For my specific project I'm working on I need to know some things. Involving surround sound and level adjustments. I remember on my PC being able to make level adjustments per speaker. Mainly the sub. Directly to the 7.1 surround card. I've never used a surround DAC.
My question applies to both Windows and Android devices. Using a legit USB Surround DAC, can level adjustments be made per channel . I know I can make eq adjustments in both devices. I know that Android audio out doesn't have surround sound built into it. So there would be no reason for it. But now with these Android boxes and even car radios running Android with in app level adjustments... I've read that using a legit DAC and playing a legit multi channel media will work to its fullest. But nobody really threw down hard core proof.
Nobody has a USB dac they use and can tell me

In have a question about Android and how it handles USB audio. I know that USB has a unified audio layer that is standardized and requires little in order to be seen and operated by the os. Its that reason why most usb audio class devices are simply plug and play, however some devices require add'l drivers for extra fucntions, i.e. dsp functions. What I'm trying to understand is how Android handles usb audio, does it conform to usb audio class stipulations as well, so audio devices are generally plug and play, or is there something extra that would be required?
I'm asking because I hope to get a G-Tablet this Xmas and use it in my car. I could just use the analogue outs but I want something a bit more robust, and was hoping to get an external usb audio device with multiple outputs. Maybe write a driver if needed depending on the complexity, of course. any help would be appreciated.

Hey, I wanted to say that I am really loving x3maniacs build of Ubuntu for tf101, Tubuntu, it's revitalized a piece of hardware I didn't even know needed revitalizing.
I only had one or two questions involving audio. Is there any way to get Jack Audio working on an ARM processor, this one in particular? I've read enough to know that they don't play nice together, but I've read of some success getting it to work with the ARM based Pandaboard through an external audio interface compatible with Ubuntu/Linux. I'd much rather prefer the software way, but anything would be awesome.
And I guess that's part of my second question: Is there any way to get USB midi interfaces or Audio Interfaces recognized? Maybe recognized is the wrong word, because I scanned the ports with my Korg microkey plugged in, and it saw a device labeled KORG, but I think I need to be able to use a midi softsynth like timidity or fluidsynth to have it translate to an application.
I'm already really impressed with this build, and linux in general, I know it's very midi capable, it recognized my psx controllers hooked up with a super dual box pro, and as two seperate midi game controllers no less with fully working thumb axis controllers (which is more than I can say for android).
I should also mention that I'm really interested in this because LMMS (Linux MultiMedia Studio), Audacity, and the Hydrogen sampler all seem to be up and running really well on Tubuntu, I mean I'm more than happy with that. I can even use an adapter to split the microphone input and audio output in the headphone jack so I can plug my guitar, bass, and microphones in and record directly into Audacity. More than I ever could've imagined doing with this hardware.
And anyone who's into audio production or beat making, you should really check out LMMS on Tubuntu, full of instruments, plugin effects, and an Sf2 (soundfont) player, all with really manageble latency considering.
so even though I'm happy where it's at, I'm just wondering if that one small, yet crucial and difficult to work around, piece can be figured out. Jack would open the system up to programs like Ardour, Rosegarden, Musecore (which actually works but crashes when you try to go into preferences and can't play sound, think it's automatically configured to jack or alsa_seq), and Traverso, which all start up, but can't really be used without Jack; or the world of guitar amp modeling, as there's a way to get a guitar signal in.
Sorry for the long post, but I am really excited by the sheer number of things that are already working in this build (not even mentioning GIMP or Libreoffice).
Really, thanks to everyone for their hard work on this. Hope to hear from someone on the issue.
Oh, and I should warn anyone who might try, excessive installing and uninstalling of audio drivers/midi drivers seems to lead to instability in the system, I've reflashed and started from scratch many times in the last few days.
Also, also, I usually found my self in search of snd-seq modprobe file/directory, that seemed to be the thing that couldn't be found and connected to jack most often.
Alright, thanks again.
Hi!
With a computer and an Airport Express you can for example browse Youtube and get the audio distributed through a hifi system via the outputs on the Airport Express.
I would like to do something similar with an Android based platform. However, I need the stereo channels to be optionally split into a 2.1 or 2.2 setup (speakers + one or two subwoofers). Further, I want the Android unit to be set up as a DSP with cross over and equalizers for each channel.
Does anyone know if something like this has been done before?
What existing platform could be suitable, and what mods would need to be done?
Any software suggestions?
Thanks!
I changed the title.
I need a skilled Android developer to look into this for me.
Hey folks,
TLDR at the end
I'm wondering if you can help me please, however I'm not sure if what I want is available. I'm new to this area of Android and I'm finding all the options a bit daunting as I'm not familiar with what is reputable and what is not. For example, I read the thread about the Gearbest MXiii, but when looking in the UK, I found the same box on Amazon, released under 2 different Manufacturer names... Much like if you try to buy a Media PC keyboard.
Anyway, here are the things I hope to do / run:
I want to replace my Windows Desktop that acts as my Media Centre. I use Kodi (Formerly XBMC) 14. I also use Chrome to play Netflix (would replace this with the android app), Spotify - and that's pretty much it. All my Storage is networked so I don't need anything there.
I am hoping to get a powerful machine (Quad core perhaps) with the ability to run lollipop (through AOSP if necessary) that will run Kodi, spotify and the Netflix app. BUT what I am also hoping to do, is run a 5.1 audio setup. I'm under no illusions that this support will be unlikely to be built-in (Although that would definitely be preferable) but will happily buy a USB DAC if we know of a stick that will support it and is not extortionately priced... What complicates things further, is I don't really want to run 5.1. I actually want to run 3.0 ( I don't imaging that makes much difference here, but again - it's not a familiar area to me). The reason being that on my Desktop, I run a centre speaker with the volume controlled separately, because whenever any of my media supports 5.1, when it mixes down to dual channel, I often end up with loud sound effects and low dialogue, which can be trouble when I have both an upstairs and downstairs neighbour....
So.... does anyone have any recommendations based on that?
TLDR;
I'm looking for a Powerful android stick that will support Lollipop through any means and 3.0 Audio as a minimum, even if through a USB Dac

what a crap question
Hi guys I am owner of a Dasaita Max6 with dsp, I would like to have a digital audio output to connect an external amplifier (helix, audison etc). You can help me (I have basic knowledge of electronics), perhaps from the dsp of my Dasaita max6 with an I2s to spdif interface? any forum user did this? thanks (sorry for my bad english)
hello,
there are quite a few solutions to your problem.
i'm using HELIX dsp; music transmitted via TOSLINK to dsp with UAPP and USB to toslink converter; radio, bt, maps via RCA analog input (no issue though, those are LQ signals).
you won't be able to transmit TOSLINK directly unless you know how to extract I2S data from ADAU1401 DSP (yet audio would be limited to 44.1kHz/16bit /android limitation/... so not the best solution).
to get digital audio OUT:
-use Universal Audio Player PRO; it provides 'bit perfect mode' so you get losless quality. it uses it's own USB driver to bypass android limitations.
-use USB to SPDIF converter. there are many solutions like I2SoverUSBv3 (one of the best quality; i'm using it right now); MCHstreamer (versatile); or devices like Topping D10s; E30 -very good DAC with spdif OUT (check audioscience for review). not sure if UAPP works with Topping though.
one issue that might occur - You'll have no software volume control if you'll be using 'bit perfect mode'.
my dasaita / UAPP has no software volume control at all (with or without 'bp mode'). so i need 'helix director' for volume control.
so in general - it's easy and it simply works
Hi ...........Thanks to TNSMANI for moving my post to a better section ,.
Thanks mahtew for helping me find an alternative solution and for the detailed explanation but I would like to have a real digital output if possible (this to have as few distractions as possible driving the car and not have other electronic devices to manage, such as space, costs etc) but not being an electronic technician but only an amateur (very amateur), I knew that from the dsp chip it is possible to do this, perhaps in this beautiful forum there is a technician who solves this problem ...... thanks
(p.s. excuse me for bad english)
you can belive me or not, but your solution will not benefit with much better sound quality. you will be limited to 16bit/44.1kHz which is limit for android sound driver. it might be good but not the best what you can achive. yet it will be better that RCAout
USB data is asynchronous so quite resistive to noise. USB converters are quite good. so you can get HQ digital source.
if you really need SPDIF out from MCU board, then you should find local workshop specialized in repairing electronic devices. it should be quite easy for him to extract i2s data [input to DSP]. yet keep in mind, that you'll still need RCAout for radio and other non android sounds.
.moved to MTCD..
Hi, let me explain better: I would like to know what are the pins (MASTER CLOCK [MCLKI] ,
BIT CLOCK [BCLK] ,WORD CLOCK [LRCK] ,SERIAL DATA [SD DATA OUT] of the dsp ADAU1401A (Dasaita Max6) to connect an I2S card to spdif
thanks

What does the Datasheet tell you? Were you looking for someone else to do the work and explain to you how to do it?
Here's the datasheet, all the info concerning interfacing to the ADA: https://www.analog.com/media/en/technical-documentation/data-sheets/ADAU1401A.pdf
hello, thanks for replying, I only have basic electronics information, I do not have the datashet of the dasaita max6 but I think that the ADAU1401A has activated an analog connection of the front of the rear and of the sub, but is programmed to activate the I2s digital outputs ? if the answer is yes, what are the pins of the digital front? thanks
