Thanks!

I will include it in the S3 compatibility list on the page 135.

Android USB audio... What a blessing!

 

Any information on the Motorola Droid RAZR (XT910/912)?
How can I tell whether my device (Stock kernel running D-WIZ 4.1 ROM) can support digital audio out?

According to the latest compatibility list on page 130, USB DAC can work with stock Motorola Razr Maxx HD using the USB Audio Recorder PRO, available on Google Play store.

There is a trial version.

Thanks for the quick reply.

 

The background story is that my trusty J3 busted on me last week so meanwhile I'm mobilizing with my phone (which I'm really disappointed with). I'm thinking of getting a portable DAC/AMP to hook up with it but I don't want end up with an unusable $100-200 component in case the phone can't communicate with the DACs.

 

I was talking about the older RAZR. Droid razr and droid razr MAXX a.k.a. XT910/912. Motorola's equivalent of the SGS2. HD is the newer, SGS3 equivalent ones.

Search queries here came up with nothing and search engines only come up with car dock experiments and not DACs or sound cards so I thought it was worth a shot.

 

Also, I don't really seem to catch what the limitation for driving an external DAC through the USB is. Hardware? Kernel? Rom?

 

Cheers.

. Hardware:

Several phones don’t have the USB OTG hardware components, so that they could not act as USB host.

They can only operate as USB peripheral; they can’t work with standard USB DACs that only operate as USB peripheral.

 

. Kernel:

Several phones don’t have a complete USB host driver, so that the USB Audio Recorder PRO app, that includes a USB audio soft-driver, can’t use the necessary USB service to drive a USB DAC.

 

Several phones don’t have a USB audio driver, so that music players using the Android media player framework can’t forward a PCM stream to USB DAC.

 

Several phones have a perfectible USB enumeration that stops interacting with USB DAC at the slightest obstacle.

I haven't found any information about the Samsung Galaxy S3s' LTE enabled twin brother: the S3 GT-I9305 in this thread.

I received mine last week, and did a little OTG cable DIY this evening, and I'm really happy that it works :D

 

Tested with both my E7 and Odac (Epiphany Acoustics EHP-O2D, for what it's worth), and both work.

 

 

Test setup 1:

Samsung Galaxy S3 GT-I9305 playing FLAC using Poweramp2 > DIY OTG cable > Fiio E7 > Westone UM3X

 

Test setup 2:

Samsung Galaxy S3 GT-I9305 playing FLAC using Poweramp2 > DIY OTG cable > Epiphany Acoustics EHP-O2D > Audio Technica ES-10

 

 

 

I hope it will work with my iBasso D2+ too...as it can do Line out, which would be good for hooking up to my car audio system. (And the D2+ would see some use again as I still can't get it to work on my Ultrabook :/)

 

Update: iBasso D2+ works too :)

Does the Fiio E07K work with Note II? Danba's extensive list still listed it as to be confirmed.

Got some more listening time with the PCSTEP today... Very, very impressive. The words "clean" and "transparent" kept coming to mind while listening. I was initially a bit miffed by the use of a 9V battery instead of a built-in rechargeable battery like everything else, but now that I've been able to listen to it extensively for many hours while travelling and being stuck on the side of the highway (long story), I find myself much more appreciative of the additional battery life this give me. I don't want to say too much more before I have time to sit down and do a more detailed examination, but this thing has a ludicrously low noise floor, which I imagine is one of the factors that leads to the clarity of the sound. 

 

So far, a BIG thumbs up to Jan and company beerchug.gif

Any comments yet on it vs the Apex Glacier?

Thanks for the heads up.  Enjoy the LTE and extra gig of RAM over the i9300.  And if you decide you hate Touchwiz, there's now a build of Paranoid 3.15 for the i9305.  I wonder if Jack Norris' excellent USB audio patch would work with it?

And here's the result of DIY OTG-cable attempt 2:

Nice job, you can now start a cable company, I bet many would but one from you if it is priced right wink.gif

Possible to use right angle connector on both ends to save space?
post #1978 of 5390

I apologize if this question has already been answered elsewhere but I haven't been able to find it after considerable searching.  

 

I have a Galaxy Note I (SGH-I717D) and a Leckerton UHA-6S.MKII.  I understand that the Note is not capable of sending USB-Audio under ICS.  I have read that Jelly Bean supports USB-Audio but there is some doubt as to whether the Note's version of Jelly Bean will support USB-Audio.  Does anyone here know for certain whether Jelly Bean on Note will support USB-Audio such that I will be able to use my UHA-6S.MKII's DAC directly, bypassing the Yamaha DAC that is on-board my Note?  I know that some parts of the world, and some ROM users are already running Jelly Bean on their Note(s); could anyone here verify whether USB-Audio is working or not?  

 

Thank you for your time and consideration.

 

Regards,

 I Wish... Unfortunately, there's not a lot of choice when it comes to micro & mini usb connectors for DIY. And even less when you want right angle connectors. There are a few available, but on most I saw, the housing is so massive they hardly offer any advantage over regular straight plugs.

Thanks for the info. Neat job!
