Sony Ericsson Xperia Ray

Sandisk 16GB microSD

Both the Galaxy S and Nexus S actually make for decent music players. Alas, battery life leaves a lot to be desired.

I feel like I've further leveled up my SGS. :)

 

Set up:

 

Samsung Galaxy S Captivate

CM7 nightly

32GB CLASS 2 MSDHC

Running AirDroid and Droid VNC

 

With no phone service, I get close to two days of constant use. Through wifi at home, I've essentially turned my SGS in to a dedicated media server. If my external HDD hadn't corrupted, I would have flashed ICS and used USB host to further increase my phones capabilities as a server.

 

Since I don't have any functioning headphones, it's been plugged in to my home theater.

Apparently, the USB audio feature is enabled on factory Samsung Galaxy S III:
 
"I got my sgs3 a few hours ago and just plugged it into my Topping tp30 USB DAC/amp and it's playing audio through it to my speakers!!!"
 
 
Affordable hi-fi rig:
 
music stored on SGS3 > SGS3 player > digital audio stream >> USB cable >> USB DAC/amp Topping TP30 >> speakers

Keep lobbying for the Android USB audio standardisation (i.e. USB DAC as a standard USB device, like a USB mass storage device, for Android smartphone/tablet).

With voodoo you don't need a usb dac. Just go hp out to a receiver, since they have their own dac/amp.

Contrary to the iPhones, the Android phones don’t have a proper analog line out allowing to bypass the internal amplifier chip.

Samsung Galaxy S III interworks with USB DAC/amp FiiO E7:
 
music stored on SGS3 > SGS3 player > digital audio stream >> USB OTG cable >> USB DAC FiiO E7 > amp FiiO E7 >> headphone
 
 
Samsung Galaxy S III triggers a new era of Hi-Fi for the masses with affordable rig:
 
. affordable (subsidized) smartphone
 
. affordable common USB DAC/amp compliant with PC or Mac, like FiiO E7 (us$80)
"Clearly, the E7 is priced very competitively, and I consider it a good product — not some cheap Chinese stuff. Not only is the E7 packed with features, it also comes with a solid build quality, and a solid sound quality as well."
 
. affordable headphones, like Digitech Pro Monitor Headphones (us$50), clone of Fischer Audio FA-003, Brainwavz HM5 or Lindy Premium Hi-Fi headphones
"Now that I've had these for a good month I can honestly say they are my 'New' daily headphones! 
I simple love the music that comes from these headphones.
They are beautifully balanced with sparkly highs that are not offensive to the ears, mid's that introduces a 'fun' factor to the music for all genres and lastly lows that are firm, bassy and goes amazingly deep with out distorting or overpowering the rest of the music. 
The clarity is excellent with a very nice sound stage and for a 'closed' headphone they do sound quite open and spacious!
Isolation is fantastic especially listening to music or playing games at night.
Comfort is excellent and the 'killer' clamp grip slowly eases after regular use! I've listened to these all night and in to the early morning without wanting to take them off!"

The iPhone doesn't have a true line out either. It's irrevent though, as you've mentioned twice that the gs3 will allow for external dacs.

That's interesting, and good news... but of course it's just a start to what hopefully will become widespread. Now we need it to spread to multiple phones, and we need them to support more DAC chipsets other than the old PCM270X series. But I'm happy to see some progress, however small it may be.

 

Can you imagine a time in the future when any random Android device will double as a digital transport? Folks with iPhones are spending big money on something like a Cypher Labs unit, while Android users simply plug in the phone and go. That seems like it would be a big win for Samsung, HTC, and the rest of the Android phone makers, right?

 

But then you put it in context - those companies sell MILLIONS of handsets. Exact numbers are not always easy to find, but I know that Samsung had sold well over 10,000,000 Galaxy S II devices as of late last year. I'm guessing the audiophile community would be a very small percentage of sales in comparison to the overall numbers. So I can see why this feature isn't really given a high priority.

 

Still, one day it will become widespread, and that will be great for us.

I think you don’t use the standard technical term “line out”. 
 
"Line out (signal) refers to an analog electrical signal for connection between audio devices."
 
Line out signal refers to an analog signal at the output of the internal DAC of an Android phone (or an iPhone).

The iPhone/iPod/iPad does have a true line out.

I don't want to derail the thread and start a flame war, but from my experience with my iPod classic 6G, the line out does not bypass the amplifier.

I understand what a "true line out" is and the iPod does not have one. Instead, it just leaves the amplifier at +0db, where on the iPod, it would control the amount of amplification, from -X db to +X db.

Also, instead of posting multiple times, it would be better for the sake of the thread (and my email account that I have to subscribe to this thread) if you edited your posts instead of multi-posting.

Thisi s great but tbh as a portable music device still leaves alot to be desired.  I am switching to the Lumia 900 as my phone when it comes to t-mobile this summer.

The 1st out-of-the-box (i.e. without modding) Android devices able to support USB audio are:
. Samsung Galaxy S III smartphone
. Archos G9 tablet

With a USB host-capable Android smartphone, it’s a software thing.
 
The USB host-capable Android smartphone interacts with USB devices through the USB host controller, a hardware component.
And the USB audio software modules just use the USB flow of data exchanged between USB host and USB device.
 
Android relies on Linux for core system services such as driver model. The Linux kernel acts as an abstraction layer between the hardware and the rest of the software stack.
 
5534201226_7e7d2d90eb_b.jpg
 
Android USB audio software or Advanced Linux Sound Architecture or ALSA is a Linux kernel component.
 
DiagramAlsa.jpg
 
Android 4.0 Ice Cream Sandwich includes the ALSA source code which can be compliant with USB audio class 2 devices allowing for 24 bits / 192 kHz:
"android_kernel_galaxynexus / sound / usb / card.c: "USB Audio Driver for ALSA"
 
The USB audio is enabled on the Ainol Novo 7 Advanced tablet:
 
"We just need 3 base things: 
1st: USB Host support in Android kernel. 
2nd. USB audio driver, in kernel, or compiled as a module. 
3rd. Some logic to switch to USB audio card, or back to internal one."

We should lobby for that.
 
For the time being, the standard USB devices for USB host-capable Android smartphones/tablets are only USB hubs, USB mass storage devices and USB class for human interface devices (for example, mice and keyboards).
 
A lot of people are lobbying for imposing USB DAC as a standard Android USB device, like a standard USB device for every Mac or PC (i.e. we don’t have to request each individual PC manufacturer to add the USB audio capability).

Google should include USB host (and USB audio) on every new Google "Nexus" device, which is supposed to be a reference Android device for others.
