product-295?lang=en-us
Volume might be a little low (around the same as the stock dongle) but that is due to a software bug on the phone that followed EU's low headphone volume regulation regardless of whichever region we chose. @onbeskarakterli fixed the bug through a Magisk mod (needs to unlock bootloader and root): https://forum.xda-developers.com/mi-a2/themes/magisk-low-headphone-volume-fix-t3886008
Now it sounds AWESOME.
