By the way, how about the implementation of USB HID (Human Interface Device) to allow Volume Up/Down Control of the HRT microStreamer from a USB host like a Xperia Z or a Galaxy S3?

 

"Dual purpose built, it incorporates both a high–performance headphone amplifier with an analog volume control that allows you to connect the microStreamer between your computer and headphones...

Volume control of microStreamer’s OCL (output capacitor-less) headphone amplifier is accomplished by using the digital ‘slide’ control on the host computer’s music playback software to adjust microStreamers’s internal analog volume attenuator. This clever analogue attenuation arrangement allows the full audio quality of the microStreamer to remain pure, clean and full-ranged, avoiding the known sonic degradation of digital attenuators."

Just got an S4. Loving the phone, hating the headphone out. Im wondering if either the Audioquest Dragonfly or the microstreamer works directly with the S4. I've been reading the past few pages, but I'm not familiar with all the android terminology used, so I can't seem to pick out the answer. Im limiting my portable setup to those 2 devices because they seem to be the smallest ones out there. Any help would be much appreciated!

The interworking bug between an international Galaxy S3 and a Pico was fixed: no more need to use a USB 2.0 hub.

With my US Verizon S3 + OTG cable:

- FiiO E7 - works

- Pico - doesn't work.  What am I doing wrong?  Could it be I have an older model Pico Serial #2xx?  (it works with a powered hub, though)

Justin at HeadAmp found a fix, I sent mine back to him to have it done, but he said if you're handy with a soldering iron its easy. Get in touch with him.

So the CEntrance DACport LX does not work with USB OTG? Turokrocks I now have: Note 2. DACport LX. Android 4.1.2. Is it still just the reality, that the DACport LX is a fail? I guess it sounds good, but it doubles as a space heater, and that will drain the cell battery.

 

Did anybody get this DACport to work? Do I have to root my Note II and try Paranoid Android?

 

I asked CEntrance about this 6 months ago. It appears that for marketing or technical reasons they have not fix this. What is my next choice? Should I sell the DACport LX and buy a Leckerton?

Simply email me at info AT audio-evolution.com for any issue you have.

 

I'm not sure if it has up/down control. Usually, it's the other way around: the device has a physical up/down knob and the software gets a trigger when you press it. Anyway, they talk about volume control: I cannot check here, but I assume the mixer tab shows the volume control you mentioned?

I didn't follow the discussion, but I just wanted to mention that I have the DACport LX on my compatibility list, so one or more of my customers of USB Audio Recorder PRO have it working. I know it's not your ideal music player, but you could at least try the free trial if it works on yours.

I confirm with USB Audio Recorder Pro, the LX is working with the Note2, and what a sound!

I appreciate the replies. I suppose USB Audio Recorder Pro would work as you say. Though its author stated that he doesn't intend it to be a full featured audio player. There are lots of excellent players for Android and it seems a shame not to be able to use them. 

 

I'm sure the DACPort LX has wonderful audio qualities. Maybe rooting my device and installing an alternative Android would at least allow me to use one of the many excellent full featured music player softwares. But Turokrocks, how long does the Note 2 battery last when driving it... the DACport is a regular space heater. I could run the test... won't take long... I could practically watch the battery meter dropping with my eyes. Hardly portable, and even at home, more cable that get tangled (USB hub... power to it...)

 

CEntrance doesn't seem particularly interested in fixing the problem on their end, or even acknowledging that its a problem. I think overall its just not going to work for me. Right now I'm using the built in DAC. I might get a Leckerton some day, but then I'd have to forego my Tralucent. 

 

Again the amazing thing is how the DAC is hot while the amp runs cool. I'm curious what part of the DACport circuit burns so many watts.

Hi Guys,

 

I was a happy owner of a Galaxy S3 and a ODAC + O2. 

I replaced my phone by a Galaxy S4 International (i9500) and was very disappointed to find out that the Galaxy S4 is not compatible with the ODAC. No sound and play in fast forward. 

How could samsung remove compatibility for newer devices? Thats stupid. 

Anyone knows how I could get it to work? Is USB AR Pro a possible solution?
Thanks!!

I don't think Samsung removed the drivers. Recent android os has usb audio built into it. Try rebooting your phone, that solved a issue for me on S3.

Ok. I will try that tonight. I hope it helps, though I don´t think it will. 
Thanks.

I confirm that S4 did not work with any of my DACs that used to work with the Note 2 (Apex glacier and ODAC), so I skipped it, maybe the HTC one (the one with the microSD) will be my next purchase.

 

Samsung indeed removed support for DACs in S4, welcome to the future!

If this is true and remains uncorrected, I can definitively say I will not be purchasing an S4, although I had a strong interest at one point. I know we are a relatively minor niche of the greater market, but USB audio is an incontestable requirement for me. Hopefully this is something Samsung can fix with a firmware patch rather quickly.
