From Google's own developer page:
 
"AOA 2.0 includes optional support for audio output from an Android device to an accessory. This version of the protocol supports a standard USB audio class interface that is capable of 2 channel 16-bit PCM audio with a bit rate of 44100 Khz. AOA 2.0 is currently limited to this output mode, but additional audio modes may be added in the future."

so it looks like 16/44 is where its at for android, so hopefully most devices will work.

That's great! Now it just actually has to ship out officially so that I can safely order it!
90% of the time I am using it outside I will have a bag in which to put the amp in anyway so, once this can be confirmed to be working, this will be a nice starting tablet.

Got me Nexus 7 this morning - Woohoo!
 
E7 and E17 NOT working, but kinda expected that.
 
Most other stuff working via USB host with the exception of external memory, but will be able to do that once I root it tonight after work.

Congratulations! For me it is morning now >_< last day of vacation training for my degree...
 
So... how is the audio out of the jack? So bad I want to throw it away? Or is it more or less like my laptop: I am using it because I want to listen to things not listen to detail.
 
Have fun rooting, you obviously know to grab stickmount for mounting USB storage. Probably giong to need Jellybean updates for all the apps to work properly, but it seems VLC works directly off the stick for now.
 
Enjoy having it early, there are MANY others who envy you right abut now :D

News has been buzzing this morning that Google has started shipping today.
 
 
Google has started shipping units of the highly anticipated Nexus 7 tablet, but multiple retailers said the tablet has sold out and that they are struggling to fill orders.

GameStop has pulled the Nexus 7 tablet order page from its website, while Adorama and Staples said the tablet had sold out and that they were waiting for additional inventory.

Sound is similar to other Tegra 3 devices ie: not enough to satisfy audiophiles.

Received mine today, loving it so far. Sucks that the E17 can't be used with it though :\ any idea if it's just an issue with these particular DACs like on Symbian or is it down to how USB audio has been implemented?

Down to the implementation. My E7 didn't work either and that works with my S3, N8/808, and Archos G9.

Root does not change anything that would make USB audio work, sorry to say. That requires support at the kernel level and Root does not change that.
 
(for reference mine is rooted, incidentally new users wanting to Root theirs should check out my guide at AndroidNZ.net)

Received my nexus 7 the other day and have had mixed results getting it to actually output audio through the usb host.  I have been able to confirm that the drivers do in fact exist through the usb audio test app for root in the market.  Using that I am able to get test tones to play through my ibasso d6.  As far as getting music to play through any of the player apps, my guess is that we're going to have to wait for the developers to integrate the functionality to get usb audio out with the stock implementation. 
 
Maybe there just is something that I'm missing, but it seems the samsung implementation outputs all sounds systemwide, while google's method is dependent on the apps themselves.  I also tried the test app with my fiio e17 and it was a no go, so it seems that theres still a while to go until usb out works as intended.

Fair enough. I might head down to my local audio store and try a few different DACs now I've received my N7. Should it theoretically just be plug-and-play?

It should be plug n play yes, but obviously it isn't based on my experience and the experience of the user above this post (excellent post BTW). Good news that it could be app related though, rather than an issue at the OS-level.
