How about a picture of Galaxy S4 + CEntrance HiFi-M8 + JH13?

Can you play 24/192 music files?

Where do you get the iBasso OTG cable?

 

Thanks!

I'll take some pics and transfer some 24/192 files to try out when I get home in a few hours...

 

the ibasso otg cable comes stock with the d42 dac/amp. The cable is not listed anywhere else on their website, so I don't know if they'll sell it by itself.

If you think your phone port is clean...here is what I got after cleaning mine with the method a few post back and mine is working normally.

Is there a place to update the list of supported hardware? I have just tested the Sony Xperia ZR with my FIIO E7 and I'm happy to report that it works right out of the box, no need to install Audio Recorder Pro. Thanks DanBa for coming up with the list. May I suggest this list be stickied?

Great news!

 

Hopefully, you are working with music player developers on interfacing your USB audio service.

Worded differently does that mean that if you are rooted it should be able to work with any audio / video player or indeed any other source without needing any in-app audio routing support?

Very good news though! I'll just wait patiently for USB OTG support to come back to the 3.4 CM10.1 kernel now.

You need also verify that you can play true 24/192 without re-sampling.  Fo example I listen to mostly to 24/192 formats on my phone. But I know Kamerton resamples music to make it compatible with limitation coming from ALSA. So if you can bypass ALSA then you can play true 24/192 music. Generally it is fairly easy to do however you need root your device. If you know how to do that without rooting then let me know.

That is worded differently, but not the same! :-)

The apps will need to support the USB audio service that I'm making. I have been in contact with two player apps and as soon as it is finished, I will contact them all.

Sorry, I don’t understand why the Android device has to be rooted when using your upcoming USB Audio Service and a music player, "at least in 24-bit and high sample rates". (Heck I’m not a developer).

 

Your USB Audio Recorder PRO does not require Android rooting, and can forward a 24/192 stream to 

a 24/192-capable USB DAC like the Cypher Labs AlgoRhythm Solo –dB

1000

 

 

or a 24/192-capable USB DAC/amp  like the CEntrance HiFi-M8.

I meant to say that, now, on specific device models like S3 and S4 without root, you can play USB audio on a selected number of DAC's with UARP. This functionality is limited to 16-bit and I can only assume it's limited to the sample rates that are available for the internal audio chip, but I'm not sure. If you have a S3 or S4, can you play at 96kHz or only up to 48kHz?

 

If you have root, I assume that some hacker can make something that will allow higher rates, but it will also be restricted to 16-bit, since the Android API only allows for 8 and 16 bit.

 

Now with UARP or the USB audio service (with or without root, it doesn't matter), you will be able to do 24-bit at any sample rate that the DAC supports. I hope this clarifies. I'll edit the previous post too.

Without USB Audio Recorder PRO, my stock Galaxy S3 with some music players can play 24/96 music files, but it can’t forward a 24/96 PCM stream to a 24/96 USB DAC.

For sure, but it will get resampled and converted to 16 bit.
