Any idea if the 7 supports a external DAC out of the box? I am still waiting for USB Support on my Galaxy Nexus - jelly bean on the GN does not natively support it.

Questions go in the Q&A section
The Engadget article "Gear4 speaker dock supports USB audio for Jelly Bean at Google I/O 2012 (hands-on video)!" (I'm not able to post links yet) seems to suggest that JB supports USB audio out.
It does not support standard USB DAC out of the box.
The Samsung Galaxy S3 does.
The Nexus 7 only supports Jelly Bean's android proprietary USB audio, which is a situation where the android computer device is USB client and the DAC is USB host.
I am not sure what google was smoking when they came up with that; in which level of hell does it make sense that the computer would be client to a host DAC? Seriously wtf.
Anyway, standard USB DACs operate as USB clients, because that is logical. The Nexus 7 does not support this, as it is important that Google reinvent the wheel.

Wouldn't Google design it this way so that the device could charged while docked into a USB DAC dock?

Correct, can confirm that neither my E7 or E17 will work with the N7. E7 does work with my S3.

At I/O, two of the big announcements were about the 3.1 release which includes USB host capabilities and the new ADK for open accessory development so you can plug all kinds of things into your device and control them via Android. BUT as far as I can tell the Galaxy Tabs don't have any USB ports to take advantage of either of these advancements. Seems like it is already seriously limited in capability before it even hits the shelves....Thoughts?

Samsung probably sell the USB host controller as a separate accessory and from there, ADK device connects into it. Of course, its better to have it IN IT in the first place, but not a dealbreaker
Wish there was a micro USB port on the tablet, but Samsung did announce at CTIA that they'll have a USB connection kit. Just like the iPad, it's a USB connector that plugs into the Samsung port.
Connecting some dots here. This is pure speculation and it might sound crazy but hear me out.
It has been rumored for a while that Google is adding a dockable desktop mode in Android, maybe similar to the WebTop OS in some Motorola Phones. There have been patents filed and reports claiming that it would release in Jelly Bean. That obviously didn't happen but maybe it is coming in 5.0 (Key Lime Pie?)
Samsung changed the MHL connector from a 5-pin configuration to 11-pin on the Galaxy S3. People were upset because their old MHL adapters would no longer work. Why did they change it? Changing to the 11-pin configuration allows USB Host support (OTG) with HDMI support simultaneously. I have yet to find a connector with both HDMI and USB ports so I'm assuming they are saving this functionality for down the road.
With a desktop mode, more RAM will obviously be needed with increased multitasking. Samsung reportedly upped our S3's to 2GB ram to make it more "future proof" for potential Jelly Bean hardware requirements, which ended up not being even close to required. Perhaps they were thinking that Jelly Bean would bring a desktop mode, but it was saved for a future Android release? Or perhaps they are planning on implementing some sort of Ubuntu for Android functionality?
Thoughts?
Hmm any bored people with experience want to try splicing a 11 pin MHL cord into a OTG and 5 pin MHL? Thinking about it now.. I don't see why it wouldn't be possible unless software is limiting it.. *And at that point is where I guess the devs come in*
This is excellent I just recieved my S3 MHL 11-pin connector, now to try it out tonight with OTG.
Hi danben7, does your mhl cable support simultaneous hdmi and usb-otg? I just ordered the Motorola Lapdock and was hoping to rig a set of cables to enable to use my S3 as a mini-laptop thru the Lapdock.

Nope, unfortuanetely it's not possible. MHL to HDMI needs the charger to be plugged in to the extra port.
Unless in the future samsung release a new MHL connector with OTG together, i don't see it happening. Honestly I don't know why they changed to an 11pin connector.
I totally see this happen for several reasons.
It will be the perfect competitive to Win8
Key Lime pie could suggest a big change since L follows K in the alphabet
At the IO they said the chose ASUS because the like what the do with the transformer series
The new Chrome OS version (v19 and newer) looks like the tablet mode of ICS.
Just add on-screen buttons next to the running apps and enable Widgets
Onskreen and Wind River show that Android can easily support a multi-window mode
Ubuntu on Android looks very promising
The 5 Nexus devices rumor suggest a Key Lime Pie launch before christmas
The 5 Nexus devices will include a ASUS device (I think) -> a ASUS device that is no 7incher will
be a perfect fit for a desktop mode
At least a slow joining between Android and Chrome OS is confirmed by leading Chrome OS developers
I think JB is just a antedated part of the planned yearly release cycle, to compete with Amazone and to
push Android Tablets

As you know, Nexus 7 doesn't have HDMI, and I thought it's Micro USB doesn't support MHL or USB OTG. But, I just found this device which claims it's verified to be compatible with the Nexus 7?
http://www.amazon.com/gp/product/B008CQKM2U/ref=oh_details_o00_s00_i00
Is this possible? If so, could I do mirroring with this device?
The Nexus 7 has been known to support USB OTG for a long time now, which is what that device can be used for, not MHL.
Oh...Ok.. I thought MHL/OTG were one in the same. Gotcha. This line in the description is deceptive then:
"*The MHL function is compatible with most phones. Verified Compatible Devices: --Nexus 7 Tablet"
So, just to confirm, that device will work with the N7, however the HDMI output of it will not work, correct?
That's correct... mhl is a hardware chip and is not on the nexus 7... however the tegra 3 fully spuuports miracast which is a new wifi standard that can mirror over smart and wifi direct enabled TVs... so its coming (someone correct me if I'm wrong)
i found this dock on amazon http://www.amazon.com/Samsung-Galax...id=1378589679&sr=8-1&keywords=multimedia+dock i was wondering if anyone here thinks this dock would work for a nexus. i want to connect a portable hard drive, wireless keyboard, charger and hdmi all in one. this seems to meet my needs.
I've seen a lot of comments about the Nexus 4 not supporting usb OTG devices, so it will probably only work for charging, & maybe not even that.

No, the Nexus 4 does not support USB OTG. The HDMI output probably uses MHL for USB A/V while the Nexus 4 uses SlimPort for USB A/V. This will only be useful for charging; even then it might not charge it due to the MHL chip in it.

OTG is supported in CyanogenMod's 10.1 M2
Now the question is Will CyanogenMod's 10.1 M2 support the Samsung Galaxy Smart Dock?
First of all I'm not the terrible newbie I appear. I logged in this site and it asked me to tie my user name with my google profile and now I'm a 2 post wonder.
Anyway I installed and rooted the Android 5 Lollipop on my Nexus 7 last night and then tried to hook a DAC to it. Previously running USBROM w Timur kernel so I know hardware is fine.
The exact same DAC's are working perfectly under Android L Developer preview on my Nexus 7 2013.
Anybody else try to hook an external USB DAC up?
Also on my USBROM set up I had a Y OTG cable for the DAC and simultaneous charging. I cannot charge through the OTG Y cable now.

I installed Lollipop 5.0 on my Nexus 7 2013 and USB DAC's work perfectly.
I was thinking maybe the root process or kernel patch broke it so I .........
So I checked the md5 checksum on the grouper Nexus 7 2012 and it was fine. I reinstalled it via fastboot and tried again before root. Negative results. No USB DAC is working on my Nexus 7 2012. When you put on headphones and plug in the OTG and DAC it will hiss for a second and then release, like it's trying to connect and then releases the device. I've tried with 2 OTG's and 4 DAC's all of which work on Nexus 7 2013 and 5.0.
Something is broken with USB DAC support on Nexus 7 2012 5.0 update, at least here on my device. Again, yesterday I had USBROM installed and it worked perfectly so I doubt it's a hardware issue.
Can someone else confirm?
yeah just tried a previously working USB sabre mini dac and no bueno.. it has a small light that lights up but nothing for sound output
Yeah, I tried it on E18. It did recognise the DAC (I know because the volume slider popped up for a moment) but there is no sound coming through through the DAC/Amp. Tried USB Audio Player Pro and it worked. Just did the latter to ensure I have the DAC properly connected. I will try it on my son's N7 2013.
I was hoping Android 5 would solve DAC compatibility issues. I noticed that Android version number can affect DAC compatibility-- for instance, the Note 2 talked to the HRT Musicstreamer 2 but not the E17 on Android 4.1.2. On Android 4.3, it's the other way around.
I would try other DACs, I think it is an issue with USB enumeration, as the hardware should compatible. If another DAC works, which I expect many will, then it will be interesting to see which devices work.

I have no less than 6 DAC's at my house and none work on Nexus 7 2012. They all work on Nexus 7 2013. Confirmed with a couple other people I know that DAC support on the 2012 isn't working. It's broken.
Actually not a big deal for me but just reporting what I found in the hopes that they'll fix it. It was one of the major bullet points of Android 5.

Thanks for clarifying.
It sure would be nice to have USB OTG + Charge and full DAC compatibility with Android 5, but at this point I am really thinking I'm over the 2012. I might pick up a 2013 because the Nexus 6 is pretty dissapointing to me.
Hi,
I'm as disappointed as U. Waiting for the updates for ages but got nothing. We've been deceived by Google's promises.
Somebody need to check the kernel first. Seems Google using old kernel which I don't know what it's capable of. Maybe no improvement on the kernel from the features PoV.
I'm monitoring with U on this thread might somebody get enlightenment
I'm sure some dev will fix it. I hope lol. Dash install in need of lollipop

In the interim I have rolled back to USBROM with Timur Kernel. It does everything. USB Audio, 3G dongle, etc.
Although it was a bit of a challenge. Every time I tried to copy the backup of USBROM from my computer to the TWRP directory it would fail saying it couldn't copy data.ext4.win back to the device. Really aggravated me I did a NANDROID backup and couldn't restore it. Then I got smart and moved the file with an adb push from computer to Nexus and then all was well again.
