Android phones and USB DACs - Page 284

post #4246 of 5143

I really like the DAC they used in the 4.2, I've read many reports of it sounding better than the 5 (Which I haven't had the chance to actually hear)... But it suffers from the same problem. Slow as heck.

A thing of the past, I use a FiiO E18 when mobile which sounds far better than the Galaxy Player. I'd like to be able to hook up my GS3 to my Schiit Bifrost. I emailed them some technical questions, perhaps when I'm done finding out if there are any power hassles connecting it via USB OTG, and it's safe, I'll give it a go.

I believe you are confusing FLAC and WAV. FLAC is compressed and so must be decompressed, WAV is not. And I was not saying that the problem was due to processor load, I said it appears to be due to a recent software delivery. And with regards to root cause, I use the term as we usually do; but is that really something worth bickering about?

Confirmed

 

Smartphone: Samsung Galaxy Note 3

OS: Android 4.4.2

DAC: M2tech Hiface DAC 32/384

 

Re: Neutron Amp plays DXD files (.wav 24bit 352.5khz) to DAC.

Yes I was incorrect about FLAC and compression. You were incorrect about Root Cause Analysis, it is not what failed it is why the failure occurred, generally process related.

"A root cause is a factor that caused a nonconformance and should be permanently eliminated through process improvement."

"Ask Why 5 Times."

They would be related to: "Why the software failed?"

Dear fellow head-fi'ers, can I modestly ask you for some advice? I would like to connect my Nexus 5 phone to my Apex Glacier, and I was thinking this cable would do the trick: http://forzaaudioworks.com/en/product.php?id_product=55 . But... I'm in doubt about what to specify in my order. For a Nexus 5, would I need a USB Micro-A on one side and a Micro-B on the other? Or would I need two Micro-B connectors? Please help... (And if possible: explain, so I'll understand.) Thanks!

post #4252 of 5143

For the 1st end, specify the micro-b connector with OTG function, which will enable the Nexus 5 as a USB 'host' and for the 2nd end, which plugs into the Apex Glacier, specify the micro-b connector. BTW, I don't think you'll be disappointed with Forza Audioworks.

post #4253 of 5143

Yes

Nexus5 - Apex Glacier USB OTG cable from Forza:

http://forzaaudioworks.com/en/product.php?id_product=55

. "USB (1nd end): USB micro-B (with USB micro-A functionality, OTG enabling)" to be plugged into the Nexus5, then acting as a USB host or A-device

. "USB (2nd end): USB micro-B " to be plugged into the Apex Glacier, always acting as a USB peripheral or B-device

 

 

How-to:

http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/4185#post_10306075

 

Plug & Play, if every USB audio-required component is functional:

 

 . Required software

The stock Google Nexus5 doesn't have a native USB audio feature.

https://code.google.com/p/android/issues/detail?id=24614&sort=-stars&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars

http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/4185#post_10306075

To work with a USB DAC like the Apex Glacier, the USB Audio Player PRO (UAPP) app available on the Google Play store is needed. A USB audio feature is included in the UAPP.

 

. Required hardware

Nexus5, USB OTG cable, Apex Glacier

The pin 4 of the "USB ("1st" end)" of the USB OTG cable from Forza is connected to its pin 5 (USB micro-A functionality, OTG enabling) so that the Nexus5 is configured to USB host mode able to interwork with a USB peripheral like an Apex Glacier USB DAC

post #4254 of 5143

Thank you sir! At least now I know which cable to buy, but... I'm in doubt if the N5 supports digital audio out over usb. Been reading this: http://forum.xda-developers.com/showthread.php?t=2511921. Has anyone managed to connect an Apex Glacier to an N5?

 

Only reason I would want to use digital audio over usb out is because I want to use it with the Qobuz app. (Finally: streaming in cd quality!) But then the Qobuz app must send digitial audio to usb out first...

. Stock Google Nexus 5

As Google doesn't yet support USB audio (i.e. digital audio out over USB), there is an ongoing request to Google for supporting USB audio, or there is no native USB audio available on Google Nexus 5.

https://code.google.com/p/android/issues/detail?id=24614&sort=-stars&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars

 

The UAPP music player including a USB audio soft-driver should allow a stock Google Nexus 5 to work with an Apex Glacier USB DAC/amp.

http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/4170#post_10298231

But the Qobuz music player can't use the internal USB audio soft-driver of the UAPP music player.

 

The Qobuz music player can only use the stock Android media framework of the Nexus 5, and there is no native USB audio available on the Google Nexus 5.

 

 

. Modded Google Nexus 5

Apparently a modded Nexus 5 with CyanogenMod 11 (CM11) can work with a USB DAC.

http://forum.xda-developers.com/showpost.php?p=49112102&postcount=55

 

CM11 Nexus 5 using standard Android music player Poweramp (and very likely Qobuz) > USB audio out >> USB OTG adapter cable >> Stoner Acoustics UD110v2 DAC >> FiiO E5 amp >> Audio Technica ATH-M50 headphones

 

 

 

 

I don't know if the CM11 USB audio is compliant with the Apex Glacier.

Thanks Danba, for your extensive reply and for taking the initiative to request USB audio support for the Nexus 5 from Google! Shame it doesn't work yet, but the current standings look good for support in the near future. Can I also vote this request up? (I placed a star in front of the USB audio request - not sure if that's enough...)

Thread Starter 
Got my Dragonfly 1.2, brief play with the Note 3 via USB Audio Player PRO and all working well. Need more time to get a handle on sound, but early impressions favorable. The form-factor, being almost in-line as it were, is just wonderful for this application.

You must scare the pants off of people, the thing looks like a bomb.:eek: I get looks when I attach both a portable DAC and another portable amp to my cellphone.

post #4259 of 5143

I haven't been able to find a straight answer anywhere, so I'll ask you guys. Will the S4 on kitkat work with my Fiio e07k, or will I have to go get an e18?

Thanks
