Tablets to external USB DAC - Page 3

post #31 of 44
something like a voodoo kernel, but it puts in usb audio functionality, would be awesome. my sgs would transform from a beast to an absolute monster!!

it'll be one tough job if it's possible...

It's really not too hard. It's just a kernel compile for the most part. It's very time consuming though. And testing on real hardware is vital.

 

It's traditional for compiles of open source software to be distributed free (both kinds of free). So if I had the time and hardware (which I don't at the moment), I wouldn't break that tradition by charging money.

Definitely testing on real hardware is vital.

 

Yea, time consuming is the worst thing about it. I'm not a programmer myself, but I know how much this eats into time. One small bug takes ages to find and fix without introducing another bug.

E7 or E11 maybe loos more fit for a tablet, as it's stylish look

post #35 of 44
Thread Starter 

E11 is not a DAC. And I'm not really keen about amplifying my tablet's HO.

At the moment, we're not talking about which DACs to use nor how their looks yet,

the more essential thing to accomplished first is how to enable Android kernel to stream out the digital audio to a DAC to be processed further.

We've been waiting for a while yet no good news heard til now...

Desperate waiting. The issue has been starred by 1247 people so far, but still no good news

Here it is, you don't need to wait. Nook touch is just $60 on eBay other tablets are more

Has any Head-Fi'er been able to successfully run USB Audio from an HP WebOS Touchpad?  I have USB host mode working on my Touchpad running WebOS 3.0.5, but I don't know what's required to enable the digital audio via the USB port. I'm not technical, so I'm not interested in runninng the Cyanogenmod, for fear of bricking my Touchpad. Tried to find more info on WebOS Nation, but came up short.  I'd appreciate any suggestions.  Thanks.

I'm resurrecting an old thread, given that I've had success with the subject at hand -- outputting digital audio from a Tablet to an external USB DAC.

 

On the new Samsung Galaxy Tab Pro (10.1) I've been able to send audio via Micro USB OTG successfully to three entry level USB DACs: 

 

1) AQ Dragonfly v1

 

2) Audioengine D1

 

3) HRT Music Streamer II

 

  

1) AQ Dragonfly v1 - I also posted in the original Dragonfly thread, but the volume level output by the Tab / DAC combo was just moderate.  I could max out volume on the Tab and still be wanting for more, so this combination wouldn't be suitable for full sized cans. 

 

That said, the SQ with my UE10s was quite good.  The neutral character of these IEMs paired nicely with this bright DAC.

 

2) Audioengine D1 - I was able to extract much higher SPLs with this DAC / amp, maxing out the Tab volume, controlling output volume via D1.  More punch isn't necessarily better, however, as this DAC is considerably muddier in clarity vs. the Dragonfly.  

 

3) HRT Music Streamer II - Since this is a DAC-only product, I hooked it up to Magni / Mad Dogs, and this combo was solid.  Good clarity, good power, drove the Mad Dogs quite nicely.  The HRT registered a "48khz" signal coming in, regardless of the source file.  There's a good amount of compression going on,however, as artifacts were pretty apparent.  

 

This was a fun experiment, seeing how new source tech finally plug-n-plays with older USB audio tech.

 

FWIW, my LG G2 phone was able to output OTG USB audio to the Audioengine D1, but not to the Dragonfly nor the HRT Music Streamer II.

ohoho! That's good to hear! I've wanted a Tablet my self... as it's got a multitude things it can do, take pics, browse head fi ect... like a mini PC, which is what a Tablet is...

 

still I'm happy to hear it works :3

 

and man the dragon fly looks very nice with that set up! A shame I don't own iems

Hasn't usb audio been supported in part in android 4.1?

I'm running USB Audio on an Asus Transformer TF300 with Android 4.2.  I don't think it worked under 4.1, at least not on the Transformer.  I tried it occasionally and never had success until 4.2 was pushed.

 

Also, I have to reboot each time I connect my device.  When I plug it in, the sound goes to USB, but sounds "underwater", like it's missing samples.  But then I reboot with it plugged in and it will work properly until I unplug the device.

 

So it's not perfect yet under Android 4.2, but pretty good.  4.3 and 4.4 may be even better.

A bog standard pc audio setup looks like 'music on hard drive>pc media player and usb out>dac>amp>headphones'

 

I just was looking for a sub £150 small piece of equipment that replaces the 'pc media player and usb out' from the above. Just a magical device that takes out the pc from the equation. I don't give a monkey's about other functions of this device- and would prefer if it didn't have any.

The best I could do is use my smallish netbook- installed with the most power/heat efficient ssd around- to get a result (rumor had it that the upcoming fiio x3 would have such a feature but no)

 

Is it just me and a few other headfiers who want for such a thing?  

 

I can't find any old i-rivers, and i'd rather spend on headphones than £500 for a device that for me only would be used for its digital audio out via usb.


I realize I am reading this 3 years later, however I am currently in the same situation as you were. I currently use the set up you mentioned with a computer in the stream. I am looking for the solution you mentioned. Did you ever find a solution using a Samsung Tablet?

post #44 of 44

Quite some time yea!

 

There's plenty of things now that work like this.

 

- Samsung S3 has usb OTG out. Just connect some small dac/amp, like the HRT microstreamer / graham slee bitzie, with a USB OTG cable.

 

- Fiio x5 does the same, though via optical out. 

 

- Asus Transformer T100. Fully fledged PC that's also a tablet. It's got full windows 8.1 and USB OTG out in the tablet itself. The removable keyboard has a full on USB output.

 

 

I use the Last one.
