Teac HA-P50 USB DAC/amp: a standard USB DAC and an Android-specific USB DAC!

Standard USB DAC & Android-specific USB DAC:

A standard USB DAC acts as a USB Device.

A standard USB DAC can work with a PC, a Mac or an Android-powered device acting as a USB Host.

An Android-specific USB DAC acts as a USB Host.

An Android-specific USB DAC can work with an Android-powered device acting as a USB Device.

An Android-specific USB DAC can't work with a PC or a Mac, because a USB Host can't work with another USB Host: USB is a master-slave communication bus, USB communication can only take place between a master device (i.e. USB Host) and a slave device (i.e. USB Device).

"Playback at CD quality (44.1kHz/16-bit) is supported for devices running Android 4.1 or later (this does not guarantee operation for all Android devices)."

High resolution audio playback can be supported using USB Audio Player PRO or USB Audio Recorder PRO.

Android device >> USB OTG cable >> "B" > Teac HA-P50 >> headphones

 

 

 

 

USB powering:

The Teac HA-P50, acting as a USB Host or an Android-specific USB DAC, powers the connected Android device.

 

 

 

A self-powered standard USB DAC (i.e. charging USB DAC), acting as a USB Device, can also power some USB OTG-capable Android device using standard USB ACA (Accessory Charger Adapter) mechanism.

 

A USB OTG device is configured to USB Host mode supplying or drawing power, or USB Device mode by ACA/OTG software/hardware measuring the value of the ID resistor of the USB interface.

 

According to the value of the ID resistor "R"

. the Android device should act as a USB Host, interwork with the USB DAC acting as a USB Device, and supply power to the bus-powered USB DAC

. the Android device should act as a USB Host, interwork with the USB DAC acting as a USB Device, and draw power from an external battery

. the Android device should act as a standalone USB Device, and draw power from an external battery

. the Android device should act as a USB Device, interwork with a USB Host, and draw power from an external power source.

 

Currently, Samsung uses different value of the ID resistor than what is specified in the USB ACA specification (i.e. USB Battery Charging 1.2 specification).

Google and Android device makers should support USB ACA (with standard ID resistor values), only one small step further from USB OTG.

how to use the Fiio e17 with an android phone like the samsung galaxy ones ? I know people have asked this before but I can't seem to find a definite answer, I know I need an OTG cable, which I already have btw but what do I need more?

Plug you OTG cable to the E17 and you phone like this:

 

 

Set the E17 to USB mode and depending on your Android version, all the audio from your phone should be streamed across to the E17 at 16/48k.

Which Samsung Galaxy?

 

The FiiO E17 is reportedly working with Samsung Galaxy S3 / Note2 / S4 / Note3.

http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/5085#post_10713638

 

It can't work with a Galaxy S2, because the S2 doesn't have a functional USB host feature.

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

 

. Required software

It depends on your Android device: native USB Audio (i.e. USB audio-enabled Android device) or eXtream USB audio (i.e. USB host-enabled Android device with the USB Audio Player PRO app available on Google Play store).

 

. Required hardware: Android device, compatible USB DAC, USB OTG cable

The Android device should be a USB On-The-Go (OTG) device, i.e. sometimes a USB host device sometimes a USB peripheral device.

The USB DAC should be a standard USB DAC compliant with PC or Mac.

A USB OTG cable is needed to connect an Android device to a standard USB DAC.

A USB OTG cable is just a USB cable with a "pin 4-connected to-pin 5" micro USB plug, so that the OTG-featured Android device can be configured to USB host mode, able to interwork with a USB peripheral like a USB DAC." [FAQ]

Shame since I have the S2 :( 

 

But honestly I was planning on using it more with my tablet which is the tab pro 10.1... I think someone said it worked with the note 2014 which is kinda the same tablet but with more ram so I'm guessing it would work with the tab pro too?

Weird for some reason it doesn't work on my tab that easily :/

Android noob question: once android L devices are released, does this mean I can finally use my usb dac with the google play music app?

If I understand the situation correctly, not quite. It seems Google was a bit trigger-happy with their announced baked-in support for USB DACs in Android L, and the early reports from people with Android L seem to be a bit of a step back for devices that previously supported USB audio. Looks like you'll still need to find a device that's been confirmed to work before purchasing; we're not quite to the point where you can confidently assume an Android with any given variant of the OS supports USB audio. 

 

Fortunately, it does appear that this is changing, and it's on Google's radar... Can't wait for it to be an automatic feature on all devices!

That sucks. Guess google dropped the ball again >.<

Eh, I'm just glad there's light at the end of the tunnel. I get that they had a million other priorities, and that our group of clamoring enthusiasts is just one of who-knows-how-many. I'm just ready to have it truly up and running ;). In the meantime, there's the fine work that Davy has put in with UAPP to keep us happy!

Nexus 5 on L works flawlessly with my JDS C5D. Tomorrow will confirm the theorem 720
post #5157 of 5426
I received the theorem 10 minutes ago.

Android L+theorem = Facepalm... If you like the chipmunks best combo ever!!!! hahahahahaha

Folks

 

Here in the UK, the Galaxy S3 has come down to the same price as the Moto G 4G (as an upgrade).  

 

Just wondering which would be best choice for USB audio?  Would the Samsung still work with a custom KitKat rom?  

 

Sorry if it's been discussed a zillion times.  Thanks
