Android phones and USB DACs - Page 103

Hi,

I don't know if it will help but if you were using your Minix G4 rig at home or where you are connected to a network, you may be able to use Bubble UPnP as it has a setting to open on boot up. I do not know if the remote could be used with this but it can be controlled with a 'phone. I have recently been experimenting with a Samsung Note 10.1 connected via a hub to a Behringer UCA202 dac and an external powered drive, the output from the dac going to my hifi and controlling it all with a Samsung 4.2 media player ( which is just like a 'phone but does not make 'phone calls ! )  Bubble UPnP is installed on both the tab and the media player, with the media player acting as the controller and the tab the renderer.

I can confirm that Jack's patch works perfectly on the i9300 running AOSPA 2.99.  Now to flash Liquid Smooth as a second ROM.  Android nirvana is at hand.

i want a portable dac/amp to go with my i9300 and ue6000 headphones that's under $150. Any suggestions? I am thinking of getting the xperia z soon so I want a dac that can give me better sound with the z than I can get with the s3 w/ wolfson dac. 

Have you tried comparing use time of your 7 and DF with and without the external battery?

 

Going off reputation only, I'd say the iBasso D-Zero might be a good fit. I researched those, found pretty much universally positive reviews, and ordered one for my mom. Hasn't come in yet, so I don't have her impressions and I haven't heard it yet, but there are tons of reviews online if that helps. 

Not yet, I just got my Y cable today. I'd expect the battery life of the 7 to improve by a bit but I'm not sure how much the DF draws. USB Audio Recorder PRO is, to me, pretty useless as a media player so I dunno what to do :( 

Anyone know if USB audio works when video is being run through HDMI out? Please help me justify an external DAC/amp. My fathers home theatre system doesn't do hdmi sound so if it works I have a perfectly logical reason for spending the money on head-fi gear

Did you try the jacknorris' USB Hotplug patch thats on XDA Developers yet?  Which kernel are you using? 

 

I have both the the USB hotplug patch, and flashed Timur's kernel on my Nexus 7.  I had a chance to do a quick 10 minute test with the DragonFly.  When I plugged in the DragonFly straight into the N7 via the OTG cable, the dragonfly lite up (a good sign), but both Neutron MP and the stock music player produce any music.  I think the problem is the volume control... as of right now, there is no way of controlling the volume when you have the DragonFly plugged in.  Once jacknorris tweaks the patch, then it might work.

Sorry if this is not the right place to post this, but this seems to be the central place for android-DAC discussions (and couldn't find an answer elsewhere...)

 

The sound of my old ipod is bad, but still better than my quite crappy HTC sensation. Since i already have a Fiio E7 i now eye a chance of playing music through the E7 using the HTC! This would allow me to completely forget about the ipod + itunes combo, while enjoying vastly improved sound quality!

 

So the questions:

 

1) Which version of android is necessary (i have 4,0,3)?

 

2) Which cable is necessary? Does it have to be OTG capable?

 

3) Does the android device automatically use the best bit-rate (most of my files are FLAC/apple lossless)? Maybe it is a matter of using the right player app (i use PowerAmp currently)?

 

Any help is greatly appreciated!

I'm using jacknorris' USB hotplug patch on top of a stock 4.2.1 ROM, and the 4.2.1 kernel in his thread. 

 

BTW - what color does your DragonFly light up when plugged in? Mine is always pink unless USB Audio Recorder PRO overrides it. 

 

I did see an ALSA error message in the kernel log. The kernel is definitely detecting the DragonFly but still no sound comes out. I'm no stranger to the Android framework and kernel so if it's an easy fix I might look into it myself.

The HTC Sensation is on the not working Android device list of the USB Audio Recorder PRO website.

Any suggestions on getting hotplugging working on a Nexus 7?

 

I am forced to reboot the device with the DAC plugged in to get it working which is frustrating.  

 

ROMs tried: ParanoidAndroid, LiquidSmooth

Kernels: M-Kernel, Timurs

DAC: Audio-GD FUN

 

Thanks!  

I'd just like to report that I've been using jacknorris's (1.1) patch on my i747 S3 with LiquidSmooth (2.1 beta 3.2) the last couple days, and I'm delighted with it. The main audio output switches beautifully to my Intruder when I plug it in and back when I remove it. And I love this google-experience ROM as well. (I'm a CM & Paranoid Android fan, too.) I've noticed that the audio doesn't switch to the minijack port when you plug in some headphones or whatever, but it's not killing me because I use bluetooth for podcasts and the big guns for music enjoyment.

Also, I managed to get DSub to stream pure FLAC from my server, so I kind of have a bottomless collection of lossless music on the ready on my phone.

I've been waiting years for this moment. lol.

Here's an ultra crappy picture of what I'm talking about.
