Android phones and USB DACs - Page 229

post #3421 of 4565

3 questions about Sony xperia Z (the smartphone, not the ultra, not the tablet and not the z1) and Fiio E17 (500mA)

 

  1. does it work with Fiio E17 without hub? (the only video I found was using hub but there was a floppy disk connected too xD http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/1725#post_9177284 )
  2. uarp is required or it works with all players?
  3. 24bits only with uarp, right?

update:

Samsung Note 3 snapdragon works with Dacport LX , only when using Google Music player!!!

 

That makes me conclude that google is really using a separate kernel for USB in its player, as per UARP.

 

The least favorable player!!

 

Another update : if you leave the google play music player running in the background, all other players will work!

Neutron , Poweramp Player Pro, Samsung player.

Are you talking about Note 3?

Yeah.

The exyons sounds more open with better detail than the snapdragon.

I have the snapdragon Note 3. I find that if Google Play Music is running in the background, then Poweramp's SQ is degraded significantly. I disable Google Play Music (so that it doesn't open itself) when I intend to use Poweramp. I imagine it's different when using a separate DAC.

 

There are times when the SQ of the Note 3 (using Poweramp) seems to degrade for reasons that I have not been able to link to a causation. I guess because it is a complicated smartphone with 44 background processes running at any given time that I clear the RAM (who knows?). I do know (for the first few days) it sounded great. However, yesterday, my Galaxy S2 sounded better. The S2 has a real slimmed down ROM on it that I got off of XDA Developers.

I agree with you, that is why I use the Apex glacier with my Note 3.

It gives me an excellent sound, until I get the Sony ZX1, its my favorite portable.

I'll be glad when my OTG cables get delivered. I bought two kinds; the standard micro-USB and the one with the Note 3 connection. Will either work or must it be the Note 3 specific one?

The extra pins on USB 3.0 connectors is only ground and superspeed transmit + and -, and superspeed receive + and -.
They will be unused without a USB 3.0 device connected. So it should not matter at all.

This is very interesting. Can you try different sample rates and see if the DAC sample rate indicator changes at all?
By kernel, I think you mean driver.

USB3 is compatible with the old micro USB2 standard, so no need for a new otg cable.

I use my old micro USB.

This will work just fine.

Thanks, headfinoob.

 

BTW, you don't sound like a "noob".

Thanks, Turokrocks. That picture looks like one of the (two) OTG cables that I ordered. Which ever comes first, I'll get to experimenting with DACs.

My Dacport LX has no indicators, so I connected it to my Asus Essence muses xonar one, and strangely in all songs and bit rates it stuck on 48!

 

Only USB recorder pro was able to change to the appropriate sample rate!

Any ideas?
