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.

Advanced Linux Sound Architecture or ALSA is a Linux kernel component.

http://thewelltemperedcomputer.com/Linux/AudioArchitecture.htm

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:

http://www.slatedroid.com/topic/29289-usb-audio-cards-support-drivers-and-libs/

"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."

Like the overwhelming majority of factory or stock Android devices, with the exception of the Archos G9 tablet and the developer-targeted Texas Instruments Blaze tablet, the factory Linux-powered Logitech Squeezebox Touch does not support USB DACs.

The USB audio is enabled manually on Squeezebox Touch:

http://www.digitalaudioreview.net.a...able-usb-audio-output-on-the-squeezebox-touch

The latest method uses an applet which allows a custom kernel to be installed and provides menus to select the audio output device.

This custom kernel can support 24-bit/192KHz USB DACs. It can also support asynchronous USB DACs which sound theoretically better than the legacy adaptive USB DACs.

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)

http://www.amazon.com/FiiO-Portable-Headph...39194973&sr=8-4

NwAvGuy geek’s verdict: "The biggest compliment I can pay the E7 is I can’t find much I would change for a portable product in this price category."

http://nwavguy.blogspot.fr/2011/05/fiio-e7-usb-dac-amp.html

"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."

http://www.headfonia.com/fiio-e7-portable-dac/

. affordable headphones, like Digitech Pro Monitor Headphones (us$50), clone of Fischer Audio FA-003, Brainwavz HM5 or Lindy Premium Hi-Fi headphones

http://www.jaycar.us/productView.asp?ID=AA2065

"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!"

A USB DAC recommended by Google acts as a USB host, and a Android smartphone / tablet acts as a USB device.

Personally, I prefer the legacy USB audio feature implemented by Samsung on Galaxy S III, which can interwork with a legacy USB DAC like FiiO E7 or ODAC.

The legacy USB audio feature is still specified in the Android specs:

[Samsung Galaxy Nexus] cr0wnest:
I've just realized my notification LED doesn't light up anymore regardless of what the notification is.

I thought it was the lightflow app affecting it so i did an uninstall and rebooted my phone, but the LED still never lit up. What gives?

I'm running stock 4.0.2 unrooted device.

EDIT: Even going into GO SMS Pro and under Test Notification the LED also doesnt light up when it normally does.

EDIT 2: Just reinstalled light flow, re-did all my settings, and then testing the notifications via lightflow doesnt work either. My LED just stays blank. Is this normal?
[Samsung Galaxy Nexus] Stadsport:
Make sure it's turned on in Settings > Display > Flash Notification Light...
[Samsung Galaxy Nexus] returnzer0:
I, too, have consistently had this problem. The only ROM I've been able to get LED notification working with consistently is CM9, but even that has been giving me trouble with the latest nightly.
[Samsung Galaxy Nexus] KWKSLVR:
Did you install an app in between the time it worked and the time it stopped working? If so, try uninstalling it. I've had a time or two on ICS where I've had 3rd party apps conflicting with different things. One time I installed Tweetdeck and it completely killed GPS, couldn't get a lock or anything. I uninstalled Tweetdeck, and GPS came back. Reinstalled, and haven't had a problem since.

Probably unrelated, but technically ICS is still Beta in many ways.
[Samsung Galaxy Nexus] returnzer0:
I've done quite a few things in trying to narrow down the problem, including wiping data, trying different kernels and varying ROMs, and uninstalling any apps that control LED notifications in any way. Nothing has been able to get my LEDs working, except restoring to an older CM9 nightly.
[Samsung Galaxy Nexus] KWKSLVR:
Sounds like there might be something in /system that is preventing LED notifications from working in the newest nightly. I haven't tried CM9 yet, or I'd test it as well to see if it's an issue with the latest nightlies.
[Samsung Galaxy Nexus] returnzer0:
Solved!

It would seem that the newly merged Quiet Hours code includes an option to disable LED notifications as well. It's set for the whole day and is on by default. It's under Settings -> Sounds. Once you disable quiet hours, LED notification works as expected lol.

I want to root my device but I'm wondering what some down sides may be. Also what would be the best way to root? Mashi or what? And I'm looking to increase performance and add additional features like nfc and scrolling wallpaper to name a couple. Thanks for any help!
[AT&T Samsung Galaxy Note I717] roloracer:
no down side to rooting, benefits are more access to different areas of the system, and able to modify parts not accessible before rooting. Now the best way will depend on what you want, if you care about the flash counter then go to my thread in the dev section, if you don't care about the flash counter or warranty then I definitely recommend Da_G's overclocking kernel that also roots the device.
[AT&T Samsung Galaxy Note I717] N3RD420:
Wifi tethering, removing bloatware, blocking adds from free apps, are a couple and flashing custom roms/kernels which enhance performance. You also run the risk of bricking your device... Rooting also voids your warranty. So think carefully before jumping into it.
[AT&T Samsung Galaxy Note I717] zer0nine:
The only downside is losing warranty, really.
[AT&T Samsung Galaxy Note I717] N3RD420:

[AT&T Samsung Galaxy Note I717] corey_r:
What exactly does.increasing the flash counter so? And if I do choose one can I revert back to stock?
[AT&T Samsung Galaxy Note I717] roloracer:
Samsung added a flash counter that when you flash any custom rom /kernel/recovery will keep track of how may times you have flashed firmware supposedly to decide who deny warranty to. You can revert back to stock but not the counter.

Double post sorry
[AT&T Samsung Galaxy Note I717] Truaim:
As Android is based on a linux kernel, rooting your device is allowing yourself access to the very lowest level of system files. Doing so allows you to make alterations that are to your benefit, but of course this is also a vulnerability. These same system files control the well being of your device, and thus malicious applications are capable of corrupting it's files.

Nothing once we get ICS the counter can be reset to 0.

Is that just the root only? or root with over clocking? I did the original root only method and have never had any of those problems. I'm just wondering if it is from the over clocking method and not the root by itself?
[AT&T Samsung Galaxy Note I717] corey_r:
Do I do his through my phone or computer? I'm still confused so any help is appreciated.
[AT&T Samsung Galaxy Note I717] Learic:
It's root only. The benefits of rooting are far more advantageous though. I just deal with the issue above! I can use something like DVDFab and make my own movie files that play fine.

You will have Odin and the tar file on your computer.

Make sure you have the USB drivers for the Note installed and that your phone is recognized by your computer when you hook it up to it.

Here are the USB file:

Download the files you need to root from here (Odin and the tar file):

After you do the above things do this:

1)Open Odin on your computer and plugin your phone.

2)Put your phone in download mode:

power off the phone, then hold volume down and power it on, you'll get a screen asking you to hit vol up to continue, do so. This puts the phone in download mode.

3)Stick the provided pda.tar in the PDA box of Odin3 1.85, flash away!

4)After your phone reboots, Install Superuser from the market.

you are done.

[AT&T Samsung Galaxy Note I717] mokokawi:
its like if i bought another computer device.....like say a laptop home....and after booting it up,it said i dont have administrator rights.and that that if i "unlocked" "my new device"......that the warranty would be void.guess what i would do......screw your damn warranty,im doing what the hell i want to do with it

thats my opinion,and i'm sticking to it : )
[AT&T Samsung Galaxy Note I717] Dillsnik:
Rooting voids warranty, but can't you flash back to unrooted before you would need to return? So, technically it TEMPORARILY voids your warranty...?
[AT&T Samsung Galaxy Note I717] droidal:
No, once you root you make the flash counter go up irreversibly for now, and that voids your warranty. But people are freaking out over nothing. There has not been one single documented case ever that we know of were service has been denied.

Guess you could be the first but I'll take that chance.
[AT&T Samsung Galaxy Note I717] corey_r:
But how do I oc?
[AT&T Samsung Galaxy Note I717] welchertc:
Like droidal said, most people are worried about nothing. Other devices with the flash counter have been returned. If you have to return a device, just make sure it's back to.stock, or smash the **** out of it so they don't even bother to refurbish it. Most reps in stores won't even care to check the flash counter, and Im sure the only place that would care is the place where they actually fix the phones. And if it's on stock firmware, Im sure they wouldn't care about the counter and would just reset the device themselves like they would with any phone, flash counter tripped or not. They need to completely reset the device to sell it as a refurb, so their software to do so is probably way more powerful and surefire than ours. You really have nothing to worry about, and we will eventually have a method to reset the counter anyways.

Rooting or jailbreaking your phone is no longer illegal thanks to that law that passed a while ago, it just voids your warranty as long as custom software is on the device. If you return your device to stock and unroot it, your warranty is back in effect. I broke the screen on my captivate once and was able to still use odin to get back to stock, and they allowed me to use my warranty still.

Please anyone help me oc I'm having trouble understanding Da_Gs thread because I'm a noob
[AT&T Samsung Galaxy Note I717] JZ*:
By rooting this ATT device with this method:

If I just root, without a different kernel, will my device maintain my current folders and setup etc, or will it all be back to "day 1-stock" before i installed my stuff?
[AT&T Samsung Galaxy Note I717] droidal:
I haven't done that one yet corey_r. You have to use the adb commands. I believe that method is a root, OC combo deal. You'll have to try to follow it or read up on adb first or wait till someone that's done it can help you.

I just rooted then used Titanium back up pro to freeze all the att bloat and this thing is flying for me. I'm not going to OC, instead I'll wait for an ICS ROM before I go any further. I used adb a couple times a couple years ago and have done all my flashing since with cwm. good luck.
[AT&T Samsung Galaxy Note I717] jpeg42:
In the first post of his OC thread, Da_G has put the kernel + libraries into cwm. All you need to do is flash this in cwm to have OC.
[AT&T Samsung Galaxy Note I717] corey_r:
So how exactly can that be done? And instead of feeding I just uninstalled bloat with the free version. Mine is also fast but I only have 2 homescreens and just a few apps
[AT&T Samsung Galaxy Note I717] TheMrRoxtar:
The work around is called OTA rootKEEPER and it is a free app in the market that allows you to temporarily show the market your phone is unrooteed when it really is. Very easy.
[AT&T Samsung Galaxy Note I717] Gaugerer:
My main reason for rooting my Note is in order to tether my Galaxy Tab 7.7 WIFI version without paying extra which I think is unfair because I am already paying for the data.

However, a big downside for me would be that I would not be able to watch Sky Go on my Note which costs £40/month and I believe there are other applications which also don't work on a rooted Note.

So, unless there is a foolproof way of avoiding applications being blocked on a rooted Note then it is out of the question for me.

---------- Post added at 01:23 PM ---------- Previous post was at 12:29 PM ----------

Do you know if rootKEEPER will allow Sky Go to work on a rooted Note?
[AT&T Samsung Galaxy Note I717] xplan9:
I noticed in the documentation for rootkeeper it says that it does not work with the Galaxy S2: no mention of the GNote, that makes me think it won't work with the Note. It also mentions not working with Samsung phones in general in the instructions.
[AT&T Samsung Galaxy Note I717] droidal:
Rooting does not change your settings or app data in any way. No matter what method you use.
[AT&T Samsung Galaxy Note I717] Dillsnik:
Thank you all for the detailed explanation. If i purchased through Amazon wireless and then decide to return before 30 days, do you think they will notice the flash counter? Trying to decide if i root and flash or just run it as stock till i decide i am keeping it for sure.
[AT&T Samsung Galaxy Note I717] corey_r:
my note is laggy after root and its always at 400/500 on task manager now where before its 300. how can I fix this?
[AT&T Samsung Galaxy Note I717] jpeg42:
All you did was Root? No other kernel or ROM? Have you installed applications since then? Rooting alone would have absolutely no effect on RAM usage.

---------- Post added at 09:14 AM ---------- Previous post was at 09:11 AM ----------

I don't think a flash counter could void a return even if they knew about it.
[AT&T Samsung Galaxy Note I717] corey_r:
I just rooted using Da_Gs stock root and now im noticing lag were my device was smooth before. Should I unroot and overclock or what? this is bothering me!

If it makes a difference i uninstalled bloat instead of freezing it.
[AT&T Samsung Galaxy Note I717] vivilxw:

Same with me. But then I turned on and off airplane mode, ran Quadrant again and went from low 2000s to 3298 (the highest I've ever gotten).

Seems to me that there's just so many random processes popping up even after clearing memory that I can never really get a consistently high score.
